i have a 2vzfe that im gonna use this on that has a 123456 firing order, i was wondering how i would set up the injectors, i know they need to be seq because the speediunos limited outputs but i don't know how

[jonbill]

They need to be paired not seq with a standard 4 channel speeduino.
The wiki is the place to start, specifically:

+1, @jonbill's reference states

The injectors paired together must have their Top Dead Centres (TDC) 360 crank degrees apart.

The injector pairs (or wasted-spark) is based on pairing cylinders that TDC simultaneously, but fire 360° apart. This is found by separating the firing order of the first crank revolution (0-360°) to the second (360-720°) in the 4-stroke 720° cycle, to find those "sister" or complimentary cylinders.

In your case 1-2-3-4-5-6 would simply pair-up 1-4 | 2-5 | 3-6, as cylinders that TDC together and would be paired for either fuel or ignition.

I run speeduino on my 3vzfe.

One of the official speeduino stores has a adapter board and plug that will allow you to connect you factory loom to speeduino (if using a V0.4 board) best thing I did for my engine conversion
