I don't know what that is, but I attached the oem and current tune if you want to look

I play with spark now and then, but wanted some input/opinions from others with an M278 or M157, like how far have people have pushed spark at full load?
Also, has anyone raised the MBT/Optimum...

I guess I'd play with those #'s and see what happens. The #'s seem really weird to me, I can't imagine what they represent.
I have no such option in HP for my car, but using a Launch X431 I noticed...

If the car is causing an issue, I can't help, but all issues I've had were the USB plug at the laptop or the USB cable itself. Any break in the connection to the dongle and it's game over. I have to...

Ic. Well, it is limited, but maybe tuning over the store bought tune may work better. Mine worked better if I tune over the OE Tune. If I apply the exact same settings over the oem tune, I lose...

I think my tune is pretty much maxed out, unless I want to push boost more. I have tinkered since the tranz tune, and managed to eek out a little more power the last couple months which shows up...

It was a remote tune using Tactrix. I'd assume they're all pretty much the same but that would be a big fat guess.

My theory is maybe they only adjust torque limits and oil pressure? If you were...

I had mine done and I regret it. Knowing what I know now, if you offered to pay me $3000 to put it in my car, I'd say no. I lost .2 sec on my 0-60 time and never got it back, and there is only one...

Update: After it seems nobody knows how to tweak the ECU to adj the stat, I did some tinkering and have it back to 180F (freeway). Temp is also more steady than it used to be, meaning it doesn't...

Unplugging sounds like a better/easier idea. Please post results because I'm rather curious now.

I'm also curious if you're going to fix the position plates? I'd dread pulling the valve covers,...

Oic now. I was too focused on how far the two numbers are off.

I suppose maybe HP has banks 1 & 2 switched? If so, maybe you're the first to notice. I guess you could use Xentry to check it,...

I'm curious why it would require tuning? Or are you referring to the CEL it will generate?

As mentioned, the BB dealie would take too long to warm up. I need my heater/defrost to work. Even with...

Damn, that's off a lot. I'd suspect the position plates have moved. Forgot the actual name but they're just pressed on and can/will move. I have one off ~1.5 deg and I thought that was bad... ...

I would run the oem tune just in case they decide to use the equipment they use in CA. I heard rumors they were looking for tunes, but nobody I knew had been caught, and even my smog guy said he'd...

It's electric. Or I should say mechanical with electric boost. Without the electric heater the water temp hovers around 217F, which I read online is the oem mechanical rating. With the heater it can...

I'm recording fifty things and it doesn't seem to slow it down. There is always a delay, but it's there no matter what.
I have an MPVI2, USB 3 cable into a USB 3 port

I too had an uncooperative O2 monitor before smog. I tried preheating the O2 by turning the key on for like 30 seconds before starting and problem solved, so maybe try that?

I'm in California and...

I don't suppose anyone has figured out how to control the little heater in the thermostat for M157 & M278?
I ask because my stat died and the new stat is holding temps 10-15F higher on avg than the...

I doubt I can help but it would be interesting to see that screen recording to show the mystery flicker.
I use Icecream Screen Recorder, after trying several. It was the easiest to use, least...

I assumed that. It was just an fyi that mine isn't limited so maybe something else is causing your problem? Maybe mechanical, or maybe some setting you did that you assume has nothing to do with it?...

I set my limit to 5k and it went there no problem. Fyi

Oic. Hmmm... I don't recall specifically ever revving this eng that high, but I think I have? It could also have been a memory from my previous car.
I guess I'd look at that Race Start # at 4500....

You can see here I set my P/N to 2k. Not sure which of those is responsible, just that I set all three and it most certainly works.

hardeet; I did not know that about the arrows. All my channels have two arrows, but to be sure we're talking about the same thing I attached pix:

And I jinxed myself. First time using my USB cable...

Hard to understand... So you updated to the latest version of HP, then your code returned? Hmmm. I can't say for sure what it is but I can say what I would do: Load it via the old software and old...
