Guest Terry S Posted September 5, 2002 Share Posted September 5, 2002 Hi guys, Has anyone whilst surfing found an EGT system that allows multiple probes. I am sure I've seen one somewhere. In an I deal world I'd like to monitor all 6 cylinders at once. Link to comment Share on other sites More sharing options...
Adam W Posted September 5, 2002 Share Posted September 5, 2002 This may be a bit "low budget" for your tastes, but how about putting the probe in the turbo inlet, ie where all six exhaust runners come together? You'd still get that all important pre-turbo reading, and it would look a lot cleaner than six probes, six wires, and maybe six gauges. Link to comment Share on other sites More sharing options...

Guest Terry S Posted September 5, 2002 Share Posted September 5, 2002 I already have a single EGT at the collector. I want to make sure that all cylinders are OK as MKIV's have been known to have a slight problem with #6 when highly tuned. With my new ECU I can put more fuel into each cylinder if required so it would be useful info. Pete??? Link to comment Share on other sites More sharing options...

He can output lots of basic readings onto one of his custom LCD screens. I bet he could do something with multiple egt signals. Link to comment Share on other sites More sharing options...
eyefi Posted September 5, 2002 Share Posted September 5, 2002 im sure ive seen one somewhere, but i cant find anything. i think it was called colossus or something greek and mystical. Link to comment Share on other sites More sharing options...
Syed Shah Posted September 5, 2002 Share Posted September 5, 2002 I think that people who moniter all six (in the states) all tend to have six probes and six gauges as well, although I am sure there must be an alternative to this, I have not yet seen one.

Rich J Posted September 5, 2002 Share Posted September 5, 2002 What you need is a small box that you can wire all the sensors into, the box could then take the highest signal (through use of electro-trickery) and send it to the standard EGT guage, add a row of leds to tell you which one has the highest temp and BINGO! Could also have a dial (7 position in the Supra's case) to pick the sensor you want rather than giving the highest (beats (in cost terms) having six EGT guages sitting on the dash ) Of cause you have to get someone to make the box for you.

Guest Terry S Posted September 6, 2002 Share Posted September 6, 2002 Thanks Rich. I was talking yesterday to someone who builds WRC engines about this. Apparently RS components sell suitable 3mm probes for approx. £15 each. They also sell a display that will allow 12 K probes at once. It has a dial so you can flick through the channels. This is OK but I really want a "real time" spread across the cylinders. I heard once of a system called a Heraeus but can't find any info now.

Guest Terry S Posted September 6, 2002 Share Posted September 6, 2002 Cheers Gaz, Still can't get access to the bit I want. At the moment my only option is 3 SPA dual Gauges, with 6 EGT Probes & adaptor boxes. This will be EXPENSIVE, so I am still trying to find an alternative.

Chris Wilson Posted September 6, 2002 Share Posted September 6, 2002 Originally posted by Terry Saunders SPA= £1100 expensive:eek: Some of engine dyno people supply multiple readout EGT meters, after last nights piss up I can't get my head in gear, but the American makers of engine dynos do one, the name will come to me, later, much later.... What you are trying to do is a VERY good idea, ideally you want to measure O2 in each runner too. Have you got a tubular manifold or something? On the stock cast one gas reversion occurs and individual and ACCURATE probing of O2 and EGT would be very suspect. I'd be very interested to read the spec on your car these days, have you any info on a web site or anything? What ECU have you gone for? Cheers.

Guest Terry S Posted September 6, 2002 Share Posted September 6, 2002 Cheers Chris, any info would be greatly appreciated. I have a tubular manifold now for my single. I have a UEGO wideband in the downpipe with an analyser in the car. Once it's up & running properly you will be one of my first port of calls to show you the car & to buy you a beer for all the advice. Link to comment Share on other sites More sharing options...
Chris Wilson Posted September 6, 2002 Share Posted September 6, 2002 What's the O2 sensor, a Bosch LSU? Are you running it closed loop? What ECU is it? If you don't want to say at this time I quite understand :-) I'd put money on you needing a LOT more ignition adavance off boost comaperd to stock if you have a big single and cams...?

Guest Terry S Posted September 6, 2002 Share Posted September 6, 2002 I'll give you the full spec when I see you Chris. The ECU is the one is discussed with you a while back, but I need to keep it quite at present. Yes the ignition is very advanced low down but the boost & torque curves are great. It makes 10.4 psi of boost & 328 ft lbs of torque @ 3000 RPM. Link to comment Share on other sites More sharing options...
Guest Terry S Posted September 6, 2002 Share Posted September 6, 2002 Chris I have looked on Dynojet & Mustangs web sites but couldn't see anything. When the fog clears can you give it some thought please. Link to comment Share on other sites More sharing options...
Rich J Posted September 6, 2002 Share Posted September 6, 2002 Seriously, I'm wondering how useful 6 guages are going to be, unless you have full data logging it's going to be hard to keep tabs on what is going on! I actaully think you'd be better off with a more simplified set up for driving about (e.g. one guage/warning light that shows the highest value) and a full datalogging device for diagnosis, that way you can keep your eyes on the road the single guage and let off when the warning light comes on. You could then use the datalogs to diagnose the cylinder and conditions it happened under at your leisure(rpm/load/timing/injector pulse width), would probably want the 6 O2 sensors logging as well, and the knock sensor. Of cause it won't be cheap but alot more useful than a bunch of numbers (it was hard enough to read on SPA boost/temp gauge whencaning it when I had mine nevermind 6 and the O2, and boost etc..) and flashing lights.

Guest Terry S Posted September 6, 2002 Share Posted September 6, 2002 The SPA's have peak hold so I could find if there was an imbalance with any cylinder. If ones peak hold were significantly higher then I could richen that cylinder up slightly to compensate. Does this make sense? Link to comment Share on other sites More sharing options...
Rich J Posted September 6, 2002 Share Posted September 6, 2002 Yes but at what rpm range does it need the extra fuel at? Datalogging is the answer.

Guest Terry S Posted September 6, 2002 Share Posted September 6, 2002 Whilst I do agree I don't think a system as complicated as you describe exists. I would richen it up at WOT via the TPS Link to comment Share on other sites More sharing options...
Graham Rudd Posted September 6, 2002 Share Posted September 6, 2002 If you have six EGT probes then why not buy a cheapish data acquisition card for a laptop and hook the probes up to that instead of the gauges, or maybe make a switch to switch them over. Along with an RPM signal that should take care of the data logging. Link to comment Share on other sites More sharing options...

Along with an RPM signal that should take care of the data logging. That sounds the best way, I know most of the serious engine people do it like that. Terry: The dyno I was thinking of was Super Flow. And I think they are from the Netherlands or USA. Wherever they make some stunning engine dynos and data acquisition stuff.
