New Tuning Advances With Cobb Accessport

Thanks to the master of Cobb Tuning and GTR engine management John Banks the R35 operating system has been re-written yet again over the past few weeks :)

After rewriting the entire boost control code to make the GTR management work properly at higher than stock boost (plus a host of other stuff) it was time to program and 'crack' the launch control in the TCM. Now this has been achieved there are some other cool things on offer that put the factory GTR computer (when tuned with an Accessport) beyond the realm of anything the aftermarket have so far dreamed of for these cars.

The first innovation is using the factory big single boost gauge as a 'Knock Light'. Remember the flashing check engine light on the Power FC? The Cobb Accessport tuned GTR computer can now do this, but even better. Check the demo -

When you see the boost gauge flash its an indication that the GTR knock sensors have been alerted to detonation. The computer then rectifies the ignition timing automatically, but still lets you know its happened.

Then there is the intelligent map switching. Your tuner can write 9 different engine maps into the GTR computer with different boost levels, fuel, timing etc. and you can switch between them on the fly using the cruise control buttons on the steering wheel. Look at it in action here -

The possibilities are absolutely endless and the integration is astounding :)

Exciting times are ours :blink:

Cant wait to test this over the next few weeks! :D

It will be interesting to see what the new HKS V-Pro http://www.skylinesaustralia.com/forums/Hk...ar-t330492.html has to offer in comparison. Is this available in Australia yet Martin?

Cheers

I am not sure about the availability of the F-Con.

What I do know is that nothing compares with programming the native code in the factory computer.

Now the interface between the MFD and the PCM has been cracked I think the public will be able to look forward to some spectacular innovation.

That is just amazing what they're managing to do reverse engineering the OS like that. I can see custom MFD screens on the horizon in the foreseeable future! Run everything including map switching from a custom GUI all controlled via the touch screen! How neat would that be....

And agree fully on using the factory ECU over aftermarket. Why stuff around with all the factory settings that do not need to be changed once you can do everything that you need with the OEM ECU.

I am pushing for that custom GUI but apparently its fairly difficult.......time will tell

9 independent maps at the flick of a switch (Cruise Control buttons) is pretty spectacular for the time being! :)

Real Time tuning is just around the corner as well, being tested currently, all using the on-board RAM in the factory GTR PCM

      Can't you put the pistons to TDC and then do the valve seals? Or will the drop down too far to pull them back up?

      Replacing turbo water line - any recommendations or advice?

      By sunsetR33 · Posted

      One thing I can tell you is, do it properly the first time. If you encounter unexpected problems just let the car sit for a week or two if you have to get some other parts or figure stuff out.  I'd have said go and use as many OEM parts as possible but since you want to change the turbo later on a custom kit is probably the better choice. Since I have no experience with RB25 just compare parts diagrams and images before buying a line kit and it should be easy to see if it has everything you need. Amayama has very good parts diagrams and part number lists, that is what I used a bunch to figure out what I might need. And don't forget to plan ahead and possibly renew other stuff that's easy to get to while you're in there doing the turbo lines. Happy wrenching

      Update 4:   Hi all, good news. Engine is running and all the gaskets and seals seem to be working as intended. No leaks so far, even the JB Weld seems to hold. I flushed out the old coolant a few times and put in fresh coolant, not Nissan stuff, I decided to try the Ravenol Protect FL22, they claim it works for a wide variety of JDM cars and the opinions on it by some people were pretty good. And it has the nice poison green color! And man am I glad I bought a coolant system tester earlier this year, vacuum filling works wonders on this engine. I can definitely recommend this to anyone still doing it the old school way. All you need is compressed air supply. Will have to do a small test drive as soon as I can, I removed the gauge cluster again as the tacho needle was still bouncing around a bit but it was much better than before already.  I also found some cracks on all 4 tires inner and outer sidewalls. Apparently these tires should 't be parked on for extended periods or be kept under 0 degrees during storage, which I did not know. Clearly the previous owner didn't look into those details either, he probably bought them just cause they are cool semi-slicks. I'm just wondering how tf I am supposed to reach 30-80 degree tire temperatures on the public road consistenly, these tires were never going to work for my use case. I'll probably order Continental SportContact7 ones as these are the best allround summer tire available right now and I don't think I'll need anything crazier for now. Do let me know if you have experience with various tires and which ones you recommend.

      Not going to pretend I didn't do a bit of junky work this time around, but mostly due to the fact that some things I am not willing to spend days fixing right now, like wiring. I try to do most things properly the first time around.
