Visit Preferences to set your user name Summary of change: Under this Post I will post a list of Units that will be sent in for repairs. Please do complete functionality test on all units. NEW 2018-01-25 ---- I have 11 units in need of repair or return. Unit nr 1: Serial nr 6858. Multiple high current damage, Caused by burnt coil - damage mainboard No comm. Mainbord replacement. VR/Hall 2+6Logic. Unit nr 2: ---- OLD: ---- Send detailed individual cost of each repair to Info at engdahlmotorsport.se Ask for return address before sending back, I will change adress 2016-08-30. Please send out the units 2-3 at a time. As soon as they are ready. ---- '''RS232 serial communications''' Please note that '''devices with dual WBO2 (and old devices) have NFET on EC18/pin17 (2nd WBO2 heater), not GND as most new devices'''. * That means RS232 connection with GND only on EC18/17 (RS232 GND not connected to EC36/26) will fail to communicate, or worse: sometimes communicate, but unreliably. (eg. communicate with engine off, but frequent comm disconnects with engine running). ---- Unit number: 4130 belongs to Engdahl/RBD Damaged LM1815. Unknown reason. Also some unsure funktion of some parts. Test everything. Please change it, or change is to Hall if not possible without board replacement. ---- Unit number 11658. Belongs to Engdahl Brand new unit. Burnt Stepper chip due to short in solenoid. No communication after the chip fried. Main board replacement authorized. ---- Unit Number: 8168. Belings to Engdahl Injector channel/channels grounds on powerup. Suspected INJ driver chip damage? Test it and fix whatever is broken. Main board replacement authorized. ---- Unit Number: 2365.

Efter firmware update it died. No comms. Main board replacement authorized. ---- Unit Number: 1959 belongs to Engdahl/RBD * No communication. ** seems to communicate without problem (no CRC error). '''Check the bench RS232 cable connection, especially RS232 GND to EC36/26 connectivity''' ** doing bootloader upgrade and more tests Main board replacement authorized. ---- Unit Number: 533 belongs to Engdahl Really old, lost of problems.
