(Not*) Mediocre 242

yes how for how much?
I've got it listed in the HTG group at 1000 USD, but I'm willing to negotiate and make a deal. It comes with spare terminals and a bracket I made for it. It's just going to sit if I keep it.

I switched up a few things and am finally happy enough with my transmission to post some results. Here's a video. It includes a short low boost (20 psi) pull. Please excuse the rattles and screwdrivers in the passenger footwell.

@RoadRacer4Life here you go ;)


I removed the HTG GCU and converted my setup to be controlled by CanTCU (https://www.canformance.net/). CanTCU uses a stock BMW TCU in the gearbox and essentially translates outputs from the ECU to what the BMW TCU can understand. This is different than the HTG GCU control method which takes full control of the solenoids in the gearbox. I could never get the HTG shifts to a point where it felt comfortable, reliable, and safe to drive on public roads.

Shifts with CanTCU are awesome. They're smooth, fast, and reliable. We had to adjust the shift points slightly in the BMW TCU as it was limiting me to 6500 rpm in manual mode because that's what the 2016 BMW 750i my TCU came from was programmed to do. Now that is fixed I can go all the way to my rev limiter. I also have BMW drivelogic modes (Eco Pro, Comfort, Sport, and Sport+) as well as some other BMW drive modes (Drive, Sport, Manual). It feels great and is working exactly like I hoped it would.
Thanks for sharing 4 questions for you if you have time. what shifter? Domiworks? And what feedback is needed from the ECU for this to work ? i see it says brake and DWB is this correct ? do you know if would TPS be a option ? and what gears/tires are you running and how do you like the gear spread? Thanks

It's a DCT shifter. Domiworks sells them now, but he didn't when I bought mine, so I got it straight from the guy who makes them.

You need at minimum brake switch, RPM, TPS, and MAP. You could probably get away without DBW and use TPS instead, because DBW is really just used for downshift blipping/torque control.

I have a 3.73 rear end ratio and 245/45r17 size tires. The gear spread is good. 1st is short, and I can cruise at like 80 mph at 2500 rpm in 8th.

Thanks for the info :-) (y)
 
One of my headlight trim pieces somehow fell out while I was driving and I didn't notice it until later. I didn't want to spend $200 or whatever someone wants on a GTX set to replace the one that I lost so I designed a duct. My buddy printed it for me, and it feeds the stock holes in the core support. My air filter is right behind those holes. It's unlikely to really do much, but it's cheaper than buying another trim piece.

Here's what it looks like after a good amount of sanding/glazing putty and paint.

Oh man that is awesome
 
I pulled my door cards, put some butyl sound deadener on the door frame with some 4mil plastic sheeting as a vapor barrier and put this new to me black door card on.

I just removed the speaker since my old ones were mounted in the door card and I didn't want to drill into this one. I'm planning on making some speaker adapters out of sheet metal, but I'd be happy to hear about any other good solutions. When I pull the card again to install whatever speaker solution I'll fix that annoying poking clip.
 
5.25 speaker availability is much better, that's the biggest advantage. 5.25" won't have significantly more bass than 4" speakers.

I gotta disagree with you there. You can set the crossover on a 5.25 at 80 to 90 hZ and you will get a lot more bass out of a nice set of 5.25.

OP, sick build, love it!
