    Re: Everything I ever wanted to know about a Maggie,,,and your gonna tell me!!!

    Mod hell just got worse!

    Took off the Maggie today, so I could ship it back to be repaired. Thought I'd put the car back to stock, cuz I have to go to court Monday. Put the motor back together, and turned it over just for a quick check. She tried to run, but obviously died out. That's normal with the Maggie tune. So I connect the Maggie tuner:
    It communicates, shows my VIN, says PCM has been modified, asks if I want to return to stock, I hit "yes". Tuner does its thing and shows a * in the display. This means it's saving the tune thats in the PCM. Look at the tuner a couple minutes later (too early for it to be finished), and it says "no signal from PCM", "check cable and turn ignition on". I give it another couple minutes, same thing. So I unplug it, and start over. This time, it doesn't find the PCM at all. Now the car wont even crank.
    I tried everything I could think of. Disconnected the battery for at least twenty minutes. Checked all the fuses. Even tried my other superchips tuner. That one told me that the "ignition is not in the run position".
    I think my PCM just got F*d.
    Anybody know if you can "reboot" the PCM?
    I'll call Magnuson in the AM, but I don't know what they can do if the PCM is shot.
    Can't go to the dealer with something like this.
    Should I order a "wait for me" PCM tuned for a Maggie?
    Thanks

    Tony

    BTW Tom just called. He's stuck on the side of the road. Sounded like his Magnavolt might have gone bad. Told him to reconnect the grey wires in the trunk. Hope that does it.

    YUP Mod hell.........

    Murphy's law.

    If you can find him, I would yank the PCM and get Stealth to tune it.

    Start looking for something else to drive.

    I probably should try Rick. Just hard to throw anothe $500 into this right now. I wasn't planning on getting a real tune till I figured out if I want any more mods.

    I meant that as meaning your V isn't going anywhere (doesn't sound like it).

    Sorry your stuck, but the down time shouldn't be that bad.

    Im feeling better and better about this $650 install and then Im probably just gonna get the dyno tune at the same time.

    Im am the least patient person on the planet so I would probably have pushed my car off a cliff by now if this had been me.

    Hope you guys get your cars back together soon

    The Maggie should be back by Friday. Hopefully I can get this PCM issue straightened out by then.

    Toms car is done. Just hope this was a Magnavolt, and he got it going again. At least his V wont be sitting till he gets another one.

    Yup, it was running great for about 10 minutes until the magnavolt died. I noticed that it started revving weird - like the throttle response started getting worse. When I gave it about 2/3 throttle it would kind of hiccup, then kick in. All of a sudden the revs dropped down down down down....

    I ended up cutting and connecting the black and white wires from the large grey wire that runs under the car. It was easier from under the hood and I had a lot more wire length there. It started right up after that, and ran fine for the drive home.

    I guess I should have taken the advice from SeattleCTS-V and added extra grounding wires to the Magnavolt.

    Unbelievable! One thing after another. David's going to love hearing from me again...

    I think your PCM is F*D too. Something must have interrupted the communications, and from what I've read that means your PCM is pretty much fried. You're probably going to have to get a new one,and StealthV I believe is still living out of a hotel.

    I would order a wait4me tuned PCM for only $160 or whatever it is.

    Geez, you guys are having all kinds of Mod Hell fun.

    I'm sure that ground connection is the problem with the Magnavolt,Tom. And it's hard to believe your PCM is "F***D", Tony ... may just need to be reprogrammed? I mean, what would have caused it to fry?

    When I see this all happening, I just count my blessings. Good luck, guys. Hope Magnuson has some good words of wisdom tomorrow.

    I don't think its fried. I think as the tuner was pulling the maggie tune, something happened. Now there's missing information. So the tuner can't communicate with the PCM, and the PCM won't start the car. Obviously this is just my best guess.

    Sounds about right......I am guessing there was something aftermarket on at the same time as the downloader.

    What could it have been? Only have the V1 hardwired, but it was off. I have another superchips tuner. I used that one a few times with no problems.
    I'm stumped on this.
