Customizing Nexus, how to program your autometer nexus gauges!

Recently I added the TVS supercharger to the car and in doing so I needed a good set of gauges to monitor what was going on in the motor.   I chose the Autometer Nexus gauges for their warning indications and playback abilities.  I have known for a while that is is possible to program the opening and closing ceremonies of these gauges, but it was very difficult to find out how.

I spoke with Autometer who could not help me, I searched high and low on the Internet, and I finally found the answer on a NASIOC forum, which I will be reposting here for anyone else searching for this information.

First, you can use this information to customize the opening, closing, and demo ceremonies.   You will need notepad (not word, word pad, lotus notes, or open office - NOTEPAD), a 2GB or smaller SD card, and some free time.

First, customizing the ceremonies

File Usage
If there is more than one file of the same valid file extension on the SD Card,
the most recent created date and time will loaded into internal memory.

Filenames may be of any length, but will be truncated within the C4 remote
to 8 characters.  Filenames with the same first 6 characters will be
truncated to the 6 characters and a tilde (~) followed by an index number.

File Type Extensions
Opening Ceremony File:  .ocf
Closing Ceremony File:  .ccf
Demo Mode File:       .dmf

FILE COMMAND TYPE ID

TD                      UBYTE         1            0 - 255                     Time delay.  In 10th of second                0×06
LP                       NONE          0           NONE                        Loop command to loop Demo Mode.       0×07
CM                      NONE         0           NONE                        Color Morph turns on in ceremony.          0×08

UBYTE   Unsigned 8-bit value
UWORD Unsigned 16-bit value

You can download the stock ceremonies from the Autometer website, below is a new shutdown file from NASIOC user WR^2X that is more of an “instant off”.

ps 36
dc 0, 0, 0
pp 0
td 6

A quick translation of the closing sequence above would be Pointer Speed set to MAX (PS 36), Dial set to full black (DC 0,0,0),  Pointer Position zero (PP 0) and Time Delay 6.

To load the ceremonies to your gauges you insert your SD card, hold down the demo button on the Nexus remote, and turn the key on.    You should see a short green light and the gauges should boot up right away - that is it!

Hopefully this helps some of you nexus owners out there, it took me forever to find!

Project Lets Go Racing: NRP 3″ Offroad X Pipe and 3″ Magnaflow Catback

Last week I dropped off the project car at Nevarez Racing Products, so that they could develop a new exhaust system for me.   The new system would consist of 3″ pipe, mandrel bent, from the collectors to the exhaust tips and utalize magnaflow mufflers.  Read more

Lets Go Racing, 2010 Gameplan

The goal of this project is to build a 6 Speed, IRS, 8″ Street Tire, Single Power Adder, 10 second car; as if those aren’t enough challenges to overcome.

So I am breaking this down into two steps.   #1 Make the power and #2 Put the power to the ground, this entry will outline Step #1.

Class rules prohibit a big motor, sick heads, and a huge blower/turbo/or shot of nitrous, so this is about as un-radical as it can get.   

• Forged LS2 Engine (364ci) built by Nevarez Racing Products (www.nevarezracing.com)
• Vortech S Trim Supercharger (www.vortechsuperchargers.com)
• T56 Transmission built by Tick Performance (www.tickshift.com)
• Level 5 clutch from Monster Clutches (www.monsterclutches.com)
• Upgraded Differential from Difftechnics (www.difftechnics.com.au)
• Upgraded IRS & Drive train from Gforce1320 (www.gforce1320.com)

That is the plan in a nutshell, of course there is alot more that goes into it than that but this covers the important parts.    This project will be underway shortly with updates to follow.

Prepping the car for 2010 PSCA Street Challenge

My OCD has kicked in again, and I’ve gotten a deal on a TVS supercharger that I just can NOT pass up so it’s time to start breaking more stuff.   I’ve decided to use the car to compete in the 2010 PSCA Street Challenge Class.

Street Challenge is a unique class in that you are not allowed to use a wide nor a sticky tire.   Amazing concept eh?   I imagine it will be similar to drag racing on ice.

In order to do this I will need to change a few things on the car in order to get more power, and to get that power to the ground.

More details on that to come, later…
