Yes, I had the BJM done prior to replacement of the ECU
Also, it seems that I heard the new ECU wasn't suppose to change the stock CO settings?
The settings are whatever the "new" ECU was set with from the Factory. It has absolutily nothing to do with a particular bike or what settings the "old" (original that the bike came with) ECU.
The above statements seem like they go against all I have heard about CO settings being setup for specific bikes or specific vin series...
The ECU settings are generic, that is they are something the Factory can live with. I really dont know, but I would not be suprised if the Factory is only required to test a certain percentage of their production runs. If this is true then having a standard setting for ECUs makes sense. The settings aren't perfect but are "good enough" to pass emissions. That would explain the reason so many are the same and at the same time other groups are different. It may be driven by the runs and testing procedures.
If your original ECU was -10, 8, 8, 11 and the new ECU was at 5, 18, 18, 21... It seems like a big change in CO settings(was this an error on the dealerships service dept. side of things?? Or NOT??)...
No error by the Dealer. I doubt they have ever set the CO2 settings when delivering a new bike but it does appear, as you stated that there could be a big spead in one's orginal settings and what may come in a replaced ECU. Some members have reported a lower mpg since having the new ECU installed. Maybe the different settings cause this when also coupled with the altitude fix. I don't know. I also don't know if altering the CO2 settings has the ability to decrease your mpg.
I thought the CO settings were suppose to remain the same??
Well, in my case they did (not taking into account the amount I orginally "changed" my settings from stock). I have since gone back into the diag. mode and "bumped up" my settings an additional 5 across the board. This is where my "shooting blanks" statement comes from. Without the proper way to test what the CO2 readings are in each pipe I'm just guessing or shooting dice, whipping the bishop, spanking the monkey or whatever you want to call it.
There is a very good thread on this (not whipping the bishop) by a member in Germany. I have not found it yet but I keep searching. It brings this whole crackpot method of accross the board adjustments to the CO2 settings and what the Factory settings don't really do to balancing the levels. It is the best explaination about how to achieve the results correctly.
Anyone have the true scoop on this??
