I want to be sure with primary trigger config. So, when using 100% same '''36-1''' triggering that Ford EDIS use, what are correct settings? * use the 4cyl 36-1 configlet (we make sure it's available nov 12) ** toothwidth=10 degrees ** next trigger tooth: 18 ** reftooth 0,18,0,18 ** EDIS4 = missing tooth is 90 degrees before VR sensor when first cylinder is in TDC. --> Thanks for advice :) ---- ''' Story continues... with old connection problem''' In 2011, after last editing of this page and after a couple on engine start-ups, I tried to update latest firmware (from 1.1.84 to something that was newest in Aug 2011) before I start to tune engine. Something went wrong and now '''I don't have connection to ECU thru COM-9'''. ECU Detect on VemsTune: received ~80+ bytes and send ~5 bytes. So, big guestion is; what to do? ''AVR ISP cable USB'' from VEMS Shop and try Bootloader update? Or am I totally lost with this ECU? Or throw this ECU away and back to basics with original injection :(. After four years, I have got back some tiny pieces of motivation to get this car back to road and track again =). ---- '''Q''': Could you elbaborate on exactly what steps you took to upgrade firmware ? did you use firmware upgrade wizard or non-wizard, what firmware did you try to upgrade to ? This information will provide some insight into what might be going on. Best regards, Dave '''A''': Because I don't maybe remember correctly all the things that I did four years ago, I can't be sure about all details. It's sure that I have connection thru VemsTune and from VT I tried that Firmware upload from 1.1.84 to last released code. I guess it was 1.1.94 and day was maybe 6. Aug 2011? I have to dig out some old files and notes, if theres some additional information. [http://i200.photobucket.com/albums/aa215/koskar1/RS2K/Mk4%20RS2000/VEMS_5.jpg Pic of last working FW on LCD] I have put two indicator LEDs on board, should I see something if ignition power is on? And TX/RX -bootloader jump/shorting is something that I may try? cheeRS, Koskar ----- Hello Koskar, So if i understand correctly the firmware upgrade gone bad was already in 2011 and you are now trying to revive your ecu, which now has 1.1.94 to a previous state working state of 1.1.84 ? Or do you intend to start over with a clean slate and new firmware (1.2.31 recommended in that case) ?
