FXL22 Off the market 16 November 2005

The reason it was discontinued was that customers would buy the system, then ask for more options and channels than it could provide. Therefore, the decision was made to only sell the FXL35 as it is unlikely that anyone will use all the channels that it has.

A fully optioned FXL22 became more expensive to make and sell than an FXL35. If a customer does not want the thermocouples of the FXL35 system, then the price is reduced accordingly.

The target market for the FXL22 was Group 3 where the customer may only want to record engine and drive shaft rpm to monitor clutch or converter slippage. The FXL22 excels in this market. It has the option of also recording eight exhaust gas temperatures, three pressures and now two oxygen sensor voltages. It idealy suits customers who have a V8 with one or two carbs, manual or auto transmission, MSD ignition and who don't intend to supercharge.

The FXL22 is a 9 to 22 channel data logger designed specifically for Drag Racing. It has one module which can record four rpm's, four switching inputs and battery volts. The other optional module has the thermocouple amplifiers, the three pressure sensors connections and two oxygen sensor inputs.(Oxygen sensors are not supplied) It has a recording time of 18.88 seconds.

It can log:

Four switch positions:

1. Wide Open Throttle - Standard. This triggers the recording.
2. Two Step or Transbrake - Standard. Voltage seeking. This is the normal Record Inhibit line.
3. Two Step - Standard. Earth seeking, like the old Dyna ignitions and new MSD ignitions. This is the secondary Record Inhibit line.
4. Shift Light - Standard, but only for 12 volt bulb shift lights. Records when the shift light is on. Not for LED lights.

Four rpm's:

1. Engine RPM from the tacho terminal of an MSD ignition - Standard.
2. Transmission Input Shaft RPM - Optional for Manual Transmissions.
3. Drive Shaft RPM - Sensor and collar supplied standard.
4. Right Hand Front Wheel Speed in MPH - Sensor and 5 magnets standard.

RPM pickup and untrimmed collar with four magnets

Magneto equipped engines may need the optional crank pickup and magnet kit.

An aluminium collar is supplied for the driveshaft rpm. This collar is only basically turned up and has a hole (approx 25mm) in the center. The customer has to trim and skim the sides of the collar and turn the centre in a lathe and press it to the yoke of the pinion of the diff or the output shaft of the motorcycle transmission. Cars have a four magnet collar, Japanese motorcycle customers get a six magnet collar and Harleys get an eight magnet collar.

Eight Exhaust Gas Temperatures ( $1200 Option )

Eight K type Thermocouples and loom are supplied with the Thermocouple Amplifier Module. The thermocouples are a short probe 110 mm ( approx 4.5 inches ) long. Each thermocouple requires a braided cable. The standard length is 2 meters. Any extra length is charged out at $8.00 per meter.

Battery Volts Monitor: Battery Volts monitoring is standard. It is monitored internally from the supply voltage

Pressures: The latest version of the thermocouple amplifier module now takes only one stainless steel sender (4-20mA) and two VDO oil pressure senders. Choose from the following:

Stainless Steel pressure senders: The pressure ranges and prices for the stainless steel senders are:

• 0 - 200 psi Normally used for fuel injection pressure, $450 each.
• 0 - 100 psi Normally used for boost pressure, $450 each.
• 0 - 50 psi May be used for boost pressure or carby fuel pressure, $450 each.
• 0 - 25 psi Absolute. This pressure sender monitors from total vacuum to 10 psi above atmospheric. It can be used for up to four separate functions, although not at the same time. It can be used to monitor scoop pressure, fuel pressure up to 10 psi, sump vacuum and plenum vacuum. If you run a normally aspirated engine, then this is the one pressure sender you should have, particularly to monitor scoop pressure. If the scoop can make 1 psi of pressure, then you will get 7 percent more power. Pro Stock cars can get this at 170 mph. This is why some cars can overhaul others at the top end. $450 each.

VDO Oil Pressure senders: (Metric rating)

• 0 - 2 Bar (28 psi) Rarely used, not held in stock.
• 0 - 5 Bar (72 psi) Rarely used, not held in stock.
• 0 - 10 Bar (140 psi) Normally engine oil pressure.
• 0 - 25 Bar (360 psi) Normally auto trans oil pressure.

The VDO senders do not read out correctly on the graph. A conversion sheet is supplied so the customer can read off the binary number against actual pressure.

Pressure senders are not covered by any form of warranty.

Cables:The system comes with a wiring harness cut to the customer requirements, 1.5 meter downloading cable to connect the logger to a lap top and DOS based software for downloading the data and viewing the graph. The customer is required to quote the cable lengths from a list. There is an optional 10 meter long Downloading Cable if the customer will be keeping the computer in the trailer rather than having to mount the computer beside the logger for downloading. This cable is $105.00 if purchased separately or an extra $60.00 if selected as an option rather than the 1.5 meter Downloading Cable.

Sample Rate is 100 samples per second for all channels except the exhaust gas temperatures which are sampled 12.5 times per second. Recording time is 18.88 seconds triggered from the Wide Open Throttle switch when the two step or transbrake is released. This lines up the start of the race with the Time Zero on the Graph. There is a small portion of the recording ( 1.6 seconds ) left behind the Time Zero, which means the total recording time is actually 20.48 seconds.

Price starts at $(off market) and this is for a fully working system to suit a race car with an MSD electronic ignition and an auto trans or a motorcycle with a Dyna 4000 ignition.

This includes:

• 1 x FXL22b Data Logger with Serial Number quoted. Serial Number and Customer Number are the same.
• 2 x RPM Pickups. This is for the driveshaft rpm and front right hand wheel speed. These pickups are identical and can be swapped. 5 x 1/4 x 1/4 inch magnets are supplied for the front wheel.
• 1 x aluminium collar with 4, 6 or 8 magnets pressed into the outer rim.
• Locking on-off switch. This is the power switch and connects the battery to the logger.
• Wide Open Throttle switch. This is a simple micro switch that the customer fits under the accelerator pedal of the car or the twist grip on a bike or somewhere.
• Loom cut to the customers requirements. The cable requirements are listed in the features section.
• 1.5 meter downloading cable. This suits laptop computers. If you want to use a desktop computer in the trailer, it is highly recommended that you purchase the optional 10 meter cable for an extra $60. The customer must ensure that their computer has a 9 pin serial port (RS232C). The downloading cables are known as Null Modem cables.
• DOS based software is standard.( Windows software is now available)
• Tax Invoice with price paid and amount of GST included in the price.

Customers should seriously consider buying the FXL35 if they want to monitor exhaust gas temperatures or pressures. The FXL22 is sold as a split system, which means that it records the 4 switches and 4 rpms and battery volts in one module, and needs the optional $1200 Thermocouple Amplifier Module if they want to monitor EGTs, pressures or oxygen sensors. The latest thermocouple amplifier module does not support the G Meter.

• Optional 8 x Exhaust Gas Temperature probes ( EGT ) and amplifier module. Customer to quote what fittings to use, either 1/4 BSP 18 tpi recommended or 1/8 BSP 28 tpi. $1200.00
• Optional RPM Pickups and magnets to suit transmission input shafts are custom made and cost $125.00 each.
• Optional Stainless Steel Pressure Transducer is $450.
• Optional VDO Engine Oil Pressure sender is $115.
• Optional VDO Transmission Oil Pressure sender is $125.
• Freight is extra.
