How do I get read off the pops on deacceleration ?

The F-tables do not work at low throttle openings.
You have to go for the L-Tables.
You can also raise ETV values at closed throttle slightly.
It will reduce engine braking a little, but might help with these popping issues.
Prost.

So by increasing the values on the L table in TuneECU you're essentially adjusting air to fuel ratios at lower throttle settings? So what do the numbers in the table's cells represent?

Thank you!! what do i have to change in the L table?

The map I have from the old Tuneboy file shows the very bottom the entire row is changed to 610, and then 6th white column from left from bottom going up the next 4 cells up the numbers are increased by 10%. The 7th thru 12th columns the next 4 cells up are increased by 15%. The 13th column has 4 cells fom bottom increased by 10%. The 14th column has only 3 cells from bottom increased by 10%, and the 15th column only 2 cells increased by 10%.. Also going back to the 7th thru 9th column rows 6, 7, and 8 are increased by 10%. Columns 9, 10, and 11 cells on row 6 are increased by 10%. There is also an accompaning note that says if that doesn't get the decel pop eliminated to go back and add 5% more to those areas proportionately. That should be adding more fuel on the last 6% of throttle.

When I copied that from L1 and pasted into L2, and L3 then downloaded to my 05 Rocket the decel pop was pretty much gone for several months, but did come back somewhat over time, reloading the file again cured it again. Sorry I can't scan the image for you.

Thank you very much. But I really don't know how the % is done.

Thank you. I am sorry but maybe we are looking at deferent L table. . the % is only on the graphic mode .

The Tuneboy L tables had only 3 digits in each cell, so it was simply take that number and multiply it by 1.1 or 1.15 and insert that value back into the table (or scroll the number) at the required location. With TuneECU you'll need better information on what cells need modified and by how much from someone like Penner or try the TuneECU forum. The L tables are not the same format between Tuneboy and TuneECU, so I can't give you anymore guidance than get hold of a tuner and you can get it sorted.

Tune ECU shows you the switchpoint between L and F tables. With the new Rockets it is pretty low at about 4%TPS. Up to 4% throttle it is just the signnal from the MAP-sensor. There is also a transition area where it is interpolated between the two.
If you want too enrich the mixture at closed throttle deceleration, go for the L-tables. Connect Tune-ECU and have a look at the MAP-signal at idle. Then add 20% to all the L-columns below that value.

You might consider doing a tutorial on Youtube to show how you accomplish that and then post it here or the TuneECU thread.
