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

typical bullshit... Try Crome before you give up completely on Rom Editors.

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

Chrome is meant for OBD1 Ecus

Re: uberdata afr not stable
 

I don't understand. How does it "engage really hard" but you don't feel a gain in power?

really rough,and loud but the car dont launch, like it use to

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.

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.

11.9 is way too rich for VTEC N/A crossover. Try 13.3

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
