    Another table that affects this that isn't in the DFCO area - the BRAF settings in idle airflow (in gear values) can't be too high or it won't allow DFCO. If the value is too high it won't allow...

    Reduce the open loop fueling table by quite a bit, try reducing by 25% at a time and as far as the hanging throttle - I'm not real familiar with that OS but on my E67 I played with reducing the BRAF...

    The enable TPS of .11 through most of the range looks to be too high, it has to be less than the set value to enable DFCO. In the log it looks like a closed throttle gives a value of 12.2% which is...

    I had the exact same symptoms and it was the cat tests. Luckily it was a few years ago and we were able to uncheck those tests and figure it out. I haven't done any updates to my software and don't...

    I'm no pro but it looks like a pretty conservative tune as far as timing goes. PE is enabled pretty soon at 15kpa and low throttle for a NA car. Idle is at 750 once warmed up which doesn't seem too...

    This was resolved by grounding the AEM's ground to the grounding output from the MPVI2 pro ground output wire. That uses the 'signal ground' from the obd2 port vs. chassis ground and there was a...

    AEM gauge AFR reading vs. VCM scanner

    30-4110. Correct formula in VCM scanner is being used. I log in lambda or gas AFR and no difference in issue. Gauge is reading about .5 AFR richer at idle and .6-.7 richer in PE compared to the...

    Same issue on my 30-4110 - using the exact formulas for 30-4110 in the VCM scanner and the scanner reads .6-.7 AFR leaner than the what the gauge is reading - no difference if at idle or in PE...

    Wayne,

    I also have an '06 V and struggled with this as the obvious usual calculators do nothing for our car. Adjustment is made by the pulses per mile box under PCM output calibration. To...

    You can adjust your BRAF to see if more airflow helps. Use the scanner controls while it is live and you can adjust timing (only allowed to decrease) to test. On a side note, your low octane has...

    HP Tuners staff - did this never get added to E67? Is it possible?

    They are resized LS3 injectors to 65lb. Unfortunately I didn't get good data from them years ago when I purchased as I didn't have a clue, but was told recently from the seller to use the GM 650...
  14. Need some starting advice on VVE tuning on an LS2 with a LSA blower

    Hey guys,

    I have a nicely dialed in MAF only tune on my '06 V (early E67) and would like to tune in the VVE so I have some redundancy for backup if the MAF fails or at least have the opportunity...

    Can anyone give my tune, specifically my timing table a look and tell me if it looks normal for this build.

    LS2, LS3 heads (~10.5 compression with that combo) and an LSA blower making about 9lbs...

    No, the wheels keep the engine turning. It has a disable rpm so it doesn't get too low and bog or die. I'd be surprised if any fuel is being deliveried. My wideband definitely is maxed out lean.

    An LS2 tune is going to get you a good starting point. Compare with LS3 tune and adjust as needed.

    Dynamic airflow on the left - matches the MAF I noticed. I had bumped it down in neutral from 10.6 to 9. Runs the same. Still nice and low and idling pretty good around 725. I imagine I could...
  20. 2006 cts-v with LSA - car idles great, but interesting question-log n tune attached!

    So my tuner has the base running airflow minimum much above stock. Car just has an LS9 cam so pretty mild. I've been fine tuning some things on the tune. When I am logging I am reading that it is...
