LS3 Swap issues
To make long story short we have a car came in with a strange issue, it has ls3 swap with e38 ECM, car starts fine with no issues how ever it goes into limp mode as soon as it starts. after some digging and troubleshooting I checked pedal vs throttle with engine off ign on both pedal and throttle follow just fine as soon as you start cranking weird things start happening first MAP sensor reads 150kpa while cranking then pedal position changes to 35% and I am not touching the pedal then pedal source changes from MAP A to limited when the car starts map reads 50kpa however pedal stays limited and if you try to go wot fuel cut type will go to ETC and shuts the injectors off??? any ideas ?
