I hate V-Tec!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
ALright so i have a 2000 honda civic ex 2 dr. I bought the car about a year ago with a swapped 97 honda civic lx motor. My problem is that i have the ex ecu in the vehicle, and my motor hits a rev limiter at 5200 rpm. I have asked around about this problem, and my response was to buy a conversion harness off xact dyno, and then purchase a 96 acura integra ls ecu. I have purchase this harness, but now that i am looking for ecu i noticed that the integra ls 96 ecu is obd2. so i am just wondering if my information is incorect, or if any one else has had this problem. Bottom line is that i just need to know the ecu that will be compatible with my harness motor and car, if i even need the harness. And by the way i have searched for a long time, since about last april, so dont tell me to use the search button.

If its an automatic get an automatic '99 - '00 CX/DX/LX (P2E) automatic ECU, plug it in, thats it. If its a manual get a manual '99 - '00 CX/DX/LX (P2E) ECU, preform the IACV fix, shown here in reverse
you will need to obtain a 3 wire IACV plug in this case and add a wire to the engine harness from the 3 wire IACV plug to pin B15 at the ECU.

So what your basically saying is that the 2000 honda civic ex has a 2 wire iacv plug, and what i need to do is move b6 to b23 and take the un used wire from the new three wire plug and plug it into b15 to the ecu

because i do have a 2000 civic cx ecu, and when i did try to use that ecu, i would push the gas in just a little bit, and it was like i had 2 step. my car would hit a limiter at about 1500 rpms, and then with a little more gas i could go all the way to 7000. I tried driving it like that and it was so hesitant i could barley get moving.

Almost, move B23 to B6. Remember the diagram is for converting from a 3 wire to 2 wire IACV, you want to do the opposite.

Alright so today i looked at my iacv to see if i had the three wire plug already. I dont. It looks like theres only two wires. So after i get this plug, will i also have to replace my iacv? and if i do, wont i have to replace my intake manifold because i beleive i have an ex intake manifold, and i read that the lx model and ex model differ slightly.

[QUOTE=v-tecnition;36700415]So after i get this plug, will i also have to replace my iacv?
Yeah, the whole throttlebody actually. The three wire IACV is on the throttlebody unlike the 2 wire version.
Ideally, but you can just block off the holes for the IACV on the back of the IM with piece of aluminum plate and a gasket, you could actually probably get away with just leaving the old IACV bolted to the IM and plug the coolant lines.
Its considerably more than a slight difference. Your ideal solution is probably to run an automatic Y8 IM and TB its setup the same way as a Y7 in terms of the IACV but otherwise its the same as a manual Y8 except the spot for the 2 wire IACV is blocked off.
Heres a picture that will hopefully explain some of it.
