Hello.
I have the Speeduino 0.4.3c board and i'm experiencing a little confusion which would look like a rookie question.
I have a Delco ITMS-6F ECU and i'm trying to tap speeduino injector output into the stock harness and i have a question as unfortunately i can only get ahold of generic wiring documentation for Speeduino and not v0.4 board specific.
So the question is:
I have 8 pins on the Speeduino harness i've made:
Injector 1,2,3,4 and all are 1/2 and 2/2 of each output.
I plan to use paired high Z injectors, Inj 1 with 4 and 2 with 3 for a 4 cylinder setup.
A) What is the polarity of the pins 1/2 and 2/2 of Speeduino 0.4v board?
Since i see Speeduino injectors normally wired one side permanently to fused +12v as per the manual, should i assume one of the 1/2 or 2/2 output +12v within the board? Or are just extra outputs of the same channel?
B) For a 4 Injector setup with 2 pairs, what is the wiring on 0.4.3c?
Do i use it as:
-Inj1 1/2 -----> Injector 1&4 pin 1
-Inj1 2/2------> Paralleled with Inj2 2/2 and to Injector 1&4 + 2&3 pin 2
-Inj2 1/2------> Injector 2&3 pin 1
-Inj2 2/2------> Paralleled with Inj1 2/2 and Injector 2&3 + 1&4 pin 2
The above with whatever polarity is correct as i have absolutely no idea.
Or do i use it as:
Taking Inj1 1/2 and Inj2 1/2 and using them for each injector pair's pin 1 and wire pin 2 to fused +12v?
One of the above combinations is wrong and obviously releases blue smoke so i need to figure out what's going on.
Thanks in advance.
