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:

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.

Hello Rico,

To assist you in your startup/trigger debug, i would need the following:

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,

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.

Hello Rico,

Lets take it one step at a time, with the corrected config do you have:

If so adjust tdc_delay so commanded timing advance lines up with your timing mark. Its recommended to force a fixed advance via:

Ignition base (verify with strobelight)


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 ?

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
