Visit Preferences to set your user name Summary of change: get error : file "vems.hex" is missing. duplicate from report: http://vems.hu/vemstune/bugreports/reports.php?cmd=view&key=zprqad ----- Hello Rico_pl, Upgrade to firmware higher than 1.2.11 requires bootloader upgrade, please follow the procedures on: http://vems.hu/vt/help/v3/general/bootloader_upgrade.html Best regards, Dave ---- Thanks Dave, as I bought the car with VEMS unit (Escort Cosworth), I have set Trigger to "Lancia_cosworth". My first error report shows I have trigger signals but RPM is 0 while cranking. Acc. to WIKI I should use firmware 1.2.26+. Is this correct ? Or should it work also with 1.2.11 ? I cannot see why RPM stays 0 while cranking. Fuel is injecting. BR, Rico ---- Hello Rico, To assist you in your startup/trigger debug, i would need the following: * a triggerlog of engine cranking 8-10 seconds no IGN or INJ fuses * a vemslog of the same sequence Using these i can get a beter understanding of whats going on. You can upload these files to the FileArea and link here or fire a sharing report (from VT) and link that. We'll work from there. Best regards, Dave ----- Hi Dave, here the link http://vems.hu/vemstune/sharingcenter/reports.php?cmd=view&key=pmPtyJ BR Rico ---- Hello Rico, I have reviewed your triggerlog and vemslog, this trigger type should work with special trigger type = Normal, Tdc after the trigger is likely to be around 60deg, use a timing light to verify and adjust. I have attached a corrected config (having these suggested changes) to your sharing report. Best regards, Dave ----- Thanks I will test this. But why is RPM =0 ? I thought it triggers on TDC so 0 degree ? BR, Rico ----- Hello Rico, When using simple trigger with camsync, rpm will show 0 when cam sync is not accepted (or not seen), so without sync it will not show rpm. With the corrected settings that should hopefully be solved. Best regards, Dave ---- Thanks Dave, but I do not understand the 60 degree value. If I set TDC both teeth (prim, sec) are on the sensors,so 0 degree. Sorry for all questions, you can give me your Paypal and I can make a donation. BR Rico ---- Hello Rico, Lets take it one step at a time, with the corrected config do you have: * good rpm and sync ? * spark on all cylinders ? If so adjust tdc_delay so commanded timing advance lines up with your timing mark. Its recommended to force a fixed advance via: * VT->Starting/Idle->Priming, Cranking, Afterstart Setup->Cranking Ignition Advance (cranking only, initial setup). * later check (again) via VT->Tools->Ignition lock (when engine running) '''Ignition base (verify with strobelight)''' * small adjustments can be done with tdc_delay (1/2 crankdegree steps) * bigger (eg. 6 .. 30 crankdegree depending on wheel) steps: it is recommended to '''choose the first trigger tooth so that tdc_delay is in the range of 60-100deg.''' * finally the spark advance (tuning) in 1/4 crankdegree steps ---- Hi Dave, I uploaded latest log in sharing report. RPM is now ok. In Test Mode a spark is there. How is the First Trigger Tooth defined ? * '''tooth0 is the tooth after the missing tooth.''' ** eg. TDC after the trigger = 66 deg + First Trigger Tooth=6 (*6 deg for 60-2 wheel) means TDC is 66+36=102 deg after tooth0 Thanks, but I have no missing tooth. Ford has only 4 teeth wheel.(+ 1 tooth dizzy/distributor) I use COP kit so using strobe is difficult. I will try. BR Rico Hi Dave, no luck it won't start.What would be the FTT on my setup ? If I modify the sectrig (30 degree before TDC) would that help ? Thanks, Rico ---- Hello Rico, Verify ignition timing '''with timing light''' and adjust tdc_delay , first triggfer tooth where needed, make sure firing order is correct on your ignition outputs. On COPS you can use a small piece of old ignition lead between COP and sparkplug and put the timing light there If you have rpm and sparks, getting the engine to fire should just be close. Best regards, Dave ---------------- Hi Dave, checked timing but still not starting. It seems when I plug all ignition and injectors that on cranking the injectors get no signal or the plugs. In Test mode the injectors work. I tried with 2 batteries but still no spark. Before I removed all plugs and they were sparking. (but injectors were unplugged) Thanks, Rico ---- Hi Dave, finally found the issue. It seems the FPR was locked so inside the tank a hose was ripped. So fuel pump was working but no fuel to the engine. It starts now but it wants to set Lambda 1.0 with a cold engine so it dies after few seconds. How to prevent this ? Thanks, Rico ---- Hello Rico, The likeliest cause of engine dying after startup is either required fuel too low (see base setup->engine setup->required fuel in VT help: http://vems.hu/vt/help/v3/v3_engine_setup.html) or afterstart/warmup enrichment need adjusting (see starting/idle warmup enrichment/afterstart enrichment curve). The closed loop targets for ego control are set in the Lambda target table. Best regards, Dave Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
