el_bandido Posted October 11, 2018 Share Posted October 11, 2018 Hmmm I'm sure some PC wizadry could make it work with Links or Syvecs Syvecs are the problem which led to SRD moving to a MOTEC on the IS-F. They don't allow custom firmware, so someone at Syvecs has to program the gearbox for you, and only if they want to. You need an ECU with an open protocol.

scott.wild Posted October 12, 2018 Share Posted October 12, 2018 The ZF8hp is used in just about everything at the moment. Just to give you some idea as to why the 8 speed is a vastly better choice than the 7 speed DCT, here is the speed to gear spread on a few options: M3 DCT with Whifbitz custom diff vs NA6 diff and ZF8hp https://jza80.mkivsupra.net/imports/2018/10/1.png M3 DCT with Whifbitz custom diff vs TT6 diff and ZF8hp https://jza80.mkivsupra.net/imports/2018/10/2.png M3 DCT with Whifbitz custom diff vs NA6 diff and IS-F gearbox https://jza80.mkivsupra.net/imports/2018/10/3.png More aggressive through the gears and a higher top speed/lower cruising RPM. Not only will it be faster, it won't cost you so much petrol on a motorway run. Interesting numbers, I was auto and went with the 3.2 rear, would be good to see how the M4 DCT gear ratios stack up and I believe there is little to no tunnel work needed to make it fit.

el_bandido Posted October 13, 2018 Share Posted October 13, 2018 I'm not sure what the ratios are for the M4, I'll see what I can find and plug the numbers in. Quote Link to comment Share on other sites More sharing options...
phobos Posted October 13, 2018 Share Posted October 13, 2018 (edited) I'm not sure what the ratios are for the M4, I'll see what I can find and plug the numbers in. Here you go. Ratios for the F8x M3/M4 are much better. I actually have the box waiting here for Paul to complete the adaption work Edited October 13, 2018 by phobos (see edit history) Quote Link to comment Share on other sites More sharing options...
