I have searched and searched but very few details.

I have an 89 CRX.
Swapped a ZC and SI tranny into it.
The ECU is PR4 and it runs too damn rich.
I have had it for about 4 months and didnt really think it would bother me.
But now it keeps bugging me that I only get tops about 300km to a full tank.

Any suggestions on different ECU's?
Chipped or not.

Stories and thoughts/suggestions would be appreciated.
Thanks.

PR4 ecu is for a LS integra...get the correct ecu and you shouldnt have any problems

 

This PR4 I got out of a stock plain Jane 1990 Integra.
Non LS.

Do you have any suggestions?

What would the best ECU to get chipped without sacrificing the rev limiter?
What would be the ideal redline?

I know the JDM ZC ECU would be great but the cost and resources to get one is out of my reach.

If any ZC CRX owners can share some experiences it would be great to hear some other options.

What does everyoneget to the full tank anyways? - Roughly 30L

 

88-89 Integra PG7 manual transmission ECU works well

 

Can you get the PR4 chipped to the ZC ECU specs?
If so how costly would it be?

Im in Canada.
