Hooked up RPM and TPS on the analogue inputs and reading data, so far so good. I see some difference in AFR between front and rear, and I've been reading about the rear cylinder need a bit more fuel as it runs hotter. The question I have is, are the two cylinders supposed to read the same AFR, i.e. you give the rear a bit more on the map, but AFR should stay equal to the front as it burns hotter? Or, are the AFR reading supposed to be richer on the rear?   Natexlh1000 Posted on Sunday, October 16, 2016 - 08:45 pm:        You basically made your own 2010 bike. Those had sensors for both jugs. Perhaps you could find a map for that ECU and use that as a starting point?   Phelan Posted on Monday, October 17, 2016 - 01:31 am:        No. AFR should be richer on the rear cylinder, as heat is a non-factor for the reading itself. What tuning software are you using? If ECM Spy (and presumably Megalog viewer as well) you can view and edit the target AFRs in Megalog. If you are using ECM Spy without Megalog, you will have to save your EEprom and rename the file extension to .txt, then you can view and edit the target AFRs, but be aware there is spacing format, and the table is flipped. After viewing/editing, rename the extension back to what it was and burn that file to the ECM to input the changes.   Pagprivat Posted on Monday, October 17, 2016 - 09:10 pm:        I've been using ECMspy to edit, but logging with the LM-2 (with dual wideband) and the logworks program from Innovate to read logs. Then I've just edited the cells that need edit directly in ECMspy. The method works pretty good and I'm making progress on the maps, I was just wondering as to where to set the targets on front vs rear. Any idea of how much richer it's common to leave the rear? As the CL reference under normal operation would be the NB O2 on the rear only, (this is a 2008) I was planning to leave this as close to stoich as possible to avoid the system adjusting the AFV too far off when learning in CL...   Sagehawk Posted on Tuesday, October 18, 2016 - 04:31 pm:        Which version of spy are you using?   Pagprivat Posted on Tuesday, October 18, 2016 - 08:15 pm:        Latest version, the one you have to make a donation for each ECM firmware you need activated for.
