Ok a friend of mine is having trouble with his gsr swap. he has it in a 93 civic. the car is running rich and the vtec is not engaging. So i ran his codes and it only pulled two codes. #10 IAT, #22 vtec oil pressure valve. his IAT his hooked up and i checked the wire for the pressure valve running to the ECU into D6 (correct me if i am wrong). Still nothing. Also Something else that is odd is it is only throwing thoses two codes but yet the map sensor isn't hooked up. could anybody help out.

ttt it is a P72 ecu

are all the plugs in the right places?

JLefevers

yes everything but the map sensor is hooked up but the only codes it throws are the IAT, and Vtec Pressure Valve. Shoudn't it be throwing a map sensore CEL also?

from my understanding 1 wire goes from the oil pressure switch to the ecu and the other pin on the sensor is grounded. u then want to be sure that u didint get any of the plugs mixed up, a few have the same connector and just because u got 2 mixed up doesnt mean it will throw 2 codes. also w/o the map hooked up it will run like crap

yeah i know without the map sensor it shoud be doing crazy stuff. but it isn't lol thats why i am stumped. it idels fine and runs strong but without vtec .
