fully closed then the problem does not lay with the FP50 Fuel Processor or the CV30/CE30
stepper valve. If the rotational barrel is fully open (and you were able to adjust the mixture lean by
screwing in the CV30/CE30 power valve by no more than two turns), replace the CV30/CE30.
Start the engine and hold the engine at 1500rpm. If the rotational barrel remains fully open replace
the FP50 (the original CV30/CE30 stepper valve may well be fully operational).
Warranty - First 3 Years (36 months)
Gastec is proud of the high quality components used to manufacture the FP50. This processor is
therefore sold with a three year warranty that is transferable between owners, provided it has not
been abused in any way [ie it must not be melted from excessive heat, must not have been
damaged by fluids such as water, must not be burnt out due to electrical overload (always install
the 10 amp fuse) and it must not be crushed etc]. Within this warranty period the FP50 should be
returned to your local Gastec distributor for repair and/or replacement at no cost to the owner.
Each FP50 is date coded so no invoice is required by the factory.
Warranty - Years 4 to Year 10
The processor should be returned directly to the factory (or to the importer in your country of
purchase) with a payment of US$40 (AUD$40) to cover its direct return. Each FP50 is date coded
so no invoice is required by the factory. The same warranty conditions apply as listed for the first
36 months.
NOTE – Fuel Economy & Air Fuel Ratios
LPG contains only 26 Megajoules per litre compared with 32 Megajoules for Unleaded Petrol (ie
19% less energy). To ensure maximum power while accelerating the FP50 will allow the engine to
run richer on LPG/CNG. This is governed by the TPS sensor.
The FP50 operates around two factory set air/fuel ratios. The rich and lean lights indicate when
the engine is running richer or leaner than the air/fuel ratio chosen by the FP50 at that time. To
determine exactly which air/fuel ratio is currently chosen, you must measure the output of the O2
sensor itself. The standard FP50 programming forces a richer air/fuel ration when the TPS voltage
rises above 3.5 volts. For the standard programming, light load conditions operate around an O2
voltage of 0.37 volts. This increases the vehicle’s economy significantly during light load highway
running. For the standard programming, heavy load conditions operate around an O2 voltage of
0.51 volts. This gives a significant increase is power under heavy load conditions which is ideal for
highway overtaking and when pulling caravans etc.
The FP50 programming was updated in December 2009. It will only further open the CV30/CE30
stepper valve for one acceleration in every 2 seconds. Emissions testing has shown that this
provides the most accurate (richer) air/fuel ratios. The CV30 stepper valve steps at 7.5 degrees,
the CE30 stepper valve steps at 3.6 degrees.
Gastec certify that the FP50 is
CE Compliant
. Installers should contact their closest distributor for
wiring and placement instructions for specific vehicles to comply with local standards and
emission regulations. Updated instructions and information on the FP50 and other Gastec
products may be found at www.gastec.ws
