ok, i think, i´m lost...off idle stumble $8D
Hi all
for reference, my last post...https://www.thirdgen.org/forums/diy-...ip-tuners.html
i still have the problem when take off...i increased the AE MAP tables, AE TPS also a bit, car runs fine, when changing throttle under higher speeds, no problem..
with my WB02 installed, i have the following..when take off, AFR goes down from 14.4 (idle) to about 13, car begins to move, a bit more throttle, AFR goes up to 15, bog occurs, than goes down to 14.x ...
how can i get rid of this bog? it occurs, when the throttle is changed rather slowly, i would say, when you increase the throttle from lets say about 5% to 15%
or are my VE tables that off? hard to believe.....
hope you help me, i hate this bogging...
a screenshot of my AE tables is attached
thank you

It kind of sounds like VE. Datalog it, look at INT. If it has to go a long way to reach stoich, your VE is off. Play with it to see if you can get it to start removing fuel in the same situation, you'll be glad you when it does.
When you say you increased AE a bit, do you mean anything less than doubling it? MAP AE is the slightly slower term like in this situation. Give it heck with the Ctemp multiplier, and see what happens.

I'm weird, but I tuned for that in the VE tables
Just watch your map readings when it starts to lean out, and add fuel in those tables
Then double check your spark table, perhaps a few extra degrees in that same area could help smooth things out

Hi
i will take a close look in that area, i will drive with the computer tomorrow
i increased AE delta TPS mult vs delta TPS about 50%....
just made a test drive, altered a few AE tables, i got so rich under WOT (AFR under 11) so that i got a rich cut out....but still have the initial bog...
i think, the bog occurs, when AE is decayed and swithced to the normal VE table..and i have to find where this transition occurs..
thank you..
