EPROM update 200 90

I finally got the right upgrade -replacement EPROM (chip ) for the 561 computer in my '90 240 wagon.

The correct Volvo part number is 271838-6 on the box ( and just #271838 on invintory sticker) about $68.00 from Trollhattan auto parts.

I'ts not high performance but a definite improvement over the original.

Much better cold starting , smoother acceleration , and more power accelerating up hills.

also better gas milage in mountains /city.

it's so easy to replace that I'm keeping a spare along with an anti static strap and a chip puller in the glove box, and I taught my wife how to change it out in an emergency (takes about ten minuits).

Thanks again to all who helped .

---------Robert
