2017 Corvette Stingray (Wet Sump LT1) Need Help With ?Engine Protection Mode?!

[Jhammonds]

Good Evening Everyone!

I had a quick question about my 2017 Stingray w/ wet sump LT1. I was at the track the other day and it seemed like every time I was exiting the same sweeping, right hand turn, I would trigger something called ?Engine Protection Mode? and the Vette would go into a temporary limp mode until I upshifted. I know it has something to do with protecting the engine from an oil starvation concern but it is way too sensitive and was being triggered way too often. HP Tuners was nice enough to send me a sample file of another Stingray and I noticed that under the Torque Management tab it gave you the option of disabling something called ?Lubrication Protection? and ?Oil Starvation?. Would disabling these turn that pesky ?Engine Protection Mode? off?

Don?t get me wrong, it?s a fantastic feature however it?s hindering the car on the road course.

Thanks Guys!
Jeff

You can turn those off or you can lower the values that trigger it, it is there for a reason though. I would be checking oil level or possibly overfilling a little bit before doing that though, personally.

Any time you're road racing adding 1 additional quart is SOP. Might be all it takes to cure your problem.

Hindering your car? That flags when oil pressure is lower than it should be. Don't turn it off. It's saving your bearings. Run better oil.

I?m pretty new at this.

...and you're about to find out the hard way.

Curious does your low oil pressure warning light come on? I looked at a couple '17 files both Vette and Camaro and both have lube protection disabled and oil starvation enabled. It sure sounds sketchy disabling that. If a customer requested it I would decline.

I'd suggest data logging it just to see what the computer is seeing. Would not be uncommon for the PCM to see something you don't see on your gauges.

I meant new to HP Tuners. Not new to the track.

And yes it is hindering because my oil pressure is around 35 psi on average coming out of that same apex.

I asked a simple question about HP Tuners. Not your opinion on track experience.

Oh sorry. I didn't know you were a track racer. Go ahead and turn that protection off. You know more about engines than I do.

I mean for fuck's sake dude. GM engineers test the Corvette on a track. Multiple sessions. Professional drivers. How do you think that setting is calibrated?

You need to understand the gravity of your stupidity. Quit crying about it. Stop trying to ruin your engine. Run better oil that can handle the heat and doesn't froth as much.

I know it's probably on that oil cap and I may even get slack for it, but stay away from Mobil if you're running it that hard. There are much better oils on the market that don't break down as bad with heat. Use to be good stuff. Not sure it is anymore from what racers and engine guys are telling me. Then as recommended run it a little over full.

Amsoil, Driven, Schaeffer just to name a few. I've had 2 separate customers now running Mobil either lock up motors or kill bearings due to heat thinning the oil down before coming to me for tuning. One got a junk tune where it was spitting raw fuel out the exhaust and was overheating due to lean cylinder burn while sitting in traffic. He said coolant got up to 225ish and he limped it into a parking lot and shut it off and let it cool. Fired it back up and was 10psi lower so he had it towed. Bearings nearly gone after having it towed from there and the engine torn into. The other granted had junk bearings, but same story, got hot then low oil pressure. Kept running it and locked up. Also before getting to me although tuning wouldn't have helped him any...

I would just google independent oil test for racing. Looked like there were a few write ups. Whether or not they were paid by one in particular, I do not know. I know I've got some big hp customers running Amsoil and Driven products. I've personally used schaeffer and amsoil. Both are good oils. Red Line is good if they have oil in your weight. All up to you and what you decide on. If you're trying to keep warranty for any reason, don't touch the cal and let them change the oil and use their products even if it's not the best suited.

A lot of G-forces in corners on a road course and hot oil slings to one side or the other pretty quick.

Also not saying Mobil is bad, just that there are better products out there for high temps. I've personally got 100 some quarts of 5-30 Mobil still from where I was changing it in my older Jeep every month that I'm still slowly dwindling down.

Absolutely. Mobil 1 was good, relatively speaking, in 2007. It's pretty trash oil. The only decent product they make is 0w-40 Euro FS. Schaeffer's has an excellent additive package but poor film strength. Amsoil is Mobil base stock with a custom additive package. Quaker State 10w-40 Euro is where I'd start the bidding if you're on/off the track. Pure track there's specific oil such as Valvoline 20W-50 VR1.

I have some dedicated track guys that swear by this stuff.

Motul was the other one I was trying to think of when I was typing the last one up. I've heard good things about it too. The guy that overheated and killed his bearings swapped to using that oil in his vette.

[SiriusC1024]

That's an Ester oil. Not compatible with mineral oils. If you switch you have to do a few drain/fills to make it pure. Don't want the stuff mixing.

Good to know
