Using wide band to tune cis?
 

Did a search but nothing conclusive. I just purchased this out of curiosities sake to see what my afr is at full throttle.

Gonna try to install it next weekend and see what we see:cool:

Cool, I was always interested in getting the innovate LM-2 wideband with logger... But didn't know how you would trace it vs. RPM. I wonder if you can log multiple channels with it? Oh well I will look into it more when I have the money...

Tom - I have a LC-1 with turbo timer in case you want to try one of those. All I know is I keep blowing out o2 sensors. lol

I wanted to try it as I have a friend with a turbocharged, VW powered Manx buggy. He's running a blow-through carb set up and he swears by the PLX wide band to aid in tuning.

I have been thinking of getting an Innovate kit also. Please let us know how this one works out.

I'm not sure if you would need a logger with CIS if you have a display. It seems like you could only tune for full throttle, or maybe for fuel economy, since there is only one adjustment and it affects the entire range. I could be wrong though, I'm still learning about CIS.

At WOT, my AFRs would be in the 9s.

Yeah, but you're turbocharged. And besides, flames on decel are cool!!!:D

I got this a short while ago MTX-L Wideband O2 Digital Air/fuel Ratio Gauge, very easy install, works a treat.
Just had the car dyno'ed and the AFR results from my Innovate and the dyno machine where almost identical (they had there dyno re-calibrated only a few months ago so its spot on) so it does a good job too.

I'd be curious to see how this works out for tuning CIS as well. For $200, not much to lose!

There is only one adjustment in stock trim but you can have your WUR built to be adjustable and then have a much wider range of adjustability.

I think that'll be the next purchase. Or on of those digital wur(s)........

You would know for sure if you didn't drive like a 90 year old Asian lady.

:mad:

It is in the mid nines. Cruising is 14.7 and when I step on it, it drops rapidly. Unfortunately, the o2 sensor is gone so I haven't tested WOT with the fuel enrichment dropped down a notch.

You aren't even going to attempt to deny this?

Ronnie's930, I'm curious, how does one get a WUR to be adjustable.....is there much involved in doing this? Villiageidiot sorry for hijacking your thread!

Cheers!

I am a DIY person, but for this I just sent mine to the WUR guru, Brian Leask.

Another guy, well know on this board, Brian Bodart - RarlyL8 Motorsports, even stocks already modded WURs that you can buy . . .
