Re: SBF - Dual EDIS8 modules with Ford 4.6 COPs

I've read somewhere, EDIS monitors coil flyback voltage.

How do the coil primary and secondary resistances compare?

How about primary current and duration?

Re: diagnosing and inspecting v8 v10 Ford Excursions' sensor readings

It is correct that 'normally' functioning engines operate is a fairly typical range across the board. Clear fault codes alone can't rule out some issues, there are many failure modes that won't be monitored by the EEC. Things like oil and water cross contamination and wear. You could do used oil ana...

Re: diagnosing and inspecting v8 v10 Ford Excursions' sensor readings

Side note-
MAF is checked against speed density or if temp goes down alpha N.

It's covered in the Ford strategy docs...more reading.

If the sensor values are outside of an expected range reative to each other, then a fault code is produced.

Re: Project on Reverse Engineering binaries, assembly, coding and learning more about the ECU

12V or 24V for power supply, the chips are 5V I believe.

The data streams are a mix of voltages depending on which protocol standard.

Check out the documents on the Elm site.

As paulie says, the free CBAZA def has a poor reputation. The flag function can be whatever the definition creator decided to do.

Re: 460 Mass Air Binary Editor Questions

Who's strategy file are you using?

1. Temperature.

2. Different idle speeds for different conditions.

Read the ford strategy documents. There is gufb, cdan, lhbh1 and crai8 that can be found and downloaded.

Re: Trying to Learn and convert different eec-v maps

LP4-322 OR 323, that is a hardware code. The EEC hardware is different, you need to identify what is different in detail to understand if you have a chance of success. Tuning requires disassembly of the binary file from the PROM. Then create a definition file for the tuning software so tune changes ...

Re: Project on Reverse Engineering binaries, assembly, coding and learning more about the ECU

I think default naming it LSO_Ch#6 or similar avoids it being incorrect and misleading for a large number of bins. The user can rename to suit any particular bin. Not seen DUCE in 32kb or smaller bins, so that could be used to change the default name. Alternatively accessing of the DUCE memory addre...

I was looking at AA 2039: xorb R2, 40 . . so I guess 40 = 0100 0000 while R2 = 0000 0000 so xorb -> R2 = 0100 0000 .. so I suppose that's bit 6 == LSO_6?

but from program code, i'll be able to understand what packet I get from the DLC is related to which engine function right? Yes But I don't see the manuals defining what the word "MB" is. Mode Bit... short indexed or long indexed. I reckon i should just start grinding and say fk it. Go for it.

I've read some general EEC books and, correct me if I'm wrong, that most data signals flow from the sensors to be converted at the AD convertor before being accepted at the I/O of the microprocessor to be processed and output. Correct not much happens in an EEC until inputs are read. Generally... D...

The cam sensor IS the TFI distributor in the case of TFIs. I don't know if any TFI applications had crank sensors too, but I doubt it. Although I can't say that with absolute certainty. A cam sensor, in a 36-1 crank + cam sensor config, is sensing Cyl 1 only to provide sync for injection timing. Th...
