theredone Posted September 11, 2015 Share Posted September 11, 2015 I'm looking at converting to a bmw e46 m3 6 speed getrag box I'll be doing this to my 1.5jz build but unsure what I would need to do ecu wise with the 6 speed box any suggestions???

johnny g Posted September 11, 2015 Share Posted September 11, 2015 My first suggestion is a complete run down of what your car has/is. Mods and ECU installed? If it's manual to manual - then probably nothing It it's auto to manual - maybe something? Link to comment Share on other sites More sharing options...
Scott Posted September 11, 2015 Share Posted September 11, 2015 Depends on if the gearbox has a speed sensor. I'm guessing it'll definitely have a reverse switch, but the speed sensor always seems a bit of a catch. Syvecs can get the speed from the wheels if you have ABS so no issues if you have that Link to comment Share on other sites More sharing options...
theredone Posted September 11, 2015 Author Share Posted September 11, 2015 It was originally a auto but I converted it to manual! I have a 1jzgte ecu so far but I wasn't sure if I'd need a standalone for the a bmw 6 speed box Link to comment Share on other sites More sharing options...
theredone Posted September 11, 2015 Author Share Posted September 11, 2015 It's a t74 single turbo build so I'll be looking for around 600hp+ Link to comment Share on other sites More sharing options...
johnny g Posted September 11, 2015 Share Posted September 11, 2015 It's a t74 single turbo build so I'll be looking for around 600hp+ You'll definitely be needing an aftermarket ECU to control the engine. Link to comment Share on other sites More sharing options...
theredone Posted September 11, 2015 Author Share Posted September 11, 2015 Yeah I'll be getting a greedy ultimate but unsure if the 6 speed would work with that and the 1jzgte ecu I have already Link to comment Share on other sites More sharing options...
