awsome write up bro............:rockon:
1st Ford has updates for the ecu for the 2011s
2nd ford does not need to refund your money..all stock cars that blew motors got replaced by ford. At Fords expense.
3rd if you modded your car an it blew the stock motor that sucks but you are stuck with the bill .
Great info! :beer:
Very well said. :beer:
Bingo!
Still not buying it, if you actually look at that log and see the conditions that were met, you would shake your head and wonder how stupid the owner really is. Maybe it is just me, but there is no way in hell you will see me ever log that scenerio lol. And with the increasing number of #8s popping, I simply dont see this log as proof of anything cause I still don't believe that many people are that dumb....but Ive been wrong before.
I'm really confused by your statement. That log is showing a full 5th gear pull from 2k to redline. Not really different that doing it on the dyno for tuning. In sure that the issue in the log was discovered and not intentionally looked for. Just think how long it would take to accelerate to that rpm range. That's why the log is so long in time frame.
So what happens when the car shifts? I mean, say you did a one mile at WOT. Would take roughly ~30 sec. Would we see this if we were data logging? Or would it only happen while in a single gear for this 15 sec time period.
A dj dyno will never take 20 plus seconds, a mustang dyno with a really high load "might", doing something like this on the road is looking to purposly blow your car up. I see the log shows issues, not denying that, I am denying the fact that all these people who popped motors did something that stupid at one point or another. I mean just think about how much room you need to even accomplish such a thing. There other issues going on here imo.

That's my thinking also. 5th gear at WOT for 15sec is FAST.
3.31 car almost stock dynoing in 5th would be a long ass pull
Also for the dynojet of the e63, I feel like you guys have little experience with DI, MBenz is not the only company to run such af ratios on a DI boosted engine. My past DI twin turbo bmw ran stoich till about 5000-5500 rpm as well. The logs showed no signs of knock. Hell based on that dyno, the "tuned" run has issues as the power gets unstanble in the high rpm band.

That gear is only on the dyno. Lots of guys can beat on a car for over 10sec. Again I think it depends what sets it off. It's hard to simulate cyl temp on a dyno. Longer than normal pulls are the only way to do it imo.
Idk why folks think musang is the only load bearing dyno. I have to load dyno jets on higher hp cars or the pull is only 2-3 secs. Can't tune a car like that. A 1000 hp car needs the shit loaded out of it take 10sec lol.
There are more conditions which Ford stock programming will run Stoich at WOT.
The log posted is what I would consider to be our (as tuners) issue to resolve. Despite being one hell of a WOT run, some people DO run their cars like this.
FWIW our 5.0's have 'poor mans' Direct Injection. It's called open valve injection and is designed to do *some* of the benefits of DI without the expense.
OVI is activated at high load only.
Also note knock sensors are dialed in for spark knock (piston rattle), not lean knock.
As seen in ProCal tunes. Reports of pinging yet no knock detected (full 27 degrees of timing advance)

i wish Ford would hire you to make a procal tune for christ sake
Not familiar with what OVI is, but also not sure how PI can act anything like DI. Our fuel pressure is crap compared to 2500 plus psi directly injected onto the piston. Either way that is besides the point, point was that alot of OEM DI cars run stoich air fuel ratios with zero problems. Hell I doubled the boost (over spun he turbos hard) and was hitting 14-15s at peak tq (over 450wtq) with no signs of knock, on a car that hit 300 stock.
Does anyone have any logs to show of our cars commanding these things during racing or normal day to day wot runs?

That brings an idea to mind. If AED is confident this tune will solve the #8 issue is AED willing to give a guarantee or a warranty?
So your saying the procal is not very safe? I've heard of people having pinging issues with it, but haven't heard of a blown engine from it.
Absolutely not.
I applaud AM/Bama for their stance on the issue, but let me be very clear....
The #8 is NOT due to aftermarket tuning. The root cause is in the factory program and as such no tuner should be taking responsibility for issues they did not cause. Sure, we can make it worse, but no tuner will EVER command Stoich at WOT on one of these cars.
