What should BLMs be doing going down the road? I have 128-130 at idle, but when I'm accelerating, what should the BLMs look like. Should I be around 128 in all cells?? Thanks.
Interesting. That's what I thought, but wanted to confirm. The closer I get to boost, the higher my BLMs are going. I was going to get a new chip anyways, but I want to make sure I'm tuned right first.

128 just means the ecm isn't making any corrections to the fuel. I doubt anyone has 128s in all the cells. The cells just allow for quicker BLM corrections, as load conditions change. 128s are a nice target, but they will vary, from time to time, as gas and weather conditions change.
Hi Doc, Just curious why you say you doubt anyone would have 128 across the board. I have 128 in all the cells in both open and closed loop, and I thought this was good to have. I do have a slight hesitation while idling and the car is revved, just can't seem to find the culprit. It can hide all it wants, I will find it. :headbang:
Probably because 128 implies the ecm never has to make a correction to fueling, yet, changing conditions should necessitate the ecm making some corrections at various times.
it got alot easier in OBDII cars where you have a short term and long term fuel trim- you have 0, +, and - if your in the plus your adding a percentage of fuel, in the minus your pulling fuel out. a good running car will bounce around -5 to +5 in the short term usualy and be -1 to +1% in the long term
sooooo much easier
