Driving in sport mode--GT with manual---has less off the line in sport mode vs. normal

Those arent dyno numbers. Thats calculated engine tq. The whole tune using calculated engine tq for all sorts of values, tables and parameters. We can actually go into the tune and raise calculated tq values in the tq modeling tables that will effect many different parts of the tune.

Again, this has nothing to do with dyno numbers HP/Tq. This is all calculated values within the PCM based on its tq modeling.

Wouldn’t that make the rear measured amount even lower? What happened to the 418 number?

If it doesn’t apply to the rear wheels during measurement how does it apply to the rear during driving?

Because you're not using the PCM to measure rear wheel tq. You're using a dyno with its own interpretation of what rear wheel tq is.

Those figures I posted are calculated engine tq values used by the PCM to regulate several parts of the tune. You are talking apples to aliens at this point man.

But aren’t you managing my torque?

If youre trying to make some grand point here to prove something, then its well past that time to get to it.

I feel like im talking to my kid at bed time and hes stalling going to sleep asking questions like can you buy the earth or do ants understand english.

Time for me to check out on this one Zig. You win the internet for today.

Was attempting to verify the stated limit, if i’m gonna mod but can’t tune, it’s good to know what the limit is.

I love old muscle cars, but I just bought a Dark Horse with 500 horsepower from a little tiny V8. If this engine had been available in 1969 or 1970, it would have been an absolute legend.

GTO had a redline of 5200 rpm. I sold my 66 GTO a few years ago, almost cried, but the Dark Horse blows away all my old muscle cars, even the heavily modified ones when I was younger, and, of course, the braking and cornering . . .

And this right here is the reason I’m always able to resist the temptation to sell one of mine and get a nice old Goat or Z-28 just for the sake of nostalgia. The DH is just too good, and requires little more than the push of a button and you’re enjoying a great car which as you say exceeds anything from “back in the day”. Those old cars were great fun and still have a place today, but I’d like to spend my last years actually driving and enjoying, not trying to keep a youthful memory up and running. It’s a little like one of your first girlfriends; fun to reminisce but you really can’t ever go back.

Having said that I’d be lying not to admit that my manual HP Dark Horse is more than a little evocative of my sentimental favorite, my ‘69 Z-28. Nothing like tight handling with 7,000+ Rs feeding 3.73s or better!

Not unless you go into the tune and raise those limits.

ZXMustang,

Could you give me a "For Dummies" explanation of what I am looking at? I find this chart intensely interesting, but I guess I read it the same way Zig did, that those torque limits meant the engine would not put out more than 376 lb ft of torque to protect the transmission.

But you wrote:

So could you just tell me what that means? (in basic terms or plain English)

I hope my question is not frustrating, but this looks like something interesting. I just do not yet know what you are talking about.

you’re focusing on the numbers too much. They are arbitrary figures ford put in the tune to modulate tq. They don’t equal actual measured rear wheel tq. They are rough calculations that the PCM can validate and compare to populated tq tables for just about every scenario the vehicle could encounter for this condition this table services.

again it’s an arbitrary number. I could put 738 in there which is the max value allowed in this cells, but all I’m telling the PCM is to not limit tq. It’s like with shift schedules, those are managed by output shaft speed and in order to stop the trans from skipping the 1-2 and going 1-3, I have to set the oss shift value to 10,000 well above the cars ability to reach that value. This is a situation of manipulating the car to do what you want by putting on or taking off limits it’s set to use.

Anyone else as confused as I am?

ZXMustang, thank you for making the attempt to explain it to me, but, like AZ_Ryan, I am not following at all, sorry. I must be missing some things about tuning that would enable me to understand what you are trying to teach me.

You’d need to see the complete picture of what’s in the tune to start connecting the dots. It’s both complicated and simple. That’s probably more confusing it it kind of is what it is.
