I have tried command S,s Man but no serial contact Avrdude version: avrdude-5.6cvs.tar http://www.vems.hu/files/MembersPage/PeterJensen/avrdude_1.jpg '''Bootloader ISP upload''' '''To upload main.hex using Avrdude and ISP''' find main.hex in http://www.vems.hu/download/v3/bootloader/ http://www.vems.hu/files/MembersPage/PeterJensen/avidude.jpg ---- ''' I have a problem with contacting megatune''' Vems have been subjected to great hardship as there has '''been a bad ground connection'''. * p259 is usually the first victim (often the LM1815 VR trigger chip supply gets lost), but the fetdriver, mcp3208, i259, the processor or other chips can get damaged. when I turn on Vems can I get connection for about 2 seckunder with megatune and then lose my connection. * just in case, check firmware version (ManmdV and megatune version). after 2 seconds prosessoren bring some of the output high * high or active ? Active means low for injector control pins (because fetdriver is inverting) * which legs ? Is it possible to delete the program in prosessoren and then upload a new firmware ? * yes, just upload a firmware. ** you can verify before uploading new firmware, to see if it changed since you uploaded (this is extremely unlikely though) ** if you cannot upload via megaloader / vems.hu/download/v3gui/ vemstune, and suspect bootloader damage, it is possible to remove endplate and reupload bootloader with ISP, but this is extremely unlikely to be the solution (damaged bootloader is just very unlikely ). ---- '''Dual Stage Injection''' A friend of mine is consider to buy Vems and he has some questions: Can Vems run dual stage on a 5 cyl. S2 engine (10 injectors) If yes can he adjust the petrol/methanol (second stage) like a look up table? He likes to have petrol like normal 5 1025 ml. inj. And petrol mixed with 20% methanol fore the five-second stage injectors and it is necessary to could adjust the mix in rpm and load you can set the flowrate ratio of injectors (first and 2nd stage). You don't need to set 2 VE tables, just one. The 2nd stage is only used at higher pulsewidth (higher load). ---- '''Audi S2 standard TEMPERATURE sensors''' Need to calibrate the mat and coolant. What airXfactor hex and cltfactor hex. See * EasyTherm ** EasyTherm/SensorTable * MembersPage/MarcellGal/PowerAndTraction/TempTables The best for coolant is 1900 256 (shows appr 10C lower, so you get indication well above 102C coolant temp). For air: 425_260 is a good starting point for a PTC, with the 430 Ohm pullup (2700 Ohm x 510 Ohm). Minor note: even if you have an NTC table in the ECU right now, the reading is useful to find out where the ADC is at certain temp to make a good choice: download calibration zip from EasyTherm and use the csv spreadsheets). ---- Question: Is this a good setup fore 60-2 trigger. Peugeot 2,0 Please comment: '''Next trigger tooth must be 30 !''' Also, strobe the engine for exact ign_tdcdelay (1 tooth + 60 degree might not be dead on). http://www.vems.hu/files/MembersPage/PeterJensen/trigger.jpg
