Drive Pressure Data Logging, Part 1
- Thread starter McRat
- Start date
well i dont know what the hell is going on, The voltage is all over the place
after a 1 hour log the average voltage from the Aux Voltage 1 is average = to drive pressure but it spikes all over the place
to Me its not the formula,but more the sample rate of this selected PID it has so many readings per sec that you can not even monitor it while driving,at idle its fine?
Anyways its cristmas eve and i just got a bottle of Don Julio Real so life is good:alcoholic:
ON EDIT: I need to learn to stop posting under the influence
Merry HO HO everyone

How's Mr. Julio treating you this morning
my personal drive pressure and boost is low and cylinder pressure is high:barf:
Im going to have to tinker around with this some more....later
here is a calibration sheet i built that should work for all ranges of pressures and EGTs
On the gauge I seen close to 55PSI on the gauge so matching that up

with this log a person should be able to see what vane posistion,boost and drive prssure reflect.Also Timing and fueling can be referenced if I was better at building Maps in EFI it in theory work the math for us,but thats out of my leauge
Pat loved what you did with the Data cable and useing it to tie into EFI
Pick your flavor here: you will need the wire harness and then choose the range of the desired pressure you want to log, This can all be done for less than 100 bucks

I can now build the correct calculated PID for any of the sensors

LAME....EGTS wont log this way?????????
Im going to talk to Autometer when i get a chance,they made this option so they could hook up the autometer data logger.

We can't seem to get the 0-5 volts required from the back of the gauge to go to the V2. It either isn't there or my gauge is NFG. The sweep works fine though. Or we are using the wrong pins on the autometer gauge - we'll see what autometer has to say.
Whats the sure fire correct way to log these types of things these days? Just leafed threw this thread and im sure you guys have it figured all out to a science now.
