Just installed LC5.......

Well, thanks to Joe and his team of highly trained monkeys I just installed the LC5 TCM update.

Fairly easy process (apart from my eternally flat-ish battery ) which required uninstall of the previous TCM map, followed by reinstalling the LC5.

Now I'm no launch junkie so you'll need to experience that for yourselves but my first impression is...



Mmmm buttery buttery smooth changes in Manual.


Many have said that the LC4 map is the big improvement but take it form me that I can certainly feel a huge difference in change up behaviour from my old LC4.

It is so smooth now that I actually had to check that a higher gear had actually been selected as I didnt feel the change.

Low speed manners is better than LC4 but not as big a difference as prior to LC4.

All in all, thanks must go to Joe and his team at Cobb for yet another free update which continues to make my AP a very cost effective device.

It now means my GTR has been transformed twice in a year into a smooth operator.

Bravo Cobb, and thanks again from a very happy punter (and shame on Nissan for not rolling out this sort of update to all GTR owners).

CC

To uninstall LC4 you have to uninstall the cobb totally and after flash both the ecu and tcm right? Will need a trickle charger for that I reckon.

So LC5 is a download from the 2012 GTR and LC4 is a 2011 ?

When you attach the AP, just go to uninstall and it only removes the TCM map.

You then just select the new TCM map which now shows both LC4 and LC5.

And as far as I know, yes, LC4=2011, LC5 is the new 2012 TCM ROM.


Install it and you'll love it, I do.

Charles,

Did you require a trickle charger for the battery?

I have my LC5 waiting to be loaded but have been told it can take ages and flatten the battery.

Only takes about 15-20 mins start to finish and I had to put mine on charge whilst I did it purely as my 3 year (ish) old battery isnt what it used to be!

My charger is a Halfords one, albeit one of their more clever ones and as soon as I put it on it showed 11.8v and after reflashing it was up to 14.4v. I did of course turn all electrical type things off when flashing.

You only have to uninstall the TCM then reinstall it so nowhere near as long as when you do the original ECU remap.

I also didnt bother downloading the map off the car as the AP already has the map on it.

All credit to Joe and team, LC5 is another step forward for the GT-R.
Manual is smooth and rapid as Charles describes and auto is also significantly improved; holding third a little longer when accelerating and driving in 30/40MPH built up areas, so less 'hunting' round the box when you touch the accelerator.
Gear change points seem much more suited to our roads, almost like it has been optimised for UK.

Transmission R-mode in auto is completely transformed. As Ben mentioned it now holds the gears much longer during acceleration and blips the throttle as per manual R-mode on downshifts, much better and more fun.

Exactly.
Nissan need to catch a wake up call. It should be the HPC's that offer this upgrade during one of our frequent services.

I'd definitely use a charger.
I fully reconditioned/recharged my battery less than a month ago and the CTEK showed it only at quarter capacity when I put it on charge on Thursday.

Cheers for the feedback guys

Don't worry fast flash tcm switches coming, but most will want to keep on LC5 now

Very nice update, my thoughts.

Does indeed make the AccessPort a very cost effective buy
