Howard,

Try settting D0960, D0961, D0962 all to 100% all across.

Thanks Joe.
I get a stutter/bucking which seems to be TCC and heat related.
Any suggestions on how to st up my trany tables?
Currently I have the stock van tune settings in there.

Hey..hate your avatar...but I really like your signature.

Well, tried running my 60E settings and the Burb ran OK.
But...still getting this bucking at around the 2000rpm, low speed area (around 40kph).
No idea! I don't know if it's TCC related or not? deffinately seems to be heat related as it only starts once the truck's warmed up. I don't believe I'm running hot though...trany or motor.

Howard,

My opinion ($0.02): at around 2000 RPM (near the start of the log), 22°-23° timing may be too advanced... and it's also knocking right there too.

I don't think it's related to TCC locking to early... your engine should have plenty of torque at 2000 RPM to be able to pull thru with TCC locked; I wonder if a temperature based modfier table is kicking in...

do experiement: set TCC locking to occur at sigmificantly higher speed (i.e. putting it well above the 2000 RPM region), and see if the same symptoms occur or not.

Cheers,
Joe


I like Mick's other avatar, the scull one.

This is a log I just ran using my 60E settings...still doing it.
I think it's deffinately heat related but this afternoon it wasn't as bad???..And the weather was warmer!
