That day was a 0deg C and 1019mb pressure.
Perfekt day for god numbers, Smiley
I am aiming for 11.8 afr.



Did your car gain torque for every change the Whole way up to where you are now on timing? That's kinda sick. We have two e85 racecars, and they are at about 24 degrees

Ahh I see, so now we also need a weather station at home  Wink

No, it did not, BC it is very hard to duplicate same conditions twice. You can do a run, get logs, reflash and do a run agin in an hour, and your car is heatsoaked resulting in 5degC higher Iats.
It changes everything.
Don't be scared RS engine can take a lot of timing.
You are really low in timing.
Tips!! Ethanol knocks when runnin too rich.

Its not timing pull, but i cant see more than 20 even if i have raised timing maps higher.

I found one mistake, i had lower values in KFZWOP than in the two ignition maps! Corrected it now.

It was mainly the optimum angle map that was interfering I think. Tested just to increase mostly on top for now, and it works Smiley

Have to go to Germany rest of the week, but i will tweak this more when I come home!

KFZWOP has no bearing on timing request.

Thats strange, bc I only got 18-20 degrees even if i requested 28.
When I changed KFZWOP to be higher than timing req, then i got 24-25 degrees.

What do you think is holding my timing back then?

Tweaked it more and got some more timing, and a little massaging of AFR. This will due for the winter I think.
Maybe try a 5120 hack in the sprig and get som more boost.

It sure is faster now Smiley Timing is higher, it differs a little from pull to pull though.. Starting at 18-20 ish and is max 29-30 degrees.
Sometimes I get weird timing corrections at like 3500rpm, but not always. Guess it can be fine tuned.

AFR is from 11.6 and maybe 12 at leanest, Didn't notice any trend of it leaning up top, but I also have a little bit of a richer request for safety. and massaged my kfkhfm to get fueling ok up top.

Do you have issues With top leaning?

I don't know if i will make much more Power now @1.45bar boost

Ok. Think that's quite normal that it does that.

Problem is I don't have 5120 hack and map sensor, so Limited on boost. On the other hand, this is quite safe Power Smiley
Not really sure at which Level my fueling is maxed out. The surge-tank With 044 in engine bay sure helps, but not sure how high it can go.

What are you'r plans for fueling?
