Alright alright alright! So I installed my Fuel It Ethanol Analyzer and went to the local gas station. I flash the E50 OTS map, only avaliable for 2021s because apparently they use the B58 O1 Engine model, and then drive around town. I drove very chillaxed for about 30 minutes and then started...

Having a similar issue as this now on my MHD E50 OTS Map. MHD is reading the fault code as 'insufficient fuel for performance level." Drives fine until around 100mph and WOT, then goes into limp mode. But holy hell it pulls so hard!!

Yea the 522 was the torque value.

I ordered a set of these springs today. Can't wait to get them installed!

Installed the Fuel-it Ethanol analyzer kit! Tomorrow, I will mix a tank of E50, toss my MHD E50 base map on, and experience Ethanol blend for the first time

I actually have a baseline dyno picture of just a downpipe installed. No tune, no exhaust, no intake. The shop I went to forgot to do a full on base line before my downpipe install, so I asked to get one with the downpipe before the tune. This is on a 2021. Car ended up making 443whp and 522tq...

This picture is of the car on the EU Z4 springs? Looks great!

Wow man your car looks great. What are the tire specs you're rocking on the Toyo's? Also, how do you like the springs, the ride height, and the ride quality after install?

Damn! That's moving! I'm hoping my E50 tune from MHD can get close to this, that would be literally 2 entire seconds faster than my best 60-130 on their current 93 octane OTS map.

Ohh wow nice! I'm about to be making the switch to an OTS E50 map through MHD and then after some time of playing around with it I will be dialing in a custom E50 map. This gives me something to look forward to. Your 40-100 times are .3 seconds faster than mine but the crazy thing is that you're...

Also, have you tried datalogging and purposely getting this to occur while logging? Perhaps you could capture this through the MHD datalogging software and send it to MHD for them review it and see if it has anything to do with the E30 map or perhaps something else. Whats the mileage on your...

I'm wondering if you still aren't at the correct Ethanol blend for your tune and the car is going into a form of limp mode via the BM3 tune. As for mixing the Ethanol, if you don't plan on running a full fledged flex fuel capable tune, I would advise getting the Fuel-It Ethanol Analyzer. It's a...

PM'ed you!

I mean logically this makes since and I hope this is correct. That would mean I can skip E30 and go straight to E50 and have no worries.

So if I'm reading this correctly then perhaps the reason mine says O1 is because MHD knows it's a 2021 and the 6 port design, and if so that's nice, but why is there not an E30 option like there is for the M1? Now I'm wondering if every 2021 owner who's using MHD also has the O1 maps avaliable...

Wth is wrong with my MHD?

Just out of curiosity, can I get any of you guys with MHD to do me a big favor and open your MHD F+G App, got to Flash an OTS Map, and see if you still have access to the E30 map. For some reason my F+G App no longer has access to the E30 tune and shows an E50 OTS map instead. I have the B58...

Finally got around to using Bimmercode to make some changes. I coded the car to turn the start/stop function off permanently unless I press the button, coded it to where it will always start in Sport Individual mode, and then I coded the Sport Plus Engine and Transmission options into the car...

Yea not that bad. I was doing some digging and apparently stock GTR's run a 60-130 in about 10.8 seconds, so a simple downpipe and tune Supra is close to .5 seconds faster than a car that almost costs 2-3x as much. I'm excited to get my Fuel-it Ethanol analyzer kit in so that I can get an E50...

Ok ok, I was remembering runs incorrectly. The 4.xx second runs were 60-100. I had some time today to mess around with the Dragy and got some incredibly consistant 40-100's and some very consistant 60-130's. All in all doesn't seem that bad for an OTS map, however, I think it's about time to...
