hi shiv, i see AFR's on my AEM UEGO WIDEBAND 12:0,12:2 at 7000rpm+++ on a third gear pull is this normal?? i have the 91oct off the shelf map from your site using the xede!
also on a first gear pull they are much leaner ,2nd gear pull less lean,3erd gear pull what i said ,4th and 5th gear pull they go 11:2, 11:4 and 10:8, 11:1 respectively is all this normal??
thanks

 

On the road, 1st and 2nd and 3rd gear pulls may happen to fast to get an accurate AFR reading. So its probably best to test in 4th gear. And those AFR numbers look about right. But a lot will depend on o2 sensor placement and sensor calibration..

thanks shiv, the sensor i placed it on the down pipe.
