Hey guy this is my first post here, my car is a 97 ek coupe, its obd2a with a jumperharness on the distributor and the ecu. The ecu is a chipped p28 with a neptune/ demon combo. Running dsm450cc injectors, with dsm resistor box soldered and heatshrinked in. It runs crazy rich, and wont datalog or anything, so my buddy plugged up his p06 with the neptune and demon combo and it ran perfect and he could pull codes, and datalog. Not even a mile down the road, after he put his ecu back in his car, it started doing exactly what my car is doing with my ecu???? I'm
stumped on this? Any help would be greatly appreciated

Engine? All Mods? What is on the P28?

Don't understand why you aren't contacting either the person who tuned it, sold it to you, or someplace like HRTuning. Those would be the first people I would be talking to. Sounds to me like your car is corrupting ECUs somehow if putting a good one in it essentially destroyed it.

It hasn't been tuned yet only a basemap made. The motor is a jdm d15b vtec obd1 motor, boosted on stock internals, well almost boosted haha. I pulled my wiring harness out and the guy who had the car before me chopped it all up. I think I'm gonna get a new obd2a harness and a good jumper harness, and just start from scratch. Opinions?
