    O2 sensor and open loop and Vf

    mine will be at zero on start up, and when it warms up it will bounce around 2v's even when my afr's are lean or rich. tho my stock o2 is only there for the heater wire, my lc-1 is hooked up but the maft pro is not reading analog out's right so i didn't think the ecu would either.

    r154 pic

    a trick i learned from doing 2/3 of these is when putting the clutch fork on, assemble the pin, and put the c-clip on, have the clutch cover and disk seperate from flywheel, move the clutch cover towards the tranny, once the clutch hub is at a close spot yoiu can insert the fork, note the...

    Going maft pro....need some input.

    yeah, i was just playing with my lc-1 today and i clicked the default settings button, and it flipped my lamba to analog 2 "the brown wire" and i had previously set it up with the yellow wire, the sad thing is, i think the yellow wire is set up correctly for the stock n/b so all you have to do...

    HG help

    well it's obvious you haven't searched long enough, (not tring to be mean!) it depends on how much material is removed from the head and the block typicaly if alot of material is removed it's better to get a thicker one to get the compression ratio close to stock, if the deck and...
