Summary of change:
As my Genboard v3.3 seems to be wired up (see MembersPage/JoelZernask), this page is about the configration. ---- 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) * note that you can get better advices if you publish mcd and mct dump, and the used firmware version ---- '''Trigger''' '''Primary-VR''' * NOT multitooth * VR sensor (VR primary-trigger HW used; rising edge configured) * 4 trigger pins on the flywheel, 50 degrees BTDC each cyl ** each pulse 50 degrees BTDC (+/- 1 degree). '''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 ** '''QUESTION:''' What rising edge degree should I mark in the MegaTune secondary trigger menu? *** it does not matter, as long as it's always between given 2 cyl's spark, the actual position does NOT matter Problems faced with the trigger during the installation process are here: MembersPage/JoelZernask/TriggerPage (chronologically listed, lots of BS) ---- '''Retard why ? Currently the engine is running, but the ignition is 15 degrees too late (even if the primary trigger degree BTDC is marked "0"). * Can this be cured by changing the secondary trigger degrees? ** no. adjust ign_tdcdelay=0x64 (decimal 100, that is 50 degrees between trigger to TDC) * see MembersPage/GaborRacz/NewAlsLaunchAndOthers to disable ALS originally so you're not tricked by bad settings ---- '''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: 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 ---- '''Fuel''' Sequential fuel delivery for Audi 3,6 V8 PT engine firing order: 1-5-4-8-6-3-7-2 Bosch injectors 173cc Constant for RPM calculation is 1500. Req fuel is 16,7 (173cc injectors). ----
