Hi friends.
I'm new to tuning and recently bought MPVI3.
In the firmware I saw that the stoich is 14.36 as for E5 fuel. My area doesn't use ethanol.
Can I change 14.36 to 14.67 and continue using the car without any problems or need more adjustments in the firmware?
Thank you

Want to improve fuel consumption
I don?t know how that ECU works, BUT I wouldn?t do that.
1. I guess the ECU makes its calculations based on that stoich: PE, Timings, Injection rate etc. Therefore I can imagine it maybe needs to be adjusted.
2. I am just asking myself, how much fuel saving are you expecting? 0,5L each 100km?
The stoich ratio parameter just gets the ECU into the ballpark for fuel corrections, it will still target a 1.0 lambda and use LTFT to get there regardless of what stoich AFR is set to.
Thanks a lot, Ill try to find another way improve fuel consumption
