Walbro 255 remap needed?
My car has the standard fuel pump on it at 120,000 miles I'm thinking I might swap in the walbro 255 I have sitting in my garage just to be safe.
If I do this will I need to get my map adjusted? Car is a 1.8 turbo with megasquirt and 550cc injectors. |
possibly. the base pressure on your fuel rail will increase so you may just need to lower your req_fuel ever so slightly.

Ok I'll see if I can get hold of my mapper and ask him.

If you can run a proper regulator and set it for the stock base pressure you wont need a re-tune at all. I wouldnt run the wally 255 on the stock regulator. Too many people complain of fluctuating fuel pressure at idle.
