Summary of change:
''' Stage 1 - Controlling injection ''' Due to signal split difficulties, I skipped Stage 0, and start to wire the car with this stage. ---- '''Harness''' I have disassembled a harness from junkyard, not exactly the same as the original one, but it's from a '98 BMW, connectors seems usable, and have a lot of double-colored wires, relay connectors, fuse houses, etc. Note: * for 3-pole AMP connectors I've found two types, Code I and Code II. They are not interchangeable. (photo soon) * for 2-pole AMP connectors I've seen Code I only. I had difficulties to live both (motronic and genboard) harnesses the same time, since there's no room to wire so much more things from engine bay to the glovebox (small hole on firewall, sealing fits). I removed sealing temporarily, this gives much larger hole in the firewall, but wires have a direct contact to somewhat sharp metal. Since motronic has to go either in Stage 2, I decided to move the whole motronic harness and ecu to engine bay temporarily. Genboard harness will go to the glovebox. I've checked that both motronic and econoseal connectors can be pushed over on the hole in firewall. One small issue : there's a 3 pole connector from main motronic conn. (photo soon) to instrument panel which is vital to work. It contains instrument panel signal, tacho signal, and ignition switch signal (to motronic!). I had connected ign.sw. signal, car is now running with motronic in engine bay. Wire-ing is almost done. ---- '''Mechanical part''' * WBO2 has to be installed to exhaust. (Maybe at saturday) * EGT has to be installed to exhaust. (Maybe later) * Split pressure hose to map. I have every parts needed now. ---- '''Electrical part''' * Need to split VR signal -maybe with a series cond to catch from motronic's in-port directly? * Maybe motronic will be offended at disconnected sensor and inj. cables. We may need to simulate something? (I don't care about "check engine lights" or something, but it must work for ignition, idle air, etc.) ---- '''Software'''' Don't know much about it. * One for sure: need to know 60-2 wheel's trigger position relative to TDC. Don't know it yet.
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.
