I want to be sure with primary trigger config.

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) ? Best regards, Dave '''A''': Hello Dave, And thanks for you reply! You understand correctly that fw upgrade went wrong in 2011 (and whole car project was left behind to wait better days, which are now I hope). After that upgrade I haven't had any connection to my ECU from laptop. I don't know, did upgrade go to state where 1.1.94 is in AtMega chip already, or is 1.1.84 still there or is there just some corrupted data. You are right, clean start is something that I'm now after. I don't specially need any of those old firmwares. Just newest fw in, car running and hard tune with vt ;). But how to revive from state where ECU is now? And what I have done wrong, any ideas? Did the whole bootloader upgraded in 2011 from nhex to uhex?
