Yes, it'll be a single 48mm body with one injector per cylinder. I'm not sure of the output from the distributor Hall sensor but it is the same sensor as fitted to 1980's VW Golfs, Vauxhall Astras etc. The sensor is described as an 'Intermotor 14006 ignition pulse sensor' on some websites. The distributor has both mechanical and vacuum advance but both will be locked down.
My main objective for this year's project is to get the ignition under control as the advance curve of the distributor is way off, it's one from a low compression Bedford CF van with a 42 deg mechanical advance at about 3200 rpm plus 6 deg vacuum. At the minute I need to run with virtually no static advance to get decent mid range and top end power.
As I say, get the ignition under control this year while fabricating the injection bits to fit next year......or the year after..... It took me 35 years to build the car
Can I run sequential injection with only 2 injection channels on the NO2C? I'm not sure if batch injection of will work efficiently enough as I will be mounting the injectors quite far from the valves.
My MAP sensor will be the standard MGF 4 wire sensor which I believe gives out a 5V signal but I'm not sure. It's the one in the picture below.
Firstly we will need to establish the trigger signal from the distributor.
I feel it will likely be "basic distributor" which is a pulse for every ignition event.
See here: https://speeduino.com/wiki/index.php/Basic_Distributor
You would not be able to run sequential injection with this type of signal due to the signal not providing any reference of what degrees the engine is currently at.
A way around this that some people on here have done is to get a custom distributor wheel made up that will give a signal that can support this whilst looking stock.
Take a look here.
That aside for now, if you lock off your distributor and keep the rotor arm in there you should be able to get speeduino running the ignition side if things without too much hassle.
I had a look at that MAP, there should be no issue using that at all.
On a side note.
I'd advise starting a thread in user projects: viewforum.php?f=19
Posting the steps you would like to progress this in.
There might be someone in there who would have a better strategy than just me here in my thread.
Then once we have gotten down what you need to get you running can sort out an order.
