Code Scan / Reset Tools

Peake Research Code Scan / Reset Tools
What is the Check Engine light trying to tell me? The BMW Check-Engine light can mean any number of things.
Sometimes it's alerting you to the real need for a repair, but most often it is merely indicating one of the many, simple (top off your coolant, loose gas cap or oil cap) type problems. Imagine paying a hundred dollars to a repair shop to tighten your radiator cap and reset the Check Engine light. Without the R5/FCX, you're stuck staring at your Check Engine light until you see the mechanic who can reset it. Routine Maintenance Lights - As an added benefit, the R5/FCX includes the ability to reset the oil service and inspection, routine maintenance lights. Considering that an oil service for a BMW can sometimes equal the price of the R5/FCX, this feature alone is worth the price of the R5/FCX. Manual and Code book included.
No more driving around with those lights on! Do you change your own oil or go to a fast lube? If you do, then the R5 reset tool is made just for you. The R5 gives you the freedom to reset your own Oil service/Inspection lights, allowing you more choices in service. Super easy to use, takes 15 to 20 seconds, and you don't even have to get your hands dirty! Includes Instructions.

To select the right tool, please be sure to view the Peake Research Application Guide.

It's also highly recommended that you check out our Pelican Technical Article on Reading BMW Fuel Injection Fault Codes.

Known Incompatibilities for the R5-FCX-3 Code Scan and Reset Tool:
  • 325/e/es (1987), M3 (1988-91)
  • 528 Euro-spec (1988) (528e is compatible), 535i/is (1987-88), M5 (1988)
  • 635/M6 all (1987)
  • 735 all (1987)
Model year 2000 ONLY: There was a change made in diagnostic systems for most BMW models in 2000 and one must verify if vehicle is equipped with the 20-pin diagnostics plug in the engine bay for these cars. This information CANNOT be deciphered by VIN. The exception is:

X5 models 2000-2001 = need to verify if vehicle is equipped with the 20-pin diagnostics plug in the engine bay.

All models - if equipped with plug in the engine bay use FCX-3 or R5B. If not equipped, use FCX-3-16.

NOTE: For Vehicles equipped with BMW iDrive Systems this tool scans and resets Engine Management Codes ONLY - Will NOT reset the Service Indicator or Oil Change Lights (these are reset manually).

NOTE: Peake Research scan tools are incapable of reading ABS/DSC module codes.

Diagnostic Scanners

Air/Fuel Ratio Meters

The LM-2 combines an air/fuel ratio meter, a full-function 32-channel datalogger, and powerful software to deliver a complete tuning workshop for less than the cost of one dyno day. Whether you have a piggy-back fuel controller, race carb, aftermarket ECU, ODB-II tuning software, or a flash/chip programmer, an LM-2 is the tool you need to dial in maximum HP. The meter's digital signal processing technology provides data on exactly how rich or lean an engine is running at any load. The LM-2's self-calibrating circuitry also compensates for changes in temperature, altitude, and sensor condition.
  • Patented Direct Digital Wideband Technology
  • Wideband O2 Compatible with ALL fuel types
  • Single or Dual Channel Version Available
  • OBD-II Scan tool- read/clear DTCs and log up to 16 channels of CAN OBD-II Data
  • Log directly to SD card (included)
  • Playback log data on screen and/or with powerful LogWorks software (included)
  • Large high-contrast graphics LCD
  • Built-in RPM converter (direct frequency or with optional inductive clamp)
  • 4 fully-differential analog inputs
  • 2 configurable linear analog outputs
  • Positive lock connectors for all connections
  • Innovate MTS serial IN and OUT
  • USB connection to your PC
The LM-2 also features two fully programmable linear analog outputs to connect to analog gauges, dyno computers, ECUs, piggyback controllers, and other devices with analog inputs. Analog output 1 comes setup from the factory ready for narrowband simulation; analog output 2 is configured as 0 volt = 7.35 AFR and 5 volts = 22.39 AFR. With the provided LM Programmer software these analog outputs may also be configured by the user.

The LM-2 Kit (Single Wideband O2) includes the LM-2 meter, Bosch wide-band oxygen sensor, 10 ft sensor cable, cigarette-lighter power adapter, analog in/out cable, ODB-II/CAN interface cable, SD memory card, USB cable for PC connection, weld-in bung and plug, LogWorks software CD, and quick-start guide. Carrying Case also included!

WEGO IV Wide-Band Air/Fuel Ratio Tuning Aid
The WEGO IV is a highly accurate and complete air/fuel ratio metering system with built-in data logging. The unit displays air/fuel ratio (AFR) and continuously logs over 2 hours of data, including AFR, engine RPM, and a spare 0-5V analog input for sensors such as throttle position or manifold pressure.
  • Includes Bosch LSU 4.2 oxygen sensor, 96" sensor extension cable, 18 x 1.5 mm weld nut for exhaust pipe, USB cable, and software for downloading and charting
  • Data is easily exported to a spreadsheet
  • Attractive black anodized aluminum housing with convenient front panel mini USB port, compact size: 3.3"L x 2.1"W x 0.9"H
  • RPM input signal connects directly to Porsche tachometer - no adapter required
  • Easy free-air calibration for sensor aging effects
  • Ultra-bright daylight readable blue LED display and automatic dimming under low light conditions
  • 0-5V analog AFR output for interface to dyno instrumentation
  • Industrial grade clamping terminal block on rear panel allows easy hookup
Available in either single or dual channel. Dual channel unit displays and logs two channels of AFR data. The 12 foot extension cable is sold separately and is necessary for installation in a rear engine car (two are required for the dual-channel unit).

K&N Air/Fuel Monitor
The K&N Air/Fuel Monitor is designed to help the performance enthusiast calibrate and fine tune the air/fuel mixture ratio. It is an invaluable diagnostic tool that has a place in everyone's tool box, or you can install it in your car to give you real-time readings. This kit continually monitors an engine's air/fuel ratio while the engine is running. It is extremely sensitive to air/fuel ratio changes and will show them instantly and accurately, within the range of the oxygen sensor.

The instrument works whether the engine is carbureted or fuel injected, normally aspirated, turbocharged, or supercharged, and at any load condition. This precision instrument also works with nitrous oxide, but will not work with diesel or nitromethane fuels. This kit comes complete with an oxygen sensor that must be installed into the exhaust system by welding. If your car is already equipped with an oxygen sensor an air/fuel monitor may be purchased separately and wired into the existing electrical system. An oxygen sensor is also available separately.

Vehicles with dual exhaust systems can utilize an oxygen sensor in each headpipe or collector that is controlled by a switch that will allow each sensor or bank of cylinders to be read independently. This can show if there is a fuel distribution problem within the intake system, or help to pinpoint a potential problem in advance.

Valve Spring Compressors

Valve Spring Compressor Protective Cover - Cylinder Head Saver  
[ More Info ]

Note: Black Delrin protective cover that clips onto valve spring compressor tools. Provides protection against contact with cylinder head and sharp edges of the spring compressor. Fits most spring compressor types.

Brand Rating

With this latest evolution to our Universal Valve Spring Tool we have added the ability to actuate the compression tube even in tight confined locations like under the cowl where the lever cannot be moved or may not even fit. By adding the ability to separate the lever from the compression tube anywhere along the bar you can compress the springs that are confined by brake boosters, AC housings or other factors by locating the lever along the bar where there is open space.

  • Access to valves in areas that are not in open areas with engine in vehicle
  • Valve springs can be depressed "remotely", depressor bar and compression tube are separate
  • Complete universal kit with multi adjustable points
  • No need to remove engine due to confined areas saving time
  • No other valve spring compressor is as universal and adjustable
  • Depressor tube slides easily to each valve location without changing settings
  • All components store neatly in a blow molded box
