Injector Question
 
02 Miata MS3Pro PNP
I just installed the ID 1300x2 model. In tuner studio what value do I use for these? I ask because there's logical choices according to the chart below. This is from the slope & offset vs pressure. Do I use the 14v value since the car runs at 14v, the 12v value since it is a 12v system or the slope value? I am probably overthinking this but want to be sure.

You input all the voltage values into the table that accepts them at the pressure you are running. I have data from 10V to 15V for my injectors, so my table reflects the data points and interpolates the rest.

go here
Megasquirt : Injector Dynamics Support

input the pressure you're at and it gives you all the data you need. or email them and they'll give you what you need

Ok thanks guys, I changed this in req_fuel but I don’t see a table to input the values to. Searching now for the table

I think I found it:

Fuel Settings --> Injector Dead-Time/PWM
Fuel Settings --> Injector Small Pulsewidths

Then input the data from the spreadsheet?

This creates Dead time voltage % curve 1
then tell it to use curve 1 for all injectors, if this is the case the default curve sucks hard core, its at 100% across all voltage ranges. AM I understanding this correctly?

yes.

Rasta420 03-19-2018 06:35 PM

thanks dude!

I am also setting small pulsewidths curve
