I must be leaving a lot on the table still. My 357 is 9.7:1 with Vortecs and the 204/207 .447/.459 LT1 cam, long tubes and Eddy performer intake. The truck is 5000lbs, but it feels so slow. And the tune is fairly close according to my datalogs. I've been dissappointed with the power since day 1, especially given the animal the Camaro's 355 was.Quote:

The VE table and AFR table are different, and there's an offset setting that doesn't make a lot of sense to me. I already changed the PE delay to zero, but it goes PE when I don't want it to some times, so I'm gonna change the threshold a bit. My biggest issue is AE, so I've got to get around to adding the MAT. I plan to make it a priority to get my BLMs almost perfect this summer and then dial in the MAT correction in the winter. The stock air cleaner and stove pipe didnt help as much as I'd hoped.Quote:

yeah, same value, slightly different term.Quote:

It can be enabled in CL for a improtu Lean Cruise but I've never tried it yet.

Normally used for open loop but can be used in closed loop if L400D Bit 0 "Open Loop AFR Enabled" is enabled and temperature is greater than L48C6 "Minimum Temperature for Closed Loop" and temperature is less than L48C7 "Maximum Temperature for AFR Lookup in Closed Loop".
With the PE delay gone it can enter any time, best way to keep it out of PE for normal driving is adjust "Minimum TPS for PE " to a much higher level then stock 5.1 %... more like 70%.Quote:

Thanks, Mark. I guess I don't know how to view the BLM historygram, is it a TPV5 thing? I have always used V4. My old computer crapped out so I need to load it fresh anyway, so I'll grab V5 and see if I can figure it out before asking any more stupid questions. haha
I haven't used V4 since the day V5 came out and never looked back!
