Does anyone know of a quality a/f Meter? I know Autometer is supposed to be very inaccurate and I'm not a fan of GReddy's quality. I would like to find one that is as accurate as possible.

What is wrong with GReddy's quality?? I love my GReddy A/F meter. It works great and I have never had any problems with it. I don't know about other GReddy products but their gauges are nice if you ask me.

 

It's not the gauge that's inaccurate, it the sensor. The gauge just converts the electical signal from the sensor into the pretty light display you see. It's pretty hard to screw that up, no matter what the brand of gauge.

If you want an accurate a/f gauge, get a wideband. http://fjoinc.com/automotive/products.htm

 

yes you are quite right it is mostly up to the sensor how accurate the readings will be, but the importance of the gauge is the scale on which the ratio is displayed. For example if you have one increment (eg. light as on Autometer) equal to a full point of a/f ratio the gauge is not that accurate. I would probably have to say that Blitz is the best of the a/f gauges, but for the price it is not worth it. See how you like the Greddy like someone already mentioned.

 

Granularity on a standard O2 sensor display is worth nothing. The thing is just not accurate enough outside te 14.2-15.3 range for resolution to matter. A 30 led display is not going to give you any more than a 10 LED display. A standard O2 sensor is really only good for telling you if you're running generaly rich or lean you're not going to be using it for anything more than the most basic tuning.

 

I have been looking into J&S Safeguard's knock guard and A/F meter setup. Anyone have any experience or knowledge about these products? If I can't find a decent a/f meter I probably will be going with GReddy.

My biggest complaint about GReddy is how crappy their B-Pipes are but I hear that the meters are made well.

 

Anyone try one of these?

 

J & S is definitely a quality product. Almost a must have when running FI. As stated above, the wideband O2 sensor is needed for the upmost accuracy. Several sources (mfg of a/f meters) have told me that the stock Honda sensors are actually pretty good.

 

The stock Honda standard sensors are no better or worse than any other standard sensor. If you're just looking for an indicator that something has gone wrong with your fuel system, just get any of the O2 sensor displays that look nice to you. Any of them should be good enough to tell you if something went wrong.

If you want an actual wideband for tuning, the link I posted above has pretty much the cheapest amateur UEGO wideband around. Around $1000.00 with display, or $800 without display, if you have a standalone you can plug it into.

The J&S is very nice. The A/f meter on it is just like all the others. It's the one I use just to watch the pretty lights to make sure nothings gone wrong.

 

J&S Safegaurd is a very good unit for the quality. I would look into one of those if I were you.

This is the one I just bought for about $15. It'll be fun to put together. Mmmmm.

 

how about a cyberdyne

 

Mojo,
Where did you get that and do you have any more info? Thanks!
