Hi Guys, I'm freaking a little bit but heres the story. Just got my OTTP Stage 2 with refundable core, everything was done and plugged in my new ECU, won't even turn over. Is due to my car needing a CASE Relearn? I've searched and the other threads said Hp tuners and dealerships can do it but I've also read in threads that dealerships say they'll erase the tune on there? Just need some advice on this. Thanks!

 

theres a thread on here... security relearn? Um something about turning it to on for x minutes off then on again. let me see if i can find it.

ty I tried last night but all the things I read about security relearn are mostly used on turbo balts while mine is 06' ss/sc. I'm gonna try it again though

 

You need a case relearn which can be done by the dealer,or someone with hp.

Install a scan tool.
Monitor the ECM for DTCs with a scan tool. If other DTCs are set, except DTC P0315, refer to Diagnostic Trouble Code (DTC) List - Vehicle for the applicable DTC that set.
With a scan tool, select the CKP system variation learn procedure and perform the following: 3.1. Observe the fuel cut-off for the applicable engine.

3.2. Block the drive wheels.

3.3. Set the parking brake.

3.4. Place the vehicle's transmission in Park or Neutral.

3.5. Turn the air conditioning (A/C) OFF.

3.6. Cycle the ignition from OFF to ON.

3.7. Apply and hold the brake pedal for the duration of the procedure.

3.8. Start and idle the engine.

3.9. Accelerate to wide open throttle (WOT). The engine should not accelerate beyond the calibrated fuel cut-off RPM value noted in step 3.1. Release the throttle immediately if the value is exceeded.


Important: While the learn procedure is in progress, release the throttle immediately when the engine starts to decelerate. The engine control is returned to the operator and the engine responds to throttle position after the learn procedure is complete.


3.10. Release the throttle when fuel cut-off occurs.

The scan tool displays Learn Status: Learned this Ignition. If the scan tool indicates that DTC P0315 ran and passed, the CKP variation learn procedure is complete. If the scan tool indicates DTC P0315 failed or did not run, refer to DTC P0315 . If any other DTCs set, refer to Diagnostic Trouble Code (DTC) List - Vehicle for the applicable DTC that set.
Turn OFF the ignition for 30 seconds after the learn procedure is completed successfully.

 

ya I wasnt sure on the lsj stuff...but ^ sounds like it should work

 

Is that what needs to be done with HPT as well? or can I just put the new pcm in, plug in hpt and put the info in?

 

Installed a new zzp 2.0 pcm about 3 months ago didn't do case relearn... just finished clutch install now she don't turn over DTC p0315 comes up

 

ya the ecm replacement is a B.

I had to have tech 2 tool to do the relearn w/ the car. You can't do it all via drop ship or hpt.
