I'm looking at this one for $350 shipped.

http://www.innovatemotorsports.com/lm1.php

Problem is, I'll likely only need it for a day... After that it's eye candy (I guess in this case, it is cheaper just to go to the dyno).

Anyone have a similar unit handy for "loan." Anyone want to rent mine if I buy this one (lets say at $50 per week). Maybe someone wants to co-own it with me?

I've read a few comments pro and con about this unit, but it's accuracy hasn't been challenged (just the small display and less than great software). I'm running carbs, so all I need to do is get it close... I've shown on the dyno that air-fuel changes don't make me much, if any power, I'll just be tuning gas milage and "safe" A/F readings.

Scott,

You may want to consider this Wideband: http://wbo2.com/ I think the entry fee is around $150-$160. Thats alot easier to swallow if you dont find one to borrow.

There are a few add ons that bump the price up a bit. Im thinking of getting it myself, they seem to be popular in the DSM crowd.

I would get the Innovate, but I'm sort of biased.
I have one sitting at home (not installed yet).

A friend and I each bought one in a group-buy, about $350 shipped with the analog gauge. Plugged his in and it works like a champ. I would recommend getting an analog gauge (but not theirs) if you plan to leave it installed in the chassis. I sure will like having it in there to tell me AFR when I'm pushing more air through my RX-7 when it is resurrected from the dead...it is much easier to read a needle on a dial than a small LCD.

I went the DIY route before. Not worth the pain (especially if you build it yourself). The only advantage to the DIY is that there are schematics if you need to fix it. The prebuilt DIY may be worth looking into. The newer 2B0 unit is VERY promising, but no schematics, so you are about as good as the Innovate in terms of self-maintenance. Make sure that what you are getting doesn't use the NTK/Honda sensor, as they are now hard to find and way more expensive than the $40 or so Bosch.

The interesting thing I read about the Innovate is that it is fully "digital" -- there is a single PIC chip that controls the heater/sensor and because of this, the unit (and more or less the whole wideband algorithm) is software updateable. I'm not sure what they have done with the DIY since ver 1.0 that a friend and I built from scratch (he's an avionics tech with the Air Force, so no problem soldering it up, calibration and making the display work was a PITA even with two smart folks working on it, but at the time, the next cheapest WB02 was like $800, and $250 or so was very appealing, especialy split two ways).

Only problem I know of with the Innovate is <sigh> with rotary engines and the fact that they get a "little" hot and the sensor may go "overtemp" and quit displaying AFR's. There are a few solutions to this and I need to spend some quality time on their forum seeing if anything new is going on. IMHO, better that is display an error than it displaying incorrect AFR's...

Wideband discussion can get to be a can of worms, especially when you get egotistical tuners in the picture. I'll leave it at that.

Just another bump on this one since it might go on my Christmas list. I'm learning that there are many variables even with carb jetting.

At Dyno day Jeff mentioned that he saves a bunch of money not buying DynoJet wide band sensors. I believe he said he gets one that is for an '01 Saturn, but I'd call and confirm. Only $50-75 for the sensor.

I own the TechEdge WB02, that I build myself with my mad soldering skillz. The greatest thing is that it uses the VW sensor that is only $35.

I would be happy to bring it by and work with you if you want help. I have datalogging software for it as well, depending on what you are after. You can shoot me a PM and we can work out the semantics.

There's an article in this issue of GRM about wide vs narrowband sensors for tuning where they compared 4 wideband setups to a narrow band on the same car at the same time.
