i fried 2 ecus tonight, same spot. what am i doing wrong, short to ground somewhere? both times it fried q31. when i put the second ecu in, all i did was plug it in and turned the key to one when it started smoking. at the time i had the usb cable, data cable, and 28 pin ribbon connected to the rtp board.

 

ummmm is that the IAT piece? i had that problem and the plugs on my IAT and IACV were switched around on the engine harness

edit: nvm, its q21 i burnt out

 

is there a diagram somewhere to show which pins on the harness are what? i thought hondata had one, but i cannot find one on there website

 

hondahookups.com has all the service manuals if thats what ur asking for


i have it on my laptop but not on this comp

 

yep ur plugs are switched! look in the manual...if u got one...

 

which plugs?

can you see them in this pic?

thanks, didnt even think to search using the pin number

 

is this the pvc valve?

 

u need to go out to ur car and look at the engine harness and tell us the colors of the wiring, that will determine if anything is switched around
