I put a d15b in place of my AUTO d16y7. -I have it running off my stock y7 ecu as NOONE makes a obd2b-obd1 conversion harness for AUTOMATIC cars. -The engine runs but after a minute or two sounds as though it is about to die. What could this be? (map sensor?) -Would a y8 ecu work better? -Will the y7 or y8 ecu harm my motor? -Can I do anything to the motor to make it run off a y8 ecu? Timing etc? I'm a longtime member of clubcivic.com and 780tuners.com but this is my first time here. You all seem to know alot so I thought I'd drop by and get help / give help! This is a tricky situation. My shop installed the motor cause they're all noobs..I was told tog et a d15 ecu, which I did.. (auto too).. and know they wont put it inc ause i need a conversion harness which was never part of the deal.. They charged me more and wont give me the prmised 90 day warranty.. HELP ME! lol.
