    7. click on FILE/SAVE
  4. Your laptop is now ready for downloads.
  5. If you want to copy your your old runs from old to new laptop follow these steps (this takes some computer expertise - if you don't already know how to copy and paste files get help - don't call me when you are halfway tru and don't know what you did - just do it all from the start or get someone to help you that knows computers):
    1. Get a USB thumb or flash drive from an office supply store. Put it into the old laptop and windows will pop up a discovery message - click on open folder to view files and then minimize that window.

How to connect a MSD Power Grid

1. Use a V-net T cable with the straight end into the Grid harness and the T end anywhere in your V-net network.

2. If you have a Sportsman, you must be on Datalink 4.8.8 or higher and your firmware must be Product Version 5 or above. To check Datalink version, load Datalink, go to Help and click on about. To check your Firmware/Product Version click here Firmware . Each Grid channel uses one Sportsman channel so usually you only enable timing.

3. If you have a IQ3 drag dash keep in mind that each Grid channel uses one channel so usually you only enable timing.

4. You must ENABLE whatever channels you want in the Grid software (Some early Grid 7730's have all channels enabled so you have to DISABLE all but the ones you want)

How to Diagnose no DS RPM

1. I do not know of any ohm test to verify the sensor.

2. Check the gap from collar/magnet to sensor - it should be .050-.080'.

3. Inspect the sensor for damage. It's easy to over tighten the two nuts and crack the sensor body.

4. Check power & Ground to the sensor:
Unplug sensor from the cable. The terminal at the top of the diagram to the right should have full battery voltage, the bottom terminal should be a good ground.

5. Confirm the magnets have the south side pointed towards the sensor. Collars that did not come from a Racepak dealer may not be oriented correctly. Magnets can also go bad particularly from heat. Your Racepak sensor came with a yellow checking magnet and the checking procedure.

6. Test the harness/system by starting a telemetry session and with a small screw driver momentarily jump from ground to signal with quick momentary motion. The DS RPM should show low numbers (12 - 50 - 6 for example). If you get DS RPM in this test then the sensor or magnets/collar is bad.

How to Download/replace a Configuration file sent to you (GMAIL)

This procedure assumes your Email is on the laptop you run Datalink from.

This will open Datalink with your changes.

Go to File, Save As and you should get the following screen. It MUST say Sportsman in the save In box. You may have to navigate with the drop down arrow shown below so the result is C:RacePakDataSportsman

Click on Save

exit Datalink

Go back into Datalink and make sure your new channels are there.

Machining a collar to a new size

  1. Use .040 spacers between halves (without the spacers the collars are not round. They measure true across the parting line)
  2. keep heat down as 200*F will hurt magnets
  3. if you remove magnets make sure you get south side facing out

How to E-mail a Configuration File

  1. Go into your E-mail system.
  2. Start a new e-mail to your intended recipient
  3. click on Attach or possibly Insert (frequently has a paperclip icon)
  4. If a choice comes up, select file/attachment NOT pictures.
  5. Use the Browse function to navigate to Computer
    1. then C: (sometimes OS C:)
    2. then to the RacePakData folder
    3. then
      1. if you have a Sportsman recorder go to Sportsman folder, and select Sportsman_Config.RCG
      2. if you have a IQ3 Drag then IQ3 folder and select IQ3drag.
      3. If a V300SD go to V300SD_NNN (your serial number) folder and select V300SD_NNNN.RCG
  6. add any message you want to include then click Send

If your laptop can not access the internet you can copy the selected file to a USB memory stick or flash drive then go to another computer and e-mail the fire from the USB drive.

How to measure for the DS collar

Factory yokes usually do not have a concentric spot. They need to be machined or replaced with an aftermarket yoke.

With how far automotive technology has come in recent years, there is no reason why older platforms with outdated electronics can’t be brought into the 21st century. Here we will be installing a Racepak IQ3 Digital Dash and Data Logger into a '93 Honda Civic Si. While it is not needed for the install, if you have a Hondata S300 V3 in the car, you will be able to see and log all information that streams through the ECU through a single wire.

Know the IQ3

The Racepak IQ3 is available in two different versions: Display Dash or Logger Dash. For a road race car, you know we had to go with the best. The Logger Dash is able to display information from the ECU/external sensors, log data such as lap times, and it includes an external memory card slot.

The dash has up to four screens that you can configure however you’d like. There are also progressive shift lights and four warning lights that you can set up to any of the readings coming through the dash. An external button will allow you to toggle through each screen. This is perfect to eliminate the need for multiple gauges on the dash.

Get Connected

Racepak's proprietary V-net connectors allow you to connect all sensors to each other, with only one plug going to the dash, making the installation of sensors a simple, clean process. If you are using Racepak sensors with the V-net module, the IQ3 Dash will automatically recognize what type of sensor you have once connected. It's so easy!

Mount Up

We recommend starting the installation with where you are going to mount to dash. Keep in mind you will need to access the rear of the dash later on for configuring the screens.

We choose a column mount to bring the dash closer to the driver and allow for easy access to both the rear of the dash and memory card slot on the front. Once mounted, the dash only needs a 12V power and ground. All engine information will be read through the V-net harness connected to the ECU.



Once the dash is mounted, we can begin routing the wires. Since the dash is being directly connected to the Hondata S300 ECU, we were able to remove the tach signal and external warning light from the main power harness.

The Honda ECU does not read oil pressure, oil temperature or transmission temperature, so we are using three external sensors to monitor these readings. Once installed on the engine, the wires are routed through the firewall and plugged in to the V-net cable running from the back of the dash.


From there we move to the ECU.

Racepak Drivers

Once the ECU cover is removed, you will see a few small pins that the Hondata provides connectors for with the S300.

Simply connect the Racepak harness to the Hondata harness and connect the V-net plug into the others. Use the Hondata SManager software to let the S300 know you are outputting readings to the IQ3 dash.

Racepak Driver Update


Fuel level readings are always the trickiest part of installing a digital dash; this is largely due to every car having their own way of reading it. To get the most accurate readings, we installed the Racepak Universal Sensor Module (USM), which allows us to convert the ohm reading the car provides to a 0-5 volt reading that the IQ3 needs.

To install, you simply attach the signal and ground wires from the fuel sending unit to the USM. When configuring the dash, the fastest and most accurate way we recommend is to remove the fuel sending unit from the gas tank. You then read the output signal at empty and full and the Racepak software will fill in everything in between. The fuel levels will be displayed as a scale of 0-100 on the dash. It is also recommended to set a warning light on the dash to lets you know when you are getting low.

Your Car, Your Screens

In an effort to not have to toggle through screens anymore that needed, we went with a simple three-screen setup. The main screen shows only the crucial information, while page two shows all temperatures, and page three shows fuel level and the rest of the readings available through the ECU.
