Thread: High EGT's

Hey those figures sound wrong to me. All I can say is that with my probe in the exhaust manifold itself (ie pre-turbo) I get 650ish and I can feel the engine complaining (power drop off). Usually I drive to 550 on the open road. Perhaps yours is over-reading somehow. What does it read when the engine is cold?

Mate, your figures seem all wrong to me. Hitting 995 degrees would mean major engine damage (think pistons turning soft). Seems to me you have a sender probe or an electrical misreading. If I'm realy lazy, I can hit 660. But that's with 23ft of caravan behind me.

I'd be thinking at those temps you'd have a nice molten blob under the bonnet, so yeah. I'm thinking a possible mistake.

Thanks guys

That's what I was thinking, especially as it has just started happening
Seems to read ambient about right, but it is definately showing higher that it used to
Will order another probe and install that, certainly makes you watch the gauge though

950 deg C and rising was the maximum EGT I saw, trying to see how high the temp would go(with a plug in chip installed)

The EGT sensor is installed according to Auber Instrument instructions. I have no reason to believe the sender or guage is faulty of sending false readings.

Plug in chip now removed

Can still hit EGT temps above the recomended 703 deg C with the foot flat to the floor but not the 950+degrees seen with a chip installed.

Cheers,

Mine has gone to 1050 degrees (pre turbo, foot down up hill towing caravan), will absolutely race up to 900, hate to know how long I was holding those temps before I put the gauge on..

Though now it is quite frustrating as there is no where near as much power while keeping the EGT's under control...

Standard ECU maxxed out at about 780 degrees

I have to say though, as soon as I take the foot off the loud pedal the temps race back down to zip.

These days I just use the power as needed and try to back off as soon as possible to prevent too much heat transfer.

Glad I'm not the only one with these excessive temps with chip/ECU re-programming...

P.S. Is an auto, have aftermarket flee flowing exhaust, D2a intercooler and new MAF.

The tip of your egt probe isn't touching metal? That is, pushed against the inside of the manifold? In my work, I see this a fair bit and it can give you higher than normal temps

Doesnt surprise me with a plug in/ piggy back chip. They trick sensors into allowing extra fuel etc.rather than let the sensors do what they were intended for. There is no way a Nanocom will tell you anything relevant with a plug in/piggy back unit.
IMO they are bad news for any vehicle.

I could never exceed 640 pre turbo on std ECU. With a MSB ECU upgrade reaching 900+ was easily achievable until the bigger IC was fitted.
Following the bigger IC 750 to 780 working hard at 130km and a trailer on a 40+ day wasnt uncommon. I had the alarm set to 750 and backed off when it activated.
Normal cruising the EGts were stable around 480

Check your boost is set correctly, IC hoses are good and not leaking, Air filter is clean.

cheers.
