    Np! Yeah,things could off course quick. I would maybe change the "manifold/boost pressure" parameter to "Manifold Relative Sea Level Pressure (2-byte)" since Romraider has about 6 different manifold reference parameters.

    I actually have to use the 'Boost Pressure' (4-byte) parameter. For some reason, the Manifold Relative parameter (4-byte) actually maxes out at 18.35 psi or something close. I have always had the luxury of basically unlimited parameters and resolution, however. I didn't see the 2-byte version of the boost pressure parameter.

    Do you know what ECU IDs you would recommend using that parameter for Vs. Boost pressure? I will add in to use the 2-byte when possible shortly.

    Also, on a similar note... anybody with a Cobb... Please tell me the Cobb version of the definitions =P

    I ran into an issue similar to this maxing out ~18.5 back in the day. I need to go back to find logs of what parameter that was. I always just log MRP Corrected.

    The "How to Make Useful Data Logs" link I posted earlier talks about some of the Cobb parameter naming differences, if that's what you're referring to.

    The earlier 32 bit ECU's use it (04-07 STI/Legacy).

    Will look it over and update it. Thanks.

    Okay, will throw that detail in.

    Updated. I'm still not confident in the Cobb conversion names I found - feel like I am missing a few more. Will add them if people get hung up though.

    As per what definitions to use for what car.. I'm going to have to let people figure this out on their own a bit. I think there will be a good bit of trial/error with it regardless.

    nice thread man, thanks for taking the time to do this. I want to get into tuning and have started reading some of these books already. I definitely have the know-how, its just a matter of dedicating the time and tracking down all the different helpful threads. This will definitely be a good place to start!

    No problem. I'll do a few more posts as time goes on. I'd like to spend a bit more time on this one though incorporating any feedback. Just let me know if you think of anything that should be included with the material.

    Books are nice - those authors spent a lot of time learning. Might as well soak up what you can. Credible information that's presented in a logical manner.

    How about making one new thread, put the links to the different parts, and we'll stick it?

    Also, Ron, the bottom three stickies are of very questionable value anymore IMO. The Cobb AP maps one is pretty dead too.

    Myco,

    I will probably copy over some of the first post to a new thread for sticky use along with an index. I'd like to restructure this first one anyhow when I have more time.

    EDIT: Created the index page in the tuning forum.
