That's what I did today. You could also use industrial Velcro which I intend to do again. I had originally attached to the front of the fuse box and that worked fine. Decided to move it since I'll be racing in some pretty high temps this summer so thought I'd move it a little further from the exhaust.

[radz28]

I did what King' said. It's temporary, as when I pull the front facia off, I want to move the TCM to where I can access it better, and I want to move the REFLEX and the DSX more out of the way and sight. Anyways - if you look up Matt Peckam's YT, I didn't know it when I did it, but I didn't realize I mounted it similar to him, so KUDOS to him.

I like Mike's method if you aren't contending with what I am. Super easy, and super accessible for flashing.

[radz28]

I might be making slow progress with the tuning, too. I've only got a single WOT hit so far, though, so I'm not making this an official update. I have some fuel pressure and knock stuff I'm trying to break down, too, but the way the E92 is behaving and the REFLEX supplementing, seems promising.

After getting some guidance, based off my input (whether my input was right or wrong is yet to be determined...), but it is my understanding that I may be close to where I want to be on 91 (E10) only. I've been saying I'm targeting 5.0ms for the DI, and I'm only at 4.0ms right now. It sounds like once I'm running full pump E', that my IPW will likely shoot to about 5-or-so, so it seems like I should keep it here. With only updating [33355], and leaving my E92 MAF and even PE where I had it set before, it seems that there is a fairly good chance I might not have to manipulate much. I have been pulling fueling from the REFLEX MAF (because I had all of it's PE-related settings pretty much matching the E92 PE stuff) only, and it seems to be following what I'm trying to do. I expect to be within a few percent of my commanded EQ the next time I can make some hits (almost a week of rain in the forecast at the moment...), and that's encouraging. But - I'm not certain my other little issues are related or not.

With the DSX low side, I'm seeing a big spike in fuel pressure when the pump turns on at 3-psi of boost. No biggie, but I want to try to smooth that out some, because then it seems like the OEM low side drops pressure, and then the whole low side falls. So it spikes to about 81-psi for a moment, and then if falls to about 60, and ramps back up to about 70-plus, and hangs out there, for most of the rest of the hit, BUT DOES fall slightly to about 65-psi; and creeps back up the last few hundred RPMs to about 70. I know - a lot, and probably not anything new. So - I'm trying to figure out how to minimize the spike-drop and smooth it to maintain 72-75-psi for the whole thing. I'm not sure how this might impact the E' side, so I'm a little concerned, and maybe for no reason, as, after all - I have PI for helping. I could be lost in my thoughts, so sorry.

And - I'm fighting a little knock retard. I AM on 91, and it's not a whole lot. This sounds strange, but about half the fuel in the tank is probably a few months old, and the other half is from the pump a few weeks ago. So there's that. My fueling doesn't go lean, and I'm not sure it's so rich that it's knocking from too much fuel, but my EOI is about 200* and SOI about 360, so I think it's more low-octane related, as far as I can understand. So - it may have NOTHING to do with this little exercise.

So - as always - comments and even help is welcome. You all know I'm no expert or anything close. I've learned a lot from many of you. My research continues, and I hope to report back with some more concrete information when the weather improves.

When Mike wired mine at the LS Fest (in the dark with 2 flashlights) he wanted to move mine where yours is and mine is now, but with the short period of time we had it was easy to just Velcro and wire tie it to the side of the fuse box. I think it's better where we have them now, especially if you run headers since it generates so much more heat under the hood, it's possible the Reflex could absorb some additional heat. Don't think it would affect it but better to be safe.

I think I was thinking along similar lines. That - and moisture. On the fuse box seems like a great location though, and the box seems pretty dang sturdy. I meant to comment on it's construction, but don't recall if I did. I like it's a nice metal box. In the video and pictures it seemed like plastic, but I felt better after unpackaging mine and seeing it was metal

It is sturdy and well-built besides being waterproof it's a pretty stellar product. I'd say the headers would be the only thing that could affect its performance if placed too close to them when mounting the Reflex.

When i put the dsx aux pump in, i had to change some settings in the fuel system controller. I would get the same thing as you are describing. The solution is in my big "results" thread from last year. Im on my tablet right now or id search it up for you (PITA on tablet), but i did whatever KingLT1 recommended to adjust *I THINK* max desired pressure in the engine and fuel system controllers. Two tables, same purpose. I think what you are seeing is the fscm slowing down the in tank pump because it thinks max pressure is too high. Ill try to remember to search it up later. PM me if I forget!

I would like to see some kind of plug or cover for the usb port. If even a drop of water gets in usb ports on a regular laptop/pc, it will fry things. I would imagine that if i plug in the usb to the reflex if it had moisture or even just dust collected in it, and then plug the usb into the laptop... damage could occur.

Not sure if that usb port is water tight to the inside either. Ill probably end up putting some electrical tape over it just to keep it clean and dry.

I believe it's common for the fuel pressure to spike some on the hit with the DSX. Don't think it's going to hurt anything. The drop might be tuning related. Make sure you have your desired fuel pressures set properly or you will get fluctuations barring it's not a supply issue.

Another thing you might be seeing is the dsx activating before the PI, so pressure spikes, then drops some when PI activates and has to recover.

The knock is definitely due to the 91. Even the LT4 doesn't really like 91 octane. I would remove timing out of high octane until it goes away and add what you subtracted to the flex spark table.

OOO!!! Thanks for the tip!!! I'll hit that thread. Thank you for letting me know!!!

I was thinking along similar lines. I figured - if nothing else, I'll schmeer some liquid tape over whatever areas I was concerned with. Ghetto - sure, but it might not even be necessary, though, I don't need to take that chance if it takes a little bit of effort.

Thank You, too, for commenting. I am currently farting around with that table, in addition to a couple others it seems might help with the spike. BUT - as you already said: it probably doesn't hurt anything, because the spike, literally, is momentary, and then the pressure falls within, like, a second or so. So - as you pointed out - probably not much to worry about.

I hadn't arrived to think about the pressure fluctuations when the PI comes in. I have to admit, with only one good WOT hit so far, it's hard to see transitions, because the FPCM just goes straight to high pressure commanded, so I have a lot of transitional driving I need to do I think. That's an excellent point, though. I think if I can keep the pressure from falling much below about 70-psi, and just maintain right above there, maybe I'll feel better. I'm sure this is all just my nonsensical logic.

Yeah - even using Magnuson's canned CARB tune, I was getting a fair amount. Of course - I'm sure my CYLINDER AIRMASS is a lot higher, as I'm seeing 16-psi because of high BARO pressures and the 103/RFBF combination. I'm getting into the 1.6s of airmass on the SPARK table, so you must be right, as usual.

Thanks, again, King'!!!

I mounted it where you have it but I just don't like it there. Been messing around with trying to figure out where I can mount it. Just bulky with all the wires and additional plugs that aren't being used. If I can't figure another spot I'll probably go back to the fuse box. I don't have headers so I'm not as worried about the heat since the exhaust manifolds have heat shields. I'd like to mount it on the shock tower but the big red positive cable is in the way. I'd like to see where some others have mounted it.

You'll want an equivalent hose to use for the list of fittings below, so look at this example (SUM-240606BP). If I were to do it again, I WOULD do the PTFE nylon hose, AND use the corresponding fittings, because I guess they're better at keeping sealed up and what not. But - the hose, suggested above, is rated for E85, and more, so I guess I'll find out if it's bad or not.

Some clarification on the hose... PTFE is polytetrafluoroethylene aka Teflon. The part of the hose that carries the fuel is PTFE instead of nylon. It resembles refrigerator ice maker plastic tubing. The line is then wrapped with a steel braid, and then finally with an outer black nylon braid, which is purely for looks. Mainly clarifying that PTFE is a different kind of "plastic" than nylon.

Thank you for making that clearer. Obviously - I screwed that up

Asked the question for you, and MOTIV said the the usb port is waterproof. I leave a cable in mine, but I'd think that covering it would be a good idea if there isn't a cable in it. I'll have to check to see if there is a plug that could be used for this.
