IMPORTANT: enter the case-INsensitive alphabetic (no numbers) code AND WRITE SOME SHORT summary of changes (below) if you are saving changes. (not required for previewing changes). Wiki-spamming is not tolerated, will be removed, so it does NOT even show up in history. Spammers go away now. Visit Preferences to set your user name Summary of change: My trigger settings are here: MembersPage/JoelZernask/TriggerPage As my Genboard v3.3 seems to be installed (see MembersPage/JoelZernask), I will now try to dig through the configration. http://www.vems.hu/files/MembersPage/JoelZernask/config.txt http://www.vems.hu/files/MembersPage/JoelZernask/tables.txt Note that you will need to download the config.txt from the box!!! You do this by issuing Manmcd in a terminal program. The response is saved as config.txt. If you don't do this you will have to recalibrate the wbo2! No big problem but a waste of time. In any case I have updated the config.txt file to work with firmware 1.0.36 http://media.vems.se/code/VemsMT1.0.36.zip which is a development firmware. But it significant improvements over the old production firmwares and it has been used for some time. -Jörgen ---- '''New firmware installed.''' I have a feeling that the settings are still not quite right for my specs, because the primary trigger settings show 58 teeth on the trigger wheel, falling edge and the cam sync sensor also shows falling edge sign + many other things. Here is the output of Manmcd -> http://pildid.audiclub.ee/joel/kuubik/config16032006.txt Please review these settings. ''It's supposed to be right, most of the multitooth parameters are ignored in simple trigger mode, but I would still like one of the firmware guys to take a look at the cam sensor settings as they are far from well documented.'' ---- '''Trigger''' '''Primary-VR''' * NOT multitooth * VR sensor (VR primary-trigger HW used; rising edge configured) ** do we know the polarity ? * 4 trigger pins on the flywheel, 62BTDC each cyl '''Secondary-HALL''' * 1 Hall cam sync pulse overlapping the crank trigger pin occuring 62 deg before #1 piston reach TDC in it's work phase. ** '''Rising edge 77d BTDC''' - certainly this one is to be used, so configure rising edge ** Falling edge 47d BTDC. Use the other edge, not this ---- Here are the specs of my engine: * 1989 Audi PT 3,6 liter 32valve V8 * firing order: 1-5-4-8-6-3-7-2 * ignition type: wasted spark * coils: two 2*2 coil packs (Bosch 0 221 503 407) ---- '''Ignition''' Cylinders firing together are: 1 5 4 8 6 3 7 2 The coil packs are connected as follows: EC36-pin35 to Coil 1 EC36-pin33 to Coil 2 EC36-pin34 to Coil 3 EC36-pin36 to Coil 4 Therefore cylinders are wired as follows (see GenBoard/Manual/DigitalOut/Table for driver channel numbers): Cylinders 1 & 6 to Coil 1 to EC36-pin35 drive00 Cylinders 5 & 3 to Coil 2 to EC36-pin33 drive01 Cylinders 4 & 7 to Coil 3 to EC36-pin34 drive02 Cylinders 8 & 2 to Coil 4 to EC36-pin36 drive03 * ignchmax=03 (03..00) * IGNITION OUTPUTS TABLE: h[2]=03 02 01 00 03 02 01 00 ** going from index config.ignchmax downto 0, the drive00, drive01, drive02 and drive03 will be fired, in this order. This spark table can be used, right? http://www.ubernugen.com/vems/17octsparkmap1.jpg '''It's about right for a start but there are lots of redundant loadsites. You only need 20,30,50,70,90,105,130,150,170,190,220,255. Having 12 kPa sites from 20-100kPa will just waste time when tuning the car which is always bad. Bens current spark and fuel tables will be in the tables.txt file I'm preparing -Jörgen''' Be sure to get the base timing (trigger_tooth and igntdcdelay) right. '''Fuel.''' Again referring to Ben Nesbitt's information, adjusted for my specs: sequential fuel delivery for Audi 3,6 V8 PT engine firing order: 1-5-4-8-6-3-7-2 Bosch injectors 173cc Fuel map: http://www.ubernugen.com/vems/17octfuelmap1.jpg Constant for RPM calculation should be 1500 (8 cylinders), right? http://www.ubernugen.com/vems/fuel5.jpg Req fuel is 16,7 in my case (173cc injectors). http://www.ubernugen.com/vems/fuel6.jpg Here are Ben's trigger tables. How should I fill the first one on my 4 pins setup? http://www.ubernugen.com/vems/mt10.jpg This one should apply to me as it is. http://www.ubernugen.com/vems/mt11.jpg Is this h[0] table correct? http://www.ubernugen.com/vems/fuel2.jpg ---- Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
