FM O2 signal modifier
A stock ECU can pull over 30% of its fuel if it thinks the engine is running rich. The actual amount depends on the model of car. This is a problem when you have a boosted car and you`re trying to deliver more fuel. At best, this means poor driveability until the computer goes into open loop mode. At worst, it can have catastrophic and expensive results. The signal modifier prevents the ECU from seeing a rich condition under boost. Simple installation and no effects when the car is not generating boost. Actually, we recently redesigned it for better reliability, easier installation and a smaller footprint!
A popular addition to cars equipped with Powercard fuel management as this solves a characteristic lean mixture at part throttle. Not needed for the Voodoo Box.
Also very useful for Mazdaspeed MX-5 turbo cars with aftermarket intakes. This helps solve a characteristic hesitation problem that appears when the car spools up faster than stock.
Intended for use only with stock ECU. Not required for cars with full replacement ECUs such as our 1990-97 Link or the Hydra Nemesis. If you have a "narrowband" A/F meter that uses the stock O2 sensor, it will read incorrectly when you are in boost - well, more so than usual. Sorry, the little baby Miata is not included.
