I know that it should be up around 1600Hz on the dataloggs. When I datalogged my colt last year it was maxing out at 1604Hz. Anyways, today when I datalogged my talon the highest reading at WOT was 610.1Hz no matter what RPM it is at. Im getting no CEL and the car seems to be running properly. This was at around 14 - 15 psi.

Just wondering what would cause such a low Hz reading.

Mods:
-FMIC
-K&N
-Walbro 255 HP
-MBC

otherwise stock.

Here is a screenshot of one of my pulls. This is at 14 psi.

I went into raw data mode in exel instead of metric units and I noticed that when I go WOT (255 TPS) the MAFS number maxes out at 97 and stays there. Just wondering if this matches up with the metric units I got.

At idle my Hz is 0.0

I looked at my datalogs from last year on my colt (these are from my talon) and my Hz at idle is 44Hz.

Weird.

My alternator took a crap today if that might have anything to do with the readings.

I will be fixing that, and swapping out my mas sensor and re-log and see if anything changes.

Something definately isn't right, you should have a reading at idle and much higher under boost. Alternators can do some wierd stuff on our cars, re-log after you replace it and we can go from there.

Well i re-datalogged today and this time monitered the MAFS signal. everything seemed fine. maxed out at 1604Hz in boost.. and around 50Hz at idle.

I figured out the problem was somthing altering the numbers when i hot sync the data over to my PC. All the numbers are fine when i look through them in the datalogger... but when i get them into exel and look at them they are limited when they get to around 600 - 700 HZ.

Wierd.
