Regarding tuning, and especially VTT and such, I intend on following up on that side in this thread, too.

Again - I'll report back over the coming weeks as I get more miles on the car. We shouldn't have to mess with the MAF if this method is what it is stated it is, even though the method outlined by Mike, to my understanding, has been used for a long time for meth', so when done correctly, is perfectly fine. There are LOTS of shops that have been successful, so there doesn't seem to be anything to be concerned about.

Ok well that makes me feel better. Looking fwd to the upcoming info.

I’m using FIC +30’s, 38% fuel lobe cam, Fore in tank setup. No meth, e60, holding 5.2MS @ .84 lamda. Inj duty cycle 28%. Just under 900 whp.

It doesn't seem like the table I'm doing this in is pretty general, and polishing with the PE table will help with that fidelity. And it sounds like once a good IPW is locked in, then I'll see about final polishing methods, like adjusting the REFLEX MAF curve to calibrate with the PI injectors. So - all of that to say: leaving the E92 MAF curve alone, adjusting the E92 fueling, and allow the REFLEX to make up for the difference, and get that EQ on the wideband in a safe range. So - yes - I think we are on the same page

I'm hoping this works out. I've tried to see if there's information, regarding this method, out there on HPTuners' forum, but I got no responses. Obviously - tuning is a big business, and I get that, and while the common compensation (I guess you'd say that?) method out there works fine, it seems like a lot more balancing and "raping" that MIGHT be necessary, if this method works out. We'll see

I'd also recommend anyone who's interested, to go through Greg's threads (all of the related ones) and to also focus on Mike's comments. There's a lot of information to unpack and think about, that are helping me along, too. They were especially helpful in finding a model to base plumbing from. Seeing how the fuel needs to flow correctly was a great help, because I would have never figured it out with the threads and Mike's videos.

Thx Radz, I've tried to make my posts so people will understand how this system works and the benefits of running Thpsi Port Injection with the Reflex controller. Not sure its sinking in.

I couldn't do it any better than you Greg

Geeezzzz, come on, lots of guys on here are smarter than me. Me just an old man that has never grown up.

No word on a ship date yet for the THPSI kit, but looking at fuel hoses and fittings in the mean time. Im waffling between ptfe and e85 compatible nylon braided.

Any pros or cons between ptfe and e85-compat nylon braided? Looks like laynlos are probably ptfe from the pictures, and I'm leaning ptfe, but so far seems like 6 of one half dozen of the other. Only drawback so far for ptfe is the ferrules arent reusable.

Stainless braided would look cool, but i dont really want to mess with that. I would like to do something to spruce up the engine compartment. It's all very OEM looking except the procharger itself. It could look interesting if i somehow brought some of that 50th Anniversary orange under the hood. Any thoughts?

The PTFE lines I have used in the past are a metal braid on the surface. The PTFE means there is a plastic type liner inside the line that is resistant to ethanol/methanol fuels.

Yeah, here's two pages that show the PTFE hose versus "regular" braided hose.

https://anfittingguide.com/install-b...hose-fittings/
https://anfittingguide.com/install-ptfe-hose-fittings/


There appears to be some "premium braided hoses" that incorporate a multilayered approach with some kind of E-resistant inner liner, a rubber middle layer, and braided outer layer. Assembles like standard AN hose ends and uses the standard kind of AN fittings...

Then there's the straight PTFE like in the second link.

I think I'll do the PTFE... I've done the braided hose before and the metal stuff looks nice, but sucks to assemble... I could get nylon braided, but it has to have an E-compatible liner in it anyway, so ultimately the plain old PTFE is the right hose for the job.

After I order, I'll post a manifest of the hose and fittings I order to make it easier for the next person.

[radz28]

Make sure you don't do what I did (because I didn't know any better) and get the PTFE-hose compatible fittings and try to use PTFE hose... Standard AN-type will NOT work the the PTFE Nylon hoses. I didn't know there was a difference in fittings.

It seems like PTFE hose IS the way to go.

Also - it seemed like it took a day to assemble my order, and was shipped a whole business day after. I'm only 400-miles away from THPSI, so I got it a couple days after I placed the order, so it will take a little longer for regular shipping for you. It you ordered Thursday, I wouldn't be surprised to get shipping information soon.

Fragola 6000 PTFE is my go to. Except I am running nylon from my T to the HPFP, so I will need the flexibility. It will just need replaced in ~ 5 years, which I'm ok with as it's just a ~6 inch section. It will also hopefully buffer out the NVH from the HPFP.

Is 5-years a general rule for this kind of hose, or are you just playing it safe?

Unless there is a product that is out that I do not know about, all nylon/kevlar/nomex hose is only rated (from the manufacturer) for 5 -7 years before it starts to leak (especially if you are running E85). Even the stainless reinforced stuff like FlexLP from Fore.

They did tell me the SC plates were "a few weeks out" before I ordered, so not expecting it to ship right away.
