I just got my CRX running this weekend with the Hack on a B16A motor. The problem that I am having is at idle my A/F Guage barely register on the lean side. Since I am running the B16A PR3, I am using two o2 and the guage is hooked to the original o2 wire at the ECU. Idle is a little ruff, 600-720 est. My cor setting is at -37% and goes up to -35% for 7k-8.5k. Am I getting the correct readings?? I mean the ecu is reading teo o2.......Oh yeah when the car is on the highway it also barely registers while I am crusing but it's running good. I've tried richen it a little but it won't idle. Once you give it gas it immediately jumps to green so I know it is working. I am just not sure if those are same readings other B16A owners are seeing in their cars. My BTM is set at 0.5/lb.
I tried searching the archives for info but turned up nothing so here I am.

 

My A/F gauge did the same thing. Even after SFP tuned the Hondata, my A/F would consistently relay some weird reading which were inconsistent with what the car was doing..

 

So I take it that is normal when you have two o2's. I am glad that I am not alone. Damn so freeking hard to type with one hand. Almost sliced my fingers off this weekend.

Anyone else?? How about an RPM fluctuation when the car is stopped and you try to hold the rpm at oh say 3k and it goes up and down like your IAC is bad??

 

those A/F gauges arent really reliable. they are more for an overall indicator if something is really rich or really lean. mine bounces like that, too, when the car is stopped. its the way the O2 works, its constantly going rich/lean trying to hit that magic A/F when in closed loop. if you have access, put it on a wideband. thats the best way to see what your A/F are.

 

wideband only $350
