    Default Mislabeling: IFR & IPVA Row Labels

    Sorry, didn't know where to post this, but I felt inclined to help out the community.

    I came across a mislabeling in EFIL. Basically, on the Gen 4 vehicles with the double range IFR (127 lb/hr versus 63.5), on the "Injector Flow Rate" and "Injector Pulsewidth Voltage Adjustment" tables, GM went to a 20 kPa per row label versus a 16 kPa per row label. EFIL uses in increments of 16 kPa on these vehicles.

    I was working online with Christian from Auto X Dyno tonight, setting up some injector data for a twin-turbo 2010 Camaro he's tuning tomorrow, when I noticed the error. I saw it instantly, since an unnamed competitor of EFIL (I'm considering switching over ) also had this issue back late last year (which they corrected in Oct. 2009).

    Hopefully Paul will read this and get it corrected ASAP. For those of you who have aftermarket injectors and have been tuning (or had been tuned) with what you thought was proper injector data (i.e. those who are using Greg Banish's [eficalibrator] calibration data for them), you may want to revisit your injector tables once you get the corrected database, as your inputted calibration data can be way off, especially in the higher kPa/psi. If this is the case, you'll need to input the correct data, and then revisit your MAF and/or VE tables (hopefully you use these, and not rape the PE table, right? ).

    Here's what I'm describing ("Wrong" is how it is currently listed, but "Right" is how it should be listed):

    Code:
    kPa
    Wrong	Right
    128	128
    144	148
    160	168
    176	188
    192	208
    208	228
    224	248
    240	268
    256	288
    272	308
    288	328
    304	348
    320	368
    336	388
    352	408
    368	428
    384	448
    400	468
    416	488
    432	508
    448	528
    464	548
    480	568
    496	588
    512	608
    528	628
    544	648
    560	668
    576	688
    592	708
    608	728
    624	748
    640	768
    I hope this helps!

    Very Sincerely,

    James

    Hi James, thanks for taking the time to post this.

    So the step is 20kPa, and what is the starting value (is it still 128kPa)...? Edit: see my post below

    Hey Joe, no worries, and you're welcome, sir. I love helping others!

    If you look up in my post above, I had a [code] tag that shows what is wrong and what is the correct labeling (yeup, 128 is still the starting point). Lemme know if you can't see it? Thanks!

    Hi James, thanks for letting us know about this issue. It's certainly something I missed when they changed the table structure. The axis range is hard coded in the OS (easy to miss the change). Good timing as we were getting ready to do another update so I can include the fix.

    Cheers,

    Banish and I where just talking about this and I pulled the following data for conversation;

    STOCK 2006 ZO6

    VAC Kpa of 0=5.1536 grams/sec

    STOCK 2008 ZO6

    400 Delta MAP Kpa (or 0 VAC Kpa)=5.2588 grams/sec

    STOCK 2011 Camaro

    400 Delta MAP Kpa (or 0 VAC Kpa)=5.6880 grams/sec

    However at 336 Delta Kpa the grams/sec are 5.1790 which if the scale is wrong in the current configuration, there is quite a shift in values!

    Hope we can get this figured out cause I HATE guessing over this stuff!

    Howard, here is what the factory 2010-2011 Camaro should be below. So, therefore, at 400 kPa, the flow rate is 5.2585449 (I accounted for precision).

    Code:
    Labels	Flow Rate
    128	2.974609
    148	3.198486
    168	3.407959
    188	3.604981
    208	3.791992
    228	3.969971
    248	4.140625
    268	4.304199
    288	4.461914
    308	4.614258
    328	4.761719
    348	4.904785
    368	5.043701
    388	5.178955
    408	5.310791
    428	5.439453
    448	5.564941
    468	5.687988
    488	5.808106
    508	5.926025
    528	6.041504
    548	6.154785
    568	6.266113
    588	6.375488
    608	6.483154
    628	6.588867
    648	6.692871
    668	6.795410
    688	6.896484
    708	6.995850
    728	7.093994
    748	7.190918

    Can we re-awake this issue??? To me its a big deal....haven't we been through enough trama in just getting the data let alone not placing it correctly!

    Sounds like an easy fix but I don't know the behind the scene stuff!
