Hi everyone, I've searched high and low for this and can't seem to find a definite resource such as a table that compares ECU model (59M + 5AM) to Exhaust (OEM, DP Assymetric Half, DP Assyetric 57mm, DP Full 57mm) and then points that to a P/N and Map. Its possible that some of these combinations don't actually exist but I've struggled to find my own use-case: 2003 999S with a DP assymetric half-system. I have the OEM 59M ECU but what's the ECU P/N for the DP part or the code for the map file?
This took months to create https://jpdiag.akress.com/modelselect.php The map ref is usually the part number (as always some bikes are exceptions to the rule. Just put 999 in the search box. The DP maps start with a 9. You will find entries where Termis are fitted with a stock ECU 999s termi Ecu: 979000167 HardwareVer: IAW59MHW010 SoftwareVer: 0130PD36 999S 2004 DP57mm Full line Ecu: 979000204 HardwareVer: IAW59MHW010 SoftwareVer: 0130PQ14
So for my case this would be: 999s termi Ecu: 979000167 HardwareVer: IAW59MHW010 SoftwareVer: 0130PD36 Next question is, how do I flash my 59M with map 979000167 ?
If you have the cables that work with Guzzidiag then use Guzzidiag writer https://www.von-der-salierburg.de/download/GuzziDiag/IAW5xWriter_V0.24.zip and the map bin file on this link http://www.desmo-riders.fr/manuals/999S-2004-979000167-IAW59MHW010.bin
Awesome, thanks Map file flashed and all works well! Now just need the roads to dry out in order to see what difference its made.
After all the crap weather we've been having over here and despite curfew restrictions, I've finally managed a short 15min ride on the bike. Initial thoughts of the DP map for the 999s are disappointing. It seems to have lost all that fat and juicy low/mid range torque but does rev out faster.
The 999 ecu's aren't simply plug n play, neither are reflashes. The TPS will need a reset in the very least, but the base idle mixtures will need setting as well to get he best out of the map itself. It needs a "datum" to work from and without the reset and trimming, the whole map is off.
Thanks! I take it that for proper trimming a CO2 analysis tool is required? I have the original ECU map that I saved previous to the re-flash.
I invested in a Gunson Gas Analyser for CO setting. A 1/4” BSP tail fitting allows the reading to be taken from the gas take off ports before the exhaust, or with the termi set up (no cat) just place in the exhaust. 14.7:1 is perfection. https://haynes.com/en-us/tips-tutorials/what-afr-or-airfuel-ratio-your-car
I can get access to a Gas Analyser at my local "friendly" (non Ducati!) gargage but before going down this route, I wanted to get feedback on the expected differences in feel between the standard and DP map. In other words, is the DP map timing/fueling designed for more peak RPM thus sacrificing low/mid range torque?
Not much joy with with the 59M maps on the GuzziDiag site, tried a few and the values they come back with for the fuel/map table are gibberish.
Not one to give up, I used the old ECM tool in order to compare both maps Here's the percentage change on fueling based on the TPS value vs RPM. These results would suggest OEM 999S map runs a tad rich and the DP 999S map leans it out a bit. These are the ignition advance changes on the 999S DP MAP:
Went out for another run and even at WOT the "go" isn't there. I'm thinking that to get the best out of this map then whole shebang has do be done from the ground up: Valve clearances Throttle Body sync Idle mixture (baseline for the map) TPS sensor (making sure linear TPS matches current revs) @nelly @chrisw I think 1-3 would probably explain it better than 4 but I could be wrong...?
