Default Map selection - 12-01-2018, 03:42 AM

Hi everyone!
I've got bmw 440 xdrive. I installed jb4 and down-pipe, so which map should I use? I ran 100 octane (Russian system), I guess it is 93+ in America

Map 1 and 2 is good for now with just a down-pipe.

Make sure to get EWG cable if you are having ***-less D0wnp!pe.

I will say try map 5, you have good octane and Russia have cold climate so I assume you should get good IAT degrees in WOT.

take logs and BMS can tell you best. Have fun

Map 2 is great. But map6 at 4 psi flat maybe better.

👍

Only 4 psi? From 1500-7000?
I would run map5 if your octane is there

After several hundred WOTs with all the maps 1 thru 6, at all IAT ranges, map2 and map6 at 4 psi flat have the optimal acceleration with the most timing advance, while using 93 octane.

Still fine tuning though.
