Anyone with PFC experience please help me out here.
I've got PFC D-Jetro on a blacktop with a GT2871R.
Here's the problem....I've always set the boost limit to like 7300, and never had a problem going over or anything. I also have an AVC-R, which I use to display boost and RPMs.
So, on the PFC, I wasn't using RPMs as a monitor.....went to the track today, and on my first 4 runs, when I got done, my AVC-R showed the max RPMs that I hit as like 7500-7600. One time it said 7600 (exactly) and the other time it said 7500 exactly.
I then tried setting the RPM limit to 7000, just to be safe....in the parking lot, slowly took it up to 7000, and it cut fuel at like 6950. OK. Then took a run, and after I was done, it said max RPM was like 7350 or so.
Has anyone ever seen this happen? I have no idea why it is letting me rev like a few hundred RPM above the set rev limit. The fact that the AVC-R read EXACTLY 7500 and 7600 for max REV seemed fishy to me. Unfortunately, I didn't have the PFC tracking REVs during these runs, but it's annoying that it let me overrev, especially since the stock 240 tach is far from accurate when you get that high in the rev range.
