60mm Wideband Air-Fuel Gauges: ProSport-GlowShift-PLXDevices

I recently posted an article on the OSIR pod gauge I was lucky enough to find at my tuning specialist. Now, I need to find out which gauge to put in the pod!

Since the pod has 60mm holes, I need to find the right 60mm (2 3/8″) gauges. The “regular” size being 52mm (2  1/16″).

So my tuning guy tells me the most important gauge to have is the Wideband Air/Fuel Ratio Gauge. I understand the principles of richer-leaner air-fuel ratios but I still found interesting information and I think it’s good for everyone to read. Here it goes.


Lean mixtures improve the fuel economy but also cause sharp rises in the amount of nitrogen oxides (NOX). If the mixture becomes too lean, the engine may fail to ignite, causing misfire and a large increase in unburned hydrocarbon (HC) emissions. Lean mixtures burn hotter and may cause rough idle, hard starting and stalling, and can even damage the catalytic converter, or burn valves in the engine. The risk of spark knock/engine knocking (detonation) is also increased when the engine is under load.


Mixtures that are richer than stoichiometric allow for greater peak engine power when using vapourized liquid fuels, due to the cooling effect of the evaporating fuel. This increases the intake oxygen density, allowing for more fuel to be combusted and more power developed. The ideal mixture in this type of operation depends on the individual engine. For example, engines with forced induction such as turbochargers and superchargers typically require a richer mixture under wide open throttle than naturally aspirated engines. Forced induction engines can be catastrophically damaged by burning too lean for too long. The leaner the air/fuel mixture, the higher the combustion temperature is inside the cylinder. Too high a temperature will destroy an engine – melting the pistons and valves. This can happen if you port the head and/or manifolds or increase boost without compensating by installing larger or more injectors, and/or increasing the fuel pressure to a sufficient level. Conversely, engine performance can be lessened by increasing fuelling without increasing air flow into the engine.

Now apparently the competition amongst wideband gauge manufacturers is focused on reliability of the gauge and the O2 sensor it requires to read the Air/Fuel Ratio. The best O2 sensor out there is apparently the Bosch 4.9 5 wire heated O2 sensor. Unfortunately, there are only 3 manufacturers that offer 60mm air-fuel gauges and these are: ProSport ,PLX Devices and GlowShift. Both ProSport and GlowShift include the Bosh 4.9 O2 sensor. (PLX Devices have the older 4.2 version, so they are out of the game)

The ProSport goes for 209$ and the GlowShift is prices at 199$ (instead of 349$, as they say). Both are low-priced and have so-so reviews on forums. I personally find the Glowshift Gauges look cheap. One forum member made me laugh when I read his comment: “they look like a dancing christmas tree on speed.”


ProSport vs GlowShift Gauges

So I decided to investigate the ProSport gauges and wrote to their consumer service. First, Glenn answered me on a possible discount:


 The only other manufacturee I know of that makes a 60mm wideband is PLX and theirs is $459.00. It is no secret we have the lowest prices around already. All of our widebands use the latest and widest range Bosch O2 4.9 sensor while other are still using the older, slower, narrower 4.2 sensor.  Our 60mm wideband also can warn you and give you peak recall and includes 0-5 volt output signal for data logging.  All that for only $209 is a very good deal at that price.

Then, he answered mo on the mixed reviews I read on their products:

I can speak from experience when I tell you that on average 70% of the negative comments on forums are due to installer error. Then the poster either forgets about the post or is too embarrassed to go back and fix it so it sits forever as an example  “prosport gauges don’t work” when in reality the problem was  simple ground not installed, you get the idea. 

I have seen negative posts from people and when we ask them to explain, so we can help them they have said well “I don’t own one” well how can you post up about products you never touched or used ??  The forums are interesting as anyone can post anything regardless if it is true.

We have the best customer service hands down.  Take this email exchange for example..  Did you ask the same questions to autometer, aem, plx, etc..  If so how did they respond??  If not- then why not??

On the contrary, I have never seen a negative post about our widebands. They work perfect, because we worked directly with bosch from day one and thus they are matched perfectly.

I’m not big into typing, so if you want to discuss anything in more detail give us a call, we will talk to you for hours if needed to answer any questions you may have. It is just too hard to go into any great details in an email.  If you want us to call you just give us your #.

I think Glenn answered me very well. His answers are good and it all looks to make sense. But still, I’m not sure what I’ll be doing. I may try to fit 52mm gauges in the 60mm gauge pod. We’ll see.

I’ll keep you guys posted.

Audi TT Babes

Yes honey, the babes are on the pics! I would much prefer pics of cars only, without anything blocking the view of the car. But what can I do…


Since I search the web for tuning parts everyday, I often stumble on pics with TT babes. So I started to download them thinking it would one day become an article on my blog. So this is it, the babes page. Once you have looked at all the pics, you can focus on the main reason you’re here, the Audi TT.

Consider these pages as a Christmas gift  🙂

Single Wiper Conversion for an Audi TT MK1 (8N)

After looking at the DTM TT, I have been searching the web on single wiper conversions for my TT. I think it looks great and thought it would be a fun to DIY this winter.

Audi TT DTM Mk1 8N


I found 2 ways: A complete DIY solution that costs almost nothing and a complete kit, witch accessories and options. Obviously, the latter is more expensive and costs about 150$+.

DIY Solution

This solution was fond on a VWVortex forum. I took it from there and I’m not the author. It goes like this:

If you do this, its at your own risk and you accept full responsabity for your actions!!

Tools needed: hammer, drill, drill bit that fits a small machine screw, regular screw driver, metric sockets and a hack saw or grinder.

1. Take off wipers.
2. Open hood
3. Take off wiper arms.
4. Remove plastic trim with gasket and disconnect the washer nozzles
5. Remove the three bolts holding the wiper assy down.
6. Disconnect the wiper assy electrical connection.
7. Remove assy.
8. Using a screwdriver, pop off the linkage connecting the passenger side piviot point to linkage arm.
9. Drill a small whole to shorten the linkage pivot point.

10. Trim the arm width enough so it doesn’t hit the assy support bar, about 1/8 of a inch. and put a s bend on it as well, thats where the BFH comes in.11. Check for free movement, the small arm needs to move almost 180 degs with out hiting anything, the small arm movement is the same as the wiper blade, the more that moves, the more your wiper blade will.
12. Insert a machine screw through the whole you drilled, and also install the a nut with a washer and some locktite.
13. Reinstall assy.
14. Reinstall everything else except the drivers side wiper arm.
15. Trim the plastic peice to allow extended movement of the passenger side wiper arm.
16. Make minor adjustments of the wiper arm placment on the windsheild. in the park position, it should rest where it did orgionally.
17. If all goes well, you should have the wiper arm slide accross the full windsheild.
18. You need to go down 1 size wiper blade

Final result

After reading the reviews of guys that tried this solution, I thought it would probably be easier to find a complete “bolt on” kit. It’s apparently not that easy but still doable. Not for me, I decided.

Complete Kit

After searching the web, I found one supplier (Storm Wipers) that has such a kit, for both RHD and LHD TTs. Also, the kits have several options available. The wiper can be parked on the side, up the middle for the “touring car” or “DTM” look or anywhere in the swept area. Fitting time is approximately 1 – 2 hours.

Isn’t that cool? Here’s the kit picture:

The kit includes: New single wiper linkage, single wiper arm, wiper blade, fitting instructions and a blanking grommet.

There are options available, such as : A stainless steel wiper blade cover that fits over the wiper arm (for a clean look), A wash as you wipe jet that puts winshield washer fluid as you wipe, And different bade options.

Smooth Wiper Cover

You can find Storm Wipers on ebay and the kits go for 75 british pounds, plus options.

I contacted Nick Sanders at Storm Wipers and ordered a kit plus 2 options, the smooth wiper cover and an “aero” blade. (I think the regular blade is too big and does not look good).

More news and pics to come when I get and install the kit.

Update: Osir Design Carbon Fiber Mantis

You guys won’t believe this!

2 days ago, I went to my tuning specialist for advice on cooling the engine temperature on track days. As we were talking about different options to monitor the temperature (different gauges) I told him I searched the web for a pod gauge but unfortunately couldn’t find the Osir Pod Gaude I was looking for. “It’s been discontinued for quite some time” I told him “and I guess I’ll have to find another way of mounting my gauges in the dash”…

He then turned around and asked me to follow him. So I did. I followed him in his stock room and waited for him to find what he was looking for. He was going through dusty boxes, looking under blankets, things were falling from the shelves… Anyhow, after a five minute search he went “Ah-ah! Found it!” and handed me a small black Osir box… There it was: A complete Osir Design Carbon Fiber Mantis waiting to be installed!

I couldn’t believe it! I had just posted an article on this blog saying they can’t be found anymore and BAM, 2 days after I had one in my hands. I gave the garage owner the 250$ he wanted without hesitation and left him as a happy camper.

One thing, I may resell it. Not sure yet. I asked an aluminium designer from Germany to custom design a pod for my car. So I may sell the Osir kit. Let’s see.

Pics! (Sorry for the picture quality. Taken with my iPhone in the garage)
