Visit Preferences to set your user name Summary of change: Hi I am working on a BMW 635 csi '79 ---- I am going full sequential ignition and injection in the future but for now wasted spark is OK. All hardware is ready now only camsync not. For now I want to run wasted spark using COPs. But the inject and ignition outputs are a mystery for me. '''Q1''' I read I need to configure ign_dualout but I cant find where?? '''A''' I asssume you are running the latest released firmware/megatune package ? If not, get it from [http://www.vems.se/UserFiles/File/VemsMT1.0.36.zip here] (unzip and run megatune) then if you take a look at settings -> ignition settings, you'll find the option "Dual output mode"; enable that. After that set up the ignition channels in settings -> Ignition outputs dual setting screen. - DB <code> global.h: uint8_t ign_out; // EDIS:0x0? dummy: 0x7? disable:0xff bit1: ign_dual_out bit0: invertout </code> After setting it, you can verify in the mcd dump that ign_out=72 (not 70, that is normal dummy-ignition). Don't forget to wire the ignition-outputs sufficiently: the paired outputs must be neighbor ign-channel numbers such as 1 and 0 (or 7 and 6, etc...). '''Q3'''I do not completely understand the text above, I paired the outputs but what do you mean with global.h and mcd dump? ---- I'm now testing the ignition coils and al work well when using the keyboard command mdnxx, I get a 2 nice sparks (thanks DB) for the 3 cell numbers. but when I crank the engine nothing happens even the spark advance in megatune stays red ad the background en says -1.7 degrees '''Q2''' What is wrong please see my config '''A''' I guess you dont see rpm while cranking either (or irratic rpm numbers) it seems you have your trigger tooth and another trigger tooth swapped in config. Since you have a 60-2 on a 6 cylinder, another trigger tooth should be 60 / 3 = 20 (14 hex) trigger tooth should be adjusted so that ign_tdc_delay is around 60 degrees. (6 is usually a good starting point) [\ MembersPage/Bvd/Config] ---- The input triggers: original 60-2 wheel (BMW e34 ’90) Camsync: [http://www.cy-sensors.com/Vane%20Sensors.pdf Hall-Effect Vane sensor] Camsync sensor position with the info on GenBoard/Manual/InputTriggerCamSync I made the following drawing to figure out where the camsync must be placed http://www.vems.hu/files/MembersPage/Bvd/campuls.JPG So if i turn the crankshaft to 150 degrees before TDC of cilinder 1 the Hall sensor mounted on the camshaft should give a reset puls. Please correct me if I'm wrong ---- '''See DocsPage bottom for file area to upload images.''' alternatively you can upload the pictures from your computer to another image hosting ("gallery") site like [http://tinypic.com , than copy and paste the url for the image into you wiki page. ----------------------------------------------------------------- Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
