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 FTDI chipset and tested to work with Megajolt, Megasquirt and Emerald ECUs.

Tacho Driver
From
!
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 recent rev counter accepts the 5 volt output of most ECUs then you do not need one of these.
For 4-cylinder, wasted spark installations or two-cylinder independent coils use the 2-input version.
  • For 6-cylinder wasted spark or 3-cylinder triple coil installations use the 3-input version.
  • For 8-cylinder wasted spark or 4 cylinder coil-per cylinder setups use the 4-input version.

Extra-long crank pulley bolt

Extra-long crank pulley bolt with allen-style head suitable for A-series engines. Comes with new thick washer.

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.
