MPGuino release one workspace

Just to be clear, you have to unplug the connector from the injector, otherwise you will see 12 volts on both leads.

Also we are talking about two wires going to the same injector that you are measuring, right?

Thank you for the speedy response..

Yes, I am taking the plug out of the injector(s) (I tried each one just to be sure), alligatoring the negative tester probe to the car body... just ground somewhere...and I'm sticking the positive probe into each of the two injector plug leads. Using DC on the multimeter of course. Both wires going into the plug look the same too :-/

Do you think you could post a picture of the injector? And maybe a link to the cars schematic? You are sure you are looking at an injector? I have no clue about these model specific things so I have to ask a lot of stupid questions.

You mean delete everything from the window I pasted the mpguino code into? Fairly sure...I'll play with it more in a few hours and let you know.

And here's my VSS tap just for good mesaure..


I should probably just post a bunch of pictures now that I have my dash torn apart.

Edit:
Here is an illustration of exactly what is happening

Ok, well there are only two wires to choose from on any particular injector, so I would say try one, if you don't get a signal on the uS field on the instant raw data screen then try the other one.

re vss, I think you are looking for a blue and white wire per Technical Support , go to the very bottom and look up your vehicle by year.

I'm pretty sure I've got the VSS lead right.

From Rostra:

VSS Wire: Transaxle 3 Pin Plug or Under Coin Tray Black Connector
VSS Wire Color: Red/Yellow

None of the VSS leads are blue nor white, but there is a red/yellow one, which is the one I tapped.

My bad, on the vss, was looking at celica. Hey, I have one of those meters

Ok, so the only way to differentiate the injector leads is by left v/s right? No color cues? You willing to try them both if necessary and let us know which one works?

Having gained a little more experience, I'm starting to like the green displays more myself. They seem more readable even when hot. Need to do a little homework before changing recommendations though (check prices/temperature ranges/availability).

I fixed my issue just by creating a new mpguino file, so that's good. Unfortunately I can't find through board tact switches, so it might take a while to get the actual thing going and happy.
