I'm tuning this Solstice with an L77 from a Caprice.
The Solstice swap guys wrote a program for an E67. I've been fixing pretty much everything.
The engine is stone stock, so I've been referring to the 2012 Caprice tune which is from an E38 ecu.
At steady state cruise in 4th or fifth gear between 30-45 mph, the throttle control source bounces between pedal and idle W/O moving the pedal more than a few tenths of a percent. It's dang hard to hold it perfectly still.
Anyway, the desired throttle changes a lot, from 20% down to as low as 8-9%. So it causes the car to herk and jerk.
I'm thinking I need to adjust the Airflow Final Min table?
Maybe this isn't an issue in a 2 ton Caprice, but it's very annoying in the Solstice.
Any ideas appreciated.
Except for this, everything else is great.
