FS: Civinco BC500 EMS
 

For sale is a piggy-back engine management system for cars up to 5-cylinders. This EMS tunes fuel, boost and timing as well as having inputs to control water injection and other PWM add-ons. The main unit is very compact. It includes 2 smart cards for storing 2 separate tunes. When inserted into the main unit, it temporarily overrides the main tune stored in the main unit. This is useful for storing maps for track days, passing emissions testing or winter tunes.

Note that this is a piggy-back or in-series EMS, not a standalone. However it is fully programmable. The website shows the software used for tuning the unit.

I bought it for a 5-cylinder project car but never got to install it as I have decided to go with an off-the-shelf tune.

$450.
