Just download that rom did the patch and swapped over the front/rear o2 sim stuff. Will be trying this after i mow my lawn. THANK YOU!!!!!!

 

I assume your using V7? How did it turn out?

 

Yes Im on v7. Ok so i put it on the car, it works good for the first 30sec or so then the fuel trim spikes to -25 and the car will sputter and die from lack of fuel.

 

Im using aem ugeo if that might change a formula in the patch or something..

 

still no luck. at first it will start strong but then the stft will go from -5 to -25 an the afr will go over 18.4 and the car dies.

 

The EUGO definitely requires a different formula. Have you searched this thread for it?

 

I have posted the UEGO formula either here or in the rear02 logging thread...

 

Ok so i see where to put the 1/mL and bL/mL but where do i put the mL and base equation?

 

anyone?

 

Only 1/mL and bL/mL are needed.

 

Ok thanks. Im going to try this right now!

Oh and in the rom i download to copy the stuff from to my rom, it had the "cold engine close loop afr" at 235.2, isnt that the afr that the ecu is trying to achive for warmup? So shouldnt that be 13.x or 14.x?

 

Yes, 14.7 or maybe a little richer if you want.

 

well i put it thoughs numbers but it still isnt working. The logged afr map is 14.8-15.0 but the actual afr going by the wide band is above 18.4afr

 

what?

 

Exactly what I said. if you go by "AFR map" logged by evoscan it says the afr is 14.8-15.0, but the "external wideband" logged by evoscan is above 18.4 as thats as high as the uego reads.
