I have a S13 hatch with a dual cam ka in it. I had an SR in my car and when it blew up I decided to pick up a KA for cheap and drop it in for the time being.
I got an obd2 ka and converted it back to obd1 and dropped it in my car. The motor has all emissions deleted off of it and ran ok for about a month then the MAF died. So I put a stock S13 SR maf onto it that I had laying around and when I did that the car just started to dump mass amounts of fuel into the motor and is blowing black smoke out the exhaust at all rpms on or off throttle. I drove it around for a lil bit to see if the problem would correct itself. I drove about 30 miles and killed 1/4 tank of gas with no change to what the car was doing. I returned home and decided to put the old MAF back and nothing changed. Even with the old broken MAF the car was still dumping fuel so I put the SR MAF back on. I am running a Walboro fuel pump and an adjustable fpr. Right now the fuel pressure is set down to about 20lbs at idle. So far I have changed the O2 sensor and needed to replace the ignition coil as it died and the car was getting no spark at all. Still no change in the preformance of the motor.
I am going to try to get another MAF that I can try as well as borrow and ECU from a friend to see if either of those could be the problem. Other than that I'm not really sure what it could be so any help will be appreciated.
Thank You
