It’s official. We have full custom tuning access via OBD II !

Yeah we have been getting very little info from HPT and there are still a lot of questions in the air. I KNOW for a fact that they rushed this out because SCT leaked they were going to have their s650 solution on this monday (tomorrow). HPT wanted to be first to market. They are about 75% there with everything. There is a laundry list of items still need to be worked out.

Reading with VCM editor is still broken. I was lucky enough to get an updated 25 GT cal directly from HPT because we pay for their highest tier dealer/resellers program. So I had a working stock cal I could tune and flash because flashing is working well.

There are new betas of their VCM suite being added hourly that is fixing all sorts of bugs and quirks with editor and scanner.

With all that being said, I have a solid E85 tune for any 24/25 GT and DH both manual and 10R80 that I would sell to anyone. I've got almost 30 hours of dev and testing in it and I've driven close to 500 miles on it this weekend in my car in FL 97* heat.

As I said I've beat this car to within an inch of its life. Kudos to ford. Its taken it like a champ. And the car LOVES E85.

When I tell you it feels like a different car, I mean it. Its an absolute blast to drive on the stock tires. My DRs are going on right after I put it on the dyno to get our numbers, but on the stock tires in stock trim with full E85 tuned, its a riot to rip around in. Im hoping we match the 460ish that most are seeing with these completely mechanically stock on E85. Mine is taking all the spark I would want it to have on full E and it loves it.

Plus I have some super secret VCT cam angles for wide open throttle that should make power all the way to 8k RPM. We will see in a day or two...

Thank you for being so transparent.
All this is very interesting to read about.
Curious on your E85 tune, most I get by me is e70, is that still ok to run on and will I get similar results?

I'm also really curious about Ford locking people out via an OTA update.

I remember when BMW did this on the f80 platform. A few tuners had finally unlocked obd2 flashing and BMW patched it if you brought your car in for dealer service with a 'mandatory' DME update. I'm unsure of the current state of things, probably more back/forth, or BMW doesn't care as much now that f80's are going out of warranty.

More transparency coming, strap in.

In all honesty thats more E content that you probably need. We see peak knock protection around e50-e60 actually. The reason full E is preferred is the slight extra cooling you get from that extra ethanol and silly enough its just easier to straight pump and go. No need to blend fuels with 93 to get to e65.

The GM guys LT1/4 cars have this same reality but they are able to run real deal flex fuel sensors, so they can see the actual E content in real time and its fed directly into the PCM to be able to run simple and safe flex tunes. And their problem is that their fuel systems are not capable of running straight E85 (maybe the LT1s no boost). The LT4 cars even stone stock only are DI not DI/PI like our cars and they dont have the headroom to run full E. So blending to e50 is able all they need and all they can handle. But you also get all the knock protection you need as well at that level.

I saw the same on my hellcat. I could run e50 and get the same peak spark advance that I could on full E85. No knock, no more spark needed. But again blending to e50 was a bitch and just pumping straight E in from the pump was much easier and cooler honeslty.

So these MG1 PCMs arent locked. They are encrypted. They dont need to be unlocked, you just need to have the OEM encryption keys to do the key exchange to write the tunes. Ford wont be able to lock us out. Unless they change the encryption keys. Which I dont think they can or would do over the air. That would be like a TSB dealer flash thing where they reflash it stock with updated encryption. No way they are doing that, but I guess anything is possible.

But I can tell you this little secret. Dont tell anyone.

Ford (assisted) in this endeavor after a lengthy survey of past and possible customers for the s650. And the #1 reason people said they didnt want to buy one was lack of tuning support. imagine that... This was telephone game rumor a fellow tuner told me that supposedly came from a Ford OEM calibration engineer that he knows. So grain of salt.

Ford got smart and said, fuck it. These things arent selling. Well they will be now. RIP s550 values.

So that's now HP Tuners and SCT. Heard anything about the PCMtec camp?

Yeah we (P1 ownership) work with them closely and I dont believe they saw any of this coming. Its going to be a while for them to get to this point im hearing. They are still sorting out their product for the s550.

I figured that would be the case since they're all the way in Australia. Btw spot on with the GM stuff. Lt1 will do full E85 NA stock cubes. I didn't have to mess with fuel on my SS until I bored and stroked it to a 427 then the low side fell off so I had to add a aux pump plus a 32% fuel lobe on the cam.

Bingo. And cam on an LT car is a big job. Pan has to come down to get front cover off. So basically lift motor or pull it.

Does hp tuners havea fix in the owrks for the inability to read factory tune out? just curious.

yeah
and whipple support soon

Huh. So to quote someone from earlier in the thread:

Unlocked right as Ford introduced 0% APR for 48 months - it's almost like they know how to sell cars

This is great to hear, I thought I was on the low side at e70.
So, what’s the biggest danger when running straight e85 tune?

piss poor gas mileage. That’s all I can think of. Maybe getting some bad winter blend where you are. Or leaving E in the tank too long and not running it through. Before winter you’ll want to run it all out and switch to a fresh tank of 93. Make sure you have a 93 tune.

 

[MustangMental]

Has anyone seen any Helion turbo numbers yet?

Availability. Around here Meijer is the only place to get it, each Meijer store only has ONE E85 pump, and they close at like 10pm.

Not danger, but a drawback.
