Cobb AP V3

[murkage11]

On my 2013 ms3 it says I have 2500rpm but the AP says I have 2300rpm? also same thing with like the MPH gauge on the ms3 speedometer it says I'm going 70mph but on the AP it says I'm going 67???

I've had the same thing on my v2 and v3. Not sure why it registers 200 rpms off. I've not paid attention to the mph though.

The AP is correct on RPM. The in-car tachometer is known to read 200-300 RPM high.

The AP is actually the more accurate one straight out of the ECU numbers?

Yes... those needles in your gauge cluster can literally be repositioned on most cars (not sure about this car in particular). As for your speedo being off, that's not typical. Are you running non-OE tires/wheels? Have you compared it to a GPS?

I've found that most speedometers in cars read high (generally ~3mph). I've always assumed this was done intentionally by the manufacturers. If the speedo were ever to read lower than the actual traveled speed that could lead to speed infractions and you know they wouldn't want to be responsible for that shit-show.

So, yeah, this all seems normal...

I'd trust the AP over the cluster.
