ok i just finshed installing my hmt system.
log manifold, t3 turbo, 2.25 dp to 3 inch exhaust with fmic

d16y7 with d16y8 intake manifold
y7 TB with 3 wire aicv.
450cc dsm injectors
stock

im trying to convert it to a obd1 p06 ecu chipped by dave lee.
when i start up the car with the p06 ecu in the idle jumps to 3k and back down.
im wondering if i messed up somewhere. looking for some help.
i looked on ff-squad to convert the 3 wire to 2 wire, im just missing the plug part but is that really necessary?



some goodies...

 

Man wtf that bitch is almost growing a dick..camo like a motha *****. Anyways change over you iac or else it will idle high and after a sec should start to idle up and down.

 

did you reset the ecu? pull the battery terminal for 15 sec.

also look for vacuum leaks if your idle is surging..

 

are you throwing any codes? is is surgeing from the minute you turn it on? normally if its a IACV problem then it will start normal then once it warms up start to surge, well at least everytime i had that problem it did. i would double check for vacuum leaks or a split tube.

 

sounds like the iacv like they said ^^ i just got my y8 head swap done and have the dx iacv and i tryed using the ex ecu and it went crazy plugged the stock ecu back in and it ran fine.

 

its a vacuum leak some where

 

what year y8 manifold ?


pic ?

 

yep sounds like the problem. my integra used to do that crap to me. reved up to 4000 rpms sometimes on a start up then back down untill in got warm., then stared bouncing but fixed it with a stock iacv

 

i have bugs in my pubic hair

 

alright guys it was the iacv. im in the process of gettting a z6 im and z6 tb. hopefully that should fix my problem.
