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
