Busy with a project here that is currently running 12 Cyl Full Sequential Fuel
and Wasted Spark.
Having a heck of a time trying to chase down a Fueling Issue.
In the injector / Coil disabling feature it unfortunately only goes up to 10 Cyl's, Would really like to get Cyl's 11 & 12 available as well.
As access to the Plugs & Connectors on this setup ARE BY NO MEANS easy to reach.
Have to dismantle the top of the engine (ie Intake manifold etc.) to gain access.
So just unplugging on the fly is no-go. (Short of cutting the Cables - I Don't think so.
As I can test all of them up to the last 2 cylinders.
Strangest thing is while running One bank (W12 Phaeton type engine) Runs where I want it the other bank SUPER rich (Monitoring on 2 Lambdas - 1 per bank)
When disabling all of what should be Cyl 7-10 (11 & 12 not available to test) the AFR jumps from high 19's (due to no fuel) to high 14 low 15 with enabling of only 1 injector at a time. Not sure if the Last 2 (11 &/or 12) may be open??
as a side note. When the engine was still open I did an individual Output Test on Spark and Coils to check correct cylinder and sequence, all tested Good..
All Pulsewidths are identical on the TS Gauges (Cyl 1 - 12)
When dealing with 12 cylinder Bentley. it's no joke wondering which is which.
Thanks in Advance to any and all!!
Kindest Regards
Gordon.
