Ignition Retard Fiesta ST200 2017

Post by John_F »

First of all, I'm sorry if this has been covered earlier (or breaks any forum rules that I've missed) but the search function seems to out of order at the moment.
Does anbody have an idea how to fetch ignition retard readings (if possible) for a Fiesta ST200? I can't seem to find it in any of the modules read.

Post your scan and describe the engine type/version.
Ignition timing PIDs are found when logged into the PCM.
Use my example and post your results with screen images.

Thanks for the quick response- I really appreciate it!
I've attached a few pictures (with an overlap in the last two) that I hope will be OK.

The PID you're looking for is the calculated ignition advance in degrees.
SPARKAVD = Spark Advance

FORScan isn't going to change anything in the Spark Advance table, you're going to see the calculation within the PCM map.
That value is dependent on multiple factors ie:
barometric pressure, ambient temperature, coolant temperature, throttle opening, engine load, fuel quality, MAF readings, Air Fuel Ratio, Cam Shaft Advance and the list goes on.
Any changes are with "tuning software" and that can cause multiple problems.

Hm, I'm not so sure about that. The calculated ignition timing doesn't take into account any differences between each cylinder and all cylinders can have separate retardation and that isn't reflected in the general spark advance above. Also, when going outside the expected load area for the stock calibration it's set super safe so I'd like to see (on all individual cylinders if possible) the correction when advancing the timing to more reasonable levels.

Thanks for all input,

The cylinders can have separate retardation and does affect the spark advance table.
They're called knock sensors.

The velocity of each cylinder is a calculation via RPM sensor (quite useful to measure misfires).

Ignition timing and GDI injection is a mapped calculation.

I suppose the purchase of the MPVI from HP-Tuners years back, was a waste of money and time.
