550cc injectors on a V6... 5.1 required fuel glitchy

what your saying is that my 55# injectors on my 1.8t is gonna do this but even worse? say it aint so!!! I wish I could use MS2 but it doesnt have provisions for a wheel decoder.

If your 1.8 is a four cylinder you should be pretty good. That gives you about .45L per cylinder where our 2.5L V6's have 4.167L per cyilinder that requires a lower RF value. However if you have the tiny Mazda 1.8L V6 then your really stuck. You could run two sets of smaller injectors and stage them with MSI.

the more I thought about that the more sense it made. Having smaller displacement PER CYLINDER will cause this not smaller total displacement. I thought I was really screwed, but guess thats not the case.

I would really like to see your setup as I will be installing the 550's and cams soon... if this is straighten out. Much appreciated.

Unfortunately, I don't think this will ever be "straightened out" due to the limitations of the MS-1 processor speed.

But to go with 550's I'd deal with a richer than normal idle if necessary (winter starting could be a problem though).
