Summary of change:
MembersPage/YasecElise Cheat from MembersPage/MarcellGal/EngineSwap/AirFeed (idle air section) instead of the usual 1-2, 3-4 (iac_step_seq=0xC9 or 0xD8) the '''stepper windings are connected as 1-4, 2-3''' (64 Ohm each) I concluded that 0-3 and 1-2 must be driven a half period away from each other. So we need either * 0 1 3 2 (0x1E)or * 0 2 3 1 (0x2D) '''History and LESSON''' Unfortunately installer forgot to document this (it would have taken 2 mins when he made the install (when car-back was off), while it took half day to investigate with the car-back on. The car owner apparently doesn't have proper drawings or connect-lists of his engines's, VEMS installers should make sure to leave this info at the owner. * we searched for a similar connector to connect to IAC * made a test-fixture (connector with cable) to connect to iac ** that can be controlled from a spare-VEMS controller (this turned out to be unnecessary, but it was made the same time with the fixture to avoid a short drive back-n-forth) * swapped to the test-fixture and found how it is in fact connected ** controlled from the spare VEMS
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.
