Quick Q: I see a lot of you are using Autometer gauges which are apparently quite good. Are there any realistic alternatives for those? My problem is that I'd very much like to have a matching set, so that rules for example VDO out as they don't seem to have any sort of a/f gauge available... same goes for Revotec, which I'd otherwise get (very nice looking unit and the light matches the 944 amber closely)...

Also, if I go with Autometer, any suggestions what specific model would look best in black 944 interior..? How much to pay approx., and what's a good place to get them?

Thanks!! <img border="0" alt="[bigbye]" title="" src="graemlins/xyxwave.gif" />

I'm very pleased with the performance and aesthetics of my VDO boost gauge.

The AutoMeter A/F ratio gauges and lookalikes aren't very accurate, are difficult to read, and I hear that they are no good for tuning purposes. Some say it's better than having nothing at all. I would rather save my pennies for a more precise Lindsey wide-band kit and mount it in a discreet location.

That's a good point... I was thinking that while a narrow-band A/F gauge can't be used for tuning, it could save my *** if something went wrong while I was driving around somewhere.

A local dealer over here has some -1/+1.5 bar VDO boost gauges available, is that the same you have?

Hi Sami,

I went for a boost guage, and a fuel pressure guage as I have an AFPR. I bought my autometer guages from <a href="http://www.kts.de" target="_blank">www.kts.de</a> . try them!

I installed a boost gauge and exhaust temp gauge. The exhaust temp is a much better indicator of lean fuel mixtures and doesn't dither like the air/fuel does.

I've got a new digital AF-ratio gauge that's much more accurate than the LED variety:

Has switchable dual-inputs to work with standard O2 as well as an upcoming wideband unit. Some feedback on it here: <a href="http://forums.gururacing.net/viewtopic.php?t=65" target="_blank">GURU Forums: a/f guage that changes colors</a>

Mike,
Do you know a website in the states that has the Autometer FPR gauge availble to see? Also, where did you find the fittings to attach the line going to the gauge to the end of the fuel rail?

Thanks

I remember reading a post about a company that recalibrates Autometer A/F gauges for WOT that were supposably very good, but I can't find the post.
Does anyone remember that?

I think it's gadgetseller.com that you are thinking of.

Jason_86_951

That's the one.
Thanks

Danno, thanks for the tip but that gauge is a bit over my budget ...

Mike, looks like my order went there! We'll see how long the delivery takes...

I think an air temp gauge on the intercooler exit would be a good one to have, would give more immediate feedback on an overheating engine than measuring oil temperature.

Mike951

Couldn't you use a water temp guage if you want to monitor engine temperature?

Danno

"Couldn't you use a water temp guage if you want to monitor engine temperature?"

That takes too long to register what's going on inside the combustion-chambers RIGHT NOW.

"I think an air temp gauge on the intercooler exit would be a good one to have,"

Yes, but it will only register the turbo's efficiency. You can have a seriously overheating engine, and if you barely apply any load, the turbo will barely compress any air and the resultant intercooler-outlet temps will be the same as ambient air temperatures. You can even increase the intercooler-outlet temps from 25-C to over 130-C in just 1-second by stepping on the throttle and building boost.

MikeS is right on. The only way to get instantaneous data on what's occuring inside the combustion-chambers is exhaust-gas temps.

Sami, the VDO boost gauge that I have sounds similar. It's a "Cockpit International" and has readings in Bar, PSI, and In. Hg. I love the little turbo symbol!
