The white trace is the primary fuel injector. It’s blipping off randomly. What would the cause of this be? To me this doesn’t seem safe.
Adaptronic 440 select ECU running Eugene.

 

 

Post the ALG file mate, can't tell anything from those screenshots.

 

Not sure what an ALG file is. I converted it to CSV via the program. Maybe this would help?

Hey mate, the ALG is the file you were looking at in the photos above. It contains every piece of data that's been logged plus the ECU configuration. I'll try and have a look at your CSV later tonight.

 

I think you may have attached the wrong file? Different filename and I can't see the behaviour you're describing. Post that ALG file from your screenshots.

 

ECU file attached. ALG attached.

 

Thanks for your help. Much appreciated.

 

Hey mate, no ALG attached above, only the ECU file, and it's the wrong one. Please post up 2020-03-21_1223PM.alg as per your screenshots.

 

It doesn't allow me to post the ALG. Not an accepted file type. How do I send this?

 

Right click > send to > compressed (zipped) folder > attach zip file.

 

LOL. I Have not sent a compressed file in like 20 years! Both files show the same issue. The primary and secondary data log shows what looks like they are turning off.

thanks for the patience.

No worries mate all good.

I had a look and I can't see any reason injector pulse width would be dropping like that. When you playback the log file in Eugene, injector voltage is dropping to zero.

What's strange is that I can't see it having any affect on your AFR trace. Can you feel it happening? The car should be running like absolute dog **** but from what I can see it doesn't seem to be causing a stumble?

If I export the log to a CSV and open in MegalogViewer, the INJ1 trace is smooth and doesn't have any of those dropouts. Can you see it happening in a live log gauge while having a friend drive the car or does it only show up in the logs?

Cheers,
Sam

 

Sam,
No you cannot feel it at all. I just received word form Adaptronic that its a fault with the Datalogger. Nothing to worry about as they found the same as you. The CSV file doesn't show it. Just the datalogger playback and visual representation.

Thanks for your help in taking a look.
Ian

 

Nice, glad it's sorted. I have never liked their log viewer, I use MegaLogViewer HD.
