USB-serial adaptors

USB-serial adaptor for computers lacking a serial port.

Many new laptops and PCs do not come with a serial port.  These adaptors plug into a USB socket and allow you to connect up to your ECU. 

Many cheaper adaptors give problems, these adaptors use a premium chipset and tested to work with Megajolt, Megasquirt and Emerald ECUs.

Hard cut rev limiter

Hard cut rev limiter board for Megajolt systems
The Megajolt ECU includes an ignition retard rev limiter as standard.  The hard cut module works with the existing soft rev-limit and fits inside the ECU case.  When installed the soft-limit of the ECU automatically retards ignition timing to zero degrees 100 RPM before the hard limit activation point. This makes for a progressive application as you reach the rev limit.

Tacho Driver

Tacho
tachodriver130
Tacho driver module for coil-driven rev counters
Suitable for Megasquirt, Megajolt and many other ECUs the tacho driver allows you to retain your existing coil driven rev counter.  If you have a more modern rev counter accepts the 5 volt output of most ECUs then you do not need one of these.
