Quick question...

I have a customer that was having an issue with SCT and a spare torque source he couldn't find.

Trying to help via HPT.

"Pre-ignition limit"

We found it in HPT... does...

I appreciate the advice. I see the other limits I'm hitting because I was trying things to get the desired load to increase.

So I know it's not technically a limit I'm hitting. But for some...

What's going on. Just picked up the new EB and figured id play around with it during the slow season at the shop. I had a 2017 explorer sport EB that I tuned previously for my wife. So I figured it...

livernois got in and successfully tuned one, really hoping HPT is hard at work on this...

Just looking for an exact answer or table to adjust to eliminate the rev limiter when launching. Followed by the huge reduction in torque management.

I did attempt to search and saw the subject...

So we have a 2006 300 SRT that we swapped a TH400 into. I know its been done before but trying to figure out a way to get this thing to start. Switched the transmission in the TCM tune to manual....

I appreciate it. Still working on the fuel MAF and fueling and put it on the street for that exact reason.

I really appreciate the help again.

I was working on scaling the MAF because of all the changes being made to try and diagnose it.

here was the final pull at 690whp

68750

thanks for the tip. adjusting now.



im at 15* right now. Working on smoothing out the MAF now that I have found 80lb of air all of a sudden haha. ill post one up after I smooth this out a...

***update***

it was the damn IMRC... even being in front of the air filter it was still creating enough suction to close em. Thank you everyone. you are all great

first pull with it correct...

***update***

so I check out the IMRC actuators. and they looked to be physically stuck closed. I pulled hoses off and there was a his of vacuum being release and I saw the arm drop. did a pull...

I think you are onto something. The voltage is stuck at 1.17 no matter what. Vacuum or no vacuum. And definitely overlooked the map points. The diaphragms don't move at all.



This seems...

I hate where the MAF is mounted. And have yet to see a tune from another Hellion kit on HPT sadly.

But that MAF is literally mounted on the intercooler end tank. Which in theory looks as if it...

its a single walbro 450 in tank pump. regulated by stock mechanical regulator. ill see if I can throw a gauge on it tomorrow to and verify its working

I haven't had it on the street with 10psi yet. at 6-7psi to me it felt like it was twin turbo. a lot different then a stock one. so I will be trying that tomorrow. I know spinning will cause MAF...

the reason for the MAF curve is because if I correct it according to fuel trims. It knocks it down to almost stock. Which I seems very odd.

and yes, verified multiple different ways both with...

it is connected to the air filter of one of the turbos. not on the boosted side



hopefully this helps. my scanner reset and I lost those points lol

yeah I saw that after I typed the message. I made the adjustment and no change.

I feel like that MAF readings are low. But the engine is seeing 10psi in the manifold... so confused

where are you seeing the load rows being .9 to 1.1

I see all timing set for up to 2.0

**edit** ahhh gotcha. I did miss that.

This is also not my tune. I am correcting the tune. But was...

I agree that's a lot of timing for the boost. but look at the load. its actually very low for 10psi as well as the MAF setting. and that being said its only at 390whp with all settings in place. im...

Wont go into too much detail, but customer came in with a supposed boost leak. Did a boost leak test and came back clean. did a dyno pull and verified it is pegging 10psi and holding strong. but...

I had it set to 60%. I'll try dropping it some more. Will let you know

I set all mine to 2.3. Loads don't go higher then 1.7-1.8 though.

Now battling an odd issue where it is staying in stoich fuel at WOT. Scared me at first but now I'm chasing that.

**update**

It was the "flange temo involved " setting. Adjust that out and I sure enough maxed out my MAP sensor haha.

Thanks for the help everyone

Yeah I set all of my load values to 2.3 as well. And tried the exhaust temp trick and it didn't work either. Gonna keep bumping things slowly to see.
