Ok I've asked before in other threads, but got no answer. IS THE STAGE 3 PCM TUNABLE!?!? I need something to switch between high octane mod and low octane mode, but I don't want to waste my money on the PCM if I can't tune it!

Good question so here is a free bump.

I'm curious too. I want to know if you can get in there and enable the A/C.

I have a feeling this is going to become the stage 3 Q&A thread.

buy one and let us know

yeah I"m just a tad bit interested in that

well if you the user can adjust the rev limit with the push of the throttle then im assuming that it can be tuned just as easily as the normal pcm just that this newer one is an updated version with more abilities

I think they locked it and thats one of the reasones for giving you a whole new PCM.

it was always intended to be a hotswap pcm though since news came out about it so it wouldnt make sense to say here is an offroad kit oh by the way you cant mess with it

Very true. So nobody knows for sure yet hah? I guess we'll have to wait for some people to actualy install it.

I'm getting this PCM regardless. How many PCMs come from the factory ready for nitrous and 100 octane gas.

It's by far one of the sickest PCMs to come from the factory.
It's perfect for the guys with 2.9" pulleys. :guns:

Mopar stage 3 has an octane mode switch.

ok installed it today... hp tuners doesn't connect ... blah... scanner read it,, and it comes up in the info screen
vin: YYYYYYYYYYYYY
model: unknown...

sucks.. but so far it seems ok with my 60's but my car is still up on jack stands... so I'll hopefully know in a little while.. BTW that rev adjust thing is pretty cool watchin the tach move

dude LET US KNOW how this thing is get a freakin video.

Maybe Keith at HPTuners will find a way to get into it for us. Just as him.

I will... gonna make a thread on the hp forums,,..

Pcm is pretty cool, cept for the fact I"m running 60's and 2.55 pulley on the thing... pulls nice and adjustable rev limit is pretty damn cool... only prob is my AFR is less than 10.0:1 the second I get past 50% throttle... tomorrow I might throw in some race gas and test out HOM. and see how that feels... but finally my car idles correctly (somehow) and it was my other PCM was fried from too many reflashes I guess... >100 times

Less than 10.0:1? Eeek. Can you imagine the difference if you could get it to 12.0:1. :twothumbs

yeah thats why I hope I can tune the damn thing....

Well I know how it pulls I was running a 2.55 pulley and every other bolt on made for the car for quite some time... just my stock PCM got fubared and the car wouldn't hold idle when i would come to stop... this is with either stock injectors and flash, gm stg II flash and 42s and anything inbtwn... so I after changing all the gaskets on my car thinking it was vaccuum leak related... I changed the PCM and wala... runs fine now... even with the 60s' off idle bogs pretty bad but after that its ok

Any word on when the stage3 PCM will be unlocked?

What is the potential compared to the "stock" PCM.

dunno at this moment... no response on HP forum yet... hopefully figure it out this weekend.. and I"ll let you guys know/.

Very interesting. I hope HP Tuners will unlock it. It would be awesome to swap octane maps and adjust the rev limiter without hooking up a computer.

would it be possible to scan all the data from the Stage 3 tune it and keep the rev adjustment and HOM and load it onto a reg pcm?

that I don't think so... but ya never know at this point

has anybody else installed this yet,.,, or tried it with hp... someone besides me must have damnit

Stage 3 is supposed to stop the AC from working... has any with the stage 3 in already seen this happening?

Yes you can tune stage 3 and switch from high octane to low octane mode. It tells you that at www.crateenginedepot.com

mm...listening

ummm thats not tuning my friend.. that's user selective.. a bit different...

I mean like change Injector sizes i.e. 60 lbers... change timing maps... VE tuning that sorta thing...
it does disable the A/C,,, but since I don't have a/c anymore... doesn't really matter.

but one thing I did notice.. I don't have my second o2 sensor in right now... no CEL... so going catless...
but it looks like the turbo project with RIPP is going to happen.. so Ill keep ya guys posted

know what when it is unlocked try and see if you can re-enable the a/c that would be a plus all by itself. that way once the car is out of warrenty you never have to go back.

eh,.. I don't have ac anyway, I just want to be able to tune for my 60 lbers

RIPP has an amazing 60 trim SRT-4.. 520whp lol... i emailed intense and asked them if it was possible to scan the Stage 3 PCM and tune that and keep the rev adjustment and HOM and they said they probably could but don't have a Stage 3 PCM yet.. but if that is possible and you can buy the PCM from intense with the new benefits of the Stage 3 PCM with a custom tune that would be awesome and probably would take a hit on GM's sale of the Stage 3 PCM

yeah Ripp just sold the SRT-4 and picked up a FD3S rx-7 .. will be beasting very soon, They also have a skylin r-33 GTR spec-V that's up around 800 awhp... can't wait to see what they could do for us cobalts.

Thats really Rich right? are you getting a Rich CEL ?

nope no CEL's I think stg III disables the emissions dtc's since I have no second 02 sensor and drove for 4 days so far with no CEL.

bump for an old thread.. i've ordered the stage 3 pcm.. do code scanners read this pcm?? or do they come up with nothing? i want to put like an aero foce type gauge setup.. but if this pcm is locked.. would that even work? i'm also planning on running a 50 shot with this pcm.. anyone done that yet?

It's a completely different PCM... does not work with hp tuners... you can scan.. but can't read or write to it. It does work with the aeroforce, I know cause I had one.

ok thats cool, as long as scan tools and aeroforce still reads from it i'll be all set.

is anything required when ""swapping the PCM's""

what is a "case re-learn", have heard the term and was under the influence that is required to swap the PCM's?

I didn't need to do a case relearn on mine just plugged and went.. just make sure you disconnect your battery before starting to disconnect the PCM... don't want to fry it

nice.. no case re-learn is even better..

So there is nothing to do but just hook it up and that's it? I know u installed yours but is there any truth to this besides your car still running so far. Why did they make such a big deal about the stage 2 pcm doing the CASE relaern or the intense kits if these pcm's don't know the crank position

The stage 3 pcm is plug and play. It honestly takes about 10 minutes to change the pcm's out. Thats with unhooking the battery and hooking it back up again.

i kno the stage 3 pcm from intense is tunable but i dunno about the one from gm??

cause with the intense PCM's if you didn't send yours in to be tuned.. you basically got someone elses that wasn't in your car before.. thats why you'd have to do the CASE relearn.. but the stg III PCM from GM.. is well a GM part and designed to be plug & play.
and I"ve swapped PCM about 3 times in one weekend and never had to do the case relearn.

ok i finally got my pcm.. does it just disable the a/c?? or does it disable to heat too? cause it's still kinda cold here but i wanna be able to test it out.

just ac

oh sweet... i'm gonna go install it right now...

just remember to disconnect your battery before you start doing anything

hey does anyone here know where i can get my car hp tuned i live in el paso tx

Look in the "Tuning" section. There is a sticky with a list and a Frapper Map of members with HP Tuners. The Frapper Map has more people than the list since Jim is no longer on the site.

Do have to give a vin number when buying the stage 3? The reason I ask is that it is said to void your warranty. If you don't have to provide a vin then I don't know why they say it will void you warranty because you could just take the computer out and put the stock computer back in for warranty visits.

i didn't have to...it was kinda weird but whatever.. i'll be installin later this week i hope.. we had some surprise snow the other day.

yeah I just had to give them the year of the car. The PCM shows an unknown VIN# like YYYYYYYYYYYY.

yep, just take it out.....
I have one I'm not gonna use ;) its for 06-07 if anyone wants to make an offer

finally got the thing installed today.. this is the best pcm ever.. it's so cool to set your own rev limiter.. i got on it a little bit today.. seems to pull pretty good.. can't wait for the roads to be dry so i can take it on the highway. i'm seeing crazy ass gas mpg though.... is that normal? not that i'm complaining or anything lol.

what other parts are you guys running with the stage 3 pcm from gm?

i got a 2.8 inch pulley.. 42lb injectors, intake, 3 inch exhaust. yea i know.. people are gonna say i'm maxing out my injectors. my car's been running fine on them, so no need for me to change them yet.. although people have been running 60's with this pcm.. but i'm worried about plugs lol..

it didn't control the 60's at all man.. AFR was waaaaay rich... but don't set your rev limiter over 7400 rpm MAx... or kiss your valvetrain goodbye

oh.. i thought it ran ok with the 60's.. guess not.. . i set it at 7250.. so i can still shift at 7 and not hit the limiter.

it didn't control the 60's at all man.. AFR was waaaaay rich... but don't set your rev limiter over 7400 rpm MAx... or kiss your valvetrain goodbye

so what are u running now...42's?

oh.. i thought it ran ok with the 60's.. guess not.. . i set it at 7250.. so i can still shift at 7 and not hit the limiter.

I didn't log it so I can't be certain what the readings were. It ran, better than the stock setting with 60's did.
Setting the limiter that high makes perfect sense. Just remember not to abuse it by taking the car to the limiter when its at 7250.

i don't run my car that high in the rpms very often.. unless i'm at the track. anyone else seeing more boost with this pcm?? i don't think it bleeds boost off in higher rpms.. cause on one highway run i saw 20psi.. not sure why.. may have been the weather.. but i thought it was weird.

So the Stage 3 PCM can't handle the 60's? I would love to have HOM and the rev limit adjustment. But if it cant handle the 60's which i already have installed in my car with the Intense stage 5 tune i might as well stick with that

Any new news?
