To save damage to the gearbox, the GCU has to be closed loop control!
If not, you're either wasting time or going to miss shift.
The better systems will protect your gearbox and engine from over revving by mapping each gear with the ratio and throw distance/timing/pressure which is different for each gear. Takes a long time to configure but clutchless up and down gear changes are possible, even at low speed.
I use the shiftec system but as its used in Le Mans etc as standard, it's definitely the best system but unfortunately not the cheapest; they even do the clutch system to go with it to make the car true F1 2 peddle setup...
Also, GCU is canbus and can talk to Motec etc which then allows the ECU to know what gear youre in which opens up further features.
I'm after a set of bonnet damper for my R34 GT-R.

I have emailed AEM but no response as yet. Basically the wideband gauge is going into heat cycle as I turn it on, this is normal but what should happen is it reads AFR. The issue is, now for some reason it stays on a heat cycle, displays “LS4.9” after about a minute then goes straight back...
never had this issue before, but last two times I've driven it, keep on getting the car cutting out, has happened mostly when in traffic or low speed.
will be driving along, and you can just all of a sudden feel power loss, no amount of pressing the accelerator will do anything, just have to...
I've readed many post for Single Throttle vs Multi Itb.
But, who has done a DBW conversion on both?
What parts are needed to keep the Multi ITB For a DBW conversion?
I think that is easier on a Single throttle.
