I was a little pushed for time hence not connecting to the crankshaft sensor for RPM
In hindsight I set the time base a little long and lost detail as a result – but I didn’t know how long it would take the fault to appear
I left the union plugged and took the car on an extended test drive, the fault did not re-occur, finally I had sussed it!
Bringing the duty cycle within tolerance for the ECU.
As I said, it was quicker to connnect to APP.
Sample rate was 1MS/s. As already stated I couldv'e set the scope up better. Isn't hindsight wonderful.
There was no specific PID re. duty cycle. This statement was my own take on the situation
This being a case study I would have thought it open and shut, I went about the job in the method above, I have already stated things could've been done differently and that my initial pump diagnosis was incorrect. I didn't take the time to write it to invite people to question my method - or to help me decide how to spend my money.
and will gladly get a CKP trace if you are in need of one
Your comments tend to be short in the first instance and can easily be read as a bit of a virtual slap down for doing something in a manner you wouldn't have used yourself.
Can you elaborate a bit more on that ?
