I want to order pretty soon now but I still have questions about what I have to order.

This should be able to run ignition and injection without problems.

Q: Do you plan to build your own harness or re-use the stock harness with it's limitations? There are things you should order to make it easier to build your own harness, like the injector connectors.

  • I deff would like to built my own harness so I need the connectors. Any other items?

Q: What kind of cable will you use for serial communication with the Genboard? A preferred method is to use the "serial jack kit" from the webshop, which is basically a 6.3 mm stereo jack female+male. Mount that in your dash somewhere and wire it to the serial pins on the EC18 connector. This involved building a custom serial cable to connect your computer with a male 6.3 mm plug in one end and DSUB9 female in the other end.

  • I guess I will use your method and use a USB port.

A keyboard and LCD can be used to adjust anything (including maps). However you really do want a notebook and MegaTune to tune the ignition map.

EDIS (wasted spark) coils for ignition should work. (I assume you have the connector for the EDIS coil)

Assembled v3.3 controller 451.10EUR

Other items:

Total: 587.62 EUR

I guess I can replace the last two sensors with Bosch 0 281 002 177.

Do think of how/where to mount it.

  • I want to mount this on the inletmanifolt but as close to the throtlebody as possible.
