wait so this is recommended for our V's? I dont understand sorry.

 

[CVP33]

I am looking into buying a stock PCM (for dealer visits) and a tuned PCM for everyday driving. If I do so I will need to have a Crankshaft Position relearn done everytime I switch or I can drive around with the check engine light on.

 

[ctsvett]

you can relear the CKP with efilive... And yes, when you swap PCMs you DO need to relearn the CKP.

That sucks..I thought you only had to program the CKP the first time. I'm starting to lean toward the injector-style tuners as a result of dealership-paranoia. I had a stock ECU for my Audi turbo, only took 3 mins to swap boxes and no other issues to deal with. I hope StealthV comes out with his injector before Spring or I'll need to do the Diablosport/Superchips handheld route. I'd rather switch to a stock tune via the OBD port than need to go through the various steps/costs of having an extra ECU.
Ve good,

The CASE learn procedure is only for misfire monitoring. The procedure essentially enables misfire monitoring. It seems a simple solution would be to have the tuner of the ECM disable the CASE learn code (P1336, I think) from illuminating the MIL.

now wait guys....i'm not the expert but the CPK needs learned ONCE and once only. Having swapped PCMs many times for flashes, I never ever had to redo this no matter how many times it was flashes. The BRAND NEW one fresh out of the box needed it, but that was it, 1 time. I don't know why some folks have had to do it more often....

negative Urby, I have 2 PCMs and whenever I swap out one, I have to do a CPK relearn. It holds true if you only have 1 PCM, but multiples need to relearn. Rick?

guys,
think about it logically.

The CKP memorizes the position of the crankshaft. If a PCM is out of the car and the engine spins, it does not know where the crankshaft is in its rotation without a program. So, if the engine runs without a PCM in it, when you put that PCM back in, you must reprogram it.

Rick, correct me if I am wrong.

It would be best for our resident expert tech to answer as the title of the thread was originally directed that way.

 

[ctsvett]

Rick,
Thats you!

[StealthV]

Inquiring minds want to know the answer, including me.

 

[CVP33]

Rick,

I appreciated your email. I replied. Thanks for looking out for me as usual.

I remember that thread. Be careful Rick, people are going to start thinking your as sensitive as I am. You sure we can't fly you down here in November??? That would sure take care of my tune problems. Maybe you could make Derek your Texas supplier???? Now that's thought.:bouncy:

hehe
