M.A.F. controller the MAF Demon for Land Rover TD5 engine tuning

The M.A.F. Demon was developed to allow the user to make adjustments to your Land Rover TD5’s response & acceleration tolerances programmed with 9 settings PLUS a diagnostics mode & fail safe, also use to eliminate the misfire when boost pressure is increased on some Defender models caused when the M.A.F. sensor does not send a full scale air flow reading to the ECU.

After a few thousand miles on the road no two engines run exactly the same, the condition of their parts & sensors will vary making the M.A.F. Demon an affordable upgrade and the simplest way to make adjustments to get the best performance from your engine.

Use setting 0 for diagnostics mode, 1 or 2 for towing where a higher torque is needed at lower speeds, 3 to 9 to adjust response & acceleration tolerances to match your set-up and the condition of your parts & sensors.

Comes with simple to follow instructions, fixing pads, de-greasing wipe & settings tool, can be mounted on your M.A.F. sensor in just 5 minutes or less by any competent D.I.Y. enthusiast or one of our supplier / installers.

NO need to remove, cut or joint any of your ECU / ECM wires !!

The M.A.F. Demon has been developed in the UK with over 30 years experience in the Computer, Automotive & Electronic Industries. The entire Demon range of products are manufactured using the latest high speed parallel tasking micro controllers, using quality OEM grade cables, parts & connectors, making installation simple, fast, reliable, robust & affordable .. just Plug-in & Go for high performance tuning made easy ..

Please Note:

If you are increasing your performance disable your EGR valve by removing & blanking the vacuum pipe, for best performance use an EGR bypass kit

In good condition your engines performance can be increased to 200 + hp depending on the performance parts fitted, in the interest of safety make sure your brakes, steering and suspension parts etc. are in good working order (if in doubt go to your nearest Land Rover specialist and have them run a diagnostics health check first)
