I have a 2002 ls1 with the t56 6 speed. When I tried changing table b3303 (fuel cut-off limiters in gear) in 2nd and 3rd gear to be at 3k and 4k it didn't work. However when I selected all cells/all gears and set them to 3000 that worked.

Is this table b3303 for an auto only? I set my axle ratio to 4.10 (table h103) and my speedometer seems accurate.

I can see that table being for auto trans...

How would the PCM determine which manual trans gear was selected (it might be able to if it knew the manual trans gear ratios)...?

If you changed all the cells, then this would mean that a specific one of them is used as the rev limiter for all manual trans gears... or rather, maybe it's the Not-In-Gear cell.

I thought about the Not-In-Gear cell thing too, I'll try it tomorrow.

The LS1 PCM doesn't keep track of the gear on a manual trans. Well, it does for the CAGS, but it's all assumed, not measured.

did a little more testing, it appears the "not in gear" cells are the only ones that effect the rev limiter on my t56
