Livernois Firestorm HPFP Installed

[StealBlueSHO]

So I suspected there was a major change to the tune as it took forever for the tuner to update my ECU... so I double checked my strategy and SWPN on the ECU... found this to be humorous...

OLD Strategy: KHDR6KJ
New Strategy: KHDRLME

OLD SWPN: GG1A-14C204-APE
New SWPN: GG1A-14C204-LME

Looks like Livernois had to develope a whole new strategy and SWPN to properly tune the HPFP... cute that they tagged it "LME"....

In anyevent, there is most certainly a change in how the motor sounds.. specifically from 2.5K to 4K RPMs its much more throaty... even compared to the standard V11 tune... makes me wonder how much they changed...

I really think that if LME is developing their own strategies and firmware for the ECU... that kinda ends the debate on if they have more access into these ECU’s.... just thinking...

Hardly ...it may have just been the easier thing to do...but who will ever know

Can it be done with the SCT software? I have that question into Matt as well... simply curious.

Changing the strategy and fuel pump ? Yes, and I don’t see why not

 

[StealBlueSHO]

So I noticed after installing the new pump and new tune that the engine really sounded aggressive between 2500 RPMs and 4000 RPMs. This caused a bit of vibration through the cabin... very small but noticeable mainly through the accel pedal. Thinking I had dorked something up I went ahead today and pulled the pump and put it back to stock. Vibration and aggressive tone went away in stock form.


I am gonna ping LMS but I’m sure it’s probably normal as most people wouldn’t notice it...

Will follow back..

So I have been waiting to get my hands on one of these for QUITE some time. On my 2010 I ended up going with the Alky Kit to resolve fuel pressure issues since the HPFP upgrades were not available. However, on my virgin 2016 I decided to pull the trigger. 

A BIG shout out to Cody over at LMS for answering my questions, putting up with my canceling, then calling back to place the order, and the 5 different tune revisions I asked for. Then for answering a couple quick questions for the installation.

Installation was super easy, if you follow my how to on the HPFP replacement, its pretty much spot on... a couple changes...

1: You will need to bend the high pressure fuel line SLIGHTLY up so it will line up with the new pump
2: The electrical plug needs to be unbound from the taped up wiring harness. This will include cutting back the tape to free up the plug so it can reach the new pump.

Those are the ONLY two differences between putting in a stock pump and the Firestorm pump. Silly easy..

Initial datalogging shows MUCH more stable fuel pressure, fuel pressure is holding desired where as before it was dropping well below 1000psi which is downright dangerous if sustain, which is was.  The car drives really realy well.. smooth, pulls through the RPM range smooth.. very happy with this purchase and support from LMS.

Glad you were happy with our product and everythings running smoothly and install was very easy for you, this was our goal! Keep us updated!

You should probably read the last post...since he encountered an issue with vibration/harshness

I would say "harshness" is a stretch.. I did some more testing on it. I believe its due to them adjusting the strategy to compensate for the HPFP. The engine sounds aggressive during that RPM range and you can feel it through the pedal a bit. All the vitals are good..

Imagine going from stock to an aggressive tune, the engine sounds different, pulses differently and you can generally "feel" the difference in how the motor vibrates under load. Its very similar to that.

After going back to stock and then back to the HPFP setup, I am not worried about it.

I have the same "issue" with my V11 (FP command adjusted higher) tune... Feels like exhaust vibrations in the body (or even bad motor mounts even tho they are in fact good). Mostly at WOT or heavy acceleration... The car has been running fine for a couple of months now so I think it's just a "side effect" much like the change in the exhaust tone..

 

[SHOdded]

Either need beefier motor mounts or better fuel pulse dampeners or both.

Hhmmm...a very tempting upgrade. Not sure my wallet would appreciate it. To what end would you deem this upgrade necessary or even highly recommended? That is to say, at what point in making other modifications would you say that picking one up is in someone's best interest?

Depends on your goals. I would say that if you are running an aggressive 93 octane 3Bar tune the benefit is added safety and not worrying about low fuel pressure during the winter months. Necessary, probably not as the community has been running 93 octane 3bar tunes for 8 years without an issue.. but as the tuners get more out of 93 3Bar tunes, its a safety net. You tend to see quite a few posts about hesitation etc during the winter.. mostly because of fuel pressure issues from what I have seen..

If you are looking for BIG power and don't want to deal with methanol injection then the pump is absolutely necessary for RELIABLE power all year round in my opinion. Bigger turbos will benefit from more fuel as well so there is that...

Again, there have been guys running heavy mixtures on stock fuel system if tuned correctly for it... just depends on how comfortable you are...

Wish I had a better answer.. if LMS gets back to me on the E-Mix tunes then that would be a huge benefit. Knowing Livernois for their reliability, if the back an E20/E30 tune that upped the power, then thats a huge benefit in my book.

Just read this and I think this is a great thing. I will add it to my list of to-dos. Maybe one day there will be a transmission upgrade too.

Soooo I have had this installed for some time now... and I have purchased a lot of different stuff between my 2010 and 2016 SHO...

THIS BY FAR  IS THE BEST PURCHASE BESIDES A TUNE I HAVE MADE. That is all.. continue with your regularly scheduled programming...

204kpa is demanded but actual is higher... and GOOD spark up top.. but there is NO drop off in boost at the higher RPMS even with LMS extending the shift out. Very cool how well LMS can hold the boost all the way out...

I guess what I am saying that demanded is almost like a minimum...  this latest tune from LMS is nuts.

 

[ajpturbo]

Well the boost has nothing to do with the pump ....as long as the turbos are good ...I think you have an overkill pump for your boost level but it’s your money....some people won’t have much of a fuel pressure dip at at 200 kpa...as long as you feel good about it that’s all that matters...temporary fuel pressure dips do not automatically mean KR. ...you have octane with e30 so 1500psi fuel pressure is fine and the pumps typically run more efficient there

When you say actual tip is higher do you mean tip? That will be higher than map when the throttle is closing to control boost

 

[ajpturbo]

Well you need to see how nuts it really is and get that beast to a dyno! I love LMS but the dyno numbers always seem to be modest

 

[StealBlueSHO]

Hmm I will post some logs later... unfortunately all the AWD dynos are unavailable in NoVA until sometime next year. Moore’s Automotive in Fairfax is broken (I called) and Ptuning in Manassas, VA stopped offering dyno pulls due to the large tuning demand...

Anyone else knows a linked AWD dyno within a couple hours drive let me know...

But the track numbers will tell the whole story...
