Oh, okay.. Thanks. Did you manually dial them in? How did you come up With the values like KRKTE an so on? I think i'm in need for a good starting point Smiley


Sorry, crank HP, meant that.

I did it manually. Used old tune value as start point, but it was way off. Logging and making changes bit by bit.
Pm your setup.

Got the 980cc in, and made a quick tune for winter etanol. E70-75 ish.

Restricted to 1,5bar of boost but I think it's enough for the winter.

It stopped making power at 18degrees ignition at that boost, so I left it there.

Have no clue if this is any good at 1.5bar, but itt pulls good.

Made 3.12 fats (s4 transmission)

That timing is too low even for a petrol.
Is this an RS or S engine? CR 9.3 or 9.0?
I boost 1.7-1.5bar and have 22-34deg timing on Ethanol
You are not even close, there is ton more power there Smiley

Its full rs engine AZR with rods, inconel valves and springs.

If there is more power available at this boost level, no one would be happier than me Smiley Strange that I had the same torque/power on 20 and 18.

Maybe try to bump ignition more next time? You also know we are  on winter blend now, not sure how big difference it actually makes..

Maybe consider this a decent base? Smiley

But 18 degrees at full power on petrol? Are  you serious? Mine starts knocking and pull timing way earlier than that..

I will attach my latest log tomorrow.
You gotta advance it really aggressive as rpm raises.
Your curve is almost flat after peakload.

There is nothing to advance on pump gas at this point.

Oh, that's quite agressive. It's well over optimum angle map.
Nice numbers there, i see you have Cold iat too. Cold outside?

I will not go over 1.5bar for now, but I can try a rework on timing and report back the results.

KFZWOP/2 is optimal ignition angle at lambda 1. It's not the optimal ignition angle on Ethanol.
