Default Calling all tuners... S/C triggering "limp home" mode?

I'm having a slight tuning problem with my ProCharged 2005 V6. 95% of the time, the car pulls like a bat out of hell. However, once in a while the car goes into the "limp home" mode. Sometimes with the CEL, sometimes without. When it does set codes, this is what I get:

P061B - Internal Control Module Torque Calculation Performance
P2106 - Throttle Actuator Control System - Forced Limited Power
P2105 - Throttle Actuator Control System - Forced Engine Shutdown (it's never actually shut down on me)

The problem I'm having is almost exactly like the one wild stray had with his GT, but his is N/A. It turned out to be a bad tune. You can read his thread here:

http://forums.bradbarnett.net/index.php?showtopic=29036

Basically what'll happen is when I hammer it in first or second gear, the wrench light will trip and the car will go into a fail safe mode until I shut it down for a few seconds, then start it back up. I hear no detonation, pinging, knocking, etc... I have an AEM wideband A/F meter, and I've added fuel to the stock tune from RPM Outlet until the A/F is around 10.5 at WOT. Even before that, the most I ever saw was around 12.

The worst part is, I can't always duplicate the problem. Sometimes, it seems I have to baby the car or it'll happen, making sure I shift before 4000rpm. But other times (like tonight), no matter what I did I couldn't get the **** to trip. Tonight, I went out with a buddy and drove the car hard with the Diablo plugged in, data logging the MAP voltage trying to see if it ever went to 5v. The most we saw at WOT was 4.79. It was about 50F out, and I live at 6400ft (Colorado Springs).

George @ RPM Outlet is telling me to get a MAFia so he can "lock in" the voltage for my specific tune. Not sure what he means, but he's been talking with the guys at Diablo about it and they assure him this will resolve the issue. This is what led me to try checking the the MAP (same as MAF?) voltage.

I had the car custom tuned at Mile High Dyno, and Scott (who is a pretty accomplished tuner) said the MAFia is unnecessary unless you're pegging out the MAF voltage. All five runs on the DynoJet were fine. They watched the voltage, and the car never went into the fail safe mode.

My question is, what happens when the MAF hits 5v? Does it trip this code? I don't want to buy the MAFia if it's not even the issue. George @ RPM Outlet says the MAF is most likely the culprit, based on the fact that ATI places the MAF after the blower and the intercooler. Vortech and the PowerHouse411 turbo place the MAF on the suction side of the system.

I really wish I could nail when it's prone to happen. I used to think it was only when it was cold out, or the engine was cold... but it's not. It just seems to happen when the car feels like being a sh*t.

Any ideas would be awesome. As it is, both RPM Outlet and Mile High Dyno are researching it, but have yet to come up with an answer.

Look at my signature for my car specs. Thanks in advance!

Is no one familiar with these codes? ...specifically, the P061B code?

I just learned someone else from a different message board had that error too, but it was caused by his gears!? He changed his gears, and somehow it triggered the torque management system.... not sure if that makes sense or not, but maybe it'll help?

I've installed a Detroit TrueTrac, but I left the 3.31 gears in.....

Call Matt Hill at Matt Hill Motorsports or Dave Kaufman at Kaufman Motors in Dillsburg, PA. Matt is in NJ. Matt might be more available via phone.

You can get Matt also at www.modularmisfits.com. He goes by "Flobee". Sounmds to me liek you may be overheating or your tune thinks that you are for some reason.

your maf isnt pegged yet, why would you need the mafia? its not gonna do anything for a car that isnt pegging the crap out of the maf. As for your problem i am not sure. but i know the mafia isnt needed at 4.75volts.

It sounds like something wasnt adjusted in your tune. Are you an auto by chance?

Nope, it's a standard. The damnest thing is I haven't been able to get it to happen for 3 days now. The car drives just fine, no matter how hard I drive it. There was a good week or two where it was doing it every other time I jumped on it at WOT, 1st or 2nd, above 4000rpm.

I've had the Diablo in, monitoring MAP voltage at least once a day. The most I've seen is 4.87, but it didn't trigger the "wrench"....

this is a really strange problem. You might wanna shoot justin at www.vmptuning.com a email and see what he says he loves v6's and is a good tuner. I still think you have a tuning problem i just cant think of what your problem might be, and i think he can help you out.

Well, I'm almost 100% certain now that it's the torque management tables. After starting a similar thread over at Modular Mustangs, they all seem to think so... not to mention, it was my initial impression, too.

After reading all the replies, I called RPM Outlet and told them what I thought. He looked at my tune and said yes, he needed to look at the torque management tables.

At the same time, he also said having a MAFia eliminates all the other tune problems they've had in the past, even if the car didn't technically need it. He believes it so much, he's sending me one free of charge.

I sent him my original tune, as well as the edits from Mile Hi Dyno. He's going to combine them, as well as make some changes to the torque table.

Thanks for the replies, and wish me luck! I'll be calling/writing the above mentioned folks if this doesn't work. He said I should have my tune in a few days.

Oh duh i am a dumb *** of course thats why it would toss this code:P061B - Internal Control Module Torque Calculation Performance

That should of been the first thing i saw. Well good deal you got it figured out i knew it had to be tune related. Hopefully you can get that adjusted and be good to go.

Well, it's not fixed yet! I hope that's it. It certainly makes a lot of sense.....

From the he talks about that MAFia, I'm almost excited about getting it, especially since it's free!

At any rate, it'll be nice to have it since I do plan on pushing this past 400 RWHP in the future (cam, ported heads, maybe forged pistons, etc..., plus a 50-75 shot of nitrous for the track).

p061B error code is your traction control system. the specific code is "engine torque management system failure". i have a 2018 mustang GT that does the exact same thing tuned by bama tuners/american muscle. when the tune uploads just before it reboots the computer in my car it flashes the warning on the dash "service advance track" then the car reboots and the new tune is loaded. sometimes i can drive the car for a day before it trips the code, but most times i get about 5 minutes of engine running time before the code trips. if i reset the code with my tuner sometimes it will reset and run fine for about 15 minutes other times it wont reset and i just have to have a gimped car. i have had bama try and fix their tune but it takes 10 plus business days for them to get back to me, so basically i have a 5.0 coyote that runs like a 1980's Chrysler lebaron with a blown head gasket.

also my dealer says he's never heard of P061B error code and cant find it on ANY of his Ford information
