This is one for the tech guys out there that have some upper level Engine Management, or guys who wish to have a useful Fuel Pressure Gauge. As some of you guys may know, most of these ECUs have strategies compensating for fuel pressure and temperature. There is only one problem... when using a boost referenced regulator, this function is near useless unless your fuel pressure sensor can read the same pressure differential that the injectors see.

Think of it this way: Your fuel pressure is actually the relationship between the manifold and fuel rail pressure. With 45psi to atmosphere, and -15psi vacuum in the manifold, your actual fuel injection pressure is 60psi, which a standard pressure sensor based on atmosphere cannot see. There is no way to properly correct fuel pressure unless the normal pressure has a static number. Well, a boost referenced regulator and a differential pressure sensor used in tandem solve this problem. The regulator and sensor both reference the manifold pressure, and as a result, will always output a static number, regardless of the manifold and fuel pressure compared to atmosphere- unless of course the fuel pressure is actually dropping off in relation to its reference

The problem? There is no regulator in existence that can accept this type of sensor, even with modification, and the sensors do not lend themselves well to retrofitting elsewhere.

Well... we have a solution in the works. It will be a regulator manufactured by one of the most well known and world renown manufacturers, and have built in provisions for this exact sensor type. We will be the only distributor for this product, and will be supplying regulators, sensors, connectors, and terminals as a complete kit. An added bonus? A temperature probe is part of the pressure sensor, and can track fuel temperature for compensation, or even for controlling a small cooler & fan control on the return to the tank for the real hot weather guys.

We know this is not a product for everyone, but this is something we are integrating into our newer builds along with PWM closed loop fuel pump control, so I figured I would offer the components to the extreme tinkerers and tuners out there. This is by no means a Viper specific product.

Pricing is expected to be around $600.00, with Reg, Sensor, Connector and Terminals. These have (2) -10 inlets, (1) -8 Outlet, and a base pressure range of 0-72.5psi, and can handle over 100psi of boost with a large safety margin.

If interested, post up. Looks to be about 7 weeks until availability.
