TPS VE for idle fueling ?

[3fingas]

Is it possible to use TPS VE solely for idle fueling? I am having difficulty leaning out my idle cells in the main VE and wanted to try to tune fueling for idle in A0007. Must I populate the entire table for this or just the cells I plan on using within in the set parameters? Best lean idle is at 12.3 on e85.

All PE is set to lambda 1.01 through 3600/ 0.86 through 8000
B3647 set to 1.01
No IAC
No NB 02's ( LC1's on both banks)
Idle spark 17-26*
Cam 250/260 .671"
Idle VE at 95kpa

Thanks in advance for any input.

Got it! No worries, Thanks

You only need to populate TPS VE table only up to the enable threshold.

BTW: regarding your PE: what happens if you stomp the throttle pedal below 3600 rpm (your engine is going to be too lean).

Hey Joe,

PE will be tuned before I get into the throttle, just trying to get it to idle so I could drive onto the dyno. LOL Problem was the ground on the map weatherpak pin was bent. Now at 70-75kpa at idle. I was just lucky as the connector was the first thing I went to look at.

I would like to run solely on A0007 but the entire map table has to be redone. A lot has been modified to the motor and most of the table is fat by 30-40%. So for now I was just trying to use TPSVE for the idle cells. Big cam'd race motors don't like to idle at 600 rpm. LOL

Yes, that's a pretty big cam 250/260 @ .050"

what is the LSA and the advance...?

Its on a 114 solid roller 376 LS3, 13:1 w 2 stages of n20 on e85.
