    Anyone use a Powercommander on an APEX with boost?

    nate007, Once it starts it high idles fine. 2000 RPM or so then settles to around 1300 - 1400. I'll get a look at everything. on the air side. I don't think it is a bad valve.

    Anyone use a Powercommander on an APEX with boost?

    DooAssassin I think that the fix. I was told that there was a way to richen up the entire base curve. Then I could readjust my numbrs down. Watched the video. It looks like he shows 4 settings and runs them up and down. Do you know which one I need to adjust and what is the range? Are...

    Anyone use a Powercommander on an APEX with boost?

    kinger, Cold start issue is I must start the sled at least 3 times before it stays running. I could go out right now (about 80 degrees here) and it will start and stall at least twice. On the third try it should stay running and idle fine. This gets amplified when it's cold out. When it's...

    Anyone use a Powercommander on an APEX with boost?

    FLYBYU How difficult was it for you? Literature states plug it in and away you go, no tuning. True? Do you set target A/F ration and that's it?

    Got an 07 APEX with a Stage 1 MPI supercharger on it. Having cold start issues (starting 3 - 4 times before it stays running). I have been told that the controller I got from MPI can only add fuel to the idle circuit after it has been powered up. Looking for better cold starts. I've used the...

    MPI APEX Stage 1 cold start issue

    40 Degrees out this morning. Stalled once. Concerned that when it's like -20 that it won't start. I'll be playing with the blow off valve. The motor is defineately seeing more air than stock. Blow off valve is closed at idle but starts dumping around 2800 RPM. I believe if it's dumping at...

    MPI APEX Stage 1 cold start issue

    Just installed an MPI Stage 1 blower kit. Brand new from MPI. GEMS controller installed and idle setting at 3. When I cold start at 30 degrees or less it takes 3 - 4 times before it idles on its own. It's lean for sure. I keep adding fuel at idle but still not taking care of it. Anone have...

    APEX MPI hood screen options? what have you used?

    Got a Stage 1 MPI S/C in my 07 Apex. Intercooler might as well have neon lights! Looks good but too much exposed. Worried about getting ice chunks thrown at it and damaging the intercooler. What have you used? Pictures would be great. Thanks for sharing! Marco
