First post here, I'm researching some information about the modifications that need to be done to the wiring in order for a MX5 PNP Speeduino to work with a late 1.6L Euro car.
In my understanding so far, these later models switched to full sequential injection and used a 2-plug harness similar to the '94-'95 1.8L model, with some differences mainly for the fuel pump management and said sequential injection.
The only table I was able to find online is this:
So if I buy a PNP (I'm planning to purchase the CORE4 kit with IAT, TPS and onboard WB, eliminating the stock MAF) I must adapt the wiring from the yellow column (1.6L early 115hp model) to the first column.
In the Speeduino Wiki, there is a paragraph about settings for the 1.8L engine (fuel pump output on pin A9, tacho out on pin 49, demister wire if needed): would it make sense to use those in my configuration, since my car mostly uses the same wiring?
If I set Speeduino to use sequential injection, would the hardware already be configured to use the ECU outputs 2Y and 2Z for injectors 3 and 4?
Thanks for any help/suggestion!
