I had a problem that WGDC was going down even if load targets were not met. Injector duty cycles were up to 90% when Max Injector DC was at 80%. It started to limit WGDC after exceeding IDC 80%. This has been confusing me for some time, especially after running higher ethanol mixes.
Now with version 1.6.2 I can raise max value and WGDC remains hi, wastegate closed, loads up, even if IDC gets up to 94%-95%.
Great, once again!
Only drawback is that now I don't always get reliable Virtual Dyno plots due to some wheelspin on 4th on dry tarmac with winter tyres
Version 1.6.2 rocks!

Keep actual IDC < 100% or your injection will creep into the previous cycle's exhaust stroke.

Have to keep eye on that, today I saw IDC 97% @6000 rpm with pig rich stock lambda 0,67, stock fuel pressure and E30. Time to upgrade relief valve & up fuel pressure I guess.

1.6.2 is an interim release for those with larger than stock turbos who need > 80% injector duty cycle. It is available by request.

Not in 1.6.2. It was just to address the injector duty cycle limit.
Version 1.6.2 rocks!
Thanks Steve. Is there maybe a new version on the horizon that caters for everyone?
