Anyone using serial output from FJO WB?

[67SS509]

The GenII should work fine, we have the official protocol for those. (Its the GenIII that we had to reverse engineer). However, I'm pretty sure you need the latest FlashScan firmware to connect to the FJO devices.

If you have the latest firmware (V2.06.16) and hook it up and it still does not work check for these things:

1. Make sure the orange LED (second LED from the left) flashes periodically when the FJO is connected. That indicates serial data is being received by FlashScan. It flashes once about about 3-4 seconds.

2. If the LED is flashing but you still get "Controller not found", please select the option: Scan Tool->Scan Options->Save Trace File. Then copy the saved trace file from FlashScan to your PC using EFILive_Explorer (part of the EFILive V8 software) and email the trace file to me at paul@efilive.com

Followed all the steps as presented by Joecar. Starting to feel pretty good that maybe I can put this together. Still got the "Controller not Found" again today but the 2nd LED is flashing every 4-5 seconds. Trace file to you is in the "e-mail".

I've got the trace file, thanks.
I'll look into it and get back to you if I can see anything useful.

Its all good, the trace shows you are receiving valid wide band data in the range 13.2 to 14.2.

The wideband data is transmitted from the FJO GenII device in the format:
0x31 0x34 0x2E 0x32 0x0A (14.2)
0x31 0x34 0x2E 0x30 0x0A (14.0)
0x31 0x33 0x2E 0x39 0x0A (13.9)
0x31 0x33 0x2E 0x35 0x0A (13.5)

Which means there are actually 5 bytes per sample. Because we do not have a gen-II device to test with here, I could only implement the interface according to the specification provided by FJO.

Unfortunately the specification from FJO stated there were only three bytes per sample. Despite my repeated requests to clarify whether or not the decimal point (0x2E) was part of the frame and whether or not there was a frame separator character such as the 0x0A, the FJO technical guy(s) were not able to provide that information - maybe they just didn't understand what I was asking for. They kept on saying the data was 3 ASCII characters in the format X.XX, which is difficult to understand given that the example "XX.X" is actually 4 ASCII characters.

Anyway, now that I have a real world data sample from the gen-II device I will fix the FlashScan firmware to read it correctly.

Thanks Paul! Does this mean there will be a new revision to the firmware or will I be getting something from you to patch mine?

I'll send you a private update as soon as I can.

The timing right now couldn't be worse, I've just upgraded the development machines to Win7 (finally got rid of Vista) but messed up the de-licensing/re-licensing of our embedded development compiler software. I have to wait for the manufacturers to reset our licenses in their license database which won't happen until next week.

So until then I can't actually fix the problem... :(

Win 7 >>> Vista. Good call, Im waiting to buy W7 Ult when I get home for Christmas. Gotta love Microsoft hookups!

You actually bought Vista?
I thought you guys where smarter than that.
Who knew Vista would have such a short life.
MS should give everyone that bought it a full refund towards the new OS.

Yup, paid for in full and no discount on the upgrade to Win7

Thanks Paul for a job well done! Got the revised firmware from you this evening and installed it. Took a few minutes to realize I had to go back thru the V2 settings after the new firmware was installed. Now it displays the 02 reading on the LCD screen and logs correctly on the dashboard and BEN map. I am one happy camper for this accomplishment. I've got a day scheduled on the dyno tomorrow and this makes it perfect timing.
