have been running the old b16 computer and just got my itr computer today. put it in and it is pulling harder but it seams to lean out on my a/f guage after it hits vtec (set at 5400 vafc) any suggestions. I was thinkin that I might need to upgrade the fuel pump to gsr or itr. also I was wondering what all of you are are setting you vafc hi and low throttles at. Want to get this settled before wednesday so I can run her at the track-thanks

 

also does anyone know if the timing belt cover on the b16 is the same as the itr. didnt have a cover so ripped the cover of my b16a2 and used that to time it.

 

I belive they are the same. I don't think the GS-R's aren't cause they are alittle bit taller motors then the B16 so I'm not 100% sure but I believe it may fit.

 

its always good to upgrade I did mine myself dropped the whole tank and all. upgrade it anyway If your juicin or boostin.

 

The pump may be the problem. Also the vtec unmatched values on the vafc must be changed as well. You cannot just move vtec to a different point and expect everything to be smooth. Vtec will be at a different point, but it wiill not be running the correct fuel maps needed to run properly. Without a good tuner, the vafc is just good for its visuals.

 

I had the same problem I put in a holly pump and it solved that problem.

 

ok thanks guys. think I will change the fuel pump
