    2014 Calibrated Success Classes

    I added a couple classes for this fall. They are listed on the (new) Calibrated Success Facebook page as events as well.

    I cannot guarantee that whatever FAST is selling is the same as the SD60's (FRPP part# -LU60) that I included in my DVD's data disc. I know that some of the injectors that FAST was selling were just...

    The FRPP 60's are manufactured by Continental (who bought SiemensVDO, makers of the Mototron 60's), so they should be the same thing as long as the vendor isn't being slippery. I actually bought my...

    Other sheets usually just take the Siemens (Continental) data provided at 3.0bar and use the Bernoulli equation (square root of pressure ratio) to solve for a new theoretical 4.0bar flow rate. This...

    Porting the throttle body changes airflow in relation to blade angle, particularly around idle. What the ECU thinks should be happening no longer matches the reality of your ported TB. The factory...

    I've yet to see good data on these injectors anywhere. I suspect that nobody (including FAST) has put them through a complete cycle of SAE J1832 testing to compile the data. Without this data, you...

    That's pretty much what I was already able to generate in V7.x It's the complete report, minus the critical timestamp and mileage at reading. CARB will NOT accept our report without these, so it's...

    Timestamp and Mileage Readings

    I'm trying to use the scan tool to take OBDII data on a project for the day job and I can't seem to get the tool to give me a single screen that shows the current timestamp, mileage, DTC status (even...

    You can't change the 512g/s limit, as this is in the code section, not the calibration data. However, it is possible to scale your calibration data down to stay under the code's limitations and...

    As long as a few ASSumptions are good, you "should" be fine with only measuring one bank:

    1) The intake manifold is designed as a mirror that does not bias air flow toward one bank
    2) Valve...

    The card style MAF works in pretty much any tube diameter, it just changes the working range. (How much total flow you can measure before hitting the PCM's frequency limit.) The good news is that...

    Looking at your hardware and the screen shot of the injector setup, I'd say your highly respected tuner missed a few things.

    These will require scaling to work correctly in the older ECMs. They flow ~60#/hr at 3bar, and closer to ~73#/hr at GM's 4bar nominal pressure, which is beyond the ECM limit. Plan on about 24%...

    1) Yes, you can force the ECM to operate in "MAF Only" mode by setting this to a low number. GMPP does this on their crate engine controllers, and we do it all the time as part of the normal...

    Good question, Joe. I actually took volumetric measurements in the burettes. Mass flow was calculated from volume, so what you see is a change in volumetric flow, which was converted to mass flow. ...
