Version 1.6.2 rocks!

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

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.

One question.... Where do we get version 1.6.2?

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.

Cool...any new features for those that still run the K04?

Not in 1.6.2. It was just to address the injector duty cycle limit.

Thanks Steve. Is there maybe a new version on the horizon that caters for everyone?
