Torque limiting explained by 5 star

DRIVE BY WIRE
The F150 3.5L EB V6 suffers from poor throttle response down low. A custom calibration will have enhanced improvements in better throttle response, step on go pedal, vehicle will respond quicker…this DBW system is a torque driven system, it works by taking a certain amount of torque via engine and wheel and applies it to what the driver foot say it needs; a better way to explain it is its a torque limiter. It only allows so much torque at a given pedal position. Stock tables are conservative and numb at best and that’s why one would feel sometimes a lag or a goofy pedal with DBW systems. For a 3.5L EB V6 this is one of the most critical areas that must be addressed and modified to generate more torque /hp and throttle response. By reworking the OEM strategies makes your 3.5L EB V6 come to life!

Mike don't let these guys who continually come in on these post to naysay and be negative all the time get to you. There are those of us who are excited about seeing performance and numbers put up.

I just pinged 5 star about the 91 tune. I don’t want to spring for 3 tunes since we typically only put 91 in.

Thanks nice to get some positive feedback

with the stock internals of the F150 and expy only being rated by for for 570ftlbs, what is they projected trans life expectancy with the added power. Sure the tweak shift points, that won't change the torque rating. Shafts start breaking and gears start slipping.

I thought that comment seemed a hair low, seems like it's rated a lot closer to 600ft/lbs than you originally suggested...unless my calculations are off...590, not 570.

Edit...I'd imagine like most things having "rated capacities" usually at least 30% from even approaching utter devestation, a tuned vehicle (or one without tuning or tranny tuning) making occassional passes at wot from a standstill, will likely fair well, with shortened maintenance intervals, rather than give a fairwell.
Slightly related, a huge fella in NJ with a blown Coyote F-150 is running deep into the 10's with corn and stock tranny. Yes the tranny is tuned as well, but I'm almost certain he is North of 550ft/lbs at the wheels.

5150 pops is right on with his calculations. 800nm is just a hair over 590ft/lbs.

 

[Mike Wolfe]

Thanks for the updates guys
I agree 800 nm is right a 590 lb ft
Have debated whether to get the 5 star E50 calibration
Problem is would require changing to 93 octane tow/performance calibration when traveling long distances because I do not think ethanol is readily available in many places
Wish it was darn it

So I have read all 23 pages of this.

I am interested in possibly getting a tune for my new 2018 Expy Limited. But I also have a 2015 F150 2.7 EB that I want tuned.

Who should I go with? 5-star? Livernois? Someone else?

What tuner can I get that could be used to program both? Is that possible?

I am a complete newbie. I've used the OBDII link before to change settings using Forscan, but thats about as much reprogramming I have done in my truck.

Ideally I'd like to buy a tuner that would work with both vehicles to save money. Any advice is appreciated. Thanks.

 

[sjwelds]

If I'm not mistaken, the tuner "marries" to the vehicle so you can't tune both vehicles with one tuner.

I have a 5-star tune on my 06 F-150 and my 08 Expedition. Had to buy separate tuners for each.

Maybe they have a multiple vehicle option now that I am unaware of.

Big fan of 5-star BTW.

 

[Jay Mac]

I read somewhere the HP nGuage tuner supports multiple vehicles with more credits. Anyone know about this?

 

[Mike Wolfe]

Call 5 star & ask them
I think the n gauge they offer may support multiple vehicles
Very happy with their 93 octane performance/tow calibration

You will find, the "same ole" from one tuning shop to the next.
One device married to one vehicle at ONE TIME.

You conceivably could you use one device, BUT you will ONLY have ONE vehicle of YOUR choice tuned, at any given time.

So if, for instance you want the ability to have the luxury of having both vehicles tuned simultaneously, and the option to instantly drive either at your own whim, you will need to buy TWO separate devices.

@Mike Wolfe sorry for asking this again if you’ve already answered, but when you have performance / tow tune applied, do you still maintain the smooth shifting or is it more like sport mode?

WOT Shifting is a bit firmer but even my wife does not find it objectionable
Light throttle shifting is nearly the same as the OEM calibration as far as shift feel
Shifting is also better matched to engine loads as well
Let us know how the tune works for you

Like Mike said, good tuning and shift firmness should match RPM, throttle input, and load %.

The oem tuning for the 10r80 is horribly matched for all settings.

Not saying you want harsh or jerky shifting, but there's a very fine line on soft shifting and weak shifts.

It's important to point out that often trans tuning is an additional cost, and with 5* building it in their price is well justified.

I do think 5* has a great tuning strategy, but my rule of thumb is if I don't have the interest to tear it down of something let's go, it stays stock. Same reason I don't mod my x6m. Half the engine back is in German, and I'm still figuring out this whole English thing.

 

[Mike Wolfe]

Some thoughts why 5* got so much hp & torque from E30 & E50 calibrations
First of all octane rating from that mix is probably close to 100+ octane
The evaporative cooling characteristics of ethanol probably improves charge air desnity
Apparently the HPFP along with the GDI & Port injectors can supply enough fuel to support those hp & torque figures
Apparently there is adequate flow though the stock intake & exhaust systems to support that much power
Have owned 6 ecoboost vehicles that I have always tuned I am a supporter of recalibration done correctly
I have never encountered any mechanical issues with any of them & the increase in power & trans reprogramming make the vehicle much more pleasurable to drive

Have contacted 5 star to get a quote for my 2018 F150 3.5L ECOBOOST
Would like to use their 93 octane performance/tow & E50 calibrations
Enjoy the improved performance
However I am not a drag racer & maybe someone who uses WOT power continuously could I suppose experience a failure
5* does offer extended warranties for their customers though if someone was concerned about the longevity of their vehicle
I will always leave my vehicles with stock components & just reprogram the PCM & TCM.
While others enjoy replacing the CAC, Intake & Exhaust systems, I am too old to be interested in replacing parts

BTW tried the Hypertech calibrations on my F150
While they help I do not think they are as refined as the 5* calibrations
For someone looking for a relatively mild improvement I guess they (Hypertech) would be ok though
