I personally know Jason at JSM. Used to be a straight shooter, and I am sure still is.

True that. 2 blenders! Second O2 is just there to tell you the cat is misbehaving I think..... could be wrong.

The trouble with an EGT is that it is less specific about whether there is a timing or fuelling issues causing the variation in temperature. Lambda is more specifically mixture related - well timing can change mixture slightly, but that's another thing. I know there are tables for individual bank trimming in the oak, but certainly with regards to the turbo engine, the function is disabled and the tables are empty. I struggle to see how closed loop individual fuel trimming can work on these engines when it comes out and straight into a blender. It'd be one hell of a task to map that with both O2's downstream as they are.

Not done it on one of these yet, as the provision to 3D trim the cylinders is not there yet, and I dont know if it is even coded into the oak. There is no closed loop individual lambda trimming to the best of my knowledge, but there is individual cylinder knock control. The The last GTR I did which still ran the stock intake went like this: Cyl 6 needs an increase of 6% by 5000 at 200kpa abs and 12% by 8000, but needs a reduction of 16% at 50kpa abs below 3000 tapering to zero by 150kpa abs and 5000rpm Cyl 5 needs a reduction of 12% at 50kpa abs below 3000 tapering to zero by 150kpa abs and 5000rpm Cyl 4 is neutral Cyl 3 needs an increase of 3% by 8000rpm from 5000 at 200kpa Cyl 2 needs 5% by 5000rpm at 200kpa and 9% by 8000 at same pressure Cyl 1 is neutral This sorts the fuelling out. There is still cylinder temperature to deal with, which I use high speed EGT's for.

My R-Spec has the steel pan too.

I went for the Process West V3.2 kit. Cant speak highly enough of the package. Dealing with Kev is always a pleasure and the product is top notch. In my case, it was no direct bolt-in fitment, as various clearancing issues needed resolution, there was no provision for the factory boost guage sensor, I remade the air cond pipe, made my own battery cables etc, the park light globe is not happy as the new style under the headlight cold side piping doesnt seem to sit right and the driving light similarly gets a bit of a belting on the pipe, but it's all part of the process of modding cars!

Thumbs up for individual cylinder tuning! Of all the engines I've tuned with the above in mind, I have never seen a linear variation in cylinders across the rpm and load range.

Without Doubt, go the BIG Process West, but dont expect it to fit without some choppy chop.

I've spent the last 3 months 'reading' this thread from start to finish! Love the 'you cant park there' theme and you can never have enough tattoo'd goodness.

Raise the rear roll centre!!

What rims are they?

That looks familiar!

Good luck, and best wishes.

Who makes the carbon fibre rocker cover garnishes?

Thanks to all. I have actually been adjusting the front toe purely by feel, rather than specification, but was curious to see what it was meant to be.
