Polaris Ficht Fuel Injector data encoding, EMM reading/writing

[lilman573]

You are tryying to get me divorced..... are you able to read the barcode to show what the injectors should be?

Any links/threads that talk about ficht injector bar code reading? Inquiring minds want to know

Pretty sure the codes can be read by any smartphone app. I don't have those injectors anymore to try or I'd pull the numbers off to see.

With his digital wrench setup, he should have all the I formation he needs!!

Yup! Just downloaded qr droid for free, snapped the qr code from one on eBay right now.

That should be all the info you need right?

Yes ive already gotten the data off the injectors. I cant figure out how to get it into the emm though, and really havent had the time to put into figuring it out.

BTW that only works on newer injectors. I have a 1200 set from 01 that is encoded ECC140 and the datamatrix scanners today wont decode them.

I might be able to help with a 2d scanning system, if needed.

That's not so much of a problem. Hand scanners can be had on ebay to read the old data for $40 or so.
The problem I'm running into right now is getting the data I already have into the EMM. I played around with it last night for a bit. I was able to load up DW and sniff the serial bus to capture data. It's a hex data transfer with what appears to be the first couple bits telling the EMM if it's a read or write request. I ran into some wonkiness that I suspect may be due to using a usb to serial adapter in that my sniffer program kept seeing sent and received data even after the program was closed.
I've had success with reprogramming devices on the GM DataBus in my vehicles and the format looks very similar to the ALDL system used there. Hopefully FICHT wasn't using a seed/key system and everything is in the open.

*Ideally* if someone could figure out the encoding of the injector data on the floppy disc that comes with the injectors, that would be an easy way for anyone to DIY at home. That was my original idea, but it appears the data is in a Unicode binary format or something. If anyone wants to have a hack at this let me know. I'm willing to share what I have so far. The injector data files came from Keith so I would just want his blessing before I share them. (I don't see how it could be an issue, but it's just the right thing to do)

Wait, i thought you could do the injector replacement right in digital wrench?...

*If* you have the .dat file with the coefficients in it.
