uberdata afr not stable
I am currently running uberdata 1.70 on my b16 with RC 750cc injectors walboro 255lph pump, and fuel pressure at 42 psi at 10.5 psi of boost. I just did a long run where everything was perfect AFR was around 11.50 to 12.20 all the way to redline, so I say ok thats it should be good to go now... turn the car off for 10 minutes, and did another run now I am rich as hell 9.50 to 10.40 what the ----? should I just get that new hondata or what?
edit: I am using zeitronix and uberdata datalogging, its always cold here so its not temperature change, also I had to uncheck PA sensor to idle stable

Re: uberdata afr not stable
will chrome work on obd1 ecu's?
I thought I learn enough about uberdata to start helping others but I guess if it runs like ---- on my car I cant recomend it
also at vtec engagement it engage really hard,but no noticeable gain in power. afr is at 11.90 is that too rich or do I need to make it richer, for a smoother engagement

Re: uberdata afr not stable
Are you actually using the Zeitronix datalogging software or Uberdata because there is going to be an inaccurate reading for the non-linear reading of the Zeitronix on the Uberdata Datalogging. I've just been using the Zeitronix Program and it works good.

Re: uberdata afr not stable
let me see the uberdata map, post it.
Uberdata and Crome work just fine. They have been proven time and time again. All 3 Hondata/Uberdata/Crome operate by modifying stock ECU code, changing the interface won't cure your problem.
like i said, post the map, ill take a looksie and see if theres anything obviously wrong. From there it could jsut be a retune time.

Re: uberdata afr not stable
went for a tuning run with some help, everything in the afr, is 11.50-12.00 which I think is very safe and perfect, but I threw a CEL on the way back I hit 10.5 psi, but the Cel wont go away even if I reset the ecu and swap chips, hope the ecu aint burnt. I will do a code check tomarrow, but other than that I am satistfied with these AFR 11.90 in boost high and low maps, 16-17 at idle , 14-13 at part throttle, egt at part throttle is 1600*F. and average 1200*F whats a safe egt? at full boost I see 1400*F
