99 civic EX Auto to Manual Swap HELP!!!

[Black4DrEK]

I just did the swap everything is fine except the "IAVC" my car wont idle rite... What do i have to do with the wireing?????

[EmminoDaGreat]

everything should be fine, with iacv, i have never had a problem out of them when i have done auto-manual in civic's. Does it throw a light what?

[Black4DrEK]

um.. ? what kinda re wire did you have to do when u did the swap?

[EmminoDaGreat]

I usually only have to rewire things on the inside of the car auto lock out swith etc. Did you use a 5spd ecu?

[Black4DrEK]

no , thats what i think the prob. is im gettin one in a couple days when i find one.

[GSRteg®]

That would deff be the problem!

no , thats what i think the prob. is im gettin one in a couple days when i find one.

[EmminoDaGreat]

there u go dude. make sure your year model doesnt have an immobilizer, or you will have to get it reflashed to match.

[Black4DrEK]

allrite , what about the map sensor? i got a SKUNK2 mani. and throttle body. idles funky. any answers?

[EmminoDaGreat]

skunk 2 throttle bodys stick... adjust the cable. check tps , check vacuum lines, check iacv, you have no more fitv so it could be that. etc

[Black4DrEK]

allrite thanks yo.. ill post up again if i have more probs. with it.

[iEvo]

yea "EmminoDaGreat" knows his shit. ull deff need the 5speed ECU for it to work right

[d16_turbo]

i just did a auto to manual swap on a 00 civic a couple of weeks ago. i used the auto ecu and it runs fine

[Black4DrEK]

what wireing did u do? if u can help.

[scttydb411]

if you have an ek auto ex or dx 5 speed or manual it uses a 3 wire iacv that needs to be rewired if you are changing to 5 speed ek or any other besides the dx ek chasis and vice versa. if you don't convert to the appropriate iacv wiring/plug it'll idle like crap.

i can get you the info on the repinning. answer this first:
your chassis is a 99 ex auto right? what are you swapping to engine and ecu?

[Black4DrEK]

Yea its a 99 auto ex D16Y8, i changed to 5speed and put the Skunk2 intake mani. and Skunk2 throttle body.

[scttydb411]

did you get a 2 wire iacv? there should be a couple holes on the back of the intake manifold where it goes. you'll need to repin the harness at the ecu.

move b6 to empty b23 and remove b15

[Black4DrEK]

thanks alot . is that it?

[scttydb411]

you'll also need to come up with a 2 wire plug for the iacv. honda uses the same plug on a few other sensors throughout the car so go to pull a part and cut one off...leave yourself plenty of wire to solder it in.

[Black4DrEK]

my plugs are 3 wire plugs.? for the iacv. those wont work?

[scttydb411]

no...5 speed ex uses a 2 wire iacv that you'll have to add if you don't have it and you'll have to do the repin/rewire. i forgot to tell you how to wire in the 2 wire plug didn't i.

you may not get the same wire color on the 2 wire plug unless you specifically cut it from the iacv on a donor car, but you can see the orientation of the wires in relation to the release on the plug.

thanks.
