    Default WHO HAS .PID and MAP files for ATLAS pcms???

    Hey guys....Bought the Atlas stream today for the Cobalt SS.....

    I wanted to be able to do more with it for scanning and stuff....I found it to be different than the V8 stuff I've been working with and I could not accurately log KR....

    Does anyone out there mess with these and have some .PID files and some maps that you can make available to me so I don't have to do this from scratch.....?????


    Thanks

    I used default dash and pids and was able to run the complete default dash and record but now what? This was a 06 Envoy 4.2 (mine) but not sure what to tune on this thing.. Will it always be boring?

    Start by taking like 70-80% of the TM out of the trans, that helps a lot. Lower the shift times and up the line pressures. Before I figured out how to tune the engine just doing trans tuning for a normal 4L60E helps a ton. You can run 0 TM, 0 shift times without problems, the 4.2 doesnt make enough power to kill a 4L60E. Ive been running mine this way for probably 25-30K now with 0 problems.

    Also, change the PE delay (cant remember if the P12s have this yet).

    I have tuned on a couple of P12s , mine and a friends both 06 TB , there is not much to do as of yet , did some to the timing tables , trans and PE .
    I have noticed that logging scans that the timing seems odd , one thing is the darn timing axis , they used 128 , 256 , 512 as RPM values , weird .
    Seems you get .02 in all the cells when logging KR , again have not gotten into a lot of tuning on one seeing not much to mess with .
    I have the TM at 0 (zero) and shift times at 0 (zero) as well , but have not bumped the line pressure .
    Have be careful with timing seems it will throw a KR sensor code if to much is done , have had this happen twice .
    Rev Limiter raised and 1-2 shift RPM raised , less bog at shift .
    I do PE at 1.15 (EQ) , seems to like that value .

    I've tuned a few Cobalt SSs and I haven't found anyone with maps or pids....

    Most especially KR...I'm spooked about doing any more aggressive tuning with no KR maps or pids.....

    Anyone?

    I just changed the default KR map to reflect the P12 RPM values , haven't had time to try it but think it will work .
    Copy with labels and paste to "column" (RPM) with labels , I think the "row" (Kpa) values are the same .
    Might have to make our own MAPs for the P12 , if no one at EFILive picks up on this and includes some for us .
    The latest Options.ini has a list of PIDs for the P12 in it .
    On a side note , GM did a TB 4.2L with twin turbos , would love to have that .tun for playing with .
