Summary of change:
Maybe I misunderstood on phone. Is this an audi with '''24+1 "nissan-like" trigger''' ? Move content under MembersPage/PeterJensen/.... if appropriate. ignchmax=03 next_trigger_tooth=06 And reference teeth: h[1]=00 12 0C 06 ... ---- '''Ignition outputs''' 4 ignition level outputs needed to fire external ignition amplifiers See GenBoard/Manual/IgnitionOutput '''Choose 0,1,4,5 channels''' which allows the widest set of ECUs (0, 2 or 4 IGBTs) to be used * when testing something with borrowed ECU ** nr of. EC18 analog inputs have been extended over time. Always check carefully not to apply 12V (or anything outside 0-5V) to any analog input! * or ordering ECU with different IGBT-number than intended * or ordering ECU to be used with more than one car Firing order is 1,3,4,2 '''Recommended order''' (list actually travelled '''upwards'''): * cyl1: ignch0 EC36/.. * cyl2: ignch5 EC36/.. * cyl4: ignch1 EC36/.. * cyl3: ignch4 EC36/.. '''h[2]=00 50 10 40 ...''' With this ignition output setup, you can * use assembled box with 0 IGBT, 2 IGBT or 4 IGBT * with a missing tooth wheel you are able to '''limphome''' without camsync (disable camsync, shorten dwell and enable igndualout). ** Only to avoid towing. This is not good for running high-power (COPs would fry at the worst time when you are as far from home as ever ! Yes, COPs somehow always find the most inconvenient time if you abuse them) ** if the engine family is always equipped with a "coil-type trigger" (no missing tooth, so limphome without camsync not possible anyway) you can choose h[2]=00 50 40 10... for readability. This order is easier to verify and rotate without a paper reference '''In any case, keep written notes about subsystems in a thin paperbook''' in the glovebox. BAD order, do '''NOT ever think about h[2]=10 20 40 30''' !!! * cannot use ECU with 4 IGBTs * cannot use ECU with 2 IGBTs * can only use ECU with 0 IGBTs * limphome without camsync not possible with any primary trigger wheel * wiring instructions are not simpler in any way, as the EC36/xx pins will not be 1-2-3-4 or any "order" anyway * if you choose a set of outputs (this is a very bad set), than you make the ignition output order look good (NOT cylN to ignchN !!!). * you only make the wiring once, following '''written plans''', looking at the EC36/xx column (not the ignch column) * on the other hand you might verify ignition output configuration dozens of times ** even rotate it when trying to start. Or when upgrading from 1.0.x to 1.1.x if the reference tooth starts with 0 (as recommended). Making a standard is good. But making something standard that is a bad idea for any setup is not good. ---- '''Trigger''' 24+1 VR ? '''primary''' ? VR ? '''secondary''' ? VR as well ? If you have 1 camsync pulse, but 2 camsync sensors, say 360 crankdegrees off (as on many nissans), you only need one. Try to mark it. * with a supposed camsync problem, using the other camsync sensor is an option: just need to rotate ignition output order cyclically.
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
