custom gauges
 

Hey all!

So, after my fiasco with my gauge needle, I considered doing something a bit different. I'm wanting to change out the tach, speedo and fuel gauge with aftermarket, properly sized versions of themselves. I was told, for the most part, the change would be plug and play. However, I'm going to lose my indicators that are present on the tach. This leads to a question. Is there a way to direct the indicator signals to an outside source or to a separate monitor so I can keep track of them easier, should an issue arise? If not, I could always use an obd2 reader at all times, but I'd prefer a cleaner approach.

Any insight into this would be great, especially if you or someone you know has done similar.

Thanks!

Don't expect it to be :twocents:

What gauges you planning on going with?

Have you looked at the Haltech IC7 dash - I used one in my race car last weekend as my logger dash died and have seen one in a Suby Rex road car and they are awesome .... there is a printed carbon bracket that sits neatly under the OEM instrument panel top .... all driven from the OBDII connection for a road car

I'll hunt for a photo of my car from the weekend and post it here if I can find it.

Here is a few pictures of mine! Sébastien at Specialty Z is doing the install. Don't have any final pictures yet.https://uploads.tapatalk-cdn.com/202...1ea394663b.jpghttps://uploads.tapatalk-cdn.com/202...4c0e233b93.jpghttps://uploads.tapatalk-cdn.com/202...416c1f6b7d.jpg

Who said this would be plug and play? Unless that person was talking about a haltech I would expect it to be a royal pain in the ... As far as the indicators go, I believe that they are all sent on the CAN bus in different messages, so if you're really 'bout that life then you can make a device to monitor the bus and do whatever you want when you see the bits in the messages. I'm not sure if the gauge cluster does this or if it has discrete lines for each indicator, but I do know that you can get at them from the CAN bus.

I have considered something like this, but I don't much care for the look. I prefer to keep the original set up but with aftermarket gauges.

Not 100% decided on that part yet. I'd like to get an overall gameplan before taking the plunge with that decision. Anyone with gauges close or dead on the same size that we have stock. They need to be color adjustable or blue though as that's what my interior and accents are.

This is probably an easier route for your goals :twocents:

Speedhut gauges you can custom order. I have the oil pressure, water temp, and diff temp gauges.

I actually wanted to do this immediately after getting the car but waited to save up. Now, with covid, no one around me has time to do it until next year. I'm not horrible per se with soldering, but I'd rather someone that would warranty the part do it.

I have checked them out before. Unfortunately it seems any gauge I want and like doesn't have the night color I'd want. I'll check them out again to see if anything has changed.

Did someone say CAN bus???? That's been my area of research for the last 3 months :)

(Updated with correction)
The turn signal stalk is wired to the BCM.
When the turn signal stalk is signalling a turn, the BCM flashes the external turn signals and broadcasts a CAN message, that is received by the combination meter/gauge cluster which turns on/off the gauge cluster turn signal.

The CAN ID for the turn signal is 0x60D (BCM), second byte, bit 6 for right turn / bit 5 for left turn.

The Haltec is supposed to be plug and play with factory ECU and is what I ordered. I have not talked to Seb about the install yet but I will shortly. Also Austin Hurtle who is on here sparingly but is on Instagram installed one of the AIM dashes and figured out the CAN bus so you may try DM-ing him on Instagram.

I would like to pick your brain about this. I'll send you a PM

Anytime... I enjoyed your posts at RomRaider...

For those that are interested the Haltec dash is a plug and play with the Nissan 370z ECU. It is pretty bad ***. Remember it is not a data logger. Some of the displays on mine include water temp, oil pressure (you have to purchase the sensor separately) and AFRs with left and right displayed separately. I will be spending some time sett up the alarms for things that make the engine go boom!

IIRC he is using the AIM dash alongside the factory dash, which was relocated to another spot in the car (out of sight).

Right on! I guess mine setup the same but different!

Jumping on this thread. I'm currently working on installing my IC7 as a "replacement." The wiring diagram for the gauge cluster shows no specific items for the turn signals or high beams. Still, I remember working with a Torque Pro dev a long time ago, getting the OBD2 to flash the lights and the indicators. An update on the IC7 display showed that the dash has the ability to see the indicators and lights, but it's grayed out for me.

The big oof in the setup is getting the alternator to work. I asked Austin about his setup, and he has the standard cluster mounted under the dash. This would make sense as many of the TC spec cars I've seen are still running the standard dash (tuned with either uprev or ecutek), while many custom builds are using standalone (like the Z1 T/A car).

I imagine this will take a bit to get it working fully, but the upside is that the Haltech dash is a fairly new product. So that has an upside when talking about future updates.

How did you get your AFR display to work? I had a hard time figuring out which wideband to look for lmao.

I have no idea lol! You can email or call Seb. He is good about providing information.

I got the answer, and he did what I thought—Haltech WB dual-channel (super nice).

I have ports in my HFCs to add on sensors, but I'll see if Haltech can use the PIDs I sent them to enable it in the OBD2 protocol. I managed to wire up the Oil Pressure sensor that came with the VLS gauge, and I made a rough CAD drawing of a mounting bracket my buddy would print for me. He wants to try this new carbon fiber filament he has, and it sounds like a good application for it.
