    Default Noob needs help with Roadrunner

    Alright, I know it's been a while, but I've finally got the car back together from bodywork and paint and I'm still working on the tune. I've been talking with my tuner and he says he can let me borrow his roadrunner PCM and the cables necessary for tuning, if I can find someone to help me setup a file for auto ve tuning. Can someone help me out with this? Right now my fuel tables seem to be off pretty bad and I really don't know anything about tuning.

    This was my first thread and I have to thank you guys for all your help, helping me figure out what was going wrong.

    Alright, well I read through both of those links and I may just need to try it I guess. Has anyone done this using Windows 7, hopefully I shouldn't have any issues there. I will also need to read through the IAT fix, since my MAF includes the IAT.

    You don't need to pull any wires on the MAF.
    That is old lore.

    Have you read the stickies in this forum?
    There is a bit of work to be done with the cal_link.txt & calc_pids.txt

    +1 what mr.prick said... you just disable the MAF via the MAF sanity tables, this should get you a MAF DTC which confirms the PCM has failed the MAF (and is running from the VE).

    Alright. Well I've been reading through some more of the stickies in this section and man there's a lot of info there. I may just need to get my hands on the RR and program. I'm really more of a visual learner so it's kind of hard to just read about the data that needs to be adjusted and visualize it.

    Can you give me a little more info about this text editing. I followed the link in the faq sticky you posted and I'm not really understanding what I need to do or why. Do I need to change the text for every line listed in the link for the LS1 engine?

    Also, how do I locate the MAF sanity tables your talking about?

    Sorry, I'm just getting prepared here, my RR PCM should be here tomorrow or Tuesday.

    The calc_pids.txt is used to define calc_pids.
    An example would be a multiplier from logged EQ & commanded EQ.
    "({GM.EQIVRATIO}/{EXT.WO2EQR1})"

    The cal_link.txt is used to link a table from the tune tool to the scan tool.
    You add or alter lines in the cal_link.txt for RTACS to work properly.

    The highlighted cell is linked by {SAE.RPM} & {SAE.MAP}.
    It will be multiplied by 2% because logged EQ does not match the commanded EQ.

    Alright, got the RR PCM in today and loaded my tune. This tune is running alot better in my car, doesn't seem to be as rich. So I made a quick base log with this tune, the car is just idling with a few throttle bumps. Take a look and tell me what you think. Also, why can I not view this data in a map?

    Did you load or create a map?

    There are a few too many pids selected in that log, reduce the amount of channels to 24.
