I currently have a MAFia and a stock MAF with a draw-through configuration.
I'm moving to a 3" housing and blow-through with no MAFia.
I know this will end up being a drastic change in the MAF Transfer table, which I can handle.
What I'd like is a suggestion on a starter tune for adjusting to the 3".
My thought was to reload the MTF and manifold volume back to stock, and then add 10% fuel to the MTF just to get started and see how it runs.
Perhaps load a 5%, 10% and 15% richer MTF tables into the xcal to save some time.
So my questions:
1) What can you all suggest as a starter MTF for the 3" housing?
2) What oddities should I expect to run into? (aside from leaner AFR due to lack of metering of the extra air)
3) Will any idle functions need adjusted?
All tips I'm looking for are regarding N/A tune.
However, if anyone has a suggestions for boost and 3" MAF tube I'll welcome those too.
My plan is to run with the wastegate open until the base tune is where I want it.
By then I should have enough data to make educated adjustments to the upper portion of the MTF table and start running boost again.
I should also mention my car is already tuned for 9.5psi boost with the draw-through setup.
Thanks all. [wrenchin]
