Default ecu fried! smoked when i turned on car

i had a p28 and chipped with hondata, i was always gettting a cell 14 so my idle always sucked. i bought a new p28 never been chipped before and i send it to go get chipped and when i turned on the car the ecu started to smoke. what could have cause the problem?

you flipped the TPS and MAP sensor plug around. check your IAT plug as well usually when that burns up the IAT sensor is also melted from my experiance. i've had 2 ecu's come to me with that part burnt before.

Incorrect.
Proper response on: https://honda-tech.com/zerothread/2183785

If you recently performed a motor swap, a common mistake is to burn q31 on the ecu by mixing up the 2 wire plugs on the engine harness!

(Intake air temperature sensor should be a green wire & red/yellow stripe wire. (on most vehicles)


The ecu is probably still usable.
Remove q31 and repair the wiring issue with the vehicle.

yeah i told him in PM that maybe he might've swapped the IACV and IAT wires around too. but he said he didnt touch any of them. from my past experiance the q31 would burn up when either the map/tps or the iacv/iat were swapped around. :shurgs:
