The crx I just bought has a b18a and came with two ecu's.
A PM6"crx si" and a PR4"intergra LS". I am currently running the PM6 in the car because it will give me alittle better mpg.

Now I also have a PM8"crx hf" and a PM5"crx dx".

The question I have is that what would happen if I use the PM8. Would I get better mpg but the car would run like half its potential?

Another question is that a PM5 is not set up for mpfi so it wouldnt work...right?

 

why arent u seing the pr4 for the ls motor?try pm7 from dohc zc and see what happens

 

i didnt know pm6 works on a b18.. i guess it would though.. pm5 is a dpfi ecu for d15b2 so no that would not work at all. search for the correct ecu to use.

 

You realize it takes more then just the ECU to increase fuel mileage, correct?

 

Use the PR4 ecu..you have it,use it.

I was going to but he said it is chipped for a turbo.
I am able to still use it but it gets horriable mpg.
