DON'T Tune Your Nissan GT-R Transmission!

[@E92M3]

Dual clutches arn't designed to go back into first gear unless at a complete stop. Every dual clutch system is the same in that sense

[@madgainz7871]

Agreef, same thing on my RS3

[@Marco_Siegert]

Everyone who ever drove a dual clutch car knows that, you are just right. Its the same on my S4.

[@shutterfish]

agree👍

[@fxvela]

I been using this TCM tune for 4 months and is working great. It has a LC setting that let you change the LC RMP. It works great.

[@davidnaumann8086]

I used to use COBB and had issues with the maps shifting gears way to early in the powerband in A mode. I typically drive in manual most of the time with the exception of being in bumper to bumper traffic. 1st gear for me is insanely twitchy and pretty much useless because I have to up shift so quick or risk slamming into the car in front. Upgraded fuel system to run E85 and switched to ECUTEK. Software is better, more features and the bluetooth dongle with the IPAD app really adds tune ability and ease of use. Its harder to find ECUTEK tuners but I like it better in that I feel I have more control and can see exactly whats going on with my GTR on the ipad app. 2013 Alpha 9 GTR w\shep 1K. 900WHP

[@kageryu311]

Right on the money.

[@sc0llay]

The Stock style LC5 is for 2012+ cars that came with factory R-Mode start and launch with RRR, the LC5 VDC off is for CBA cars as they need the VDC off to launch on that software

[@tjlazer71]

You want to put the LC5 VDC OFF Optimized map on. Allows you to launch in VDC OFF if you want, but the main benefit is optimized shifting in auto mode. No 60mph in 4th gear cruising around. If you mainly drive in manual mode, then this tune is not needed.

[@Mikey6048]

Got my 2014 Tuesday. And drove it back 15 hours straight. This cars transmission is the most bizarre sounding and operating at low speeds. You are so right how clunky 1st gear is. I'll have to give this a try.

[@BrosFOURRSpeed]

Yup!! Such a weird transmission and it sounds like it breaking most of the time. I still own this car and am now FBO on E85. I have a bunch of new videos on the GTR! And have one coming going over the cost of all the mods and tuning the transmission now that it's on E85. I've learned a lot since this video ;)

[@Mikey6048]

@@BrosFOURRSpeed I'll keep an eye on it, I keep bouncing between all your GT-R videos. My GTR is FBO E85, so all the fun of installing is pretty much done already. But I am going to replace most of it with AMS Alpha components to make it a Alpha 7. I'll be posting videos on my channel soon. Keep up the great work, and it's nice to see another content creator who talks to his viewers.

[@thedarkknight7924]

From the Cobb site. I have a 09 with a 14 transmission. I'm using the optimized v100 for the 38B0B, i used Accesstuner to modify the shift mph values.

[@sswes2476]

The tune in my Camaro worked amazing I got fith gen auto it made the shifts way faster and the bang harder.

[@craigg8394]

Mate I'm on ECUTEK and my transmission shifts at under 2000rpm 1st gear shifts at around 1800rpm all the rest of the gears shift at around 1500rpm.5th gear to 6th in auto mode shifts at 34mph.The car feels fine crusing around with its shifting this early even at 34mph in 6th gear.From 2nd to first it will shift down to first at 4mph.This is all with the accelerator lightly pressing crusing around.

[@RevToRedline]

Jotech in Texas is the way to go my friend. IDK where you ljve but they're one of the top shops in the U.S for GTR's. I'm going there next month for a tune 😊

[@shutterfish]

That problem is very common with dualclutch. Had a soccermom Kia Carens that hade similar issues with the trans in auto

[@BrosFOURRSpeed]

Oh wow, I just had to look that car up lol, never heard of it. Looks like the Rhondo version for out of the states.

[@Pdossou32]

Just like some the comments I’ve seen. My Infiniti QX70s does that as well. At one point I thought their was a problem it’s that bad. That’s my big gripe. Good to know I’m not imagining this. Trying to find a solution

[@pfizzle1]

Ecutek has a better tcm tune. Ultimately you can run cobb for ecu and ecutek for tcm

[@javon6604]

The DCT in my M3 does the same thing. It’s the main reason I’m never buying a DCT again unless it’s a PDK

[@videomaniac108]

This is one of the reasons that I will not get an automatic, another unnecessary problem with which to deal. The 6M in my 2019 370Z sport coupe works fine and even the SRM works nicely, although I rarely use it. Having developed the touch and coordination for heel-toe rev matching over years of driving, I am able to do fast and smooth upshfts and downshifts into any gear for whatever the driving requirement is on the road. Sometimes less is more.

[@Masterballsackwood]

You'll never beat 150ms shifts though

[@vegafiedmedia]

Drive a GTR for a week, tell me you hate it and then I'd believe your "unnecessary" comment. MANUAL MODE eliminates any 2nd gear to 1st gear issue referenced in this video... My GTR rev matches into 1st like butter. There's a reason why Indy cars do not have the 3rd pedal. it becomes "unnecessary to have due to torque loss, Miss Shifts, one hand off the wheel, shifting speed, etc... So in reality, a 3rd pedal is not efficient and becoming unnecessary. Hence why 99% of the Super/Hyper cars have Dual Clutch systems.

[@pdxfamily4733]

With my OCD that would drive me nuts

[@LRS7B]

Perfectly normal for normal cars to pull off in second gear, let alone *500+ BHP* cars

[@edinlasers416]

He’s no where near 500

[@hamsandwhich3378]

Honestly imo ditch cobb like I did for ecutek miles better especially the trans, I daily my GTr with FBO + upgrade turbos and it drives like oem, little bit harsher shifts because the clutch capacities were turned up to prevent the clutch slip from stock eng/stock trans

[@BrosFOURRSpeed]

ECUtek is owned by the same company Cobb is. And the same tuner can use each software and get the cars performing identically. I now have an update tune on my transmission for my E85 setup and it's been perfect. All comes down to your tuner and settings. I have my capacitors at +4 for normal driving and +7 for launches.

[@gtr_guy]

That’s just dual clutch cars. My S4 does the same thing with the stock tune and with the 034 Motorsport TCU tune.

[@BrosFOURRSpeed]

Yeah I've messed with the transmission tuning later on but still prefer the stock style shift maps for this car. Now on E85 I adjusted the clutch capacitors to be able to handle it. So it's useful

[@gtr_guy]

@@BrosFOURRSpeed I’m just now catching up on all of your videos. I’m currently in the market and want to see what everyone is doing over the years with the tuning and such. I’m use to Audi’s where is simple to tune. Still learning how the Cobb access works.

[@BrosFOURRSpeed]

@@gtr_guy Oh cool! I just hit 4 years with it. Absolutely love the car and it's been a great ownership so far! I have really liked how easy the Cobb is. I had EcuTek on my Supra and having to use a Windows Computer wasn't that fun when I needed to update a tune.

[@caseyzecca481]

I am looking at a 2016 nismo and would really appreciate if u could take a look at a short clip I have of the car accelerating, it has a weird, what seems like clutch slip or something.. maybe u would know could I dm you this video?

[@kageryu311]

Ecutek is FAR better for the TCM. Off the shelf tunes in general are terrible. The title of your video is clickbait.

[@smanders-smanders]

I always drive my GT-R in manual mode as well as RNR. I have a TCM tune via Ben Linney - EcuTek. Auto mode is ALWAYS too annoying for me....TCM tune or not.

[@BrosFOURRSpeed]

Yeah I'm in manual RCR most of the time too. I'm going to try another TCM tune to see how it is. But I'm not really seeing the benefits.

[@kageryu311]

@@BrosFOURRSpeed Auto mode in the GT-R isn't great.

[@borinpich7420]

Is there a way to reset the transmission fault code?

[@BrosFOURRSpeed]

The Cobb should be able to do that. Later on when I did E85 I did do some tunes for the transmission and was able to make adjustments to handle the power. So this actually was very useful. kzbin.info/www/bejne/hqayopaspLZ9eMk

[@betbeast9372]

why not just use the paddle and shift yourself problem solved or am i wrong?

[@vegafiedmedia]

Being in auto mode is great for heavy traffic and coffee sipping on the way to work (I daily mine). the CBA's benefit more from the Cobb TCM tune since it gives you LC4/LC5 option. before my tune, I absolutely hated being in Auto mode with the LC2 stock Tranny setup. Shifting into 6th at 35mph is not my cup of tea.

[@oreally8605]

You could always ask your speed shop for information

[@BrosFOURRSpeed]

True. But I perfectly fine with the stock transmission tuning. When I do some custom ECU tuning I'll see if they have any recommendations if there are good ways to tune the trans

[@gtr.alex_m2959]

the car isn't just shifting at higher rpm its adjusting transmission pressure to shift more aggressively when under load. If you understood more about modifying your car beyond a ots tune, such as fbo e85 to start you'd realize that your info is so wrong and your mods are nonexistent

[@kageryu311]

Also Saying not to do the TCM tune in any GT-R is bad advice. Just because you used a crappy Cobb OTS tune doesn't mean that getting a Cutstom LC tune works. Also Cobb is trash. Ecutek is far superior.

[@Z34ZMONSTER]

You need to go to Soho Motorsports, they tune GTRs now with ECUTEK!

[@craigg8394]

ECUTEK is the way forward

[@mreddy9]

Looks like you were running LC5 already alot of owners like Lc4 better i have a 2010 i probably have lc2 it will be a night and day difference for me when I get my cobb but you can try other maps from the website that you don’t see in the cobb currently maybe those will work better

Wouldn't shifting into first gear without being at a complete stop..damage the transmission??

[@puny-tinsucks5102]

it shouldn't unless you were doing more than 5+ mph.

[@fxvela]

Hi, I have a 2016 BE with 6500 miles and just got the AP and so far I have not have the time to install it. I did not get which TCM file you used. Did you try the 80B0A VDC OFF G2-LC3 OPTIMIZED SHIFTING TCM file? That is the one my tuner recomended for my application. He said that with that tune I’ll able to selected launch RPMs for that one launch. I would like to launch at 3,500 RPMs not at 4,100. My car only has a HKS mid pide, AMS Fuel Cooler & know the AP. Tomorrow I’ll installing the AP. Let see how it goes. Saludos from Puerto Rico🇵🇷

[@BrosFOURRSpeed]

I tried a few TCM tunes. One of them kept saying 'locked'. But I can still set the launch control RPM. The ECU tune is fantastic. It will really wake up the car!

[@fxvela]

Bros FOURR Speed , Last Friday I flashed the Stage 1 and TCM Optimum Shifting Tune and sobfarcso good. With little mods it has the car ended up with 518whp bit for some reason was giving a peak whp of 570 at 6900 to 7200 rpms. The TCM tune worked fine but there is very little difference from stock. I did not have the time to look for the LC RPM parameter. I will look for it and let you know. Saludos.

[@rickyohh9330]

It’s suppose to keep you in optimal gear for power it’s not a Prius 🤦🏻‍♂️🤦🏻‍♂️

[@BrosFOURRSpeed]

Its way too aggressive for daily driving. When I put the trans in the R mode, it already does that. So why would I want a tune that makes the normal driving mode as aggressive as R mode

[@vegafiedmedia]

​@@BrosFOURRSpeed R mode in Auto still goes to 6th gear at 35mph on the 2010's. I think the cars that get the most benefit of these TCM tunes are CBA's. In my Cobb tune I have LC4 installed and its great. Before the LC4 tune, I absolutely hated being in Auto mode. The thing is, everyones definition of "comfortable daily driving" is different.

[@twelvecars9297]

I got a 2010 but I got use to just stopping then going. It's annoying but I didn't get it for convenience.

[@BrosFOURRSpeed]

Yeah thats what I end up doing

[@leesanchezz]

Same with mine.. did ever find a good TCM map?

[@BrosFOURRSpeed]

I never had good luck with the Cobb ones. All seems way to aggressive. But eventually I'll be doing custom tuning with ECUtek and that should do a good job making the trans perfect

[@leesanchezz]

Yea. Mike from AAM asked me to get it. When my adjustable exhaust and fmic gets installed I think I will need it for a tune. We’ll see..

[@BrosFOURRSpeed]

There was another tune that was on their website that I tried. But it said locked. So hopefully I can get that one to work and see if it is better than the ones I tried and better than stock

I literally just took out my GTR to see what y’all talking about I was doing maybe 60 in 6 floored it full throttle it dropped from 4-2 then back up? Kind of rainy tonight so second traction came on but it didn’t slide hmm. I’m going to try it on the highway tomorrow and time it. Also mines shifts to 1st at 6mph definitely not 3mph closer to about 5.5 ish. Car is stock had it about 3.5 years never tuned to my knowledge. Personally I hate going slow in this car the same way I hate going slow on a liter bike. It’s like they ignored first gear and just said oh we know it’s trash just launch it though and you’ll be fine it says it in the manual to expect weird sounds like wow really debating the Nismo instead of FBO E85 my 2014.
