Which 3rd guage?

[andyleaves]

Ok here goes...
I have currently the following
PROSport Smoke lens Boost guage
PROSport Smoke Lens Oil Temp guage
Gonna mount these in a 3 pod pillar.
My question is this...
What should/could be the most useful 3rd guage?

Thinking AFR, but not sure
What would you have?

1st Choice.... Oil Pressure
2nd Choice ...AFR..

[Ralliart1]

As Glenn said,oil pressure

[Turbo_Steve]

Oil pressure.
No point in having AFR unless it is a Wideband.

Pedantic ****

No point having an Oil Pressure gauge unless you also fit an Oil pressure Sensor :monkey:

[andyleaves]

So then...
If AFR then wideband needed
else Oil Pressure Sensor needed???
This one any good to go with the other two? (http://cgi.ebay.co.uk/PROSPORT-SMOKED-SUPER-WHITE-OIL-PRESSURE-GAUGE-/110542893404?cmd=ViewItem&pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item19bcdeb15c)

To be honest I don't really understnad have of what you guys say... Wideband to me means digital signals amplified in a similar meths to AM frequencies...

Why should I not go for narrowband? What's the difference?

Narrowband AFR ? (http://cgi.ebay.co.uk/PROSPORT-SMOKED-SUPER-WHITE-AIR-FUEL-RATIO-GAUGE-KIT-/110542892922?cmd=ViewItem&pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item19bcdeaf7a)

A narrow will tell u if ur o2 sensors shagged.
A wideband is what u want if ur going down the route of s fuel controller, piggy back or tweaked ecu or standalone. And if ur going down those routes then an oil pressure gauge and sensor would be on the list 1st /yes

Agree with Glenn, despite being a pedantic ****.

I have to point out, however, that the only reason I bothered to make the distinction is that a narrowband AFR is, essentially, a waste of money.

[andyleaves]

Is that just because it would only tell me if the sensor was shot and not give me a true reading?

It's all academic now anyway, just got the prosport super white oil pressure gauge. This is to go with oil temp and boost gauge.
Just need to get a sandwich plate and a three pillar pod for it all now.
Oh yeah and then run all the cable find my elec sources and plumb the whole lot in.

Sorry.. But you may think i'm being a pedant.. But...

I wouldn't say it's a total waste of money..
As if it showed up a failing Lambda sensor.. Then it could save a fortune in Fuel /yes

[Turbo_Steve]

The factory (narrowband) sensor is not calibrated. Essentially, it has two readings - Rich and Lean. That's all the ECU needs to find the midpoint, which it needs for emissions purposes.

So your narrowband AFR gauge is basically showing you that the sensor has changed between rich / lean, but not by how much.

As you only really care about AFRS when on full throttle, the narrowband is going to simply say "Rich".
If it says "Middle" or "Lean" then you've probably already damaged your engine beyond repair.

If you want to buy something REALLY useful, and plan to modify your car a fair bit, buy a knock display - even if it's just a knocklink.

I meant me.

As for spending £30 on an AFR gauge rather than working out your mpg....you pays your money, you takes your choice.
