Ok i switch my coupe down to obd1 because i plan on boosting it but when i hooked up the ecu with the harness and i got the honda chipping kit its throwing a code 17 (vehicle speed senor) and a code 41( oxygen sensor heater) but my tach and all my gauges are working fine..can some please help me out

rick_rabies

no codes when you had the obd1 ecu in?
some obd1 ecus dont read a 2nd o2 sensor.
and it could be the chip you have in the ecu. take out the chip and then check codes.

rhd98civic

No its a completly stock car i just took the stock obd2 ecu out and plugged the obd1 ecu in with the correct harness but i took the chip out like you said and i still get the same codes..

What ECU? What chip are you using (hondata, crome, uber??)

rick_rabies

it could be that ecu. try a dif obd1 ecu. did you unplug any sensors or anything? try pushing them together making sure they are still connected....
plus your obd1-2 adapter could be wak too....some wires in wrong places...it happnes

rhd98civic

its a p28 and the chip isent programmed yet but i was gonna run chrome on it

rhd98civic

Yeah i dont have another obd1 ecu on me at the moment i might have to go get another one but yes i unplugged both the sensors and check them to make sure they looked in good working order and plugged them back...

rick_rabies

where did you get your adapter from? if another ecu does the same thing i would point at the adapter and blame it.

rhd98civic

ummm....yeah i got one off of ebay its the red block one from xactdyno is what is says on the connetor

rick_rabies

do any of your friends have one? try a dif one. process of elimination

rhd98civic

Alright will do im gonna go snag me up another ecu or 2 haha but no one i know of has a honda with the adapter, I might have to order another one just a diffrent kind..?

rick_rabies

rhd98civic
