ok-i can get an integra 89 ecu-but are you sure that it will work with a z6 head{vtec}i dont really want to use a vtec controller i would rather have every thing as close to stock as possible.just to catch every body up:i have a 90 crx si.i am putting a z6 vtec head from a 95 ex on the crx.at this point i dont even want to havethe vtec controller as an option.as many combinations that you guys have used,and the parts you did it with would be MUCH appriectiated-also anyone that has ever used those integra ecu'slet me know how they worked.thanks guys.
