You guys crack me up. I will see what I can do about the dyno numbers. Also we do have our track day coming up we would love to have you guys come out and lay down some numbers for us!

My V8 3 bar runs strong and the engine / turbos sound a lot different too and the transmission downshifts faster, up shifts faster, and holds the gears longer even in "D" mode if it senses you may want to hold that gear for more throttle / acceleration.
I've been meaning to post up that I regapped my plugs to .32 and now have been getting 31.9 mpg at 65mph and 30mpg at 70 mph and a lot less black crap all over my exhaust tips

30MPG at 70? Jeesus; I got 24mpg right now at 75.
Plugs haven't been touched; Ford will replace them at $384 but stock. I'm not comfortable taking them out for fear I'll break them.
So I probably won't regap; I thought about going to 0.30.

Is that MPG real or what computer calculates? If its real world tested, then we should all recap our plugs to .032.
Thoughts? BTW, I have an '11 so the v8 tune does not apply to me! I think!

Correct; the v8 tune is for the 2013+

I'm curious...
How many miles does LMS suggest clocking on freshly uploaded tunes, before really loading the engine up?
I have perhaps 35 or 40 miles on 3bar v8, and the no shift incident happened to me again this evening, just as it did early on with the 2 bar v8. This time, it was WOT, missed shift into 3rd. It's exactly as it would be on a standard transmission - up shift, missed gear, free rev. I had to let up off the throttle for it to downshift back into a gear.
Going to put a few more miles on her, and then load the engine up again and see what happens. This occurrence went away and was never repeated after the first two times it happened, very early after the 2 bar v8 upload. I put maybe a couple hundred trouble free miles on 2bar v8 after that.

Unaware of any reason to wait on giving her a push, or any recommendations from any tuner regarding this.
What I am wondering is if the shift problem is only PP... both... or just a few cars? looking for a common similarity in the cars that have been shown to exhibit this behavior

I've always had the nannies kick in during 2-3 causing a mis-shift even with the 93 octane tune from last year (which I've been running until I got V8.)
The only time I don't experience it is if I completely turn off AdvanceTrac, which is an option on the performance package SHO.
I think the computer gets confused of the rapid speed and has a brain freeze during the shift.
It was in one of my AFR test videos where I had it happen at 2-3 because I hadn't turned off AdvanceTrac.

With the v8 tune and then the regap my mileage is definitely better but yes that is based off the computer calculations. I don't know how accurate that computer calculation is but it's still up 4-5 mpg from the previous v7 tune with my plugs at .28. I wonder how large the gaps can go now because my SHO runs flawlessly. I drove like a senior citizen to get those numbers but it's legit. Granted my commute is pretty flat so it's not lugging up hills either.
For those miss shifts I have gotten it too. It's the only bug I can find int the tune but it's the same on the stock tune also. I only get it if I stomp it causing a downshift to 1st that causes wheel spin and the traction control kicks in and I continue to run it up to redline then I get the missed shift. It's something to do with the traction control and reduced / eliminated torque management getting confused.
Simple fix turn off your traction control and it won't happen. At least not in mine.

I have this happen seemingly on an almost regular basis. Car will miss 1-2 and/or 2-3 shift. By then the fun is over and I back it down so as not to continually over rev. My car is non PP '11. It's also happened with TCS both on and off.

This was explanation I got from Anthony. I wasn't completely sold since car is supposed to shift at 6600 regardless of what other parameters it sees.
LMS rewriting my tunes now and looking into. They also suggest something mechanical with car. But I've never seen the issue when running stock. Seems like a strange coinky dink to me.

Can you repost actual mileage in the future? The highest mileage I ever saw real life was 23 mpg and that was all highway averaging maybe 75-80 mph.

I can try. I guess I can fill up, drive to work and back and fill up again when I get home and calculate the actual gallons it took to refill with the miles driven. Hard to do with only highway miles, and me driving that disciplined to not drink up more gas
I'll try tomorrow.Dxlnt1 said:
yeah I don't have that kind of discipline plus my wife drives mine to her daily cross fit class in the mornings and I have no idea how she drives it. My experience is soley based on my SHO computer calculation with my occasional senior citizen driving style just to see how high I could get that number That being said I've been around 23mpg city lol but that's hard to do ever watch the number go down while you're sitting still at a red light ?! These numbers admitadely are under the perfect conditions. Very little stopping, very little 0-50 acceleration, super light throttle like barely pressing the throttle to get it to move, and all done on flat ground just cruising a constant speed.
Is there any information that disputes the accuracy of the computers calculated gas mileage ? anyway if it's off all of ours should be equally off. So if my computer says I get 31 and your computer says you get 23 I'd assume I get 8mpg better ?? If not 8 it's still clearly better.
Maybe it's the weight reduction with my performance package !?
Well sad to report, but it appears the V8 is not as good as earlier versions with respect to track performance. V8 I feel is excellent for daily driving, very well behaved and feels good to the butt-dyno. I had a drag race this weekend and I lost a nearly full 0.1 of a second off of my 60' time. With earlier versions I was getting 1.85's and with V8 all i could muster was a 1.92. The track was well prepped and I couldn't notice any traction issues off of the line, had 28psi in the fronts and 30psi in the rears. In the interest of full disclosure DA was pretty terrible at 3000' but that's why i'm comparing my 60' times versus full 1/8th mile times because i expected it to be a little slower at the trap, but 60' shouldn't suffer. I'm going to give Anthony a shout and see what they think.

^^^It all depends on what you DA was on your previous runs to really have a proper comparison.

I guess I don't see how higher DA does not impact 60' times. Additionally it is important to know the amount of water grains in the air at a time of a race.
Ultimately to compare the two tunes it would have to be back to back on the same track with proper cool down between runs.

Well i didn't say it isn't impacted, I said much less affected. It's such a short distance that variances have to be quite large to affect it. In comparison I was getting similar 1.93 60' times with my bone stock car. For every version of the LMS tune that I've had, in all temperatures at the 5 different tracks in the area my 60' times have always been sub 1.9's, consistently in the 1.85-1.86 range. So for my 60' times to be similar to stock there's a definite difference in the parameter settings between the V7 and V8, probably has to do with dealing with the 1-2 shift hesitation issue.
I agree that the best comparison is as you stated, but I didn't have that opportunity since this was an actual race not test-n-tune and I don't have the V7 on the tuner anymore.
Anyways, this is my experience with the tune, take it for what it's worth.
