from what i know...
the C plug on your ecu is for the h22 with auto trans AND traction control...
non-traction control p13's only have a, b and d plugs...
and the traction control h22 lost something like 20 or 40 horses, not sure if it was the ecu or the traction control mechanism that cost the horses though...

dunno about the ecu's, wish i could help more...
and check the block stampings...
don't know that much about the traction control, but i heard they have something on the back of the block that the intermediate shaft goes through? or the axle?
honestly i don't know, hope this helps...

first of all, what tranny are you using- and are you auto or manual?
i've never heard of a 4-plug obd1 ecu. are you sure its an obd1?

as you can see, the obd1 ecu is 3 ports. i don't even know where you'd fit a 4th row of plugs.

The ecu is obd1. I'm using a 2 to 1 conversion harness. The harness has 3 plugs, the ecu has 4. I don't throw any codes. I've taken care of all that. I've been working on this swap for some time now and this is the final piece of the puzzle. Yes, it's a auto trans, but take a look at this:

Since my harness is 3 plug should I be using the type of ecu thats on the left? I have the kind thats on the right.
"My mechanic told me that .75 volts are supposed to go into your ecu. The p-13 ecu is showing 7 volts flat for the idle control valve. How do I correct this? Is my p-13 ecu bad? Can it be fixed? What options do I have?"
I posted the portion in quotes the other day but didn't get much help. Maybe this additional info will help one of you guys better understand what my problem is.

wow- i never saw that before.
if its for aws or traction control, and your car isn't equipped with them, i don't see why you can't just get away with no plugging it in???
perhaps it might throw a code... but i don't see why an "aws feature" would cause the ecu to go to limp mode... but again, im not sure.
i say use what you got now... see if it works. if not, then look into buying the 3-plug ecu.

My ecu does work. I took it out for the first time last night. Shifted great and the vtec kicked in hard. Gave me a big smile 
. The problem is when I'm at a standstill, idling. There were times earlier this week when we took it out for a test drive and the car just died when I was at a stop sign. My mechanic tweaked the idling somehow so it does not die but it is still not idling right. This is also causing me to get off the line slower than I should and we all know how important that first acceleration is. Any thoughts?

Any thoughts?well, if its not throwing a check engine light... its not the ecu or your wiring.
