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!! 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! 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

 

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

 

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

 

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?
