Ficht 175 unreadable EMM transfer questions

[kapco]

I have a 99/00 Ficht 175 and the ECU has issues (code 15, not fixable). It was purchased in not running condition for a song. So I found the same part number ECU of fleabay. I hooked it up just to see if it would run before going any further with it. It starts and runs fine...little stumbly on initial throttle but revs up. I know that the injector coefficients on the swapped ECU are not correct as they are for the injectors from the powerhead it came from and they have to be matched. I wont be running it like this as here is where my question comes into play. I managed to read the old ECU once and get a printout of the coefficients and serial numbers for each cylinder but now I can no longer read it as it has a communication error.
Using the E-Diag sofware can I simply perform a "injector replacement" on the injectors and use the information from my initial read of the original ECU or is there other information that is needed to transfer over also? I can set the parameters for timing, idle, etc the same. I just worried there is other data that needs to transfer so that I cant manually change over. I am wondering if there is fuel tables similar to an auto computer or if the coefficients are the only data.
I do know that the engine info wont match (serial number, model#, etc) but is that an issue from an operational point of view?

The ideal way would obviously be to copy over the one ECU to the other, but since I cant read the original anymore thats not an option.

It all depends on the EVDiags software version you are running. The newer versions do not allow the direct input of the parameters into the appropriate fields.
On version 4.5, you can cursor straight to the field you want to change, and input your numbers.

As far as the other info/data you are worried about...(fuel tables, etc)...no such thing on that early Ficht.

The only thing you will need to do is the coefficients.

You most likely will not be able to re-create the injector file and read it in that way. Nor will Evinrude provide the injector files for you.

You will best be served to scour around for a ver 4.5 Evdiags.....which I have.

Where are you located?

Don't waste your money working on that as parts hard to find and no support from dealers. I get tickled when people think they can fix these motors when OMC spent tons of $$$$ and couldn't...

 

[kapco]

Daselbee thanks for your response. That's what I was looking for. I'm pretty sure I have a recent version...I want to say 5.3 but I'll check. I think I was able to make the changes but I didn't proceed until I was sure that's all I needed to do. I'll give it a try and see. I am located in Manitoba Canada. I am wondering if I can make a dat file using notepad. Can the Dat files be opened with a text editor? I'm wondering if the Dat file is just the coefficients seperated via commas. If so I could make them. Wish I had a dat file to play with.

Fastbullet- I was looking for a 175-225hp motor to power a Mastercraft Barefoot 200. If you can find me good running direct injection motor over 150hp with about 300 hours of freshwater use only for less then $750usd with controls let me know. Seems to me that with a few mods and a good understanding on maintanence these motors can be decent. They have there issues (in this models case....ECU) but If treated properly and fix the issues that cause the problems I have read many people getting lots of life out of these. I am not saying they are the best motors but for my budget and where I go....will do me fine.

Daselbee- I just came across your etec 75hp EMM on a 90 thread on a Google search. Dat file question answered.

 

[Faztbullet]

Sorry mods are patches for these year models....but if you need a 99 powerhead have a fresh rebuilt one with 0 hours cheap...

I checked my software version..,...5.7.6
If anyone has any dat files from my vintage (DI pds injector) I can play with? I have a few ideas on how I may be able to make it work other then trying to dig up version 4.

The first is I would like to see if I can open the dat file in a hex editor and figure out how its constructed and either make a dat file or change one to match my injector data.

The other is although I don't have a hand held scanner, usually they just simulate a keyboard input. I am hoping I can put the injector info in a text file in a character string format a 2D scanner would out put and copy it, then when it asks me to scan it I can just try hitting "CTRL+V" and it may past the data in as if a scanner spit out the data. Its raining out right now and I don't have a place to test it indoors as my garage is filled with another project at the moment.
Soon as the sun shines i'm going to give it a go.

The older .dat files were indeed man-readable ascii files that could be created with a text editor.
The new .dat files as I described in the post you mention are coded in some proprietary Evinrude code algorithm.

I do not know the order in which the coefficients are positioned in the simple text string.

It is possible that it is the same order for the 2004 and earlier DI engines that use a Datamatrix encoded bar code that can be read with a smart phone.

If you read out one of those datamatrix codes from the serial number label on an injector, it shows the coefficients and the serial number
in a comma delimited single line string. Just don't know the order.

If all else fails, send the emm down here, with the coefficients list, and I will program them into the EMM with my ver 4.5 software.

All this is a result of the EPA forcing Evinrude to bullet proof the injector programming to keep hackers from hopping up their engines like they do with cars now.

If you can wait a day, I will scan an injector and post the data string that is encoded as an example.

 

[kapco]

That would be awesome, I can wait as the rainy weather and my day job (and night lately) here is keeping me from working on it anyways. Rain and laptops don't do well together,
If I can get an example of the order and how it looks in a text file I think I am home free. My guess is its in the order of the entry fields.

 

[daselbee]

The scanned Datamatrix code from an injector off of a 2004 225 DI scans like this:

33,257,1108,24007084,03204050339183

Inigma, the code scanner I use, says it is text data. Some of these Datamatrix codes will launch you to a website, etc.
This is simple text.

The spacing is exactly as it scanned. The last field is the injector serial number.

Awsome!! Thank you so much!!!! I am hoping to hook up to my motor tomorrow and see what I can accomplish.
I actually worked on the old ECU today. I removed the bottom cover and removed the silicon potting. Turns out I think there was a couple broken solder joints on the microcontroller legs. I got my soldering equipment fired up and re soldered the microcontroller and the memory chip just for kicks. I am going to put that ECU back in and see if I can read it. If I can I will see if it runs. Might have fixed the original ECU. I am not holding my breath but worth a try. If not, back to my plans with the replacement ECU.

ok. My injectors are barcode only, so it may not take a scan, ill find out tomorrow.
Just to confirm the order matches what I think is correct. Is this what your matrix looks like?

 

[daselbee]

Barcode ONLY label on the injector is a representation of the serial number ONLY. That barcode does NOT have the injector params encoded.
During this era of Evinrude Ficht engineering, the injector params were supplied with the injector on a floppy disk.
Then the 2002 thru 2004 family of injectors came out, and the parameters are encoded on the label.
THEN.....when ETec was introduced, the .dat files are encoded (no manreadable info) and the tech is expected to download from the net.
They also implemented a checksum for deterring hacking.

The Datamatrix code is as your pic shows. However, there are different versions of the Datamatrix code, and I use the name sort of generically.
They could actually be a QR code or some other variation of the square code style you show.

You apparently generated that datamatrix code, because it scans as the exact numbers I provided above.

 

[kapco]

Yes. Mine is serial number only. I put my data into a 2d code generator in the format it would need to bi in if it was like the type you have. If I need to I may be able to use the scan function and scan the codes I made and it may enternter the data. Been super busy and still raining here. Tomorrow supoosed to be decent in the afternoon so hopefully I'll be able to play with my laptop outside and see where I am at. I appreciate the responses. I'll post my findings incase someone else ends up in my situation also.

Big Thanks to Daselbee for the injector scan format. I was able to put in the coefficients in using a simple copy-paste from a text file. I could probably have just typed it in but too much chance for an error. This way the data was copied from the PDF report, and pasted into the text file and formatted properly.
Worked like a charm.

On another note I managed to repair the original ECU. AS I posted above the re-soldering appears to have worked. I can now read the ECU again and seems to run fine with no codes. I will now keep the ebay ECU as a back up as the injector info was changed to match the original and it runs well also. (Test stand running, in water test TBD)

Now to get it ready to install on the boat. Going on a Mastercraft Barefoot 200. Anyone know what this water port is on the rear of the block? I am assuming it was used to run a water pressure gauge? Cant see anything that would hook up to it.
