Discussion from another thread.[quote name='zidee;626254]Haiya how my steering nak laku like this. Everyone talking about SMG now..he he. Have to put on eBay I guess.p/s Since we are talking about SMG' date=' another project that me and Haywire is exploring is to re-look into wiring where we do not have have to push our gear stick to S position (+-) to engage the Sport mode. Just simultaneously tap both + and - paddle to engage and dis engage the mode. Anyone out there has done it please share the wiring diagram as i know it has been done out there.[/QUOTE'] [quote name='Ade;626510]u will need to disconnect 3 wires from the steptronic gear and connect it to a microcontroller together with the + and - lines from the paddleshifts. You will need to program the microcontroller to recognize that when both + and - is being engaged means to go into sport mode and the microcontroller will trigger a ground on one of the lines. Have not done anything for this to happen but i think its possible as I've tried manually grounding one of the wires (can't remember which color) and the car recognizes it to go into sport mode.[/QUOTE] [QUOTE=aidilj;626513]Ade' date=' sounds very doable, will be system be ok when both of the inputs are both pulled low to exit sports mode? One or the other mustve take priority. If the shifting logic can handle this already, this can be done with just some relay/transistor, no need for microcontroller.Bro zidee, you highjacked your own thread with SMG discussion..[/QUOTE'] [quote name='Ade;626523]From what i gather is this' date=' 3 wires, 1st wire ground for x milliseconds to upshift, 2nd wire ground x milliseconds to downshift and 3rd wire ground permanent to engage sport mode. The problem is to mirror the 3rd wire permanent ground by flipping the + and - and disengaging that by flipping both + and - again. Perhaps its do-able using transistors and maybe flip-flops, no need to get the bulky relays but I have not thought about the logics to make the transistors work.[/QUOTE'] [quote name='aidilj;626525]Probably a JK FF (7476) will do the trick along with a MOSFET. This mod is doable it seems with glue logic.Based on your info I can cook something up 2moro..</p></blockquote><p>[/QUOTE]</p>
