LC-1

Post by zmyzgo »

OK, I am ready to insatall the LC-1 in a permenant fashiopn in my Z32...I know where the sensor is going (low point on my split DP's...later to the fron to f my test pipes, asking Greg about any signicant changes in placement and accuracy?

Do any of you have a favorite map to how you ran the wires...any watch out fors, or this route is easiest...
thanks
Hal

follow the LC-1 guide in terms of placement. not too close to the turbo - try and keep it towards the cat converter otherwise it will be affected by air turbulence

make sure it points above the 3-9'oclock mark also.

Not sure on Z32 placement but I've got mine going straight up LHS of the engine and into the passenger area

yup

was thinking along those lines....however unless I have a bung placed in my test pipe, my split downpipes have an O2 bung just before teh test pipes....will that be too close? Alss like their A/F gauge/display and turbo timer.

I thought most widebands (including LC-1) use VW, etc Bosch wideband o2 sensor (LSU-4) that was designed to be used in stock o2 sensor location on a VW, etc???

Bosch LSU-4 wideband o2 sensor -

OK, you like physics more than I...all I know is the LC-1 has a good rep..I know that placement in the exhaust stream could be influential...Specialty Z, has their bung on the test pipe and I just received a response that they prefer the test pipe...probably ok if at the end of the downpipe...
don't want to damage or get bad readings before I change exhaust and other things...just rying to ge the NIStune down, so when upgrade I will be able to quickly get her tuned and the last engine built.

From what I understand, putting wideband o2 sensor down exhaust more, is like what Matt said and the other benefit is o2 sensor last's longer.

I agree

I just want to get this first tune done, so I am not so pig rich....then I will start the purchasing of all required parts and upgrade...move the O2 to the test pipe....would like 500-550 hp, more with race fuel, but stock fuel or mix would be steady/fun/and long lasting....

Im placing mine in the testpipe - a few inches after the end of the downpipe. It is fine to put the sensor in your downpipe if it is only for a first tune. Just make sure not to keep it there to long or you'll be buying a new sensor in no time. I was going to do that but I figured I might as well get it all done at once then have to get a bung welded in at a later date.
