I'm not sure the "initial basic set-up" accounts for the O2 sensor being cancelled (they seem a bit vague on that point).

Having had a look at the EJK site, and from what I (think I) know, you will most probably need to set the Green/Blue setting to the lowest point; because when you remove the O2 sensor the engine will lean out from idle upwards.
You will then need to add some to the Green setting, to find the best idle... if you're familiar with carburettors, this setting is like tuning your primary or pilot jets.

The Yellow and Red zones are like main jets and an adjustable accelerator pump. These probably wont need much, or any, changing.

Play with the demo at http://electronicjetkit.com/tuning.asp and you should see what I mean by looking at the graph as you make the changes.<!--QuoteEnd--><!--QuoteEEnd-->

Initial report: Installation was not easy at all and it took some time to understand that one harness is good for the 2 injectors. According to the instructions you need to connect their harness to the injector itself - which, of course, is not the case, as you need to connect to the plague that sits on the mutual harness that joins both injectors.
Then we forgot to disconnect the Minus cable of the battery (the unit just did not respond when the power was turned on..). We then attached the ground wire to the metal frame and it started responding but not as expected (LED colours not flashing as expected). We disconnected the O2 sensor by just unplaguing it. Cancelled air box mod.

Went on test-ride - much worse behaviour at low gear low revs low speed! I suspect something is wrong with the installation as the LED are not flashing in the expected order. emailed manufacturer tech support for advice (gave detailed account) and will wait for their reply...
