1970 CUDA - 6.4L GEN III Engine SWAP - WOT Issues

Do you have drive by wire throttle. You may need to learn the pedal position. Disconnect battery, reconnect hold down on pedal and turn key to on. Let off pedal turn key to on and then to start

Hi, thanks for your help. Yes, it is a drive by wire throttle. We did the learn procedure that you described above, but it didn't solve the problem. On the other hand, I found an Instruction Sheet from MOPAR that explaine the Pedal Learn process as follow:

Pedal Learn Visit a MOPAR dealer to perform the pedal learn function below:
1. Connect a battery charger to the vehicle.
2. Cycle ignition to RUN.
3. Connect the scan tool (wiTECH 2.0).
4. Enter VIN as “11111111111111111”.
5. Select “2015” and “LA” (Challenger) as vehicle from drop down menus.
6. Select “PCM.”
7. Select “Misc Functions.”
8. Select “Learn ETC.”
9. Follow on-screen instructions.
10. Cycle ignition key after the successful routine completion.

I'm trying to buy the wiTECH scanner (I'm from Argentina) and then perform these steps.
