Modifying As-Built Data Guide

[solodogg]

Okay, so I did a little bit of playing around with some as-built values this afternoon, mainly the IPC, and found a couple of things that could be helpful for those that are considering adding modules to the car.

720-01-01 xxxx xxxx 6xxx - Cross Traffic Alert disabled in IPC
720-01-01 xxxx xxxx 7xxx - Cross Traffic Alert enabled in IPC

720-01-02 xxx3 xxxx - Easy Entry/Exit disabled in IPC
720-01-02 xxxB xxxx - Easy Entry/Exit enabled in IPC

720-02-02 08xx xxxx - Rear Park Aid disabled in IPC
720-02-02 1Axx xxxx - Rear Park Aid enabled in IPC

720-03-01 2xxx xxxx xxxx - Blindspot disabled in IPC
720-03-01 6xxx xxxx xxxx - Blindspot enabled in IPC

720-03-02 Cxxx xxxx - Tire Mobility Kit disabled in IPC
720-03-02 Dxxx xxxx - Tire Mobility Kit enabled in IPC


Another interesting find...when looking at the axle ratio mods that have already been found, I also noticed that there is another change on that line that varies based on the OEM installed wheels. Possible that this is a slight speedometer calibration, but not sure why the 19" wheel/stripe option cars still has the same value as the 18" wheel, but perf pack and 50th anniversary have a different value. Experiment with this one at your own risk...

726-12-01 xxxx xx38 xxxx - 18" wheels (235/50-18) or 19" opt. wheels (255/40-19)
726-12-01 xxxx xx27 xxxx - 19" wheels (255/40-19) - Perf Pack & 50th
726-12-01 xxxx xx3C xxxx - 20" wheels (265/35-20)

(This is a copy of the thread "Adding Line Lock" in the V6 category. I was thinking I'll add it here also to keep track of it...)

Here's what I tried so far for Line Lock...

Original (2016 V6): 0200 016E (Same part # as 2016 GT PP)
2016 GT PP: 8600 7364 (Same part # as Original) Writing Block 2 Failed - Incompatible configuration
2015 GT: 0200 329F Writing Block 2 Failed - Incompatible configuration
2017 GT: 0200 69D6 (Same part # except the end that finishes with BD instead of BC) Writing Block Failed - Incompatible configuration
2017 GT PP: 0200 329F (same as 2015 GT)
2017 GT: 0200 329F (same as 2015 GT and 2017 GT PP)

I really wonder if the value 760-02-02 in the ABS is Line Lock now...

They all failed except this one: 760-02-02 0200 319E (But as we reported before it throw an Advance track error). I had to clear my DTC because I had the ranch to check the manual that kept showing up even after I put the block back to stock...


Quick update: I've got an idea and here's what I've come up with...

I took the value: 8600 7364 (I know I said it didn't work. Except that I changed it) Here's exactly what I injected in the ABS:

760-02-02 8600 01F2 (Here's where it becomes interesting! Forscan took it without any error and the Advance Track didn't trip! This could be the correct value somehow... I tried my car in my drive way and I put it on Neutral to check if I was on flat level. The car didn't move even though for me it didn't seem flat lol). I thought it'll be interesting to throw here all the values that we tried and it doesn't get any errors...

Here's a screenshot:

okay, so trying a lot of these values on my 2015 EB, and not having any luck.

760-02-02 8600 01F2 - Invalid Configuration
760-02-02 8600 1102 - Invalid Configuration
760-02-02 0200 319E - Programmed successfully, AdvanceTrac Service Msg
760-02-02 0200 218E - Programmed successfully, AdvanceTrac Service Msg
760-02-02 0200 127F - Invalid configuration
760-02-02 0200 73E0 - Invalid configuration
760-02-02 8600 3122 - Invalid configuration
760-02-02 8600 3223 - Invalid configuration
760-02-02 0200 71DE - Programmed successfully, AdvanceTrack Service, Driver mode not available

None of the above values ever made Line Lock option under Track Apps change from greyed out. I'm still believing there is another change somewhere else outside of 760-02-02 that needs to be made.

Giving up for now... :(

Here's another post I said on the other thread (It could be a possibility):

Alrighty, I have some news from a friend that works at Ford. He said we needed to check also in the TCM (Transmission Module) It's possible that the ABS is looking for some data from the TCM. He also said the transmission on the GT and V6 are the same. He also checked couple vin # and compared it to mine and he said that the GT from 2015 and 2016 could have 2 different modules. One is a FR3Z and the other (I forgot lol). He stated that we might have injected a line lock code from a module that has a different part #. However After double checking the values it seems that they were the same... He is sure that it's just a matter of programming and to check why the ABS throw an Advance Track error. It could check for another option to be activated somewhere maybe in the TCM but he strongly does not recommend to flash the TCM with the V8 data because of the rev matching or something...

Take a look at this thread. It's more focus on Line Lock: http://www.mustang6g.com/forums/showthread.php?t=63473

I don't know if anyone has seen this thread from a fellow member here who has performed a EB to 5.0 swap - and was able to get the Line Lock functioning with some help from Ford. He had a base EB with no other changes after the engine swap.

Many have said even with the changes being made with Forscan, the feature appears in the menu but is "greyed out". According to this thread, the reason it remains grey after a change is because the system (ABS) has to recognize it with some driving - THEN it becomes functional:

Maybe some of you can figure out more based on details given in that thread.

That is interesting. I have the PP with the 19" (275/40-19 rear) wheels and tires. I have noticed my speedo seems about 1mph off (shows 71 when going 70 for example). I'll have to look into mine and see what value I have currently set.

Problem being that all of the values I attempted on my EB either failed to program or gave an error message. There might be something else that differs on the GT that allowed it to be flashed after the module was reprogrammed as being in a GT that EB programming isn't allowing to flash.

anyone find anything on the backup camera distance lines being turned on or off? I brought my car to the dealer a month or so ago and they replaced my camera but didnt turn the lines back on. Im too lazy to bring it back and deal with their BS so thought id see if we can turn it back on via this.

I assume that the rear wheels are more important than the fronts when it comes to speedometer calibration. When you say Perf Pack, did you mean EB Perf Pack? FWIW, the GT Perf Pack rears are staggered, they are 275/40ZR19 in the rear. My GT PP Base doesn't have 27 in that spot, it's 58. Also a GT350 as-built I had on hand shows 44.

Anyways, I'm going to download a bunch of as-builts and see if I can't get a clearer pattern to emerge.

I don't know but not necessarily. Going off the fronts would be accurate more of the time. Either fronts or rears could be going slower than the car under braking although not likely with ABS. But only the rears would ever be going faster than the car.

I've yet to drive a car where the speedometer wasn't driven by a cable or sensor from the transmission.

Easy enough to test. Go do a burnout and watch the speedometer.

Far too many posts to read them all looking for the answer to this question.
Does doing this register as a flash?

No. You are not changing the software/firmware, you're changing the settings for it.

Ford has been taking speed from the differential carrier for a while now on the F250/F350/F450s. I haven't checked in a while but they might've gone to the wheel sensors.

By taking axle revolutions gearing no longer matters when regarding speed. Only tire diameter.

sorry, I should have clarified a little bit better, that was from an EB PP car, not a GT.

726-12-01 xxxx xx38 xxxx - 18" wheels (235/50-18) or 19" opt. wheels (255/40-19)
726-12-01 xxxx xx27 xxxx - 19" wheels (255/40-19) - Perf Pack & 50th
726-12-01 xxxx xx3C xxxx - 20" wheels (265/35-20)

Alright, I think I've got this figured out. I pulled 13 different cars with varying wheel/tire options. It's a little weird, but the math works.

726-12-01 xxxx 0827 xxxx - 0827 is 2087 when converted from hex to decimal. I believe this corresponds to the circumference of the rear tire in millimeters - BUT not the nominal diameter. Instead, it's a revolutions per mile kind of measurement. When figuring revolutions per mile, it seems like Ford is using about 96.7% of the actual circumference. I assume this is due to the car squishing the tire into the ground and other effects. Interestingly, Mickey Thompson has a chart converting tire diameter to revs per mile and their conversion factor seems more like 96.3%.

To figure nominal diameters for different tire sizes, I used this tire size calculator.

So anyway, the nominal diameter of a 255/40R19 tire is 687mm. Convert that to circumference and add Ford's conversion factor of (roughly) 96.7% and you get 2087.1mm. Compare this to the decimal-converted value in the as-built of 2087.

The nominal diameter of a 275/40R19 tire (as in the GTPP) is 703mm. Converted that's 2135.7mm vs 2136mm in the as-built.

The only car that I've found where this doesn't hold true is a GT 50th Year Anniversary Package car. Those cars were equipped with the same rubber as a GT PP, but for some reason they're configured with 2087mm circumference in the as-built instead of 2136mm like the GT PP. Perhaps this was an oversight by Ford, I wonder if this makes the speedometer read slow on the 50Y cars?

Here is my spreadsheet with VINs and research and such:

https://docs.google.com/spreadsheets/d/1T1vRZtu-1Y-8Bv4nItTektboTOXYjk5rnZzWBlac8b4/edit?usp=sharing

I think the next step is to see if it will accept a value that didn't come factory on any car to see if we can correct the speedometer for larger tire options.

 

[TexasRebel]

I'll look before I head home today, but isn't the rev/mile a setting that can be changed somewhere? Engineering screen maybe?
