Looking to get started on what to read before starting to tune on 7747
Hi all,
I've done a pile of mods on my old 1990 Silverado with a 7747. I've done some minor bin mods including an egr delete and the lean hiway mode mod. I have over 300,000 km on my truck and for the most part my stock programming has been satisfactory. I'm wondering where the best place is to start for tuning my bin to my truck's mods. I've done a pile of data logging with winaldl and I've been using the data collected to work backwards to figure out what the truck is doing and why. I want to start ultra conservatively on the tuning just because of the age of the truck. The only internals I've done are valve seals.
My web site for my truck is http://silverado30mpg.zzl.org if any one is interested in how I'm getting 8.9L/100km on a 23 year old Silverado.
If anyone has additional ideas I'd love to hear...
