Ok so its time to fine tune this girl.
I Got power were I'm at but I know things can be bigger better.

So I have started to dial in my LTFT's per JeffGST's page and the DSMLink Tuning Wiki.

My LTFT Lo's are pretty decent but my LTFT Mid is really high.

Can you guys see if you could help me dealing with these, and check up on my Dead time and global.

DSMLink Tuning Wiki vs JeffGST says between 320 and 460 for dead time.. Im confused.

Would help to know what injectors you're running.

Just took a look at your log. It looks fine. The LTFT is +12.5, however the STFT is -16.8. This is where I'm a bit faded on knowledge, but I believe it's not making the corrections cause its in open loop or closed loop - one or the other. The coolant temp needs to be atleast 180* before the ECU starts storing the corrections into the LTFT. Basically, the engine isn't warm enough.

I'm running the same injectors. I haven't tried messing with a buncha different deadtimes, but 330 seems to work pretty well for me.

Hmmmm 20+ mins of the car idleing and Im still not at operating temp.

Damm its cold outside!

Yea no kidden. If you're crazy like me, try droppin a sheet of cardboard infront of the radiator to keep the engine from staying so cold. Good old diesel trick.

You can add a number to the coolant offset to make the ecu think you are at operating temperature.
