My setup is a aps st kit with walbro 255 and 600cc dworks. The car will start and idle but keeps a 10.0 to 10.6 a/f. It seems like no matter how much fuel my tuner takes out it still runs the same a/f. Its like it has no response. The utec is set to map 1 while tuning on map 1.

 

maybe your wideband is not reading correctly ?

 

he thinks he may have found it. something to do with switch 9 controls map 1 or something.

The wb is reading correctly bc you can smell and see the fuel.

 

i see g/l with everything . give sharif a call or pm he'll help you out with it very friendly guy .

 

When I tried to tune my utec with some 600cc I was told just to adjust the 0 percent column and had the TN fuel map from XS site. No mater what I did it ran rich so I towed it to the tuner and he adjusted all the columns and almost kept all my orginal 0 percent column. And it idled great. I thought it was the car but it just took a good tuner. And what WB are you using? I recommend the tuner pro because it's great for logging with utec.

 

Make sure that the switch on the UTEC itself is set to 0, while the map switch is set to 1.

 

Its weird that switch one does not operate map one but that was the problem.
