I searched around and found out that most if not all the performance ECU's are for the OBD1's on Preludes. I also found out that the OBD2 ECU on the 5th gen preludes will soon learn if you installed any aftermarket parts and will adjust it's air/fuel to compensate so if you installed any parts, it is useless to get any gains. I read that you can purchase a conversion harness so you can use the OBD1 ECU's. Does anyone have a OBD1 ECU on their 5th gen preludes?

well the simplest way to solve that problem, is just pull your ecu fuse out and put it back in every 100+ miles, by doing so you clear the "Memory" so it has to relearn. bad part is that you have to enter the radio security code, presets, etc.
I have seen a write up on NTPOG on how you could turn the memory on your ECU on or off by a flick of a switch. Ive considered to do this myself but im not sure how well it works. Has anyone else on this forum tried that tutorial yet? the link is http://wwww.ntpog/mods/index.shtml
As for conversion harness's for OBDI>OBDII most 5th gen owners i know solve the problem with that method.
btw anyone know anything on that new blitz R-vit? i took a glance at the article in the new import tuner, would that solve the 5th gen OBDII problem?
