Since others have discovered some issues with the new 051123_catfish2011 map. I decide to do some testing and start a thread about these updates. <http://www.endorphin-express.com/capo/maps.html>.
I tune my Caponord with the 050429 ECU software version with my map tables using the TuneBoy TuneEdit 220.127.116.11 software on my PC. The 050428 ECU software version is identical, except for requiring a purge control valve for the charcoal canister that USA (& maybe others) come with. The 050428 software with my map tables works exactly the same in my Caponord as the 050429 with the same map tables.
Previous testing of the 051123 software + maps seemed compatible with my Caponord. I have not tested this version in my Caponord in a few years. I have been replacing the oem map tables with my map tables in all three of these versions and making them available.
In the links thread ...
This new map vs. oem map comparison sounded very strange to me, so I had to do some testing myself. I am apparently experiencing the SAME strange idle & off-idle throttle response issues you have been complaining about when I download the 051123_catfish2011.hex map. :-( The oem 051123 download does not have this problem.
I have re-built the 051123 map with my tables in TuneEdit and TuneECU, and both cause the same problem in my Capo. Oem tables are fine, except for a sizeable IFT adjustment to get the idle CO to ~3%.
It appears as if *something* in the 051123 software is NOT compatible with my tuned map tables. I do not know what this is, or why. I just know in testing all three maps (050428, 050429, & 051123) yesterday ...
1. My Caponord purrs wonderfully at idle & low throttle positions (at & near idle) with either the 050429_catfish2011 map or the 050428_catfish2011 downloaded. I just get a flashing EFI light with 050428 because I have removed my purge-control valve & canister.
2. My Caponord does NOT run very well at all (at & near idle) with the 051123_catfish OR the 051123_catfish2011 maps downloaded. However, it seems fine above 2500 rpm!
I do not understand why the modified 051123 maps don't perform the same in my Capo as the modified 050428 & 050429 maps. Until I can figure out WHY this problem exists, I'm no longer going to make modified 051123 maps available.
Those who have been trying to get my modified 051123 maps to work, I recommend you try the 050429 map, and let me know if you get a flashing EFI light and/or O2 sensor error code in TuneECU.
I tested ALL of the maps on my map page above in my Caponord yesterday, and they all worked without problems. Well, I didn't bang the rev limiter with each though.
In the links thread & talking about TuneECU ...
Check & let me know if you find any further issues & report back HERE in this thread. Lets leave the links thread to just links please.
In the TuneECU thread ...
The fuel-map work was done "on the road" with a wideband O2 sensor+controller, and in the garage with my exhaust CO meter.
Optimized ignition timing (for the most power in these big v-twins) is TOO MUCH at these low RPMs & throttle settings. You get very abrupt throttle response down there when cracking the throttle open with optimized timing. So yes, timing does need to be neutered in this small area of the map to make the throttle response smoother & "friendly".
So, my "neutering" is from idle to 2000 rpm. Aprilia's was from idle to 6000 rpm.
