I plugged in Kenji's chipped P28, and his conversion harness today.

00 JDM ITR, 2000 Si harness

I knew it was going to throw a code or two because of the vtec pressure switch, but the problem is we can't even pull codes from it. The CEL is on!

The idle fluctuates for about 15 seconds (up, down, up, down, up, down) then it will calm to about 1300. It does this everytime I let it go to an idle.

My questions are:

-Would not having a vtec pressure switch be causing all this?
-Is there an OBD1 component that I need to include somewhere when converting OBD2 - OBD1?

I wasn't getting any CEL's before when I was running the CTR ecu.

HELP! thanks

'00 si is obd-2...p28 is obd-1 have to have a obd-1 harness for a obd-1 ECU. I could be wrong on this

 

OBD1 vehicles have thaat thing under the TB. Maybe that is it?

 

what kind of car do you have? is that an engine swap w/ JDM ITR Engine? I thought jdm are not obd2

http://hondata.com/techecuid.html has some information there

 

Try this. Unplug your EVAP purge solenoid near the firewall.

 

Yes, I have a conversion harness. (of course!)

Anyways, I fixed the idle problem. I put a piece of duct tape over this hole, for the time being:



I also checked the code, which is 22. I believe it has something to do with the vtec pressure switch, since I don't have that yet.

 

You need to also remeber that this is more of a racing ecu, Not designed for emissions or Perfect drivabilty! This ecu is designed to make power!

have fun! eric

 

gotcha! I'm just glad I didn't have any problems with kenji's stuff.

Kenji is the man!

 

Kenji's products rock!

What's more, his service is the best, period.

 

Thanks for the compliments guys.

If you have any more questions feel free to ask me. Thanks.
