Racepak O2 sensor

Glenn Briglio · 05-12-2018, 11:03 AM

Racepak O2 sensor: Is there a replacement for the O2 sensor that comes with a clip to hold the two connectors together. Other than going back to Racepak.Actually just need the clip which I broke.

I ran into the same problem, old stand by zip ties was the cure.

Usually the brand, and a number on the Old one. I found NAPA Auto Parts, if you find an experienced parts guy, can take that info and find you the same exact sensor. Not likely Racepak changed the connector on the sensor.

Back when I swapped my FAST stand alone O2 setup for a Racepak unit, i'm pretty sure both used the same connectors, although I don't remember plugging each in to see.

Here's the O2 sensor...

Also, all Wideband sensors don't read the same. Learned that on my dyno. I bought a new one, and found it showed leaner air/fuel numbers than the old one. I ordered yet another, put my pickup on the dyno, and made 2 pulls, plugged in the new one, A/F went from 13.0-1 to 13.25-1. Put the old sensor back in, 13.0-1. Ordered yet another new sensor. Back to 13.0-1. Tagged the Lean sensor at ".25 Lean", and kept it for a spare. If I had a car in that was not as rich as I expected, I put the spare in to verify the sensor I was using was not indicating a false lean condition. Leaded fuel does degrade O2 sensors. I always keep a known good spare for my FAST system on my race car. If you buy a spare, I would back-to-back test them to verify they agree. That is why you cannot just tell a guy to tune his car for a given magic number A/F ratio. His sensor may not read just like yours. That's why we test, right? Mine does not make the best power at the same air/fuel ratio with all fuels, either.
Always something, right?

Ed I like how you say "if you can find an experienced parts guy" that in itself is hard to do these days!

It is. Too many kids doing it now, that think they have it all figured out.
Look for some gray hair. LOL

Ed,
The part where all fuels don't make the best power at the same A/F ratio is missed by a lot of tuners. Same as the guys that tune with EGT #'s.
I had to shake my head a few times when a customer told me it had to have a certain deg EGT's. If it didn't it wouldn't make power till it did.
