Put in the new pcm with my stage two. Wont turn over. No security light. Help please. To my understanding i cant do the relearn without the security light, which isnt going on at all.

 

Helppp!

 

Anyone. Freaking frustrated over here any help would be appreciated!

 

try the relearn. if it doesnt work call zzp, or get a hptune

 

I dont know how to get the security lock to appear, then i try the relarn, right?

 

Does it turn over with your original pcm ?

 

Got it to turn over with new... but it isnt right. Keeps revving on its own at around 1k...

 

vacuum leak?

 

How can i check for/ fix that?

Oh and supercharger boost guage is staying at exact 0 no matter what

 

definitely a vac leak then. check for rotted or broken vacuum lines

 

Is the only thing you changed the PCM? Because if so, it definitely isn't a vacuum leak

 

Yeah I guess he’s right^ tho it still could technically be a major leak if the gauge is reading 0 vacuum... try the stock pcm and see how it runs

 

I had one break but i thought i fixed it? I also installed fuel injectors, spark plugs, and a smaller pulley all at the same time. Is it safe to drive with an idle issue? And how do i test" fix a vacuum leak (kinda a noob)

 

it might not be that. id try starting it with the stock pcm first if you have it, but dont drive it on the stock pcm. if its doing the same thing you just gonna search around for a hissing noise and replace that line. idk if it could be injector seals or anything though. any codes?

 

P0315 crankshaft position system variant not learned.

 

id wait until morning and bump this for someone who knows more than me. sorry haha

 

Haha alright man. Thanks for your help. Trying to get this done tonight. I guess ill just keep going till i figure it out, who knows, by then someone who has had this happen may hop on! Again, thanks!

 

i guess it is only 11:14 there...unless? idk what dst it is but i dont think arizona follows it...anyways its 1:14 here

 

You know that vacuum hose on top of the intake manifold between the supercharger and fuel injectors ? Check that out and trace it make sure u didn't break it loose somewhere...

 

Need more info wat did u change?? Did u get a zzp stage kit with injectors..cuz i would think u might have cut one...i did it...i got rid of that crap and put some good old 90 derometer orings in. U should have to lines coming off the bypass valve start there see if u have a cracked hose.

 

not quite sure which hose you mean? but illl see if i can figure it out!
yes i did get the stage kit with the injectors... how would i check for and fix a cut one...?

 

OOh and the boost guagge stays at 0 at all times. Where driving, off, on, idling, or reving. And my speedometer also stays at 00 at all times.

 

hmmmmmmm, are you sure zzp didn't send you the wrong pcm? i have heard of this happening before

 

is there a chance you put the bypass valve on backwards? A buddy of mine told me he did that, wasn't pushing any boost, took him forever to figure it out, wouldn't explain the speedometer though

 

if they didnt disable the "vats" on the pcm lik in hptuners then the car wont turn over either...but idk how they mess with the pcm's at zzp so it may be sumtin totally differnt
