True enough, it won´t show detonation instantly. But moderate to severe detonation I can easily hear, and the dangerous slight det. I hope will show up on my EGT meter before getting critical.
Obviously detonation must be avoided in any case. But that danger goes with an AFR meter too i believe. Detonation can occur with correct mixture also, and too high temps can be produced even with the correct mix.
Since I even got a fuel pressure gauge i feel pretty safe.

Stu, funny you should mention failed fuel pressure regulators today, a few days ago my friends liner melted down on the way home from buying it, and the reason it would appear at first glance is that the MAP pipe into the FPR had come off, meaning that the FPR wasnt staying the same differential from the manifold pressure that it should.

10p worth of pipe failure = bill for many thousands (well would be if he wasnt going to rebuild it himself, but even DIY its going to be well into 4 figures)

Alg1k · 23-12-2005, 11:52 AM

I monitor the 4 egts out of each cyl and i have a wide band afr meter i also monitor the fuel pressure which has a warning light which pisses me off when im not on boost
BUT its better to be safe than sorry

No.
Otherwise it would come on whenever you reached this low AFR, thus part throttle, idle, cruise, blah blah...

It needs some intelligence to be useful. EG:

Over 22psi + over 60deg throttle + over 3000rpm + leaner than 12.2 = ENABLE.

Anyhow, anythings possible, was just making the point that it does it out of the box and does it well, so its my preffered unit, i also like all the others.

ah obviously lol

i need to fit my 044 pump .. just need the fitting to do it ...

Rick · 23-12-2005, 12:23 PM

Stu, i said technically, not most accurate - will defo be intersted in tests

The LM1 does have warning lights, and programable outputs to trigger anything when used with the XD1 digital gauge. For data logging, you can either touch a button to start/stop a session on the gauge or the Unit itself.

any chance of a group buy stu??

Mechanic_Wedgie · 23-12-2005, 02:29 PM

So a standard or stage 1 saff has less risk of a melted piston because they don't run an high boost like a stage 3 saff?

For example, take the old fuelpump of Stu's car, with a standard or stage 1 saff there where nothing wrong because the boost isn't high enough so the fuelpump works correct and fuelpressure doesnt drop on boost, or am i totally wrong here?

cheers

Spot on for 3 main reasons:

1 the pump sees less resistance

2 the pump doesnt need to flow as much for 280bhp as 330bhp anyway

3 if you DID get a slight leanout, its safer at lower boost and less likely to melt something

Ian2wdsaffcos · 23-12-2005, 04:00 PM

Good post Stu

Question for you though mate, how old was the std fuel pump on your car? I'm asking as because you know you have my old Saff in with you at the mo & 2 years ago I had a brand new std one fitted as a safety precaution, thought about going for an 044 but heard it wasn't necessary for stg3. Dave (new owner) was on about gettin one fitted & I said the same to him (that that new std one should be fine for many years to come especially with new wiring - unless of course he decides to make use of that ported head I never knew I had on there

with some greys). Is this true or was I talking bollocks again & would you recommend he should really get an 044 fitted?

Cheers,
Ian

YBP · 23-12-2005, 05:55 PM

Don´t mind of course.
It´s an aircraft instrument.
It has four inputs, so you can measure multiple things with it. Watertemp, oiltemp, cylinderhead temp, chargetemp before and after intercooler, EGT, pretty much any sensor you want can be purchased to the meter.

Since it´s approved for use in aircrafts I guess it´s pretty accurate too.
Approx. £100 incl one EGT sensor.

Dave wouldnt want to be doin any hammer time with AFR'S like that in yours pal get it checked out on the road,IMO Should be in the 11's if not all but most of the time,looks a tad close to the bone to me

On my topspeed runs i was 11.6 ish droppin to 11.3 top end at limiter.

the original · 04-01-2006, 01:43 PM

sorry to hijack the thread but i wanted to show my pics of the gauge fitted.
i have 5 egt probes around the engine now- 1 in exhaust housing of turbo and one in each runner of manifold

and ask a couple of questions....
what should i set the alarms at? (currently set at 870degC)
and at what difference between cylinders should i be worried? because i see 100 degrees difference at tickover between 1 and 4....

cheers

Karl · 04-01-2006, 02:18 PM

Depending on your inlet manifold design (i.e. if you have a single throttle plenum) you will get significant differnences in EGT's at idle. This is due to the large difference in AFR's on each cylinder at idle brought about by the each cylinders inlet runner proximity to the throttle body.

As an example on my own car which has a centre feed single throttle plenum I see 300DegC in 1 and 4 headers and 400DegC in headers 2 and 3 at idle.

However this is largey irrelevant as it is your on boost EGT's that are important. Here a correctly designed and mapped engine can see as little as 10DegC between exhaust ports!

With regards to safety limits I personally allow 950DegC in the exhaust ports of the head, and up to 900DegC in the down pipe assuming you are not running with significant exhaust system back pressure. If you are it is possible to see the down pipe temps rise above the head port temps. In this situation you should increase exhaust bore size.

Ideally you should see anything from a 100 - 200DegC drop between head port EGT's and turbo downpipe.

Beach · 04-01-2006, 02:25 PM

Could be worth getting a new 044 before the ring trip

Cheers Stu, very good point with evidence to prove

Rab · 04-01-2006, 02:29 PM

Well, I know all about leaning off on boost. My fuel pump died on boost in 3rd, going up a hill, just a few weeks ago, melting 1 and 2 pistons

Thought it was going well

Was that the guage on its own or did it include any thermocouples? If you bought the thermocouples seperatly which ones have you used, and how much did they cost?

It included no thermocouples
all the thermocouples i have were supplied by ForeigneRS

foreigneRS · 04-01-2006, 03:52 PM

thermocouples came from www.conrad.de

can't find the exact ones on their website, but they're something like Artikel-Nr.: 120757 - 62 but made of inconel

only 1.5mm thick, which is quite fragile, but fast reacting to temperature change

This is interesting stuff.... STU - I might need some of this info for the Technical Articles I discussed with you some months back!

My car run's at .76 lambda on hammer and I also have a Knock Guage that has been calibrated with DET CAN's.

I must admit, I am fairly regulary checking my lambda and Knock Guage.....

Yeah, no probs Shaun, keep me updated with links pal
