I was wondering if anyone in here is using an OBD1 GSR ECU with a B20VTEC? Any problems ? Running Lean? Sputtering? Thanks.

 

Well my friends CRVTEC is composed of B20B block, GSR head (Portflow), JE 12.0:1 pistons, stock rods, CTR cams, sprockets, RC 310cc injectors, and a Type R ECU. He still needs a VAFC to richen up his entire band which is perfect at 11% on top end. Oh and yea it runs really lean with the VAFC zeroed out. If you have a turbo then i definately think you'll be wanting more fuel. I would go with a chipped P28 ECU and Hondata stage 4b. That's what my other friend is running on his GSR turbo coupe. Oh and by the way on 22x9.5x13 M&H Racemasters my friends CRVTEC in his 99 hatch with just no back and passenger seat ran 12.8@106. The GSR turbo on 24.5x9x13 MT slicks ran 12.5@112 on 10 psi with full interior. Richen ur **** up with ur turbo and you'll get hella more power!!!!!!

 

*scratching head*
BG Boost - the only thing i wonder about is the knock sensor...does your b20vtec have one? plus the motor might need a little more fuel than what the gsr ecu can give.
it might be easier to just get a p28 with a mugen chip, at least i have heard those run the b20vtec pretty good

 

I have a crvtec setup running a obd1 gsr ecu. My car lacks top end really bad. I have the fuel regulator set at 45 psi. I dont know what to do. I hooked up a skunk2 chipped p28 ecu and my car detonated like a motha *****. My air fuel gauge was burried rich too. I have only ran my car in the 1/8 mile and its best time was a 9.1 at 77mph. The top end is just not there, somebody please fix my problem!!!!!!!!

 

are you running a 2.5in exhaust?

(sorry - this is a stock question for those with B20's complaining about their top end...)

t..

 

I have a complete apexi dunk exhaust w/ the b pipe

 

well i know that ImportBuilders use the P28 chipped Mugen ECU along with hondata tuning. try that.
