Supercharged. What Scangauge Codes to Monitor?

I just installed my ScangaugeII and set up the A/F Ratio, Long and Short Fuel Trims, tranny temp. on the XGauge part. Can anyone tell me what range or level I should look for for Air Fuel Ratio, Short and Long Fuel Trims? I want to make sure that I'm not running lean, etc., with the supercharger and the URD 2.825" pulley.

Here is what I setup in the XGauge:
Short Fuel Trim
TXD RXF RXD MTH
07E00106 044105060000 2808 00C80100FF9C

Long Fuel Trim
TXD RXF RXD MTH
07E00107 044105070000 2808 00C80100FF9C

A/F Ratio
TXD RXF RXD MTH
07DF0124 044145240000 2808 05B900800000



Can anyone suggest any other codes that would be useful or needed with the supercharger.

I would skip using the SG for fuel ratio. Use a real gauge for that like AEM UEGO.

The only thing about the Scangauge, is that the AFR only reads down to 12.0. No lower. I think it doesn't read any higher than 17:1. That part I cannot fully remember.

I wouldn't worry to much about the fuel trims. Rather set the Scangauge to read the AFR from each bank. Driver side and passenger side. It is pretty accurate. Just make sure the refresh rate is set to "Fast".

Whippersnapper is correct though. You should invest in a nice aftermarket wideband gauge/sensor. I am particular to the AEM one. Check out www.Dezod.com.
