Any feedback about the FAST dual sensor wide band guage? Anybody using one or have direct knowledge about how well they work etc? Close to $700 for the dual sensor set up ... is it worth it?

Thanks, Jim

 

If it's from FAST it's probably gonna work pretty well.....FAST makes some pretty good products

 

Wondering how/where people mount the readout box. It's pretty bulky... but it sure looks like a good tool.

 

I haven't looked at the product yet but most have an output from the control box to hook up a regular WB gauge......you can hide the readout box under the dash and just mount the gauge in the A-pillar

 

Yes, most wb's have a guage that can be mounted like any other guage... I have a dynojet Commander wb now but it appears to be not nearly the quality tool that the FAST unit is.

The FAST unit is a dual sensor wb that reads both banks. It does not use a regular round guage it uses a small screen from which various readings can be taken.

No one here using one?

 

Just shootin off the hip here, but it is an awesome idea! Both banks, but to tune properly and accurately for it you'll need tons of patience or a tuning software that could tune (fuel) both banks. I see the pluses for this obviously, but until HPT(or EFILive) incorporates some way to take advantage of such info, it seems as a high priced guage to me. Don't get me wrong, I'd love to know the afr of each bank at the same time. As far as averaging them together, I'd imagine one sensor in the exhaust stream of both banks at once would be a similar reading in comparison.

BUUUUUUT, what does make the package very tempting is the narrow band simulator function. Replace your NBO2's and wa-la! Not just one. ANd then if you want to tune, turn the averaging on (as long as it had a 5volt output for HPT to read the average) and you are good to go on tuning. Then you can monitor each bank for specific conditions.

See, it's hard to be me...disagree one minute in my head, agree the next...like, don't like, like, don't argrhrgrhgh. LOL

 

So, would there be any advantage of reading both banks if there is no tuning support to tune it out equally? I know the advantage would be just knowing the differences between both sides, but what can be done about it?

Once you start tuning with a WB, a lot of people turn off O2's alltogether. There is a danger of not noticing one bank going bad. So you either tune off WB and use NB to monitor, or you need a dual channel WB to both tune and monitor ignoring O2s alltogether.
Also if you know that one of the banks runs better, you can try to bring it up to the same level so you dont have to compromise to the leanest bank. Or you can do tricks like trying to match the higher flowing injectors to the bank that flows leaner.

 

It seems like the primary advantage would be discovering that one bank is significantly richer/leaner than the other so you know more specificly where the problem is. But... I thought that the tuning programs would allow for changing fueling to the individual banks and since they don't I'm much less excited about the FAST dual sensor wb. I guess I should maybe concentrate on getting my Dynojet Commander to work properly. It's still stuck on 15.5 all the time, ignition turned on or off... ALL the time! In other words it doesn't work and I don't know why. I'll have to get help with that problem and I know a guy that can help with that.

Having checked the plugs I now know my right bank is much richer than the left but I still don't know what to do about it.

I did discover that the intake bolts on the right side were only finger tight (thank you Zippy & helper!). Maybe that caused some of the problem?

 

If you have HPT you can just log your narrow band O2s to monitor each bank individually. This will also help you determine whether or not the O2s are functioning properly.
