Enricher
Universal Fuel Enrichment Module

The Enricher is a miniature electronic module that can be used to achieve fuel enrichment in both turbocharged and supercharged applications. It is compatible with virtually all late-model engine management systems. The Enricher addresses the specific requirement of adding fuel when an engine is in boost and the ECU is in closed-loop.

Modern ECUs operate in closed-loop mode over most of the load and RPM range. While in closed-loop, the ECU is very efficient at maintaining an air/fuel ratio of 14.7:1. When an aftermarket turbo or supercharger is fitted to an engine, it is desirable to run at a much richer fuel mixture when the engine is in boost. Efforts to add fuel in boost are quickly overridden by the fuel trim that occurs in closed-loop. The Enricher alters the target fuel mixture in boost so that the stock ECU targets a user-adjustable richer mixture.

Modifier
Dual Channel Universal Signal Modifier

The Modifier is a miniature electronic module that can be used to adjust a variety of signals on modified engines. It controls the gain and response time for two independent signals. It is particularly effective at maintaining signals within their normal operating range on modified naturally aspirated and forced induction engines.

When an aftermarket turbo or supercharger is fitted to an engine, the load sensors read much higher than normal. In many cases, this elevated reading leads to faults that result in fuel cut or a check engine light. The Modifier provides a simple way to compress the sensor reading so that it stays within the normal operating range. The Modifier is a nice companion product for ECU reprogramming tools. In many cases these tools can be used to re-map the fuel curve, but cannot address faults caused by the sensor over-range problem.

ESC1
Narrowband O2 Sensor
Signal Conditioner

The ESC1 alters the signal from narrowband oxygen sensors under boost conditions. It may be used in either single or dual EGO sensor applications. Under vacuum conditions it outputs a signal which is identical to the EGO signals that appear at the input. Under boost, it outputs an internally generated dither signal (cycling pattern) to defeat adaptation by the Electronic Control Unit (ECU).
