have an 04 EVO that has had a EXED with Smart in my car for over a year. I had no problems with the exde till I had a 2.3 stroker motor installed. The EXDE was disconnected when the motor was installed because it was not working.

Well I went to tuning Technologies to get tuned yesterday and the EXDE was not operating properly. The light on the exde was staying soild green but the Exde could not get the car to ideal correctly. The ideal would go from 1k-2k rpm for no reason and than stall. The car would sometimes back fire. The car ran like crap with the exde

TT tried 3 different EXDEs. Same problem. TT installed brand new wiring harness, same issue with the ideal. TT tried bypassing the smart, same problem.

The car runs perfect with only the ECU at 12psi. Ideals great no backfires nothing. What could be the problem here.

Did you get a different cam or crank sensor with your 2.3L install?

Nope

Did you change any sensors what so ever with your 2.3L buildup? Are you using a ECU extension harness like the fields one with the Xede?

I didnt install or build the motor.. RRE did everything. I dont believe any sensors were replaced. Im not sure what the ecu extention harness is. i connect the 2 harness to the xede and remove the harness on the far right on the ecu, plug the xede harness into the ecu and than plug the factory harness into the XEDE. If want you can pm ur number to me and discuss this overe the phone

Have you asked RRE about this?

No I haven't. Why would it matter car runs fine off the ECU. The only abnormal code im throwing is the EGR, however all my EGR is connected.

because the Xede processes the sensors, changes them, and sends them to the ECU. Thats how piggybacks work. If the xede was programmed for stock 2.0L sensors and you have different sensors or something else is changed from a normal 2.0L data feed to the ECU, then I could see a problem. Espically since you have tried a bunch of Xedes and harness's with same effect.

if this was the case my ecu would have been changed as well
