Ford Performance Tune for 2018+ GT

^^ that wire has to be extended. So you have to unclip and take some tape off too. You can retape what you can after install. I believe it's in the instructions.

Yeah I remember seeing the instructions saying the harness may have to get extended, but don’t really recall anyone here mentioning it. Did you splice in extra wire, or are you able to get enough slack by unwrapping some of the harness?

And I guess that means you left that gray connector where it was?

Nothing was spliced on mine and all connectors remain connected. There should be enough slack in the cable if you free the fasteners. This is mentioned in steps 24 and 25 of the instructions.

This is the picture from the instructions. Mine didn't look quite like this, but I did remove these two fasteners along with two more. My harness on the right side splits off to the grey connector I posted before. Not even pictured here. I wonder if there are year/trim level differences or something.

No splicing here and i installed myself

Here's a wider shot of mine before, I drew a red line to the right of the harness that splits off from my MAF harness and leads to the "blank" connector.

Maybe I'm pre-wired for magneride? I know there was some discussion of some cars having that.

So nobody else had this separate harness coming off the MAF harness leading to a seemingly unused gray connector?

 

[Rpinaiii]

Yes. I took pics. I have that too. Dont know what it is for. You cut tape to extend the MAF sensor. Then I taped again at bottom right corner of engine bay.

Isn't that plug the 'dyno plug'? If it is, it completely disables all forms of T/C and stability control. I know it's around there somewhere, but not sure. Hopefully others will confirm or repeal that.

That's correct.

Knowing that's what it is, it sounds like there'd be no harm in repositioning it if I don't want to unravel the harness to extend the MAF portion of it?

I don't remember that being an issue when i installed. Just cut some tape to free maf wire and it hooked right up. Did not really have to mess with that connector. Maybe i was lucky!

All buttoned up. Haven't loaded the tune yet, gonna have to wait for warmer weather in a week or so.

So the procal portion was to go to FP site and create your account and then enter voucher under procal, it then prompted to download the file. I then installed procal software then updated it then updated the device once connected. I then went to my car and had the procal download my stock tune. I then went back to the computer and clicked update and then it asked me if I wanted to connect to fp servers, I then entered my login password and voucher again. It then eventually found a tune and wrote a tune to the procal? This is what I now see on my screen, I wondered about clicking update again, but if I do that it asks me to go to FP and enter my voucher and other stuff again, so I clicked no since I assume everything is done on the procal device and it has the performance tune ready to upload to the car so now I have to get the kit installed then hook up my procal?

Wonder what the Flags with number of 2000 means?

Ok laptop was the problem. Had to get a new laptop. All is well now. Continuing the install.

So its been 5 days with the install. 2019 GT w/A10/3.55s/28,000 miles. Bought from Levittown Ford and installed myself. I commute 100 miles a day 5-6 days a week, mostly interstate.

Mods:
Ford Borla Catback
Project 6gr 20" staggered wheels w/265 & 305 Nitto G2s
Duckbill spoiler from CJPP

Quick impressions:

- Overall drivability a big improvement from stock (power delivery is linear, consistent now)
- high rpm feels the same power wise (its always pulled hard to redline with stock tune, hard to tell any difference here)
- 2k and up torque is noticeably better. Even easier to spin tires and fishtail pulling out now. I've had to adjust my muscle memory in my foot. I was used to giving about half throttle to get the car up and going. Now its 1/4 or less and your gone.
- idle is smoother
- hwy mpg went up 1-2 (With my commute I can quickly tell any change in mpg)
- cold start is quieter and less dramatic
- I love the new programming for the A10. The aggressive upshifting in normal mode is gone and much more eager to downshift. Sport+ and everything above that is even more aggressive if thats possible.

I agree with most other posters that said the 20 hp or whatever is not worth $1k so if that is what your looking for then you probably won't be happy.

But for me the 20 hp plus all the other improvements to drivability and shifting I feel that it was worth the $1k.

I'll answer anything else about it.

Thanks Pete, I'm glad to hear feedback from someone with the A10.
