Yeh. I got the 93 part. You mention you're planning meth injection so I was just wondering if e85 is an option where you live.

Actually the MHD is vs parts, right? No e85 where you live?

My last four cars, spanning 15 years, were: '06 Mustang GT, '09 GT500, '13 Boss 302, and for the last four years a '16 GT350. So it's safe to say I love Mustangs. My 350 had a Jon Lund flex fuel tune. Suffice to say e85 eliminated any lack of low end torque. The Supra is the first automatic I've...

So with MHD you can have realtime gauges on the screen as shown above?

Instead of immediately trying to flash again I reflashed the stock file. As a result it went out of diagnostic mode. I didn't realize that I could/needed to re-enter diagnostic mode while all the errors and warnings were flashing.

On the shakedown run I raced a Tesla from a light. I walked away from about 50. I'm ready for e85.

Justin, I did what you said and.....SUCCESS!!!! Mother F'er it's fast.

I tried to flash probably 10 times. I sat in the the car in a catatonic state so I know there was no voltage fluctuation. The dealer was totally clueless about this car. It sat on their lot for four months and I think it is extremely unlikely they would have updated anything.I'm going to go out...

I get it. Thanks.

Well, I can tell you that my car sat on the dealer lot for 4 months before I bought it and they did nothing to it during that time, as evidenced by the fact that it had a "Replace Battery" dash message the first time I started it.

To finally rule out a voltage issue I bought a new battery charger and had it set for 20 amps. The MHD read 13.2v and the same thing happened.

Just to be sure I charged the battery for several hours and left the charger connected at 10 amps. Voltage in MHD is 12.66v. This morning when I tried to flash, after a few seconds it said Section Not Validated or words to that effect. The flash back to stock proceeds fine so I would think my...

Here's another piece of info that just occurred to me. I bought my car a few weeks ago from a dealer in Sacramento but it had sat on the lot for four months and had 10 miles. The first time I started the engine a dash message said to Replace Battery though it started fine. I told the salesman...

Miraculously after connecting a battery charger I was able to flash back to the stock tune and engine started. Since I did not have the charger connected the first time I thought maybe that was the problem so I decided to try to flash the custom tune again. After 30 or so seconds it said Failure...

Apparently I just wasn't fast enough on the button. I did enter Diagnostic Mode and started the flash. After several minutes I got a message saying it couldn't erase ECU and a drivetrain malfunction warning appeared on the dash. Now the engine won't start! What a complete disaster this has been...

OK. Trying to do my first MHD flash. I pushed the start button three times quickly in succession but the system still turns off after about five seconds. How do I know when it is in diagnostic mode?

I set up my Google pay with Paypal and a credit card. Both failed.

Got my first tune and now my payment is being rejected to buy the MHD flasher. Does anyone have a definitive answer for this? Can I just buy Google Play Credit, which I've never done before, and buy stuff from MHD using that? No wonder people hate Android. Any further word on ios?

Good to know. I've already paid for two Twisted tunes because I want e85.

Thanks. This wasn't necessary in my previous car. Minor issue.
