Can you interpret my TunerPRO RT datalog?
Can anyone take a look at a TunerPRO datalog for my Camaro?
I collected some data using my ALDL cable and TunerPro RT.
I don't have the skills to understand half of the information its giving me!

I'm still pretty new to this too, but one thing that stands out is your BLM value. It's sitting on 150 throughout the whole log, which means the ECM is adding a lot of fuel to compensate for something. Also, the engine didn't get warm enough to go into closed loop. A longer datalog with the engine getting up to operating temperature might be more informative.

Can you recommend any howto's or tutorials on this? What have you been using to learn about ECM tuning?
Thanks man!

Ah, I didn't notice there was more than one session in the log. Like I said, I'm still pretty new to this
Pretty much all of the info I have found is either by digging around through threads here, or searching google for specific things like "ECM BLM", etc.
This thread is a good place to start, although it's a little overwhelming at first:

Also, I've found many of the videos here helpful:

Lots of them are OBD2-specific, but the principles are the same. I recommend checking out the "Fuel Trims" videos, they give a good description of how the fuel trims actually work. In our case, INT (Integrator) is the short term trim, and BLM (Block Learn Mode) is the long term fuel trim.
