Put an h22a1 from a 93 sivtec (with its ecu) in a 96 prelude S, I’ve had to wire a bunch of **** obviously, keeping it short she runs and drives and when cold has no issues with fueling or ignition timing but once temp gauge shows operating temp hesitates at anything over very light throttle. Babying the throttle it’ll go thru the powerband smooth and perfect but doesn’t know what to do when there’s extra air comin in. No CELs, had code 43 after I had wired up all the individual item codes and fixed that by replacing the Bosch o2 with a denso. The 93 lude had one 3-pin connector (MAP or TPS) on the engine harness and one that was part of the body harness. On the 96 there was no 3-pin on the firewall and the old engine harness for the f had both on the engine harness so I wired the map to the jumper harness. That’s about the best I can think of for info that makes this different than other’s problems, lemme know what ya got

edit: **** I’ve wired to the jumper harness bc obd1 in obd2 chassis: ckp, cyp, tdc, knock sensor, map sensor, o2 sensor, vtec ****

Problems I’ve had with the swap is since I first started the motor (by wiring cyp/kp and tdc) and pulled the initial codes it has hesitated the same, and it feels like wiring the MAP O2 and knock signals did nothing but fix idle. Wire tps straight to the jumper harness?
