Some more info that should help anyone attempting to tune their MS - here are some datalogs I took. I did this by running the megasquirt and LC-1 as a datalogger over the top of the stock UK ATA ECU. The CLT values are a smidge out, the MAT is also not quite right, but not far off (5-10 degrees). Throttle, MAP, AFR (LC1 set in default 0-5v, 7.X to 22.X AFR). Engine had a boost controller but no other fueling/ecu mods so should be as-stock bar the pressures reached.
As you can see the stock ECU sits in closed loop 14.7:1 for a very large percentage of its life, even at 130kpa and sometimes 150kpa part throttle. You can see it hit 8.8:1 at times with WOT though
I've no logs of advance as I've nothing to measure it with while driving.
I've two more logs coming in the next post.
