2016 L83 w/LT4 pump erratic fuel pressure

[TriPinTaZ]

Currenlty, the LT4 HPFP is footing the bill with the increased 32% lobe. The FIC 30%+ injectors are staying fed at 2400 psi. Just attempting to solve the common P2635 code (which I disabled) and the modulating fuel pressure which I hope to remedy with the LPE check valve that wil be arriving this week. Unfortyunaley, one of the fittings will be next week.

I think 1,000 WHP in the Yukon in my signature is well enough. Drives like a stock SUV and gets up very well. Suprises a lot of people, even myself sometimes as I forget how much it has under the hood as it feels so tame at times. It's just money afterall!

So you're saying that you are at 1000 wheel HP with a stock LT4 high side at 2400 psi, 30% injectors and 32% fuel lobe on E85?

That is what I am shooting for but it makes what it makes. Bob @ FIC said do not exceed 2,500 - 2,600 psi as the 30% + injectors do not require as high pressures as the stock LT4 injectors. Keeping it low until I get it on the dyno for tuning.

The port injection controllers in my opinion just add too much under the hood and too much complication. I did look into competetors pricing and I could by another used car for what they were wanting.

For the price target we're looking at....that extra car would be a hooptie for sure. I think we'll be among the lower priced options...but the bonus is you just plug in 2 connectors, power and injectors in a plate kit. And no tooning to the controller. Just deal with HP Tuners on the ECM side and you're done. The convenience will be the selling point.

I'll be watching for updates and final product info. Sounds too good to be true with the plug and play as well as controlling with HP tuners. This thing is way more capable than the 16.5 psi I am feeding it on E85. If I get it all controlled with the current set up I wil be happy but there is always room for more.

You won't make it to 1000 wheel HP on E85 with this high side setup. You will run out of injection window for sure.

I am running a #16 nozzle using my stock washer fluid tank... like I said, it'll make what it makes. Either way... it's stupid fun and jaw dropping.

You'd think for the money I have invested in the current fuel system, it'd make me a glutenfree sandwich whenever I wanted.

I just relaized I put 1,000 WHP, meant to put BHP. Thanks for keeping me honest Tripintaz. I could only hope to see 1,000 to the ground but would I really want a 5,600lbs + Suv to have that much?

Yeah, I really do!!

I mean... my Camaro is on the dyno right now running about a 0.30 fraction all controlled by tuning the ECU. The port controller knows what the injectors are and knows exactly what is happening in the entire system... and figures it all out with a (soon to be) patent pending algorithm.

The days of drill bits and dip sh!ts are numbered. High side upgrades are going to be a thing of the past once easy port injection is accessible to everyone.

Sounds like wonderful news! Looking forward to the final product and some real world results.

After adding the upgraded fuel lines and the LPE check valve to my Yukon, the fuel is performing perfectly, no pressure drops at WOT and the fuel pressure is only about 8psi difference whereas previously, it was around a 25psi difference. Good enough for me!

The pics of the lines are saved as the GM part number

Cant wait!!

My first test will be can a JMS low side with the ZR1(2022+ ZL1 low side in tank), support the stock high side & the port system but running the smallest LS3 style injectors. Maybe like 38-42lb. This will be for all the clients that want to run stock cam, with X port blower with ~10% overdrive adn full pump E80ish without messing with the stock high side. I sort of expect the pressure to fall off up top so the DSX Low Side or in tank will be needed. But we will see!

LS3 injectors will be ideal up to 900ish whp (on blower applications). I'd advise people against going straight to a huge injector unless they know they need it. After LS3, ID1050 would be the next choice.

Man, you are really behind the times. You need to take some lessons from the business school/private equity playbook. What about... IaaS - Injection as a Service? Sell the hardware, then require a monthly subscription to unlock different levels. If they skip a payment you can remote disable the system thru the Cloud! Think like a landlord, dude!

(I am of course joking, though these things are really happening)

These are excellent ideas.

I'm assuming you guys are being sarcastic. Nobody is going to pay for monthly port injection as a service like you would pay for Tesla add on services. lol

Sure they would. Depressing, but they would. Or at least some of them would, enough that you could play subscription tricks or price-over-volume tricks and make lots of money off the suckers. Look around you. I don't own a TV or even have working phone service because everything is shit, but most people not only tolerate all the garbage but think it's pretty good, and the rest are resigned to it and figure there's no alternative and just go along so as to not be labeled as weirdo outcasts.

Weld Racing was able to triple the price of a basic, entry-level Draglite wheel and somehow not put themselves out of business. Comp (now Edelbrock, and all the others who are also now rolled up into Edelbrock) doesn't sell any cams that're less than $500, even if it's a stupid cast iron core hydraulic roller. I know production costs go up over time but they haven't tripled. People still buy Weld wheels and Comp cams.
