Yeah, though it seems like the controller for the 4hp22-eh takes into account injector pulse time, which will change dramatically when I put bigger injectors in for the boost. And I fear that that will negatively affect the shift points and whatnot. I just can't damn decide. I think it would be trick to have the electronic trans for the whole sport/economy modes, but when it's supercharged, it will likely always be in "sport" mode anyway.
Maybe this, maybe I put the 4hp22-eh in now with m30b34 with their factory harnesses and controllers and make them work like factory. Then, when I boost it, I change over to the 4hp22 (cable-op kick down version) and megasquirt on a m20 harness. Yep, I like that...

Sounds like a good plan... Set them both up for same output shaft so you don't have to change driveshaft. Since both the eh and cable op one can be used in 535/635/735, maybe you can set up the driveshaft to match larger trans out shaft. You'll also need the throttle body with cable holder when you go analog (does that word work?).sigpic

Originally posted by Ether-D View PostI would too, if that's what came with the motor I got. But it came with an auto and I just thought, why not. A manual costs more money (cause I'd have to buy it) and the auto is paid for and more muscle car style.
I wouldn't say more muscle car style, more a different style. Banging gears with some proper horsepower is great fun for road racing. But column shift would be properly badass. Unfortunately my only experiences with BMW of that era's autos are that they're fairly woeful, which is why I personally wouldn't go near them.
Can you mod the valve body so they shift tighter?

Originally posted by whodwho View PostIt does use injector load and will throw the trans into limp mode uncorrected. I had a guy that I was helping with this but he gave up and didn't follow thru. I think that adding a OBC correction board from Steve @ SeattleCircuit would correct this but still need to prove it. I have one of the correction boards and need to look into making it work.Originally posted by Andy.BWhenever I am about to make a particularly questionable decision regarding a worryingly cheap diy solution, I just ask myself, "What would Ether-D do?"

I'm so excited! Too bad I'm still broke. The money gods should start shining their glory down on me soon...Originally posted by Andy.BWhenever I am about to make a particularly questionable decision regarding a worryingly cheap diy solution, I just ask myself, "What would Ether-D do?"

Been reading. There's some dude in Australia, that had accidentally fried his TCU (trans control unit) for his 4hp22eh. Then he just rigged up a rotary switch and some relays to manually/electronically change gears. This fact is making my brain feel all warm n fuzzy. So does this mean I could do some nifty shit with gear changery? Flappy paddles? Something cooler? What may the options be if I manualize (or manualify?) this auto?Originally posted by Andy.BWhenever I am about to make a particularly questionable decision regarding a worryingly cheap diy solution, I just ask myself, "What would Ether-D do?"

Reading more, I find that the TCU will retard ignition timing (during shifting) to smoothen shifts. I like that. I think I really need to make the 4hp22eh work like it did in the 735i. If it shifts all luxuriously, that could still be awesome.
