Gents,

I spent some time trying to tune the AE TPSdot. I have a lot of work to do, but just playing with the 50 and 200%/sec columns has brought some positive results.

Would any of you be willing to share your plots? I'm more interested in the shape of you graphs and the decel section than I am in the actual numbers you have.

Thanks much,

I dont really like your table.

when I'm tuning Accel-pump, I like a 0 TPSdot column, then the next one right around where my threshold is, so in your case 15.

so my table might look like this on the tpsdot row: -500 -100 -50 0 15 25 50 200 400

this table is focused on you tip-in, so you want a little more resolution at the low end of the scale where you'll be most affected by leanness. You may find 16% adder at 50 tpsdot rate a good value, but since it's interpolating to 0% adder all the way back at the -50 tpsdot rate, you may be hard to tune where it counts the most. YMMV.

Brain,

The TPSdot row has the numbers that came with the base map. I assumed there was a reason. I'll make the changes.

i dont necessarily like their basemap.

Brain,

Do you have suggestions to start with for the negative columns?

keep it at 0% you don't need to tune negative much, youll see if you subtract more than about 10% of fuel it'll be noticable when you lift. it's mainly to help reduce your PW when you lift, just before overrun kicks in, otherwise it'll adversely affect drivabliity.


then once the tip-in's are dialed in, you'll wanna tune EAE which will allow you to keep your AFR perfectly stable even when you maniuplate the pedal up and down.

Brain,

That's one too many columns. I'm going to use -500, -50, 0, and try to tweak the positives next time I get her out of the garage unless there's a reason I need another negative column of Zero.

If I'm going to use Zeroes for the negatives, can I just have -500 and 0?

Thanks,

that's probably sufficient.
