Sneak Peak at injector coding via INPA
After a lot of reading and learning, downloading and experimenting, I finally got INPA to work with my ECU (many thanks go to nivedhm). This is a sneak peak at the injector screen. At this point, I believe I am capable of coding my own injectors.
Few notes: The two 3-digit numbers actually have a decimal point separator. So if your injector has the following stamping on it: 582 227 It actually means 58.2 and 2.27. In this screen you can see how these are entered in the ECU for injector 1: My next step is to verify that my currently installed injectors are actually coded in correctly! After that, I'll be replacing injector 1 in an attempt to rectify the misfiring issues I've been seeing. EDIT: I did some more digging. The second number represents the actual flow rate of the injectors. It measures in milligrams per pulse. So for an example, my number 1 injector will dump 2.44 milligrams of fuel per pulse. It is now clear to me (at least) that in order to do proper tuning of big turbo and upgraded turbo's one would need to know the actual flow rate of the injectors. I think that the flash tuners will have an edge when it comes to big turbo tuning once they figure out how to read the flow rates of the injectors and more importantly, change the frequency of the injector pulses!

I believe that you have to check that you buy the correct cable... do not buy chines ones as they might give some issues...

I will build a complete DIY for you guys. Unfortunately the forum rules do not allow me to post the actual software directly here.
Unfortunately, the weather in Chicago is rather cold. If we get couple of warm days I'll work on the car and replace the injector, but from the looks of it, I might have to wait till spring time to do this. As a side note: I have a brand new injector sitting in my living room, waiting to be installed. It's numbers match EXACTLY my number 6 injector. So it seems that those injectors sometimes will have the same flow specs.

Nice going
Hopefully this will help solve a lot of those annoying misfire problems that are plaguing us. A DIY will save everyone a lot of time and headache! |
