i got my hands on a p70 ecu. iv read up on it and its a jdm domina sohc zc v-tec ecu. and i tired to run it on my d16z6 but i get a cel code 21. iv found that jumping a4 to d6 will solve the issue but it didnt. i know the p70 doesnt have a oil pressure sensor, so could that be the issue? its chipped and i thought it would be a good ecu to use. am i wrong? does it work well with a d16z6? any info would be great

If it is chipped try turning off the vtec psi switch on crome. I hear it is a bit buggy though sometimes not switching to the vtec map.

I cant remember 21 and 22 are a bit different. One is more a oil psi/psi switch problem and one is more a solenoid problem. If the ecu stock didn’t come with a pressure switch I don’t think it will throw a code for one but due to the chip and crome it may be looking for one.

I don’t know never laid my hands on a p70 before.

I assume you are on crome?
