Another $0.02: I believe that incrementing the mileage on the stock cluster is as simple as sending it CAN messages at 10 Hz which contain a high value for the speed byte (0xFF) and waiting for it to count up (as if it were on a running car) to the mileage that the car is actually at.

CAN messages can be sent to the gauge cluster either with an external CAN device or with the Lotus ECU; if one sends the OBD command for mode 0x2F PID 0x126 to the lotus ECU, the ECU will send a speed value to the gauge cluster from calibration memory (I'm not sure if the this will actually increment the odometer, though).

I'm also quite leery about intentionally adjusting the odometer reading so I have not tried this myself.

@ulao, it is surprisingly simple to install despite the videos that are split up into like 30 x 45 second segments with the camera shaking everywhere. It boils down to the following:

0) Disconnect battery
1) Remove screws from lower steering column cowling
2) Remove upper and lower steering column cowling
3) Remove the binnacle assembly (upper and lower)
4) Remove the 4 screws that hold in the stock gauge cluster assembly
5) Unplug the two wiring clusters from the back of the OEM gauge cluster
6) Remove OEM gauge cluster from assembly / housing
7) [For S2 Toyota only (AFAIK)] Splice the red, blue, and orange wires from the stock connector into the provided adapter (just match the colors)
8) Plug in the adapter to stock connector and into the back of the new LCD gauge, also connect the USB connector to the back of the LCD
9) Reconnect battery and ensure everything is working correctly.
9.1) If you are not getting RPM / speed readings check the red / blue cables you spliced in
9.2) If you are not getting blinkers and other readings, check the orange cable you spliced in
10) Attach the new LCD to the old gauge cluster housing / assembly
11) Reinstall the gauge cluster assembly with your new LCD screen
12) Route the USB cables somewhere accessible (I put mine right under the steering wheel and have flush mount USB ports on this part)
13) Reinstall the upper and lower binnacle assembly
14) Reinstall the upper and lower steering column cowling
15) Set your mileage by going to advanced options on screen 4 then go to screen 9 to input the mileage (in km)
16) You're done

Warning....
If you are curious like I am and decide to play around the config and see what other platforms look like.
There is a platform called "SCSD" . DO NOT SELECT. Again,... DO NOT SELECT.
This will lock your screen in a state that will not allow you to do anything else.
It took me a couple of days working with Alec on resolving this and still working on it.

lps2, yes great info but again, in a forum that people need to dig up. Now we have two running threads on the topic. This info needs to be on the original post (this one or the other one). This was my point.

I'm not insinuating that is your responsibility, just defending my point. And, I do thank you for the input.

On a second path here, I'd like to get a list like this hammered out. So let me ask, does this check list talk about the wifi dongle and camera set up? I assume both are a matter of plugging them in. Should we add another line between 9 and 10.

Attach the usb dongle if desired
Attach Camera if desired (follow pin-out as indicated).

and maybe a note section
*** If you plan to experiment do not select the platform called "SCSD"

I think it would be helpful to also include what additional gauges will work or how to set them up. I have the car apart enough to add oil pressure/temp but not exactly sure how to program those with the dash. As it is, those two gauges on the race screen just have zero values. I know where the settings are for additional inputs but not sure where to start with parameters or what sensor will work best.

Great Checklist Lps2! Thank you for laying it out there so that we can understand. Now the debate is whether or not to wait around for Garw's to get another batch of these out for shipment (and pay the higher price vs doing display and needle mods for much cheaper) or to take on the cluster modification project personally.

Ulao, you make a good point that there are other threads out there that already address this topic which is true and is why I debated about starting the conversation all over again. I guess, after spending several nights going through the thousands of posts, I almost came to the conclusion that it would just be better to do nothing at all. There is so much information out there and so much of it is dated (7 to 10 years old)..... it made my head swim. Terry (t955152) put together a great tutorial on how to do a do-it-yourself cluster modification but his post is over 3 years old now. I can't get his pictures to work and his links are mostly outdated. I was hoping that this thread would kick-start the topic again with whatever the latest technology is, including links from people that have successfully done this that show where we can go to buy what we need to make it happen.

Obviously, the easiest thing to do is the LCD unit from Garw and plug it in but I don't want to backorder it and have it show up in June only to have installation problems and then end up with downtime that I can't drive the car just as the weather is getting super nice.

I sent an email to Garw to see what their availability time is on the LCD screen. I'll post something here if I get a reply.

In the meantime, if anyone has a checklist for a current do-it-yourself instrument cluster modification feel free to post them here (and on Terry's thread) so we can get this figured out.

Just got an email from Garw, saying pre-order in 2 weeks, delivery in 6 weeks.

Oh, and another thanks to lps2 on the checklist.

Glockman02, would you take the initiative in putting all this info on the original post in this thread? The entire idea here is to save people the searching. Why not make a quick guide section (crediting the sources) up top?

Anyone have a picture or diagram that explained what this stuff means?

3) Remove the binnacle assembly (upper and lower)

I have the bottom half off and there is no clear way to get the dash out. Google has many videos on the s1 nothing for the s2. Sort of stuck here for now. I see some arm like thing coming down but they do not seem to be attached to anything dash related. I'd be ok if I have a video (even if its bad) to see what parts come out but I'm no longer able to find the videos for s2. I was certain there were a few out there.

. My original plastic one was in two pieces, the top cover and then the piece with 4 clips - my CF one is all one piece and it looks like the guy in the video is in one piece as well

--updated my own questions per Garw.
Ok question 2. Connections? I'm guessing I was not given the wire guide. At least I hope Garw includes this? Looking for info on .

1) what are the 2 usb ports for? One for camera , another for dongle.
2) Where are the camera wires? None use usb.
3) 2s 05 connector has a orange, blue and red wire, what might these be, camera wires?
---found this - "Splice the red, blue, and orange wires from the stock connector into the provided adapter (just match the colors)"
4) The connector with the usb has 17 black wires, any idea what for? Extra advanced features ask Garw.
5) will one of the usb connectors accept a usb cam for RVC? yes



So decided to connect it up anyways to test and the unit does not come on. Tried my old ICP and works fine. Fortunately garw is quick to answer emails. Working with him to resolve this now. -- Looks to be bad.



MY additions would be.

0) Disconnect battery
1) Remove screws from lower steering column cowling
2) Remove upper and lower steering column cowling (the top piece takes work,
)
3) Remove the binnacle assembly (upper and lower)
4) Remove the 4 screws that hold in the stock gauge cluster assembly
5) Unplug the two wiring clusters from the back of the OEM gauge cluster
6) Remove OEM gauge cluster from assembly / housing
7) [For S2 Toyota only (AFAIK)] Splice the red, blue, and orange wires from the stock connector into the provided adapter (just match the colors)
8) plug the wire harness supplied with the kit to the back of the new dash. Plug the udb dnlge in to one of the usb cables and a camera to the other is you wish.
9) Reconnect battery and ensure everything is working correctly.
9.1) If you are not getting RPM / speed readings check the red / blue cables you spliced in
9.2) If you are not getting blinkers and other readings, check the orange cable you spliced in
10) Attach the new LCD to the old gauge cluster housing / assembly
11) Reinstall the gauge cluster assembly with your new LCD screen
12) Route the USB cables somewhere accessible (I put mine right under the steering wheel and have flush mount USB ports on this part)
13) Reinstall the upper and lower binnacle assembly
14) Reinstall the upper and lower steering column cowling
15) Set your mileage by going to advanced options on screen 4 then go to screen 9 to input the mileage (in km)
16) You're done

I decided to bag the idea of rebuilding my needles and display and ordered the GARW unit. I don't know if they were ready to ship or if I'm on a waiting list. Hopefully, I'll see it maybe by the end of the month. I'm looking forward to the updated cockpit.

It looks great to! I finally got around to installing mine over the weekend, had it since Dec. Minus a trip to the autostore for correct gauge quick splicers, the whole job takes less than an hour. I've taken my cluster out a few times so was familiar with removing it so that helped.

binnacle for 8" screen

do we have anybody that is making the larger binnacle that would fit the 8" screen?
