Are there any tuners working on fixing the GT & GTPE's bad tune?

[Electric Goat]

As seen in earlier threads and posts, the data logged by other members seems to show that our stock tune is extremely conservative and our cars should be able to support at least 10 seconds of full power with a much quicker recovery time than what Ford is currently giving us.

Does anyone know of any tuners that are actively trying to fix our 5 second of full power problem?

There has been some experimenting with temperatures but the limit seems to be baked into the computer no matter what temperature is sensed.

We don’t actually know exactly why they put in place, but they probably had a reason. There is likely data they have that we can’t see with the OBD scanner.

I’m hoping with the feedback they’ve received about it they will modify it in a future OTA.

RTR uses a Motec ECU for the Mach-E 1400. That’s probably who would be able to fix it. I’ve emailed both RTR and Motec but so far no replies from either of them.

Here's to hoping that they develop a solution for us ?

Motec huh, that’s funny. Brings back memories….

Hi Jason,

Unfortunately we don't have an off the shelf solution for the Mach E (I don't
believe we have any Mach E's in Australia either).

Our M1 VCU's are extremely flexible and with a development licence allow
customers to write their own code and create whatever control strategies they
like. Although it could be possible to use one of our VCU's to control the
vehicle it would require someone to undertake a very significant amount of time
reverse engineering the factory system and then writing all of the code for our
VCU to replicate the control strategies of the factory system.

At this stage we have no plan to do this work for the Mach E.

Most of the best tuner companies are from Australia. HP Tuners, Motec, Haltech and EFI Live are all from Australia. Until the MME is sold there, and one of these companies have a chance to crack and write the tuning code to adjust parameters, a stand alone ECU is probably the only option.

Boo!

Is the code really that complicated?

From tuning other cars, everything seemed pretty straightforward. Lots of tables (think excel spreadsheet) as well as things you could set fixed values (like tq management or speed and rpm limiters).

I would imagine some of the things we want to fix (like the 5 second limit) would just be a fixed value change (change a 5 to a 10). I’m also guessing we could change 480 hp to 562 hp by removing another restriction (similar to tq management in a gas car).

If anything, I would think a tune would be extremely SIMPLE for our cars compared to an ICE. Not like you’re tuning a transmission, nor the complicated fuel trims and timing tables at different loads!

We have a couple of decades of aftermarket ECU tuning knowledge built on many decades of mechanical tuning knowledge such that dummies like me can Google and YouTube our way into the computer-tuning world. There's thousands of grenaded engines and millions of other less-catastrophic errors backing that knowledge.

We don't have that wealth of learning behind BEVs yet. Most of the knowledge we do have is intellectual property of the manufacturers. The price of gaining access to that knowledge is a willingness to experiment.

I don't even have my MME yet, but even when I get it, I'm not willing to take a chance on bricking a $70k vehicle to get 5 more seconds of zoom. I'm sure if you're willing to offer up your car as a test mule, there are people who are willing to try to crack the code, if you'll just sign the liability waiver.

I think you are making this a lot more complicated than it really is. The vast majority of "tuning" for street-driven ICE cars is done using the factory ECU, with parameter changes via a hand-held OBD2 device. The only real challenge with doing this to a Mach E GT is figuring out exactly what would need to be changed. Once that was determined, its fairly easy, although its possible that it would require multiple module updates, unlike most ICE cars. Ford has occasionally in the past even shared code with external tuning parties..
With all that said, I have no idea what could be done that wouldn't damage things.

I would even be willing to pay money as part of a subscription service to Ford if they would free up the 5sec limitation and/or add some horsepower. *hint-hint*

Really odd how you flipped the script on me.

Why should it be my responsibility to experiment on my car? It’s the tuning companies that should take on the risk as the reward is their ability to make $$ selling the tune.

BEVs aren’t exactly a new thing and they’re going to continue to grow in market share.

If the aftermarket tuning companies want to stay relevant (and in business), it’s in their best interest to crack the code.

I think you're simplifying it more than it really is. You have to crack the encryption, write the code, and target the adjustable parameters all while dealing with a vehicle that is constantly connected to ford's server, with ford having the ability to change it back to stock via an OTA update.

Cool.

Where my nerds at?

I was watching formula drift and this ad came up. I searched for MME and they do make a tuner for it. Anyone tried this?

Should I be the Guinea Pig?
