Summary of change:
Chevy 37 (1937 replica), 8 cyl v3 ECU (v3/6717) for SD-logging 8 EGT (not controlling fuel or spark) * was working well for several years (appr.3 years?) ** what firmware was used ? 1.2.11 (perhaps upgrading to 1.2.31 now) * moved to a new engine , new harness, exact actions unknown * worked for a few hours after the move, than VT cannot connect '''SOLVED''' Not sure what happened exactly (several attempts to connect with multiple notebooks) => GenBoard/Firmware/BootLoaderLoopback was needed , "boot mode detected" => '''comm works in both direction'''. Config is saved in vemscfg file, so should be easy to get it logging from there. SD-card erase will be needed after new firmware version is uploaded. ---- '''GND:''' * EC36/5, 21,22,26,32 * EC18/17 is that used ? Inside ECU connected to EC36/26 GND ? ( verify with DVM) See GenBoard/Manual/CommHardware '''PLEASE verify''' * EC18/14 DSUB9/pin3 0V (of course, input) * EC18/15 DSUB9/pin2 -6.4V (seems good) * EC36/26 DSUB8/pin5 GND USB-RS232 adapter (grey), '''Prolific serial''' Model "O232P9". Currently COM24 (verified working with RTN performance logger module) * VemsTune ECU communication enabled (correct COM port selected, theoretically) ---- VT version 2015-09-08 (1.5.33) ----
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.
