hey guys, i supost to be getting dyno tuned next week, however it is expensive...so i was looking at the zzp lsj pcm. how exactly does this work? they send me a pcm and i send mine back?? and how much does that cost? i noticed it said refundable core charge but not sure what that means...and i cant go a few days without my pcm cuz its a daily driver....and how well does this work? im worried about the humidity and heat differences down here in texas going with a tune like this. what you guys think? any help would be great appreciated. thanks

email them they will awnser all your questions there cool about it...

i emailed them probably over 2 months ago and never got a reply...i plan on calling them tomorrow but i just wanted to hear what other people have had experience with

o shitty i email them all the time and they get back to me usually the same day.... ya there pcm's are good better that stage 2 and any other canned tunes ....but most people here will flame you for getting one sayin its bad..... but when i had mine i never had a problem

what that core charge is, is when they send u a tuned pcm and expect you to return yours to them....they keep a chunk of change during the process in case you decide not to send them ur pcm, that way they wont be out for one!

oh ok thats what i was asking. so i pay $149.99, plus $125, they send me a tuned pcm...then when i get it i mail them back my stock pcm and when they receive it they refund me my $125?? is that correct?

yes sir...thats it!! :twothumbs so r u thinkin u wanna do this instead of go to houston and get a tune for the 60's?

yea cause its alot cheaper, and i know zzp has awesome products and do awesome work...im just worried about 2 things. 1.) how could they accurately tune for my methanol injection. 2.) the humidity and temperture is alot higher here, so im afraid the tuning my effect my car differently...

there is no way for them to tune correctly for meth so that one bad thing about a canned tune.... just give them a list of all your mods and explain where you live too so they can ajust accordingly thats what i did....

Well, they wont be able to do the meth....but as for temp, the computer trims the fuel based on it, so it would trim the scaled maps the same as it would if you drove your car from a 32 degree environment to a 100 degree one

hmm...thats good information. i duno ima call them tomorrow and get some more details. im thinking maybe i can get them to send a base tune to the shop to make it easier on them and save me some money...but who knows. we'll see

Yea i called and talked to them this morning and decided to go ahead and go with it. I order it this afternoon, hopefully it will be here next tuesday or wednesday for i paid for faster shipping....

sweet! :twothumbs just let me know when you can ship the injectors as i will have to let my tuning guy know

sweet! :twothumbs just let me know when you can ship the injectors as i will have to let my tuning guy know
ok my pcm will be here tuesday for sure, and im going to go get my injectors from that performance shop probably that same day...im hoping me and my buddy can get everything hooked up and installed on wednesday if that dont work out then thursday if i have time (me and my g/f are moving thursday into our apartment,so its guna be a busy day) but for what the pcm and 60s take to install it shouldnt be that long to do, so ill keep you updated and hope to have them shipping to you by next thursday or friday....

the zzp pcm runs verry rich just to let you know

Really?? Well it has to be better than the stage 2 tune...plus they are tuning it directly for my modifications..

i kno i have the zzp stage 3

i kno i have the zzp stage 3
how does your car run? well or does it sputter any? cause mine seems to sputter and hesistate alot for some reason...and i have a ton of black smoke out of my exhaust when at WOT

Me too. My 'Balt is stock though. I wonder why that is.

i have the zzp pcm with my setup and eerything seems fine, car runs strong and it doesnt sputter of anything, pulls strong all the way up to 7200rpm.
Im probly going to get it dynotuned sometime, but until then, the zzp setup is a good budget friendly alternative.

Dont do it. Go out and get and get an actual tune from a reputable shop. I was dumb enough to get this and I had a AFR of 13 and I forget how much timing I was running(ask eDubs). Basicly DONT DO IT!

mine runs great....its rich tho....the only problem with mine is my gas gauge is backwards an noone seems to be able to tell me why....bsides it being verry rich i'd say its great

mine runs great....its rich tho....the only problem with mine is my gas gauge is backwards an noone seems to be able to tell me why....bsides it being verry rich i'd say its great

hahahah my gas gauge was the same way when i had mine it was funny shit.... i never figured it out tho....

mine runs great....its rich tho....the only problem with mine is my gas gauge is backwards an noone seems to be able to tell me why....bsides it being verry rich i'd say its great
gas gauge was backwards? what do you mean?

wait, the gas guage is backwards, my car stopped running today and it felt like it was out of gas, but the guage said it was full, so i thought it was broken and me and a friend pushed it to his house, is it possible that maybe my car was out of gas, since it looked like it was really really full?

yea it is i guess...when i fill mine up it reads empty....i've called zzp after i installed it an they wanted me to send in my pcm i just told them i'd deal with it for now and they can research it an call me when they figure out the problem

WTF? so you filled up your car and your gas gauge said it was dead empty?? yea i hope i dont have that issue cause i dotn want to go through the trouble of returning it and everything

yea i'm contemplating asking zoomer what is up because the other guy jus said he had the same problem....its wierd and annoying but doesnt affect performance and i couldnt really send it back considering my car was off the road for a week waiting to get it back along with the stage kit so i just told them to research the issue an call me when they had a solution...but it is verry annoying but the kit does run verry well

zzp should def figure out wtf is with the as guage. I went through a massivly lame ordeal and had to push my car 5 blocks thatnks to them. Oh well. At least the car runs nice. They should def figure out what the problem is and how to fix this. Anyone know if this will go away if i get the car dynotuned?

so thats wat the problem was huh zay?

and i believe it is somethin in the pcm with their reflash...so if you get it dyno tuned an the reflash the pcm an check everything i'm sure they are probably just missing something..ima pm zooomer the link to this thread so he see's otheres are having this problem as well

the 05-06 ecm is different than the 07 and if you interchange them you will get a backwards reading gas gauge...but thats all no harm... how does no one know this? i did a search and found your answer in under 20 seconds...


another thing thats funny how did you guys actually run out of gas...:nono: the farther you drove the more gas you got!!! that didnt seem odd to you :lol:

i havent ran out of gas but is there no way to fix it....and they tune for our vin's and year so wouldnt they know that? and my pcm is the one i sent to them that they reflashed an sent back...its not one of their pcm's

well then it was obviously loaded with a canned tune that was from a 05-06 model i have there tune as well and i sent them my ecm also and mine is right i have a 07 and it reads normally... i dont know if you noticed but for a while on the website they had it only availible for 05-06 that was beacause of this issue... well i had someother issues with them like selling me a high flow dp that would throw a 420 code... so what they offered mye was to do a cat code delete at no charge if they could barrow my pcm to do a 07-tune this was early 07 and which i also recieved there canned tune at a discounted rate... dont know how much this helps you but yeah...

i have an 06 thats the point...they musta sent me a tune from 07..i called them an they said they had no idea wat could have caused it

i have an 06 thats the point...they musta sent me a tune from 07..i called them an they said they had no idea wat could have caused it

thats funny they should know exactly what caused it... i hope there not giving you thee old "cold shoulder" hoping you'll go away... it's not right and im sure you paid good money to do it right... if they dont even know what they did to your ecm, that would scare the shit out of me... what else did they forget/dont know what they did with that tune... :thumbsdow

well i pm'd zooomer with a link to this thread and i'm hoping i can get it fixed like the others on here...the stage kit from them is great an i'm pretty happy with their products...and i'm positive that its not intentional...i'm sure zooomer will get back to me

yeah zzp can be really great... and i do love there product too... and theyve been around for awhile... so theyre probably not going anywhere soon and i like that as well...

hmm this worries me. Im calling them right now cause my SS is an 06 and i want to make sure they have this kink worked out before i install it in my car cause i dont want my gas gauge to be doing that, even if it doesnt affect the actually driving of my car.

well of course i didnt get ahold of zzp...for some reason their phone always has a busy signal. i just tracked the pcm and its going to be here tomorrow afternoon but i doubt i will get everything installed tomorrow (pcm and 60s) but hopefully wednesday or thursday. ill keep you guys updated to see how well it works for me.

?? due to the heat, shoudl i go up a pulley size? im seriously thinking about this for i believe my car actually pulled harder with my stage 2 pulley on. and i know its been proven with zzp's pcm that they make more power with the 3" pulley versues a smaller one..

i'll race my buddy he has a gm stage 2 with a 2.9 pulley..an no exhaust....i'll race him...i now have a full exhuast with a zzp stage 3..........afterwards i'll let you kno if i beat him or not an how close it was

sweet. a vid would be nice too. im thinking about upgrading my heat exchanger also...im trying to get the engine as cooled as possible, cause in texas it gets pretty much 100 degrees everyday during the summer. do yall know which heat exchanger has the built in coolant tank to lower temps even more?? cause i dont wanna run the dual pass mod cause of the surge tank....

the Heat exchangers are only 60% efficient so your only getting another 60% cooler....if you want max cooling and power....spend another 200 an get the meth kit from AIS....you DO NOT need a tune for it however you'd put more power down if you did tune for it but if you don't then it keeps your engine safe an all it does is spray a mix of water/methanol into your engine an the water helps keep it cool while the methanol boosts your octane which pretty much eliminates the occassional (bad gas) that we get that pings every now an again....the meth over the h/e is far more cost effective

x2:cssNET:

man, it really sucks that you spent all that time typing and explaining that for me when all you had to REALLY do was look below in my sig and you would have noticed AIS STAGE 1 ....:lol:

oh and to add to that, if you go to the customers pictures on AIS's website, you MIGHT find my car there...hahaha!!! http://www.alcoholinjectionsystems.com/a58/Kelby-West-Of-Winnie,-Texas-AIS-Methanol-Injected-Custom-2006-Cobalt-SS/article_info.html

then if you have an h/e and meth you should have no worries of heat problems....now my dam car is studdering in first and second an then smoothing out ....its only in the beginning of the first an second gear...once she gets going she is good or if i slip the clutch a bit so when it bites it is at a higher rpm its good also....i just installed the zzp header/dp combo so is it possible that the pcm/ecu is still learning the new setup?...and i had previously gapped my plugs at .40 and with the zzp stage 3 it ran great with just a cat-back but now its doing this so maybe i just need to regap?...any help would be appreciated

did you guys need to do a case relearn and or security relearn with the re flashed PCM

you only need to do a case relearn if you order their pcm an keep yours as well...if you send them your pcm that came in the car then you do not have to do a case relearn

do you guys know if you should disconnect the battery when installing the new pcm or what?

you should have disconnected it when you removed it to begin with so yes disconnect it before you hook it back up....then reconnect it and pull your fuel fuse so you can drain your fuel lines so you can begin dismantling your injectors an fuel rail....once the car idles an shuts off (no fuel)...then disconnect the batter an put the fuse back in an start puttin in that stage kit....btw zzp said they fixed the fuel gauge backwards problem....i'm sending mine in at the end of the week to get reflashed an fix it

UPDATE: i got my 60s installed and the zzp pcm. car runs so smooth and i can definetly feel it pulling alot harder in 2nd car, cause 1st gear goes by pretty quickly..haha however my fuel gauge is backwards, so i might winde up sending it off to them again for them to fix it, i just cant go a week without my car since its my daily driver. so far everythings great though, a lil rich of a tune, buts its waaay better then my stage 2 tune. overall, im satisfied.

well, the car started running like crap. i was quite irritated. the car was hesitating and bogging down terribly when shifting. so what i did was unhook my methanol and it seemed to make a big difference. so now im lost....im bout ready to sale everything!!!

you might be running to high of a meth/water mixture or you could have your injection time wrong also or even to big of a nozzle

You need to find someone with HPTuners near you. They can read the ZZP PCM and then make changes to your PCM. Once they do that, you can fine tune it to run perfect.

Then you can send ZZP back the old PCM and call it a day ;)

ive already sent back my old pcm to get my $125 back. haha, and literally no one near me has hptuners. ive made a post in my area and not one reply. plus a no a quite a few people from the houston area and they know no one either.

im thinking the injection time. the mixture is 50/50, and the nozzle has to be the right size cause rodney at AIS said it was for my car and my application type.

Kwest i said earlier...with your new setup you have a higher boost psi..your stage 1 should start spraying at about 70% of your max boost...did you recalibrate it for your higher boosting?

i talked to rodney yesterday, i think we came to the conclusion that my switch is not working correctly. i could have stripped it so ima get a new one and see how things go. any reccomendations on a cold air intake? which one are people not getting check engine lights with?

most ppl go with Injen...the K&N intakes appear smaller tho i don't know if they actually are...they say they airbox mod is just as good but i like the look of injen over any others out there anyway

i thought injen threw check engine lights?? dont some people claim that?hows the rebel auto worx? is that throwing codes?

good luck even gettin anything from rebel...i don't think they have been to active shipping things lately.....any CAI has the potential to throw codes i think it just depends on the car...i have an Injen and so does my friend an we never threw any codes due to the CAI

really...hmm. well threw my zzp pcm, shouldnt that have tuned it for my cold air intake and my highflow cat?? so theoretically i shouldnt have any codes?

yea if you got them to tune for it then yea ...but remember they have different flow rates as you go to their website an simulate a check out for the pcm they offer an you'll see what i mean...but yea essentially you should be much more less likely to have problems since you are already tuned for a cai in one manner or another...feel free...the Injen CAI's look bigger than the K&N's tho....like the K&N's are 2 inch an the injens are like 2.5....i'm not sure if thats true dimensions but gives you an idea what they look like in difference cuz a friend also has the K&N typhoon CAI
