Thread: High egts & fuel consumption

Hi, can be due to many things but you'll not be able to properly diagnose it without a tester, watch the temp gauge, is it going fast to the middle after you start driving?, not very relevant as well but if it takes long while it's not cold outside could be low readings from the ECT sensor which would increase consumption, the AAP sensor in the airbox is important as well... test tdive it with that unplugged too...which is not 100% relevant again... better find somebody with tester and get some live data readings that's the proper way of diagnosing this cos it's definitely an overfueling issue

HMM, my first thought was.

Vehicle has a TRS remap,

The question is , was it doing it before the remap?

Don't know!

I purchased the vehicle interstate with the remap being done as part of the pre purchase/minor remedy work before it was shipped over.

On the advise from JC I've wound up the actuator nut on the turbo. Took 9 complete turns to get it to the point where it overboosted on the highway test. 1/2 turn back and its happy.

The fuel is brimmed so I will see how it goes this weekend with ~500km worth of highway work on the cards.

The same gradient @ 110kmph on cruise control was at 620c instead of 750c.

I am still able to hit 800's flat chat up a short hill but this is a bit of an unfair test but I can work with this.

Perhaps the decat pipe and center box removal I'm building up will help it further.

And what temp do you see when holding 110 when on a flat road?
Are you down on power or have plenty of get up and go?
How much black smoke you putting out when accelerating?
Are you sure the EGT reading is correct? I have seen Madman EMS give false high readings due to bad cable connections.

If you have access to a Nanocom, record and post the data from a run.

350-500 flat road at 110
A tad laggy to begin with - improved with increased boost. Overall power has increased a bit as well.

It disgorged black smoke prior and now I barely get a whiff.

2 different probes, 2 different gauges. Temps would be correct for idle etc - there does not seem to be any great disparity.

Hello phibbzy,

Check if there is any oil at the ECU(oil in the loom). I had a similar problem that was intermittent, no remap though.

Cheers,

Jason

Rocker harness is fresh, loom from engine to ECU is clear and so is the ECU.

This sounds better and yep , it will help upon removal of cat and centre muffler , while you're at it , change the 42mm ID flexi for one of the same ID as the pipe, after this you may have to go back another 1/2 turn on the boost modulator,
