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 :P

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 :angry:

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) :cool:

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.

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

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
