I have a p28 ecu chipped by age engineering. The ecu has idle problems because of bad wiring in the car it was last installed in. I was wondering if it would be worth sending it out to have it rewired, and who would be able to do it for me. Thanks

 

If its bad wiring it has nothing to do with the ecu, unless its something internal that's wrong with the ecu. What exactly do you mean by bad wiring?

 

werd......usually theres not much to go wrong soldering a chip in....although its easy to solder 2 terminals together and not even notice due to how close the pins are. did it run like this before the chipping job? maybe its a bad base map?

 

i don't think it was the chipping job that did it. it came like this with the engine i bought off a friend, he said that an animal chewed through the wiring harness in his car and he tried to rewire it himself, when he did that he didn't hook something up right and ever since then it has had a strange idle, so it probably is the base map. I was just wondering cost wise, if it was worth me having it fixed

 

hit up the local junkyard for prices on a wiring harness..... it would be cheaper than having it professionally rewired. not saying you cant do it yourself but it would take time and might be more of a headache if your not patient.

 

the motor wiring harness is fine, it was his car wiring harness that was messed up. I have the motor in a difference car now so the wiring harness is not the issue. The problem was caused by his faulty wiring to his car harness being hooked to the ecu, so now the ecu doesn't let the ca idle correctly.

 

there is no difference between the car wiring and the motor wiring, its all one harness, its just really long and goes from inside the car to the engine. If its been chewed on and the wires were put back together wrong, its either going to have to be re-wired, or another full harness will have to be purchased, but I would assume it will be expensive if you buy it new.

 

yes there is a difference, the engine has its own wiring harness, and it plugs into 3 plugs on each side of the cars wiring harness. Why do I know the harness is fine? because I have another ecu in there right now and I just drove the car 500 miles with no problems. I just wanted a suggestion on where I could send my ecu to be worked on.

 

That doesn't make any sense. The cars wiring harness has different sides, what do you mean by that? I have my entire harness out of the car right now, yes it does plug into certain things that plug into the engine at different points but there aren't two different main harrnesses. Yours must be different than the newer civics.

 

As for a suggestion... Hondata?
