Anyone else read/see this article? Don't think I can scan in any for viewing purposes due to legal stuff but...
Question: Does it look like they hacked the PE table to command a lower final AFR? Why no MAF/VE table tuning mentioned, hummm?
Using the data from their Hp Tuners screen shots they are commanding in their PE tables the following values (Assuming on my part Stoich is 14.63AFR) -
2,500 RPM-3,500 RPM : 1.204 = 12.15 AFR
4,000 RPM-4,250 RPM: 1.234 = 11.86 AFR
4,500 RPM-8,000 RPM: 1.239 = 11.81 AFR
Yet their data on the dynojet wideband shows they resulted in an actual.
My estimate from screen shot of dynos wideband measurements below -
3,000 RPM: 14.00 AFR
3,350 RPM: 12.25 AFR
3,500 RPM: 12.50 AFR
4,000 RPM: 12.50 AFR
4,500 RPM: 12.45 AFR
5,000 RPM: 12.25 AFR
5,500 RPM: 12.25 AFR
6,000 RPM: 12.25 AFR
My opinion: Shouldn't the commanded AFR be spot on to the actual AFR IF they tuned the MAF/VE as we are expecting from PRO Tuners?
