How does using DFI produce more heat?

Excellent question,.... Turbos?, higher compression? Getting driven harder?, LOL.....

GDI engines can run quite lean compared to MFI or PFI engines, so the combustion process would create more heat.  Add a turbo to GDI, and you can run even leaner, making the combustion gases even hotter.  That's my theory and I'm sticking to it :D

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

Yes, and that makes sense.  It also makes sense that having a turbo (or two) would elevate overall oil temps.

However, the question is more fundamental.  In just using DFI, how does that increase temps?  Running lean would, but that is a consequence of programming fuel ratios, not necessarily DFI.  Perhaps I'm reading too far into the shtick?  Just at face value, I do not see how DFI alone increases temps.

It was my assumption that a performance tune would run the car a little leaner at idle,which might benefit somewhat.  Z

Actually I've been studying egts and its not quite that simple.

If you don't believe me let off the gas and put your car in decel fuel cutoff than watch your cat temps plummet. That is the leanest mixture you will see yet the lowest cat temps.

I agree, its not that simple. 

But I think the cat temp is the wrong metric in this case.  The deciding factor for that is exhaust flow.  During decel, RPMs are decreasing which means less exhaust gas is hitting the cat.  I think that, because this is about engine oil, the graphic is referring to engine temperature.

I'm thinking the "DFI" part is more of a testament to Amsoil holding up very well with fuel contamination at play, and the high heat is obviously an issue in our twin turbo application...30 seconds after startup those DP'S are ready to cook stuff.

Yeah I've been trying to figure out the relationship between the two...

The problem with that is every time I'm researching something, SHOdded, AJP, Rich or someone else posts something interesting that sends me on a tangent, lol. One of these days Firefox will crash from the amount of open tabs.
