I found this on pgmfi.org..... it is the best "starting point" basemap I have used..

I use the IAB's in my h22..... so p30 wasn't an option, and I don't really like the gold rom...

if anybody has ever tried to auto tune with the p72 rom in crome pro... you'll notice the red cells in the target lambda area..., they all read o.oo and throw the auto tune off something crazy.... problem solved with this rom....

although I only use the auto tune feature as a tool to get me in the ballpark area of a tune.... I have found that is pretty accurate if you get the wideband offset set perfectly..... another thing is the 5 volt ecu mod.. I did this mod, and now my lc-1 guage, and crome pro a/f readings are the exact same.... with an offset of -0.02, but hey, nobodys perfect

anybody want a copy...?
