I did datalog and only thing I can see is that I was too aggressive on timing it was around 19.5degrees and pulled down to 15degrees at peak torque.

AFR was at 11.5

other interesting facts
-injectors are at 70% percent duty cycle WITH meth.
-coolant never exceeded 170 degrees even end of 4th gear

will be interesting to see on the gasket, possible it needs o-ringing?

If the headgasket didnt blow it could of been worse damage. I'll be putting another goetze in and tuning accordingly. It was 100% my fault it was 100% solid and reliable at 3degrees less timing I didnt even adjust boost only timing and this happened.

I was able to absolutely beat on the car for miles on end without issue before this retune.

interesting, its done very well for a stock bottom end. At that level I suppose its on the tipping point and you need to have everything BANG ON.

once summer comes round do you back the timing off a bit again? must be very sensitive to ping at that level

I have it setup so that after a certain point timing is reduced as inlet air temp increases, I do not have to change tunes between seasons

Is this something that you physically have to input or does the IAT take care of this accordingly?

It's a table you program. Maybe I'm not using it as it's supposed to be. I just use the MAT based timing retard table to reduce timing after a set point. I think i start pulling timing after 90degrees, today I only hit 70ish degrees after a 4th gear pull so I was 20 above ambient not including what methanol cools the charge

EDIT:just checked manual, its definitly what its used for

Soo many parameters to tuning a engine, I don't know how you all do that stuff. It seems never ending. Hat's off to ya!

Sold volvo s60r and bought something 100x nicer. Couldnt be happier, pics tomorrow. (It's not an alpina just has some goodies and "alpina" parts)

E38s are fucking hot. Very nice car. Any plans for it?

Mechanically not much just a bit more low, but cosmetically I'd like to change wheels, badges, and front lip.

Lol, I kept my wrx for 4 years, and the s60r for a year and 1 month. And I like this car more than both of those... it's only my extra extra cars I sell in a few months.
