2015 FA20 engine in 2013 car

Oh and it seems to have a stock tune. At least that is what I can tell through techstream. I would reflash it myself but I don't have the mongoose cable. Just one of the amazon mini vci's. ZA1J700C is what it says it has. I have tried to reflash with the cable I have and it says it failed to read calibration. Could it be locked by a tuner?

Changed all fuel injectors too and made sure all the numbers matched on the port and direct both

When replacing the engine we put a thin layer of antiseize between the engine and transmission. Would that cause a grounding issue? May have to end up showing or telling the dealer how to force ecu into programming mode.

You will. Need a tactrix cable to flash tunes to ECU.

You cannot do it with vci cable and the pirate techstream

Found in one of these posts that supposedly the ecu writes exhaust cam gear info on initial startup after reflash. If that's so do you guys think that my car is looking for the old cam gears?

No that's a bit of a myth

I've swapped lots of ECU between cars, reflashed no issues with cams, it's a learner setting. But very occasionally a ECU has a actual hardware problem

Does techstream show and error codes from any module in car is engine, transmission , vsc stability abs, dash cluster ?

There should be a grounding strap that connects them on the top.
