    Some help needed reading tune in Torque

    I have been trying to figure out if I have a good tune or not in my Solstice GXP. I have some datalogs of my average driving (cold start and some 1-3 gear pulls after warmup) and I was wondering if someone could look at them and see what they think. I think it might be on the edge of extremely aggressive, but I'm not sure... I have an excel spreadsheet of it that works..... The first portion is everyday driving from cold start on....the second run is a pull from 1-3 and the third is a pull from 1-3..... I added the cold start run..... I couldn't add all of it since it was 1MB.

    In terms of safety, always use KR and reading the plugs. For performance, choose something that's easier to monitor than a full run through all the gears. The reason I say this is that it's extremely hard to get the exact same reaction time for shifts. Eliminating those variances makes it easier. Instead, try doing only a 3rd gear pull. Floor it at 57, read from 60-80 mph (or 60-100mph if you've bumped your redline to 7k). This will let you compare more easily because the car will be in a steady-state mode.

    You can also use virtualdyno.net as a tool. Upload your logs to it and it'll calculate whp/wtq. We compared the numbers to a dyno jet pull same day for a Mazdaspeed 3. Difference was 1hp & 1tq when corrected for temp and pressure. Pretty good tool.

    Post a log and your tune. I'll check it out. Seeing you're from MI, I picked up my GXP coupe from a guy in Sterling Heights.

    That's where the problem lies. I can get the Torque data log, but I can't get my tune. I don't have anything to read the tune....yet.

    I wish i could get torque to read boost over 22.5psi, but i need the PID for the lo res boost sensor (not same as PID.2338 as in HP tuners).

    What did you use to log your data?
