Summary of change:
'''GenBoard/VerThree install on Honda B16A2 engine''' * initially naturally aspirated, but later for turbo version ---- '''Trigger''' There are 3 transmitters with toothcount 1,4,24 in the distributor (with honda PGM-FI ECM pin numbers): I've seen the toothwheel, the 1 and 4 tooth per camrotation are obviously VR. * 1 (B11 ?) Autodata lists 0.2V for cranking, 0.7V at idle and 2.5V at 3000 RPM for B11 * 4 (B13 ?) Autodata lists 0.4V for cranking, 1.5V at idle and 5V at 3000 RPM for B13 * B12 Autodata lists 0V for cranking, idle and 3000 RPM (this must be ground line) * B14 Autodata lists 0V for cranking, idle and 3000 RPM (this must be ground line) As you see, autodata suggests that these are VR signals (amplitude increases with RPM). If above is true (2 VR signals), the assembled ECM auditrigger configuration should be used without the cam-HALL connected. From the Honda service manual *TDC Sensor (1 tooth) VR+ orange/black (b13) VR- white/blue (B14) *CKP (24 tooth) VR+ blue/green (B15) VR- blue yellow (B16) *CYP (4 tooth) VR+ orange (B11) VR- white (B12) Double check polarity because when I measured the pattern, hooked up this way the pattern went down instead of up. [MembersPage/PhatBob] There is no need for the Audi Trigger, as we should be able to use a configuration similar to this: http://www.vems.hu/wiki/index.php?page=MembersPage%2FMichaelRichards%2FProjects%2FNicksGTX%2FTrigger This is almost exactly the same trigger type as the Toyota ones I'm looking at in VehicleFitment/Toyota. With the 24 pin for engine speed and the tdc/sync sensor you should be able to get VEMS running fully sequential injection and even coil on plug! ---- Wants to use (063/064 type) LSU4 WBO2 sensor in the Honda (red street car) exhaust. Since still using a factory ECM (OBD0), "NBO2"-style signal is needed. * will use AfreshTiny continuosly for measurements (appr. 1.5m cable needed between the round display and the WBO2 connector). ** NBO2-like Vout (function) is needed (for the Honda OBD0 ECM) When Afreshtiny round controller is removed (for tuning another car), the engine will normally not run (but it would be nice if it could run without it: eg 3 x diode drop for the heater and adapter connector for use as NBO2 - without the pump).
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.
