I race circle track with my 88 crx and I run in 2nd gear but right before I dive down into the corner I hit the revlimiter a couple of times so I need higher rpms because if I shift into 3rd it'll bog me down so somebody told me to get a ZC ecu but I'am not sure if it'll work on my D15B2 since it came off the dual over head cam motor in Japan so let me know if what you guys think or if there is any other ways that I could do this because I also heard something about using a 86-89 (first Gen.) intergra ecu. Let me know what you think.........

Thanks,
Kyle
