Litchfield TCM tune

Hi all

I recently contacted Litchfields to get their stage 1 tune. The car is a 2017 Track Edition which I take to the track once every 3 months and go on many spirited drives.

I'm not after huge power gains as I haven't got close to exploiting stock power. (I believe a stage 1 is close to stock nismo power but with more torque, which would be enough for me).

I'm more interested in the TCM tuning and how it differs from stock. What is exactly done. Any feedback from owners who track their car with a Litchfield TCM tune would be much appreciated.

I believe instead of cutting the power it just sends the power to the wheels with max grip though I may be wrong. I do not track mine but you can feel the difference in how it's feeding the power in. My car is on the version 5 software though which is not the latest

I'm looking forward to getting it done. I'll ask the tuner to shed some light on it. Good info on engine gains but not so much on tcm

Would you post your graphs after the engine time too please?

What year is your car?

The very early GTRs when in auto mode were not great around town. You would get the car down to a virtual stop and it wouldn't know if you should be in 1st or 2nd. More often it would be 2nd and would be a bit jumpy.

So the newer TCM Roms & got rid of these issues.

They also mainly improve the driveability. And also how th the cltuches etc work and engage/disengage if you do up the power

Many other things but I cant remember off the top of my head

Found the info I was after. Varying throttle and torque, so going around corners can be made smoother and faster.
In R mode when torque hits, the back can come out easily when going around a bend when throttle applied too early. Woukd be good to reduce this

get yourself an ecutek dongle, stick it in and play with the traction settings.

I do it often, it also has a rain mode, and you have a 'sliding scale' for traction, from 'min slip' to 'max slip'
obviously the latter if you have huge balls
or the prior if you're gay.
i find somewhere in the middle is best.
But remember this is only engaged when you turn the NISSAN traction control into the OFF position.
In the R position it is still nissan TCM, in OFF it is litcho TCM with the sliding scale...

Not quite, this is the LTC and is on in maps 97/98/99 and is on regardless of the VDC button setting, it kicks in before the Nissan TCM, it won't save you from extreme measures and the native TCM will still kick in trying to save, but the limits with mass/speed and physics Makes more sense having it in R mode as it gives you the max slip before VDC kicks in.

LTC is disabled in map100 and if you also turn off VDC, then its ALL off no traction saving grace at all.
