Answer to original question; Yes. Gauge is just a voltmeter. Tulka

one advantage of using the wideband Innovate LM-1 unit is that Innovate has a great forum that anyone can use to ask tuning questions, whether or not they own an LM-1. There are some very knowledgeable people using the forum and the information they provide is pretty impressive. The LM-1 unit is pricey, but it is a very well-tested and respected item. You may find that if you use a chassis dyno with a good wideband sensor, they can give you the A/F information and tune the carb using the data. Once you get it setup on the dyno, you may not really need an A/F meter installed in the car. I have seen very few A/F meters installed with racing A-series setups.

If I end up going wideband, and from the comments here that seems to be the way to go, I was considering the Zeitronix Zt-2, which does have datalogging capabilities. 1981 Mini, 998cc , Stage 1

I guess I'm old fashioned and hardheaded! I'll stick with seat of the pants tuning.

wideband is the only way to go.

I sthis the one being referred to: http://www.jegs.com/i/AEM/017/30-4100/10002/-1  Is that all that is needed? There is no controller for the gauge? It appears a controller is needed for data logging. Link to: http://www.zeitronix.com/Products/zt2/zt2.htm from below

Same comments. I have a narrow band in MOKE, but find it not any better than I can do with setting by ear and plug cut reading. It's not too bad for steady speed readings once warmed up, but it's too slow to respond under on/off throttle conditions. The dyno I use has a good wide band reader and it works fine with SU set ups. I've done the reading on wide bands, too, and can't come to a decision. Soon, though!

The K&N one is not a wideband...hence the cheaper price. I have been looking into this as well, and the AEM wideband seems to be a good economical choice (around $200-$250 I think). A wideband setup, and a dyno session would be a good way to go.  Cheers, Andy No other car makes everyone smile like a Mini does! www.toyboxracing.com

I have one of these plugged into my V8 Morgan attached to a K and N gauge. I found that with carbs it is very difficult to get a steady reading, it will tell you if you are rich or lean, but typically if you have some experience you can tell this buy driving. Next time I have the header off the Mini I am going to weld a bung into it to see how it operates with SU's. I did not find it all that precise.

You can get a MPI exhaust manifold, it already has the hole for a sensor. From what I have read the manifold is pretty good for up to a mild 1275 in the 80hp area. "How can anything bigger be mini?"

buy a VEMS wideband gauge, or an AEM one. They will give you the needed info. both are wideband -André-

I agree, a dyno session is the best option, but the only one around here does not have the capability to monitor exhaust gas. I have spent money on several sessions there and have gotten disappointing results, as it is truly trial and error, mostly error. I am looking for a better and cheaper way. I envy the folks in the U.K. who seem to have no problem finding a rolling road with an experienced operator who knows A-series engines and can produce a custom needle if needed. Nothing like that is available in SW PA! 1981 Mini, 998cc , Stage 1

Its a great way to understand how the engine is responding to changes you make. I highly recommend it, but a dyno would be a better way to do it if you have access to one and have a selection of needles on hand. The guage will allow you to narrow it down.

Just curious - has anyone ever installed an O2 sensor in the exhaust and used an AFR meter to monitor fuel mixture under driving conditions? I am aware of the limitations of narrowband vs wideband sensors, but I am wondering if there is a cheap way to evaluate needles and mixture settings under load conditions that might at least be better than the "butt dyno" method. Any thoughts? Thanks! 1981 Mini, 998cc , Stage 1
