Hey guys i recently bought a wide band a/f ratio computer. I have yet to hook it up. Befor i run out and buy jets for my carb i would like to know what i am shooting for as far as a number goes. i do run N2O and i would like to tune it for on the juice so i don't lean out and cause proplems. any info would be nice i know there are guys out there with the lm-1 kit. give me some help.

ok so by smal adjustments what exactly will that be?

Main jets,high speed air bleeds,and power valves.They affect most of your WOT A/F ratio.

Dont worry to much about the idel circuit,set the mixture screws and check to make sure there isnt a stumble.If there is,put in larger squirters.

And of course the smallest adjustments will be fuel pressure and float level (oh,and if you dont have jet extensions,you should get some,they keep it from going lean at lauch do to the fuel slaushing back in the bowl at launch).

And with the nitrous on,use the fuel pressure to fine tune it and only change jets if it needs a larger adjustment.
