Extra gauges for a turbodiesel

[Eddles]

* I feel all this electric pump, or turbo timers are all a little over the top just to avoid 10 seconds of waiting to turn off the engine for me, considering the age of the car.

* Not going to get an EGT gauge. It is nice and might be useful, but I can't justify the $80 minimum cost. I've decided on a boost, oil pressure and voltmeter gauges.

* Dremd - I can't find a boost only gauge *anywhere*, and I'm sure if I do find one, it'd be quite expensive. I don't mind having to live with the vac part that will be unused.

Thanks to everyone for all your help, much appreciated!

I read on the Peugeot forum that the turbine in a turbodiesel has some kind of boost sensor (this was a thread about someone's turbo malfunctioning). Can the data from this sensor be utilized, or is it some low level, ECU-only stuff?

[Eddles]

Yes, I just spotted that in my Haynes manual this morning. However, I don't know whether I can tap directly into the sensor or it is using a specific method of communicating the data to the ECU. Not sure how I would be able to find this out.

That's actually the set my tdi came with. If you keep your eyes peeled you may find a used egt gauge . . .

The cheapest I can find that gauge in the UK is $85 and Amazon.com refuses to send it to the UK for some strange reason.

I was just coming to the same conclusion myself.
PM sent.

I was looking at this a while back...

Aircraft stuff looks like it might work... ConAir Sports Ltd

Not bought one myself though (yet).

[Eddles]

Thanks!

Already got one thanks to dremd - was mighty kind of him to send it to me. Unfortunately not installed it yet! Hopefully next week as I got a week off work.

Hi,

Just a thought have you considered a TUnit or something similar ? - I think they match an eco4 engine (CR Diesel ?).

They are normally associated with more power but at "min" setting they may give you an economy edge. You may also find a higher power setting results in more economy with different driving techniques especially in the UK with our absence of long, straight highways.

Do you mean this? I've already considered it, £450 seems like an awful lot for possible fuel savings that isn't possible to calculate until it's installed, also my car's 8 years old with 85,000 miles on the clock, I don't think I'll make the money back in fuel savings.

BTW my engine doesn't have common rail injection - just the bog standard direct injection. Opel/Vauxhall didn't use common rail injection on their diesels until 2004, well after everyone else have changed over. However, there is a tunit available for my car anyway.

I'm just being curious but why did you copy my post from a few months back...?
