Spitronics Mercury 3, now with Bootloader, no programmer needed! Upgrades to firmware from 3.6 to 3.7 with new software features to follow shortly, as well as updates to this site regarding the product.

Trigger or Crank Position Sensor
Complex triggers like 36-1 or 24+TDC or any combination of crank and cam triggers can be used
with this class. It has 2 inputs on the ECU and can distinguish signals with a TDC reference like a
missing tooth or cam home pulse. It also works with engines with distributors with complex
patterns like the Nissan optic encoders. Firmware are written for each specific pattern and number
of cylinders. See the ECU selection chart if firmware exists and what the number is.

Coils
This class can do multi-coil type Ignitions. Timing is done Full Sequential spark up to 8 Cylinders
or in a Wasted spark format. This means that the coil has to be charged only once per revolution or 2
revolutions, which means spark performance is at a maximum. For Full Sequential, each coil is
connected to its own driver, and for wasted spark, 2 coils will be paired according to the firing
order. Here they are fired at the same time, even if COP coils are used. Both methods are
recommended for high-revving performance engines. Full sequential is preferred for NOS
applications and long-duration overlap cams. It can do the distributor type one coil systems as
well. See the drawings in the manual for more information.

Injectors
This class can do Full Sequential injection up to 8 Cylinders or Split Sequential injection with 2
Injectors per driver. It will alternate driver pulses in sequence so that each cylinder receives its fuel
on the same stroke. This will make for a more constant condition on each cylinder, resulting in
better performance and economy. For Full Sequential, there is one injector per driver, and for Split
Sequential Injectors will be paired according to the firing order. See the drawings in the manual for
more information.

Features
All the features are allowed with this class. Such as Accurate fuel and spark timing, Idle Control,
Lambda Control, Launch Control, Fuel Pressure Control, Anti-Lag Control, Cam Control, Flat-shift,
Dual Injectors, Rapid fire, Full Sequential Spark, Injector Trimming, Launch Recover Delay,
Retarded timing after TDC, etc.
It can also work with the Advanced, Intermediate, and Standard firmware.

GP Outputs
Up to 10 General outputs can be used for fan control, V-Tech Cam, Shift light, etc.
