Greetings from Suburban Chicago
Hello All;
I've returned to the Honda Civic fold after a 15 plus year absence. I sold my 1981 Civic Sedan in 1989 after 100K miles of pleasurable driving, and this past weekend bought a 1995 Civic ES SE Sedan. Wonderful car.
I would be appreciative if somebody could point me in the right direction regarding ECUs. I'm not looking to play "Speed Racer" in my Civic, but I would like to optimize the engine performance, both in terms of gas mileage and acceleration. On my '81 Civic, I had the distributor recurved and the carb rejeted for improved driveability, and I'd like to do the same with my current ride. In a nutshell, what I would like to eliminate is the slow rampdown of RPM between shifts, and possibly a small advance in ignition timing for improved efficiency, assuming that ignition timing is retarded for NOx reduction. I understand that there would probably be a slight increase in NOx, but if the combustion process is more efficient, there would probably be a slight decrease in HC and CO due to a more efficient burn. I'm NOT looking to play with the variable valve timing. Being as the ECU programming works on a closed loop system, I'm not sure how easy optimization would be. Also, if what I am looking for is possible, I'd sure like to know the impact on emissions testing in Illinois.
For what little research I have done, I'm not sure if the current ECU is reprogrammable, or if I would be looking at an aftermarket ECU.
Thanks in advance,
