Trouble with engine starting LS2 Standalone
Trouble with engine starting LS2 Standalone I have an LS2 from a TBSS with 58x E67 ecu. Harness is from Current Performance. Original ECU was ruined and I acquired another e67. VATS was removed and it was written with a calibration from a CTS-V with manual trans. Motor would start with original ECU, but now I can only get it to spin over. I sputters like it wants to start, then dies. Getting error p0315 and p0335 for Crank position sensor. I know there is a relearn, but I cant do that without getting the car to start.
Should I not be able to use this ECU since it didn't originally come from an LS2 even though its an E67 setup as v8 with manual trans?

as long as u performed the correct segment swap it should work. Ive seen this happin on a few segment swaps ive done. Sometimes its best to flash back to original and retry. Maybe crank sensor went bad? checked harness to make sure its plugged in? didn't mess up any pins swapping pcm?
O yea make sure with the new pcm that u have the vats removed, starter faults disabled. That will keep one from starting as well.

starter faults are in the engine diagnostic section. I had a gen5 5.3 swapped into a c10 that would just turn over and not fire. Disabled starter faults and fired right up. Also I wanna say to completely remove vats a write entire needs done.
never mind I just looked over my ls2 tune. start fault disable is located under the main OS table next to vats delete. also there are 2 other tables for it under SYSTEM tab general section. Try disabling all of them and see what happins
