OK this is so turning into a nightmare. I finally got and installed my obd1 computer thinking this would solve my rev limiter problem at 5000rpm. Now I can only take it to 6800rpm:cry:

Here's what I've done so far for those who don't know. Hopefully you can help. I dropped a 96 b18c motor into my 99 civic ex. I am using my stock wiring harness with a obd1 conversion harness and obd1 p72 ecu. I ran the IAB wires and this works. I here it crack open around 6000rpm. But once I hit 6800rpm I hit a rev limiter. Any ideas. The only weird shit I had to do during the install was use my stock distributor internals and put them in the b18c casing so the wires would plug up. Any ideas... PLEASE HELP!!!
