    What does "crank Refs" mean?

    I'm looking at DFCO settings and under "DFCO Entry Spark", "Blend Time" it says that the numbers in the table are the number of crank refs that it takes for....

    What is a crank ref? I assume it...

    Dang, you're right. Everytime the O2s go to zero its going into open loop because DFCO has engaged. Well, Sir you have helped me learn something today. Thanks!

    Ok, I went out and logged two more drives after cleaning the MAF sensor and the both show the O2s going up to almost 900mV as expected every time I went into PE mode. Trouble is, they still randomly...

    Here's a log file from my drive home from work. Still having random events where the O2's just go to zero during WOT and cruise.

    When I got home, I cleaned the MAF sensor wires with a Q-tip...

    I've been reading the forums and it's been said that a MAF that is on it's way out can cause this. I have had the P0101 code pop up now and then - like once a year.

    Does the MAF frequency that...

    You're right. I didn't see that. Sometimes they go up to almost 900mV like they should and sometimes they go down to around 30mV. They also went dead a few seconds after I came off WOT and both of...
  7. Just need a gut check to see if I've covered all the bases in my tune

    I have been tinkering with HP tuners off and on for a while but am far from a pro. I'd like to get some more experienced tuners to look at what I've done with my bone stock LS1 Corvette.

    Here's...

    Didn't work. 0-60 time was 9.25 seconds. I also wound up with over 9 degress of KR (0-60 run is at 3:27 into the log). Here's a copy of the tune and log. Don't know what I'll try next.

    VVT tuning for Atlas engines

    I’m trying to grasp how the VVT works on my 3.7L Colorado. The stock “High Baro” table (I suppose it should be more accurately referred to as “High MAP” table) which the ECM refers to at...

    Wow, the E67 offers immensely more tuning capability than the old P12! Thanks for the tip Laser!

    I was replacing the last 4 digits to prevent my VIN from floating around the internet, but guess I can edit this post later.

  14. Thinking about HPT purchase - need tune to tinker with

    I'm thinking about getting HP Tuners to work on my 2010 Colorado 3.7L I5. I have the demo download of the suite. Does anyone have a stock or reworked 2008+ 3.7L tune that I could look at to...
