One of your torque source pids should tell you if it's in idle mode or not. That will tell you if it's related to the missing brake pedal input.

30 seconds of run time is not near long enough to make a consensus. Engine isn't up to operating temp.

Put it back in closed loop and use the fuel trims to dial it in. Run it for MUCH longer...

I don't check anything that's not a higher HP engine that I feel REQUIRES added attention. And even those I'll rarely move. It's more about making sure the valvetrain is perfect.

Changing a cams...

Unless you're experienced in degreeing camshafts, and have checker springs, degree wheel and dial indicator, it's a waste of time. Chances are you won't do it correctly if it's your first time...

Not sure how you misunderstood. It's pretty clear what I typed out.

It has a bunch of codes including ambient air temp and brake pedal position and the brake pedal code is current. Wonder if that's causing any additional airflow like an off idle adder, throttle...

One of the reasons to post a tune file in situations like this is so we know what we're dealing with. "6.0 4L80e combo" covers a lot of year/make/models.

Might want to post this over in the trans...

Crank relearn has nothing to do with it running rough.

That's exactly how the system works. Not sure how that's a rip off.



I think that's a fantastic idea. Go spend a grand on an aftermarket ECU and another few grand trying to get it to play nice...

All 3 of these files have max pressure enabled. So I think you're incorrect in your statement. Your own explanation says so.

The exact way you describe the situation in the paragraph I quoted is caused by NOT turning off the max line pressure. Read that paragraph again. That tells anyone who does this on the regular that...

It's going 100% wide open now. You have way too many throttle position pids and some of them are incorrect.

You aren't logging any trans pids so if it still feels like a dog it might be in the...

This another guessing game? Should I break out the crystal ball????

Because stoich changes according to alcohol content.

Go to Trans diag. Set your max line pressure for DTC P0101/2/3 to disabled.

450 pump in a returnless system, the pressure is probably through the roof.

Min pulse width looks too high for that big of an injector.

Transient min fuel mg is too high.

VE is too high.

Need to check your codes when you get it running and make sure P0103 is set. If it isn't, you're not in speed density and no changes you make will have any effect.

Says on their site they recommend the .660 Platinum springs and it has those specs on the product page. [email protected] and [email protected], [email protected].

I'd recommend using their "tip saver" kit as well. They're...

The only thing that's varying to any degree is the fuel trims. There are no timing swings, the MAP is even pretty steady so doesn't look like a ton of reversion. There's nothing that looks like...

Could be too much fuel or not enough airflow or a combination of both. First thing to do is check the fuel pressure. Unless you know what it is you don't know if you're "tuning around" a mechanical...

Alot of them have that same multiplier.

When I posted this ^^^^ I had looked through his 250 pids for a wideband and couldn't find it. That's why I referred to the narrowbands.



After reading this I went back and looked again and yes...

Looks the same to me.

All GEN4s (except E40) take 4x/58x. Only 1x cam gears for GEN3 and E40s.
