Timing adjustment on distributorless 4.0 L ranger?
 

This may be a stupid question but I honestly don't know. LOL Anyway my friend has a 90 Ranger with a 4.0 L and he wants to adjust his timing and I couldn't tell him so help me out guys. Thanks a bunch

If it's a DIS I don't beleive you can adjust the timing manually, you'd have to get a chip. Not 100% though.

I believe that you require a chip to adjust the timing, as Godslayer mentioned.

Appreciate the help guys. I'll tell him and see what he thinks, he might want to get the chip. We'll see

Thanks Again, James
