anyone still watching this has a truck not yet supported by efi.
Yeah I do
Yeah it'll defuel if I hangon longer and defuel then snuff if I do sooner. Won't try sooner again haha
I'm not saying thats not got potential to be a problem but at the same time if the truck thinks its a manuel then the tranny and motor should act as seperate parts, That being said it shouldnt matter if the tranny goes from 1-2-3 or any other pattern it should keep fueling.
Are there any wires going to the trans from the ECU?.
My point is, if you shift early or later (seemingly randomly too) and it defuels every time on the shift, it may be in fact slipping for a moment. I haven't looked at your videos (yet).
