Gtr Transmission Tuning Cracked

[Martin Donnon]

Some of you would realise that we are on the Alpha test program for Cobb Tuning, and as such we get input into and then early testing rights on their latest R35 GTR software releases. Well after some weeks and months of coding and testing, here it is, an early glimpse at the software that will eventually allow you to fully customise the launch control settings in your R35 GTR. Have LC1? Then Upgrade to LC2 or LC3. Want to go the other way? No problem!

There is also the facility to custom tune the Launch rpm and alter a multitude of temperature breaks in the transmission which in turn de-rate engine power with an ECM request

There are also handy features for the casual user such as being able to perform a live gear re-learn and also adjust full Clutch Capacity and Touch Points to alter shift timing and pressure application. This is a serious breakthrough for the R35 GTR community, make no mistake about it

interesting. so the GTR will cut power / torque based on tranny temps? how does it do that, timing adjustment?

[Martin Donnon]

Torque reduction is via various strategies depending on the severity. Normally timing retard, boost clip, throttle clip, depending on how it is requested. In the case of the TCM its normally via throttle in my experience (ie. limiting actual throttle angle versus requested)

Wonder if we will see some broken gearboxs once people start messing around with gearbox settings. I would think it could prove dangerous in the hands of the inexperianced. But will no doubt transform the car in the hands of people at the forefront (Martin). As it seems that the gearbox is what makes the standard GTR so good but is also seems to be the achelies heel of the more modified GTR's should be some interesting times ahead.

great!!

How long do you expect before its available to us?

Will it work with the stock Cobb tuners we have?

It will be great to see a R35 with 9krpm launch one day when (and if) OS Giken or Holinger will make gearbox components for the gr6
