Well here are some datalog sheets that I ran about a week ago. Tell me how these look. I'm still trying to learn how to read these files still and I'm having a bit of trouble with it. I also forgot what settings they were suppose to be at. Any help with this would be appricated.

 

you need to calibrate the gauges. The manual explains this. The A/F should be 0 to 20 on your Y axis. Your X axis should read rpm.

 

yo speed racer, do u know a shop in NY that has experience in tuning maxs?

I went to T&R racing. It cost me $120.00 for an hour of dyno and adjusting A/F ratio.

 

wha ecu r u using, thanx in advance

 

What ECU pins did you tap into? I tapped MAF/TPS/ECT/MPH/RPM. Obviously the most useful is RPM vs AFR.

For comparison purposes, it's nice to test speed vs time whenever adding mods. Of course, it's best to try and compare whenever ambient temps are comparable.

I've also found that when data logging it's best/most accurate to log w/laptop in car, (pres REC, then log) vs using the black controller box to log.

 

I always thought its the other way around. That logging with the control box produces more accurate data logging. I think it even says this in the manual.

 

Not IME. Look @ the RPM, 7290 My car only goes up tp 7100, and I get more accurate readings when direct logging w/ laptop. Even if I use the same mx+b equation re: RPM (hertz via FSM)

What page does it state that?
