Has anyone tried changing the LEDs on the Adaptronic face plate to show the Autotune modes? I have it mounted for now where I could see them while driving. The manual recommends setting up LEDs to show what tuning mode it is in but I do not want to give up any of the outputs for the LEDs. I am wondering if anyone has tried it with the face plate LEDs and found it useful.

Personally, I never saw a need for the lights when autotuning. Just drive (semi) normally, trying to spend as much time on the 500 RPM increments and let it do its thing. It will get you in the ballpark. Also, be sure to reference the "gauges" window on the WARI and compare to your tach so you know what "on" the 500 really is. Mine is off anywhere from 100 to 300 RPM depending on where I am on the tach. If it's off, you think you are holding on the 2500, 4000 mark, etc and you are off of it enough that it won't even autotune.

That said, I spent a couple hours Saturday and Sunday doing logs and hand tuning. I'm pretty lucky as I live in the country and there is a pretty vacant stretch of highway a mile from my house.

I would do pulls in 3rd or 4th and only concentrate on holding 80, 100, 120, 140 and 160 kPa from 2500 to redline, come back, run through Meagalog Viewer, jot down AFR's and adjust the map in open loop. I did six sessions and the car is pretty well tuned now. Nice even AFR's.

It's really tough to autotune anything between 100kPa and whatever pressures that are less than WOT pressures for your car in the 4,000+ as it never holds long enough in a cell to auto tune. If you run with the MAP trace on, you will see how many of those cells that the ECU never sees, let alone see long enough to autotune.

John, what are your settings for the adaptive fuel tuning? the installers manual has suggested settings for rapid learning in terms of delays and whatnot. is it still too hard to get the load/rpm point?

have you tried the ride-brakes method?

I did change the suggested settings to shorten the time needed to autotune, but I don't have them here. The stock ones weren't getting it done. You could really see a huge hump in my map that wasn't getting pulled down. I can get them tonight or tomorrow.

The biggest problem is hitting those cells. Yes, you could ride the brakes, but trying to balance them to hit the 100+kPa cells smoothly and consistenly other than WOT is a bitch. Besides, I like my brakes too much. It was just easier to stare at a boost gauge and hold a pressure as the RPMs climbed. Pretty easy, actually.

I will be able to supply a much better base map with 600cc injectors now if anyone is interested. WAY better than the one originally sent from my stock injectors.

Yep I am interested. Please post it up. Just export the fuel map itself if you can. I am also interested in what you used for the adaptive tune settings.

You know I think I misunderstood the range adjustment on the autotune. I thought the tolerance was variation at any given RPM. But it sounds like based on your description above it means within the RPM column on the fuel table. For example, if the tolerance is set at 150 RPM, it will not autotune the 4000 RPM cell (at X kPa load) unless I am between 3850 and 4150?

You got it. Unless you are in the prescribed band, RPM AND kPa limits at the same time it won't do anything.

I can't upload the ecu file. The attachments section won't allow it. PM me your email and I will send it to you.

FWIW, for rapid learn I used Rapid Learn 150 ( can go to 250 at the beginning for gross adjustments), Load Tolerance 7 kPa, stabilize time 150, update period 150

For slow converge RPM tolerance 150, load tolerance 5 kPa, Stabilze 500, update period 200.

Now that I think about it, I think these are the settings that I gave to Travis when I sent him my base map.

i searched the manual a good 10 minutes before I realized that slow converge and rapid learning were the same damn thing with just different levels of aggressiveness (if you want!).

cant wait to get this bitch fired up!

Yep OK makes sense. I think I'll have to widen up the bands some more initially since it seems like it would be tough to hit RPM and kPa at the same time and hold it.

Will do

Yep I think you are right on the map you sent Travis. That is what I remember seeing in there.
