This function is not available through Dimsport.

Loacated in Arizona (MYNES) and California (ABF) contact Mike of Hubie for more information. We have gotten more into the MINI ECU code. Can even change your low and high speed fan ON/OFF temps to accomedate a colder thermostat. We also turn off closed loop operation within the code when tuning to scale larger injectors. This allows us to correctly scale in the injector without fighting with the ECU closed loop short term and long term trims after resetting the adaptations. When tuning is done, we turn the closed loop operation back on. It's always good the reset adaptations if long term trims are +/- 5 % before any flash is done.

That's not a problem, that's why we have airplanes right? Also I am planning to tune some MINI's in NY coming up soon anyways. I'll keep you posted.

hi everybody

i finally installed the larger injectors (440) two months ago and i faced the problem successfully.

my Air to Fuel ratio is 11.4 - 11.6 at the highest revs. this is a good and safe number.

i run the mini at 7500rpm but after 7000 i face a significant power drop.

i run at 226 whp until 7000 and then i lose many of them...

i will try to retune it again very soon...thank you all for your contribution

Thanosman, sounds like you can benefit from an upgraded camshaft. MegaMini recently released their MM254243 camshaft with excellent test results. This camshaft provides smooth low-end torque and delivers high-end power all the way to 7800rpm (and it's not hard on the drive train). Details of this cam is located here:

cheers.
