CASE Learn on a RR?

[N0DIH]

I have a P1336 on my RR and need to learn it, can I with a Tech2? VIN won't program either, so EFILive Scan always asks for a VIN when I launch it

I can't do it with the EFILive DVT tool.

Thanks!

Uhm, not to seem dim but, what is the DVT? I routinely run the Crank Position Relearm and put the VIN in the RR using the scan tool.

Scan tool function?

Sorry I am still relying on 7.5 to do the day to day stuff to keep my customers happy. I just looked at my R&D setup with V8 and I understand now.

Scan tool function?

yes

I am 99% sure that CASE relearn will not work in the RoadRunner because the RoadRunner does not contain a 'real' flash memory device which is what the PCM uses to store the CASE data.

my RR has the option to switch to "flash memory".
is this not the same as a stock PCM?

Hmmm...I'm sure I've performed CASE relearn with my RR.

Lets just say my RR isn't on a LS1 PCM...

I just can't seem to get it to work with it....

Would this explain why I continue to get a P1336 (CKP System Variation Not Learned) while using the RoadRunner? The behavior is...

- perform CASE learn
- SES light goes out
- clear powertrain codes
- drive vehicle
- stop/start vehicle several times
- eventually P1336 sets again
- perform CASE learn...etc

I first noticed this issue after putting in a custom OS. I'll flash a non RoadRunner PCM, put it in the vehicle, perform a CASE learn, and then see what happens from there.

It's also worth mentioning that this is an early small block engine with LS1 coil per cylinder. During this P1336 issue (which did not show up a the dyno), the vehicle still made clean dyno pulls yesterday.

Any thoughts? Experiences?
