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):
I hope this helps!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
