Lb7 rev limit, and fueling help please

[Jstewy21]

I have built a DSP5 tune, in tunes 1 and 2 it will rev to 4500. But in 3 and above it will not, I have the base torque, throttle inj., and tliq the same in all the tunes... why is it not revving out in the higher tunes? Also I have been reading about the relation of these fuel tables to each other, what does the relationship have to do with? Just transmission, or are there other areas that are affected? Thanks for any help.

The tune file and also logs of it happening.

Does it hit a limiter / cut off or just shift early?

[Jstewy21]

Ok thanks, it hits a limiter of some kind. Just like it would for the stock fueling tables, position 1 and 2 will hit 4500 in p/n just fine. 3-5 won't go above 3500 just like stock. Haven't changed the shift points yet so the shift patterns are the same.

These are the two files I'm using right now, the second (skyler lb7) is the one where I got a little "creative" with the fueling tables and torque tables. Help is greatly appeciated.

I wonder if there is an issue on EFILIVE's end as I don't see the max injected fuel quantity table anymore in teh DSP5 tables. I checked and it is there in a DSP2 file, but not in a DSP5. I could have swore I made changes to that table in teh last LB7 I did a awhile back with a DSP5(I don't do many DSP5's for LB7's, mostly DSP2). For the heck of it, try going into your limp home tables and raise up the engine protection fuel limits to see if maybe it is going into a ghost limp mode or something.

I'll look into that, hopefully someone can see a problem. It doesn't make sense to me that it isn't consistent through all the tunes. Only difference between tunes is timing and pulse width.
