The available maps have to be stored on the ECU? Seems like problem solved if you can store them on a phone and switch them as needed. Probably way more expensive, but you could just have 4 maps (pump, e30, e40, e50) and switch at the time of fill up. Only other question is the risk...

Unless you can reflash at the pump, yeah it's problematic in my opinion. I'm thinking it's a laptop and flashing software procedure?

That is probably the most crucial info. If you find yourself without ethanol, or a bad blend, and you're tuned for e50, then you're screwed until you can remedy the situation. This is the kind of thing that makes me call it a bandaid. And it's not like you can just switch to a pump fuel map...

You literally said you won't list the differences in another thread in an attempt to do just that. Embarrassing.

Okay just checking, everyone likes to skirt around the question. Thanks! Seems like a waste for no flex fuel capability though.

MHD can do flex, methanol, and port injection?

Your first paragraph does nothing to educate. I'm asking for specific features that ECUtek enables but you can't get with BM3 and MHD. So far it looks like Flex fuel is no good, so that leaves you at what, 600whp max? Or do you have to tune for one ethanol percentage? Sounds like a fucking...

Oh wow, so I can run ECUtek, flex fuel, methanol injection and/or port injection? I was thinking there was a reason for ECUtek being so popular despite being more expensive (i think?).

So like I said, flex fuel and what else isn't possible? I forgot that Bootmod3 and MHD were the best tuning methods for the Supra. What was that other one though that seemed pretty popular? And yeah, anything that involves shipping overseas in which any shipping issues results in a car...

Having to send your DME off to Finland for over $1000 while still not getting full tuning functionality (is it flex and meth injection that doesn't work?) Is barely even a band aid. Can you even make changes for the tune after it's flashed to the DME with bootmod3?

Band aid at best.

You tuning folks are going to run out of new customers pretty soon unless you figure out these encrypted DMEs.

If someone is stupid enough to pay that much for an ECU, let them pay it. That's a different story from hoarding all of the ECU's and then price gouging based on your limitation of supply.

I will be ready, going to take time off and be camped out in NC ready to be the first. Leaving tonight! You better be right.

What about now?

I was talking about OEM pads. With those it's difficult to maintain braking distance in faster tracks. I'm sure moderate upgrade pads are more than enough for most situations though.

Slower tracks sure, but doubt they'll handle >140mph braking every 30-45 seconds for half an hour. Stock pads were not ideal (but still usable) on fast tracks, on slower more technical circuits they're fine, totally agree.

I had a GenV Viper 2014. Supra is faster. C4S was even slower than the Viper. All day long I was passing Cayman GT4s and a few purpose built Cayman track cars. At Summit Point a 991 GT3RS wasn't getting away from me and an AWD M4 wasn't able to keep up (and that track is perfect for that...

Later and more consistent braking. They're super noisy but the best braking upgrade you can do unless you start getting into custom and mega expensive stuff.

I've never had a fuel starvation issue, and the brakes are good enough for a 145mph braking zone, 135mph braking zone, and 160mph braking zone at VIR full course, and that's every 2 minutes. Not ideal, but upgrading to $1000 pads only helped a bit. I've owned a Viper and Porsche 911 C4S before...
