First time logging with MHD

Eracer76 · 10-18-2015, 02:08 AM

I'm used to running and reading JB4 logs on my old 335xi, so this MHD tune using data zap stuff on a Android tablet is completely new to me, especially since I'm a Mac user! lol

Can someone let me know if Im doing this right, and possibly look at my log and tell me whats wrong? I had to do a 2nd to 3rd gear pull because my clutch isn't happy with low rpm roll ons in 3rd or 4th gear, but if I run through the gears its usually fine... (new clutch is going in this winter)

Thanks for any help!

Am I reading that right, that my throttle position is only hovering around 80? If thats true, what would be causing that?

I believe throttle position is 81 fully open. I was worried the other day as well when I saw it at 81 as well after doing my first logs.

Thats good to know, thanks...

Now I just just need someone to let me know how the log looks and if the car is running ok?

You really need to get that 2 to 3 gear pull to really get a good idea whats going on but from what you got things don't look bad. Cyl 5 is taking a little beating with a correction and the LPFP has no reading were two things that stand out.

Thanks for the info... It's a 2009 Z4 35i so I don't believe they have a lpfp sensor... I know I have some winter projects to do... I need to clean the intake valves (55k miles and never been done) and a new smfw and clutch to put in

Yea, that's what I see also - Bad timing corrections on Cyl 5 only, and zero reading for the LPFP but HPFP looks fine.

Move the coil on cyl 5 and see if the timing pull follows. If not, and you still have timing pull on 5, change the plugs to see if cyl 5 clears up.

Other than that, it looks good from a shelf map. When you finish up your winter projects and want to turn it up, let me know. ;-)

Thanks everyone, I'll try moving the coil and or spark plug some time this week and report back... Thankfully I haven't had any misfires though (knocking on wood) and when the clutch does decide to hold, it feels like it's running great
