So on the drive back, I made extra effort to do a lot of long/low load pulls up to 7000 rpm. I remember there was a post from Shiv somewhere that it speeds up the learning?

I did the same on the way to Nürburgring today and made extra effort to drive in as many different rpm ranges as possible.

If you say so, I will keep it as it is and drive some more with it. What do you recon with the knock? Was I better off with the 98 octane base timing B?


Strangely I only drove the 98 map for 30-50 km, and the trims all looked ok.

It won't be in closed loop over 130 kph and it won't be in closed loop over 4800 rpm in 2nd and 4400 rpm in 3rd and above.

So do the light throttle pulls in second.

You have to be hitting between 45 and 60 g/s MAF in closed loop with some PI, it's not easy but it happens eventually.


And that Stg1 is way too lean for petrol. I said it looked fine because it looked like Stg1 does, which is lean (openflash seem to have updated it when they've had a customer car in the shop that ran rich).


LTFT should land exactly the same or even slightly leaner than the log with the Stg1 maf scale as the values in both scales between 45 and 60 g/s are practically the same.
