fuel problem...

[spardikis]

Hey guys, as a few of you know, i have done an engine swap in my gsi integra. basicly its a 96 vtir bottom end with a 98 type r head running off a chipped obd2 jdm type r ecu.

My problem is that it is over fueling, as alot of black smoke is comming out when i really push the car, and no - its deffinatly not white or grey from oil.

I have used a few parts from my b18b that could be interfearing with its fueling. Saddly the headders are still stock along with the fuel rail and injectors (but will soon be upgradded). the injectors are obd2.

My main concern is the fuel purge tank. It's from the b18b set up. I've only got one vaccume line on it where the b18b engine used two - one on the intake manifold (being used now) and one on the top of the throttle body (not in use - as the itr t.b doesnt have a vacume port)

so i was wondering if the fuel purge tank would make my car over fuel, or would it simply be the chip in the ecu??

Any help is much apreciated....:thumbsup:

the chip on the ECU will control your fuel mapping unless your AFM is giving the wrong signals to your mapping, but i think its the map.

yeah, well i have another standard ecu comming tomorrow, will see how that goes, im just concerned that the fuel purge tank isnt quite hooked up right!!!

thanks limbo

you probably need to custome tune your P28 to suit your engine.

being a hybryd I doubt you will find a stock rom that will unleash its potential and get rid of all yor uproblems.

looking at the hondata unit or power fc, but i just need some good headers first so i dont have to tune twice.
I want all my mechanical upgrades finnished and tuen it lastly.
