With ACN 91 I.could only run Sport with 20% E85. But log Sport and see if Car is happy. But also 20% E85 I could run Agg.
See rader1 thread, the timing corrections was based upon my build and logs
Great, will try sport and log too see if the car is happy, thanks for the link to data logging, very informative.
