The only gas we have here is 89 ron/mon, and my original map was 20050 which I compared to the OEM tune on tuneecu as being identical. We also have a seperate fuel which is 100% ethanol and nothing to do with gasoline which is why modern car engines have whats called a FLEX engine as you can mix both types. Ethanol produces slightly more power (negligable). Of course I can only use the 89 gasoline in the rocket.
To be honest, I may try out the decel map again for comparison, apart from that, I'll be leaving the ECU alone.
