Ok heres the situation.

When i put a chipped obd1 ecu and jumper harness in my Teg its goes into limp mode and wont rev past 2500.

I swap chips and it runs fine. I swap back to the original obd2b ecu and its fine.

So i take the first chip put it back in the ecu and run it on a obd1 car and it runs fine just high idle, but it revs way past 2500.

My question is there a wire I need to switch around? I know obd2b civics need to swap IACV wires, but Integras should be plug and play right?

also will i need to switch to a obd1 dizzy?

 

You don't need to switch anything. It's a direct plug and play.
You also do not need an obd1 distributor.


What motor is this? and what basemap are you using?

 

its a b18b1. its on chrome i believe.. all stock motor with 8psi

it works in my obd1 civic but not my obd2b teg

 

You mean Crome?

No CEL or anything?

 

O my bad Crome. Ill have to check the CEL in the morning.. Do i check CELs in both cars? jss to see what comes up?

Thanks for trying to help me out.

 

The question is there even a CEL visible? If so in which car does the CEL come up in.

 

its throwing code 6 and 36 in my obd1 civic.. but it will rev all the way no hesitation. i have to go to the other house and check the integra

hrmmm nothing looks like the reason it wont rev past 2500 in the my obd2b teg... it wierd cuz ill swap chips and it revs fine.. argghhhhhhh

 

The thing is you don't even have a JDM ecu so code 36 shouldn't even be there. Where did you buy the conversion harness?

 

It's the code base he's using that will present code 36. It has nothing to do with the ECU.

 

Must be the JDM p30 base then

 

it was throwing code 7 not 6... here is a link
My ecu codes

 

Im just gonna swap engine and interior harnesses from a obd1 Integra I just got.. Ive done it before took me about 3 days..
