Hey everyone,

So a few months ago I swapped out my d15 for a d16 with a stage 2 cam, p29 pistons, etc. I've been using the P06 ECU since the swap. Today, I got my P28 back from being chipped. I plugged it in and now I'm throwing a CEL 14.

Is the wiring for the IACV different on the p28 that it would be the p06?

When I run the P06, the car runs great with no CELs. However, when I use the P28, it idles REALLY low almost to the point of snubbing out.

Anyone have any ideas?

 

good night bump!

 

good morning bump!

 

I would like to know the answer to this question also....

 

a little bump to go with lunch!

 

i got the same problem.....but even though i change ecu's mines stay on i tried changin the iacv but still comes on i would like to know the answer

 

So I just took the IACV off and cleaned it up.....it was filled with carbon buildup.....however, the problem still stands.

 

I took it out around the block.....It'll keep idling at about 1k....however, unless you mash the pedal to the floor, it'll rev bounce at 1500 and then shoot up from there.

 

i just traded shells with a buddy and i had a eg6 and now have an ek9 hatch and the wiring harness was hacked... i put my poor mans itr in and it ran like ****... i fixed everthing and soldered every wire and im throwing codes 3 + 14 so map sensor and, IACV... my question is on OBD2A at the ECU there is a positive wire, negative wire, and a signal wire for the IACV but only 2 wires at the IACV plug???? WTF where does the other wire go?? lol i really need a wiring diagram for this...

 

yeah on OBD2a its 2 wire IACV and OBD2b is 3 wire. Check www.ff-squad.com for wiring up your shiz.

 

So I guess the problem can be caused by an IACV driver corruption on a chip on the ECU. At least that's what Phearable told me.

 

they may have ****ed up your ECU when chipping it

 

hey i just talk to a buddy of mines and he told me to try tuning the screw on the iacv imma try it and ill update on how that goes
