Hi,

Apologies if this has been covered before. I have a Brutale 1078rr (2009 model) with a IAW 5SM ECU. The Brutale is fantastic, but the notoriously snatchy on/off throttle is a pain. I really enjoy working on my bikes and learning new things in the process, so at least for now I'm not going the more expensive Microtec, Rexxer, etc route to clean up the fueling and the ignition. Instead, I thought I'd try and find a way to get into the ignition and fuel maps myself to try and clean up the throttle response, lower the fan temperature, basically just play around and learn a few things in the process. I've done a fair amount of research and managed to download my OEM bin file from the ECU, got the correct .xdf file for it and have had a look at the maps in TunerPro. Where I got stuck was writing the updated bin back to the ECU. I'm not confident in the tools I'm using and even though I had someone correct the checksum, I'm afraid that I still might brick the ecu.

This brings me to my questions about JPDiag. From what I can see, the paid version can obviously read and write to the 5SM ECU reliaby and with no issues.
- Once it downloads the file from the ECU, I assume it puts it in a .ddg format as opposed to .bin, correct?
- So once I have downloaded the .ddg file, what am I actually able to do with it in the paid JPDiag version?
- What functionality is available in the paid version?
- Can I view and change maps, lower fan temp, etc?
- If not, then is there a software similar to TunerPro which works with the .ddg file (like TunerPro does with a .bin) and allows one to update fuel and ignition maps, so afterwards one can write the updated .ddg back to the ECU safely with the JPDiag writer?
- I assume if any changes are done to the .ddg file, the JPDiag writer automatically corrects the checksum before it writes it to the ECU?

Basically I'm looking for another route to be able to change the ignition and fuel maps a bit and then SAFELY write them to the ECU. I already have the correct cable set up and JPDiag can talk to the ECU, and do everything that is available in the free non-paid version.

Some help would be greatly appreciated.

ok many questions i'll reply one by one
JPDIAG is only the diagnos software , the paid version unlock the limit of 5 bikes for diagnosing more bikes.

you are talking about the reader free and writer tool paying because it can do much more than write , it can make make a lot of tunes on the flight mainly for 5am and 59m ecus.

- Once it downloads the file from the ECU, I assume it puts it in a .ddg format as opposed to .bin, correct?

yes it read in ddg format

- So once I have downloaded the .ddg file, what am I actually able to do with it in the paid JPDiag version?

you can edit the ddg with my map editor (free as well), it's really basic but really easy to use and find maps once you are use with it

- What functionality is available in the paid version?

well for 5sm ecu not really much than write option , and possibily some tunes like remove lambda ,change fan triger, change rev limiter

- Can I view and change maps, lower fan temp, etc?

those options stated upper really depends of you software version , it's fully automtated . if supported the green ligth of the option will be ticked to green when you will open the file.
to see and edit the map , you can use the mapeditor

- If not, then is there a software similar to TunerPro which works with the .ddg file (like TunerPro does with a .bin) and allows one to update fuel and ignition maps, so afterwards one can write the updated .ddg back to the ECU safely with the JPDiag writer?

the map editor yes, the writer support ddg by defaut but also bin format

- I assume if any changes are done to the .ddg file, the JPDiag writer automatically corrects the checksum before it writes it to the ECU?

of course the checksum is recalculated

Great, thanks!

I think I'll give the reader, writer and the mapeditor a try.

Can I use the writer to write to the 5sm ECU a bin file modified in another software like TunerPro? If yes, will it correct the checksum in the bin before it writes it to the ECU even though it wasn't updated in your Mapeditor?

Can I use the writer to write to the 5sm ECU a bin file modified in another software like TunerPro

yes you can , and the checksum will be recalculated.
but there is still a risk , if you write data outside the map area with a wrong xdf file , you can corrupt the firmware . in the worse case you can brick it

Ok great, thanks. I should have the correct xdf - I got it from OldSkull Tuning and it's specifically matched to my ECU.

Ok, I want to have crack at and see how it works out. How can I pay you for the non-free writer? Also, were can I download your Mapeditor software?

i will send you all file you need once you purchase it by paypal
you can use the donate button in jpdiag or use my email as recipient

Perfect, thanks. Will do. Remind me please - how much is it again?
