@Nehpets808 Yes! We participated in a discussion about this idea over here. I could never find sufficient photographic evidence that we could cobble this into working, and was unwilling to take the risk to buy and experiment.
@nanaisu Whatever firmware came with the Roadtop MMI unit. I have had...
This is a BMW platform and it's a common joke that we all have 5 or 6 dongles kicking around our glove boxes. But it's kinda true. The OBDlink CX dongle is good for Bimmercode/Bimmerlink, but will not work for flashing tunes to the transmission or ECU. The Thor and MHD dongles are much more...
I do not own an iPhone and will never own an iPhone. I consider the lack of Android Auto to be the #1 practical failure of this platform. Please do not recommend an iPhone.
I currently have a Roadtop MMI unit. If you have one of these, you know it works reasonably well but does not offer...
Try to unlock your car with MHD from your phone before you buy the external tool. Many 2020s can be unlocked from the comfort of your driveway with no special equipment. My car is an example. I sat in my driveway, hooked my phone up to OBD, and unlocked it right from the BM3 app. No bench unlock...
You'll receive many opinions about this, but this is mine after using BM3, Ecutek, and MHD for over 18 months each.
MHD all the way.
MHD has the right easy compatibility with other parts in the ecosystem that are needed should you ever wish to exceed ~600WHP. Ecutek has this, BM3 presently...
I also coded out TPMS. I don't track my Supra, but it has made life significantly easier with wheel changes, PSI being 2-3 low, etc. It's one less BMW nanny trying to decide for you.
My only other guess is that the battery is critically low, but not low enough to trigger a low battery warning on the vehicle's HUD. It has been my experience with BMW platforms that they are absurdly sensitive to low state of charge, and they tend to spit out all sorts of bizarre and...
I have a sneaking suspicion, as does the poster above me, that there's still something plugged into the OBD port. I'll venture an even more precise prediction that there's some sort of GPS tracker sitting between the real OBD port and the port OP has actually been plugging into.
For example...
Thank you. It has been several months since I used the lever. Down it is!
My macro point is: don't overthink it. Move the lever, jam it open, check the driveshaft. If it spins, you're good. I believe all 8HP51 on the Supra have this drilled hole in the lever to give it a yank. Mine does, and...
The lever moves in one direction: up. If you can push it upwards and get a screw/nut/screwdriver/whatever in the gap that gets made, the transmission will be in neutral. It is spring-loaded, stiff, and defaults to not neutral (down/bottom/end stop) position. Watch your fingers. Works best if you...
It is on the driver side of the transmission. Push this lever upright and wedge something between the bottom edge and the metal tab molded into the transmission casing. You can stick a screwdriver in there to wedge it open, many transmission builders just stick an m8 nut in the gap for shipping.
Finally had a chance to dial them in this evening, and man these feel fantastic. I'm at 8 clicks from full soft on front/rear for road use and you can tell you're on coilovers, but it's so compliant on bumps and cracks. It legitimately feels fantastic.
I think community consensus is that SPL is robust and sufficient for street Supras, but anyone trying their hand at racing should probably cop for Verkline. Verkline parts seem to be better at handling track abuse, according to the HPDE guys.
I don't think I've seen an SPL failure on a street...
If I were to buy my Supra all over again, I would still look high and low for a 2020. Nothing beats unlocking and flashing from the comfort of your driveway. Save quite a bit of money, too.
