Been trying to track down a lean light tip-in condition, spent Saturday tuning it.
Turns out whomever had tuned this thing didn't understand how AE works in Megasquirt, and the car was never using it unless you slammed the E36 M3 out of the throttle, which never happens in normal day to day driving.
After getting the AE dialed in (surprisingly easy, thanks to DIYAT's awesome video from their open house.), car was still going lean in the same situations, i just couldn't get AE to account for a slow 3-5% throttle opening (gradual hill on highway situations, passing a car NOT like an shiny happy person, etc).
Drove a bit watching where i was hanging out on VE table and the target AFR table. (Not being used on a day to day basis, i don't run EGO Correction.)
Turned on AutoTune just to see what would happen, and it looks like there were two columns in the low-load are that just weren't tuned right. Spent about 30 minutes driving around doing exactly what used to go lean, over and over and over again, then did a few high load high gear low rpm hammers to make sure everything else was still good.
Think that cured about 80% of it. Drives much better now. Throttle could stand to be a LITTLE more crisp, so i have some slight clean up work to do on AE, but it's a big improvement.
Seem to have picked up better spool and a little low/midrange punch. You know... because that's what this tiny little turbo needed.
Was trying to get a full gear log, but 2nd gear went up in smoke.
Tried 3rd gear from 20mph. At about 30mph the ass end let go and the car tach'd out, spit a few fireballs, and left some solid black lines on the road.
Figured i should probably park it for winter at that point.
To do over winter:
1) Install Swank Force Racing™ custom Bilstein suspension
2) Install Boss Frog Clearview Rollbar
3) Install matching Autopower harness for passenger
4) Install Boss Frog Fender braces
5) Install 01-05 Sport brake setup
6) Convert from 95-spec CAS ignition trigger to NB1 crank/cam trigger combo
7) Hook up VICS
8) Electronic boost control?
9) Install Singular Motorsports hood vent louvers
10) Install Boundary Engineer frame rails
11) Figure out wheels/tires. (205/50 RS-Rs or 15x9 225/45 RS3s.)
12) Purchase Blackbird Fabworx rear spoiler
13) Rework the garbage BeGi intercooler/intake/bpv with homebrew.
14) ?????
15) In Spring, break all the 2554r power records.
