TLIQ set to high number stops defuel if tuned correctly. So does a high number in the base torque. But if tuned wrong, flare will be present.

yes.. i normallyon base torque max out 2200rpm to 4000rpm annd form 80mm throttle to 100mm

TLIQ same rpm i put 101mm3 in rows 554-738. that is what i have found to work the best

ECM doent read anything above 100mm3

dont knjow the 100mm3 limit works for me..
a stock turbo LB7 did 569hp
a BD turbo stock cp3 did 607hp


none of my tunes command more then 100mm3... just saying that keeping the "commanded 100mm3" limit has been working for me and doing me well

Ok, I'm confused.... I tried playing with the defuel table(s) at one time. The way I understood it, the Tq Limit tables indicate how much fuel will be injected when a specific cell is specified based on SAE.RPM and DMAX_TRQ values. When I tried increasing the values to make for what seemed like it would result in zero defuel, what actually happened was when it shifted, it actually dumped more fuel in than I was expecting... Since the option to remove defuel came out in the TCM, my transmission has shifted better than it ever did with defuel.

What is the value in the referenced cell during the shift? Many times a reference to the 400+ torque cell is made because of the calculations made as a percentage just before a shift. TLIQ has everything to do with this calculation. IIRC The calculation is described in this table. And, what could appear as more fuel " that calculated mm3 as reported thing " could actually be a drop in volumetric efficiency during that shift resulting in black smoke. That is if the smoke is a signal to you as more fuel. Just assuming here since a log is not present.

I don't remember as it's been a long time since I played with it... There was no smoke, I was logging it at the time, and on the shift, the injected quantity shot up and made the shifts really stupid from the extra fuel.

Oh, I see. I bet it's that reported thing if that's the case. Unless you have an lly or lbz or lmm. lol

Hmm i have to fix this, i tried out the McRat tune and let it loose, itl de-fuel so hard in between shifts you will eat the dash :eek:

Must fix.

Yours may be due to a torque limit hit. Check your max torque parameters. Can't remember the table number, I'll have to get back to you when I get efi working again lol.


Pm sent.
