055 + Vr4 Ecu Running Issues?

[Kane_GSR]

Hey will the car still run with the 055 wired up and still using the a-spec ECU?

I can either leave the 055 out until I have the chip done but was wondering would it make the car run funny without the chip?

You will find that the 055 will cause you to run somewhere between 25 - 28% lean without having a chip to compensate.
If you are still using your 450's I wouldn't do it.

It also won't idle.

running 510's

off topic: got a 055 for $5

was it your local wrecker?

if you have it chipped to the 510's, don't do it. If you're compensating the 510's with a SAFC or similar, you should be right putting it in. Just set the SAFC back to nothing and go from there. Should be pretty close to matched with the 2 of them in there.

Nice work on the $5 055 lol. Hope it works OK!

Nah it was ebay. If I was to go to a wrecker they woulda charged me more for sure.

I hope it works lol

Ecu isnt chipped. So thinking if it runs leans 25-28% then the extra fuel will rule out the leaness?
