MHD stage 1 tune, need help reading data log

SHUwatson · 06-29-2019, 01:24 PM

I recently purchased a 13' 335i with 54k miles. I've installed a cts turbo intake and a cts turbo charge pipe.
Today I installed the MHD tune 1 package running 91 octane. I need some help reading the logs I got from running it.
The timing correction is what I'm worried about. There is 3 map logs to look at. Thanks for taking the time

Your IAT is very high, that will pull timing. You ideally need an intercooler.
Do a correct pull for a proper log to review.

Manual
Put in 3rd gear. Floor the accelerator pedal at 2500rpm then at 6500rpm, shift into fourth then stop log shortly after

8speed auto
DSC off. Do this by holding down DSC button for about 10 seconds and it will turn off all traction control. Move shift lever to S/M, then place into 4th gear. Floor it at 2500rpm- all the way to 6500rpm, then shift and stop log shortly after.
