Instead of drilling and welding in a bung for an O2 sensor prior to the muffler,(clients car) how accurate would a tailpipe extension tube with an O2 sensor be?
Im thinking of a 1 foot long tailpipe extension with the O2 sensor welded in as close to the muffler as possible, yet without touching the stock system. I intend to clamp the pipe in place with a stainless sleeve clamp so its air tight. Any thoughts? Rich |

Thanx Tim...I am really concerned about part load and WOT....I feel its still to lean based upon the plugs.
So, this is a drive and tune session with the LM1, allen wrench for the MPS (its custom) a POT for the CHT circuit and lots of chinese firedrills till I get the part load and WOT perfect...should be fun...not. I actually may have a chance to buy a floor dyno that is being retired from a state inspection station... I am hoping to get that with the computer and just acquire some simple dyno software instead of the inspection software... That will make it a bit easier to deal with. He may sell me the sniffer, but he may keep it...its up in the air and depends upon the state regs. Rich |
