racegas + wideband?
i have 110 octane leaded fuel easily available at a pump here where i go to school for 3.75 a gallon. i have a plx m300 wideband with the bosch sensor, and i'm wondering how much racegas i ran run through it before it will start to hurt it?
i have only run about a half-tank of straight 110/premix through so far, but i'm going to start buying more of this fuel because its only like $1.20 more than 93 octane, so why not... i'm jsut worried about the 02 sensor.
anyone have any input on this?

It took 1/2 tank c16 and 1/2 tank 110 aviation fuel to kill my sensor.
Lc1/xd1 and bosch sensor also had about 200 hrs of pump gas on it.

i spoke with innovate tech support and they reccomended useing this if you premix or use race fuels. they said it woud extend the life of the sensor.

Napa isn't the place to start looking for deals on parts.
The PLX uses the Bosch LSU sensor. The Innovative does also if I'm not mistaken. They are OEM application parts in some VWs, Porsches, Audis, Volvos, and, Cadillacs. Use VW part number 021-906-262-B. Cheapest place I've found is www.1stVWParts.com. ~$38 + shipping. They are a direct fit for the PLX.

anyone?

Mine just reads "LEAN" all the time.

sold--no longer in debt
Mine is reading leaner than normal after race gas. It's always around 14:1 all the way through the powerband. I hope that just means the sensor is dying.

it appears that 2 full tanks of straight 110 leaded and a coupe half-tanks has killed my o2 sensor. it reads very slowly and once you get into boost and there is more fuel in the exhaust it sticks right at 13.15:1AFR and doesnt budge until i get back into vacuum and it leans out.

I have an Bosch L1H1 sensor(Tech Edge 1.5). AFAIK this is the same sensor used by motec, and other high end widebands, my sensor has several hundred gallons of 110 on it, and works perfectly. The car runs 10.5:1 at WOT at 20 psi, and idles at ~13:1. It does not like leaner idle than that. I was thinking of putting an LC1 in the car, but if the sensors are only good for a couple hundred miles, it may be a better deal to stick with the high end sensor at four times the price.... Carl

"typical" sign of a 02 sensor going bad is when the repsonse time is alot slower
