DUAL COMPUTER:

Computer description..... The computer is made by Real World Solutions adapted for the LS2 V8 and Honda V6 by Vesta Inc. The pickups, and wire harness are integral to the Vesta PSRU. The need arrived for this computer when research using the standard LS1 and Honda V6 computer failed to provide a fully redundant operation. There were also problems with the O2 sensors being coated with 100LL, and difficulty building a reliable dual wire harness for the complex automotive computer. The new computer is very simple (only three sensors MAP, IAT, CKS) and it is fully redundant, with dual circuits, dual sensors, and dual pickups. Because O2 sensors are not used, 100LL is very usable as well as auto gas. In the cockpit there is a Computer A and Computer B switch (like Magnetos switching) which gives the operator instantaneous switching capability (no restart). The fuel and timing curve are adjusted in an open loop configuration and the operator has manual override over the mixture control (using and EGT gauge). The operator also has control of the programming. The operator can create what ever timing or fuel curve they want. An emergency mode can be created that will go to high rich and retard in the event of coolant loss. There are hundreds of these computers flying in aircraft today.
