Buell ECU firmware update.

[Cooter]

There are several versions of the firmware in both the DDFI-2 and DDFI-3, some of which tend to be a bit 'glitchy'. The most common thing I find (BUEZD, BUEOD) is the AFV will re-set from 100 to a lower value when just cycling the key. Yes, that's very frustrating

There also seems to be that the majority of the fueling programs available (for free) are for the latest firmware version (BUE2D). I'm a do-it-yourselfing cheap ass

There are a few Harley dealers that still service Buells and (for $50) will update my ECU to the latest BUE2D. But none in my area, and because they are Harley dealers, the service department is always backlogged a few months, even for this 10 minute job and they need the whole bike to be there too.

So... Is there anyone who can update my ECM's to the latest BUE2D besides the dealer? Fueling programs can stay with whatever in there now. Can you do it with just the ECM and not the whole bike? All you would need is the BUE2D download and a donor harness....

Anyone??

There was, and then people complained about paying for something that takes a lot of effort and time to figure out... So, he stopped offering his services...

It's on my list of things to accomplish. I know the gist of it...

Although it's off topic. I believe someone should get paid to custom make an injection program (or download firmware updates!), even if it doesn't involve true "tuning" with wideband O2's, test rides, and a dyno... it still takes skill and time to read data logging and write it accordingly. That skill should be paid to those who have it:up:

Alternatively, I can copy/paste existing programs I get for free (from buellmods.com, Buelltooth.com and several members here) that cover 98% of bikes, and I don't charge for that. IMO I don't own the original program (thats out of Pandora's box now), so I feel I don't own it after I install it. I'll give that 30 seconds of my time away for free.

No one is gonna get rich modding the small amount of Buells left or giving advise on a forum. I personally do it because I like this community (mostlyhaha) If someone has a marketable skill or product for Buells... cool! It helps us all out.

I know you (AZ) work hard at hand making excellent Bluetooth dongles and have made a convienent package with a tablet for Buellers to buy for diagnosis and mods. Thanks!! I send people your way as often as I can because I know you're a big presence on the forum and back your stuff up unconditionally. You deserve to be paid for your time and your product:up:

I would ask Tim at IDS about firmware upgrades .

That's a great suggestion! I :love_heart: this place. Thanks

Firmware update will be implemented in the next version of EcmSpy, but will not be publicly available.

I have the same issue up here. Still on BUEZD wanting to move to BUE2D.

 

[Cooter]

What do you mean not "publicly available"?
Not available to anyone, ever?? Or not available with the free version of ECMSpy?

I'm not asking for it to be free, on the contrary ^^^(post #4).

IDS PCMTool already has this capability to update ECM firmware (aka application), If you can get the 142 or later calibration flash for BUE2D...

 

[Cooter]

Nice:up: I will see what that's all about. Thanks!!

wouldn't you just download the firmware from and existing BUE2D ECM and keep it on file?

The problem for me is that there's one HD dealer in the NYC area that can do it. I guess they know this, because the $50 price was quoted as $150, & I refused to be extorted.

Personally, I don't see a problem with someone doing this for the community and charging a small (fair) fee. They wouldn't be taking business away from HD as most of them don't even do it.

So I reached out to Danbury HD dealer and they could do the update for me, all for $50! I went with my buddy this past Saturday & they had both our bikes out in less than an hour, $55 each after taxes. My buddy examined the new BUE2D EEPROM and says there is no difference in Fuel Maps & ignition timings. My bike seems to run better, so what else could have changed that appears to have improved things?

Overall it's a great $55 spent as I can play with all the maps that are available for the most current BUE2D EEPROM.

When they did mine (for $150...) they also made the odometer read in Km instead of miles.
I wonder how much they'll charge me to fix what they screwed up? Sheesh.

I´ve been to the HD stealership yesterday in Sao Paulo - Brazil to try to have the firmware updated from BUE1D to BUE2D. No luck.
I stayed beside the guy doing the job so could see how their computer system works. After reading my bike´s VIN the software prompted with 3 available EEPROMs for my bike as follows:
-M31US282
-M31AU282
-M31BZ251
The last one with the "BZ" as to Brazil is the one already in my ECM. So there was no option to upgrade to a 282 map designed to Brazil. So we tried the M31US282...the ECM flashed correctly but unfortunatelly it did not work..right after flash completed the ECM went crazy and lots of errors came up. Sensor readings were messed and the engine wouldn´t start. Had to flash back the BZ251.

What I found most weird was that the US282 "matched" to my ECM part number as per the dealership software. It did not say it wasn´t going to fit, on the contrary, it estated that my ECM part number was appropriate to that mapping.

Maybe when ECMSPY has the capability of upgrading firmwares I give a new try.
