Re: Common Rail MC33816/PT2001 dev board - 4 injectors GDI
I recall some concern about the transition time as well. AKA faster or slower devices may cause issues. I recall this concern was an unknown, so if you make a change I suggest to make low QTY order and test before committing to larger QTY.

Re: 2006 Volkswagen Passat 2.0 Turbo GDI test mule #64
A tip, if you put the security lug back on, put all of them on one wheel, like the rear passenger side. Then you mostly don't care about the stupid adapter.
Cool to see progress. Thanks Scott for the recent kick to get it moving along again.

Re: 2006 Volkswagen Passat 2.0 Turbo GDI test mule #64
In my scope capture, the vertical scale is questionable. I don't trust it because I didn't calibrate verify it first. It was a quick measure and seemed to be in the ball park. I think Matt's capture says 2 amps. The big thing is that I think a 4.5 amp driver will be ok.

Re: 2006 Volkswagen Passat 2.0 Turbo GDI test mule #64
In this post, I measured OEM in the hold pattern was about 4.5 amps. The yellow trace was 2amps per vertical division. So it would appear the hold voltage is below 12v.

Re: Common Rail MC33816/PT2001 dev board - 4 injectors GDI
Did we have some small change to the internal firmware? From memory I think there was a small change. Also from memory the current firmware would work on both. Something like if.serieal number blah then X instead of Y.
I think we expect them to be interchangeable.

I recall timing for both fuel and spark are a bit different then 2 stroke, but totally doable if it's detailed enough for developers to implement.

Perhaps change the current sensor? It seems you just trying to sense the amps. See below video it details the use of a low cost board you can get on ebay.

Re: ECU high-level programming
If we integrate into scratch, we could potentially attract many kids they would work for free.

Scratch is a fairly decent graphical / easy to use programming environment. It might not be that far fetch of an idea to use as a higher level programming environment.

Re: ECU high-level programming
Most OEMs have tools which allow then to specify high level stuff. They spec number of cyls, injector flow rates, etc. The tool then splices together the code they need to operate the engine. I recall Freescale has one that can be downloaded for free.

After the op-amp with a 5V input, you should see something more like 2.5V. Can you measure AV5 at the stm32 pin? What voltage do you get there?
