I am very new to tuning, have everything needed to do it with a beginners working knowledge of how to do the tuning. Started with an AUJP bin, changed the constants to match engine (383) and injector (30lb) size. Fired the engine up yesterday and did a quick datalog at idle. Haven't been able to drive it yet due to the weather.

Here's my question, my BLM are showing around 112-114, but int is showing in the 130-138 range. So one is showing rich, the other showing lean to my understanding? How can this be? O2 volts mostly in the upper ranges, around 800ish but occassionally will drop down to as low as 100 plus change.

I want to say, tunedperformanc has been helping me, and that help has been invaluable, but thought I would post here too as he is out of pocket for a bit today.

Any tricks to adjusting the fuel? Should it be adjusted in closed or open loop?

One last question, in the VE tables, higher number= more fuel, lower number= less fuel correct?
