My car has an xs engineering ecu in it which according to xs they discontinued. They told me they had no info on the ecu which was real helpful! Anyway, I was wondering if anyone knew anything about their n/a ecu's. It was purchased in 98-99, so it may have been a while. My car seems to run a little rich and has a 9100 rev limit (not in a hurry to bend valves=8400 shifts) , but other than that I don't know what it is supposed to do for the car. I may go jrsc this summer w/ hondata, but until then I would like to know whats in my car..lol. If anyone can help I would appreciate it.
