I played around with the tables a bit, I'm going to run this tomorrow. Logs to follow.

-lamfa smoothed out, good and rich at 90% to ramp up, and very rich at WOT to redline.
-ldrxn tapered down slightly after 5k (I'm only logging to just over 6k and small turbo)
-zklamfaw_0_A table modified to 80%

whatcha think?

I would increase the 1000 rpm row in the last two columns to something like .95, but otherwise looks good to me.  Log it!

Horray!  I think we finally have LAMFA doing what we want it to do.  I still suggest that you modify the 1000 rpm row of lamfa to be something like .95.  Too rich too soon.

Richening when you look at the throttle is not what you want it to do.

What my fine friend here is trying to say is that we need to bring in LAMFA more smoothly.

Let's modify the LAMFA RPM axis to include a 2000 rpm row so we can better control the request during spool.

Then, let's use these values
1000, 1
2000, .84
3000, .82
.....
6500, .82

Then, we should raise TABGBTS (threshold for BTS enrichment) to 1000 and I think our fueling will be close to done.

I can get TABGBTS in the xdf if it is not already.

I'd also maybe bump ZK back up a *touch*... filtering isn't bad considering how bad the resolution of LAMFA is.

I think i have it defined correctly but verification would be nice.

I made some minor adjustments, including the lamfa column change (add 2000rpm row) and some ramp-up in the top of the lamfa table, and zklamfaw_0_A set to 60% across the board.

Nice! Can anyone confirm this location?   Grin

60% is still to much... LAMFA is still lumpy
Also LAMFA isn't exactly smooth.. thats a weird dropoff you got going there..

Finally, BTS still triggering

oops. back to the drawing board.  Embarrassed

-I ditched the 90% adjustments for now, they're back to stock 14.7

-Completely re-arranged Lamfa's rpm axis values for more adjustment between 1k and 3500 (where I need it)

-Finally, adjusted the last  column lamfa values while looking at the graph

Here's a shot of the new lamfa profile

Log later today hopefully
