G37 Gear Position Indicator using Factory Gauges (Plug+Play!): MotorvateDIY Garage Ep.46 

Your comment made my day.. Thank you!

I'm working on it.... So far the testing has gone very well, no issues. I am going to a VQ car show on Sunday, and hope to test on many different versions of the V36 G35/G37... Hang in there!

Thanks Isaac G! I will be doing local testing this spring. It has worked perfectly in my car, so I don't expect any problem, but you don't know until you test!

Thanks for your support! I have already shot video for MAF cleaning, spark plug replacement, front rotor replacement, coolant replacement, sunroof drain replacement, 3 year diff bushing update and K&N panel filter update.... all waiting to be edited. So... they are in progress, but will take some time to get out. PS Thanks for subbing!!

@@MotorvateDIY awesome i look forward to seeing those!!

I think the G37 product strategy was more focused on "sport luxury" and the "sport" items didn't make it.

I see the argument for it being a sport feature but I kinda saw it as a luxury feature too. Probably not the best example of it but the BMW M cars have it. But I guess they have a stronger emphasis on sportiness than Infiniti

Thank you for your kind words! I do my best to share progress on instragram, twitter, reddit, facebook, g37 forums and on RU-vid.

Thanks Storm! Testing is going well. No one who drives a standard transmission needs to know what gear they are in, BUT I sure like seeing on the factory gauge!!

Well sign me up I need 3!

I will add you to the "interested" list to remind me to contact you when testing is done. :)

Thanks for the comment! I have added you to the "interested" list. Once I have been able to test on multiple G37, I will let you know :)

Yes there is! Over the winter I updated the firmware to allow for different differential ratios and a few minor programming updates. Testing on my G37 has gone well. In the spring, I'll start local testing to flush out any issues with other models of manual G37 vehicles.

Hmmm, good question. Without knowing the details of how you did the swap, I think it would work. Do you have to push the clutch to the floor to start the car?

Glad you liked it. In the next few weeks, I will be testing it on different versions and year G37, just to make sure it works :)

Thank you!... In my eyes, the video is kind of crappy, but gets the message out :)

Thanks for your interest! I want to test on a few different models of the G37 to make sure Infiniti didn't change the data on the CAN bus. I hope to have that done on June 13 at a local car show and then I will post a video here saying that it is now available... or you can also find me on Facebook: Frank Motorvate, Insta: motovatediy and twitter @MotorvateGarage

Wow... that isn't an easy mod.. good luck!

Hmm... based on what I have seen, I think it will work. I do hope to test on a 07-08 (aka V36 platform) G35 locally in Toronto. I will add you to the "interested" list. :)

Hey Derek, You are correct... I have been working on trying to get the GTR gauges to display on the G37 LCD screen.... I think I am close, but not there just yet. Also, every time I drive my G37, I am testing the LCD mini-dash and manual gear position indicator. So far, it is working well :)

@@MotorvateDIY love the video can’t wait to see the next update. Do you think digital dash is possible?

I do. However, the larger the display, the processing and data bandwidth is required. This is when it gets expensive and more complex. My mini-dash / LCD gauges uses modules that are inexpensive and easy to obtain, but the screen size is limited to around 320 x 240 pixels in order to have a fast responding display. (about 30 updates per second)

Hey Corey, Every time I drive my G37, I test my gauges. Overall, they are working really well! The only issue is about once every 30 starts, the gauge gets stuck in a reboot loop. It restarts over and over. BUT a single push on the reset button, always gets the gauges to start up with out any problems. As you can imagine, this is a tricky one to trouble shoot. My next step is to hook up a debugger and watch the start up.

@@MotorvateDIY thank you for the update, I'm trying to hold out to get your system to constantly measure my oil pressure and other vitals

I understand... Oil pressure is the gauge I have displayed the most. It is very satisfying to have 100C / 212F oil temp and 18 psi at idle :)

I really don't know. My G is a 6 speed manual and I only have a few minutes of seat time in an automatic G.

I believe that was true on the G35/350 with the VQ35HR engine. However, on the G37/370, the valve cover gasket is is available separately: www.z1motorsports.com/cylinder-head-and-valve-cover/nissan/oem-370z-g37-q50-q60-valve-cover-gasket-vq37vhr-p-8879.html

Great question... right now I hope to have a bunch ready for the spring of 2023. The testing I have done so far has been good, but I do need to improve the power management when the engine is off, which is underway right now :)

Yes, it should work and I will be able to test this next month to double check.

There are 2 ways to do this: (1) Fix the TPMS problem. You may have one or more dead TPMS sensors or they may not be programmed to your car. (2) Temporary fix: Use a scan tool to clear the codes on the BCM. This will turn off the TPMS light for 15 minutes to a few days. As you can see, option 2 really isn't very good, so option 1 is the best and permanent fix.

@@MotorvateDIY much much appreciated for your reply, thanks a lot

Thanks for the offer, but since I am not a licensed mechanic, I only work on family vehicles and my own.

The sunroof drains don't need to be clogged to leak. Over time the sunroof drain gasket compresses and allows water to drip and collect inside the car. This is exactly what happened to my 2011 G37... replacement sunroof drains fixed the problem.

@@MotorvateDIY how do I actually know if I need to replace the sunroof drain ?

You can remove the glove box and far right vent, then reach under the dash pull back the insulation to see the drain going into the firewall. With the sunroof open, pour a cup of water on the front right side and see if the drain drips. Watch some videos to get a better idea of what is involved.

Correct, this is for the US/Canada market manual 6 speed G37 Isn't your G35 an automatic?

@@MotorvateDIY now I own g37x 7AT

Got it... This is for the 6 speed manual transmission, which doesn't have a factory gear position indicator. As you know, the automatics do have a manual mode and can select when to go up or down a gear.

@@MotorvateDIY got it Thank you sir

I hope to offer them for sale by late spring early summer. I want to do additional testing on different versions/years of the G37S. I have tested it on my 2011 G37S and on a 2008 G35, everything works as expected. :) Ideally, I would like to test it on a local (Toronto) 2007 G35S, 2008 G37 Coupe, From what I have seen on Nissan's CAN bus, it should work, but I want to verify. After all, if I am selling something, I should know what it works on. Testing them allow me to verify Nissan/Infiniti didn't change the data encoding on the CAN bus. When they are ready, I will announce it here, FaceBook (Frank Motorvate), Reddit (MotorvateDIY) and on myg37.com forum (MotorvateDIY) Thanks for you interest!!

@@MotorvateDIY understable, Mines a 2013 G37S 6MT Sedan, so probably the newest and the unicorn. I’m in NY so if you need anything tested let me know, I also have a 03 G35S if needed to test that as well

Thanks for the offer, I will keep that in mind! As for the 03 G35, the gear position indicator won't work. The required data isn't on the CAN bus and the six speed manual gauge cluster doesn't have the area to display the gear. (autos and manuals have different clusters)

Soon... I want to test this on other G37s, just in case Infiniti changed something. I have added you to my "interested" list :) Thanks for your interest!

@@MotorvateDIY thank you so much

a quick question do you have videos changing hoses on the g37s

Sorry, but I don't. I'm still on the original hoses :)

Soon!! It has work perfectly on my G37 for the last 6 months. My next step is to test on a few local cars, to make sure it works with the different option packages available for the G37. When all is ready and proven, I'll post a video here and announce it on the G37 related forums/social media. Thanks for your patience!!

@@MotorvateDIY I'm interested! Will watch with excitement

Thanks for asking! The price will be around $60-70. The testing has been going well, BUT I do need to add better power management when the car is off.

@@MotorvateDIY ok is it for sale

When can I order

It will be for sale after the power management update and more testing. I will post a video when it is ready to go! Just to be clear: This only works on the G37 with a manual transmission.

Good news! Testing has gone very well and I should be receiving the circuit boards from manufacturing later this week! I'll have a video update shortly after I receive the boards. Hang in there!

Thanks for your interest and I have added you to the "interested" list. What year is your G37? On the weekend, I will be testing it on some other G37 to verify they work on other years.

@@MotorvateDIY Thank you! It’s a 2011 6m coupe. Looking forward to watching your progress

I've added you to my "interested list" My next step to to test on different version of the G37 so I can verify all is good :) This will take a bit of time to organize and execute, but I'm working on it :)

I've added you! Thank you for your interest!

Hey Erick, Overall, it is working very well! I do need to add some power management to reduce power consumption when left plugged in the car for long periods - I'm worried it may drain the battery. It is on my list of things to do :)

Lol.... why not?

I understand :) To be honest, I do like seeing the current gear that I am in the dash :)
