Default Installation Instructions? - 08-21-2021, 06:28 AM

I am looking to pick up the CPI kit, but generally look at the install first to see how difficult/damaging it would be. Is there a link to the install for this product?

It’s fairly easy hookup. If your using the stock intercooler, you will need a 1/4 npt bit to make the hole for the injector for the charge pipe. (Passenger side) .
You can follow the diagram on the top of the thread. Also for the FSB controller, same instructions for the water/meth kit.
Only thing you have to usu caution with it the tapping of injector and making sure the pins are in the correct spot.

Just the photos in this thread.. We've been meaning to make a better guide but it's a fairly easy install.

Is there any benefit to this when running E30? Or do you need E50 all the time? When you drive on E50 you only get like 11-13mpg,

You can run up to E50. You don't have to run E content at all though. You can still run straight 91.

The whole advantage is to run more E content which will raise overall octane level allowing you to run more boost and timing (not having timing corrections). Also relieves pressure on the HPFP and prevents it from crashing due to too much Ethanol.

The sweet spot I have found is E40-E45.

I didn't buy the car for MPG so can't tell you what I average. If i had to guess... 15mpg? But I have a heavy foot

Yes, you can run E30...if running 91, I'd turn off CPI. Agreed, E40 is where you want to be for optimal performance.

The purpose of CPI as mentioned is to assist your HPFP so it doesn't crash and keep your trims from maxing out.

Just ordered the CPI kit and EWG wires and will be here tomorrow. Wont be able to get it installed for a bit but had a quick question on plugs. Currently have a 2018 GT2 AWD Stinger with AEM intakes, MBRP Catback, JB4 with fuel wires running the Denso "1 step" 5346 plugs gapped to .022. Should I switch to the Denso 5347 "2-step" plugs when I install the CPI kit and EWG wires or will the 5346 be fine. I have noticed some pulled timing most noticeably on the number 4 cylinder when running 93 octane on Map 3. Thinking the 2 step plugs with the CPI is the right way to go but wanted advice.

Logging will tell you if you need to. I run a heavy set up and the 5346 work well for me.

For putting together the injector there were two extra black o-rings in the package. They appear to be close to the same size as the o-rings that were already on the injector. Are those spare o-rings or are they used somehow?

Is the protection diode that is included needed for the CPI application or is that for just the WMI pump? If it is needed how is that hooked up?

Thanks for any help you can provide. Excited to get this installed and get back to the track

1) For the nozzle placement further from the throttle body is better, but anywhere along the chargepipe should be fine.

2) Might be an oring for the assembly that screws in to the chargepipe, been awhile since I packed one of these so not 100% sure what they include these days.

3) Just for WMI pump

On a side note, If you put too much E85 in (above E50) you get a lean code and JB4 wont connect. Has happened twice now. Had to drive around for a bit and then put more 91 octane in.

Then its a weird process. Have to disconnect JB4 from the car, start the car for a second, turn off, reconnect JB4 then start it up again. Then JB4 will allow you to connect to clear the code.

Can't think of any reason for the JB4 connection to be related to E85 mix. But you will get a lean code from the higher fuel trims at idle.

Got my CPI installed today and am trying to update the firmware over the serial USB. I'm showing under the website a 21 - Kia/ Hyundai that I assume is for the 3.3s but it only has a firmware 21 or 24, also having tried both neither is successfully writing to the JB4, any suggestions?

Got the CPI kit installed recently, and Terry has been such a great help with checking settings, logs, and giving guidance on adjustments as needed. This is an absolutely great product, and easily tucks away in the engine bay out of sight, although it looks pretty cool too! I was really worried that the fuel pressure crashes would persist, but this solution really does solve the problem! I put the car on the dyno today, and ran on maps 4,3,5, and 0. Solid runs and fuel pressure was rock solid, no hiccups on the dyno.

If you're wondering about the NPT port, I bought one off Amazon for a few bucks and found a local shop to weld it into my intercooler piping for $20, so it really isn't a big deal!

Thanks to BMS for the excellent support and customer service.

P.S. Couldn't figure out how to add picture of the dyno result, but between maps 3-5, the results were close: 450-455 HP / 515-520 TQ & map 0 made 404 HP / 433 TQ

For those that are running the stock intercooler and don't want to weld something to the charge pipe. You can use this on the Rubber house that connects the intercooler to the charge pipe.

I've used those before and they always eventually leak. I would not suggest it. The threads are also really tall so may impact fluid spray pattern out of the injector.

I have a few questions regarding the CPI kit install and usage. Thanks in advance in particular on the first question due to my ignorance.


1. Does anyone have any tips or recommendations when it comes to installing the injector in the holder? I've only ever worked with injectors on a fuel rail, and only on a single car at that, so this was a bit unfamiliar to me when I attempted to install over the last couple evenings. I tried to find guides, videos, read through some forums, but still wasn't totally clear.

Primarily, I wasn't sure how far down the top of the holder needed to go on the injector or how precise I needed to be with screwing in the bolts to the same level.

The injector came with three o-rings on the spraying end, though I believe I only needed to use one of these, correct? The two black ones seemed to have a better seal in the holder, for what it's worth, so I used one of those.

My first pass at the install ended up with quite the fuel leak when I turned on the car! I believe I tightened the top too far down, and/or perhaps had it askew just enough so the o-ring wasn't sealing properly.

I re-did the holder, did not tighten the top down as far as before, and took extra time to eyeball that the top was level but still had very little play.

Thankfully, this was leak-free after about 10-15 minutes of idling, but I still wanted to be cautious and ask in case there is anything else I could do better or check to ensure leak-free operation long-term. I am admittedly a bit paranoid since my first attempt ended poorly and because I can't easily check for leaks with it behind the bumper cover.


2. I saw one user mention some settings that were not listed in the first post. I wanted to see if these are something I need to apply, as well as ask in general if there are other settings to apply or change for CPI that might not be in the first post:

Set Boost additive to 75
Set Signal scaling to 98
Set Min flow boost to 9.9



3. I haven't yet been able to do any runs for log gathering, but I wanted to ask in advance if there is a way in the app or logs to tell if CPI kicked in and is working properly.


4. Terry, do you still want users to email you logs directly for next steps, or would you prefer they be posted in this thread?


Thanks!

On logs either way! Email is usually quicker as I don't check every forum thread regularly.

CPI logging is disabled, set meth scaling = 98 to enable on the WMI page. I noticed that isn't in the first post so I just added it. But I can tell from the log its flowing as expected looking at fuel trims.

On leaking anything going there needs to be addressed, if you need help send in some install photos, perhaps we sent an incorrect adapter?

Thanks!

I have another question. Since installing the CPI kit with FSB, I've noticed a sound on starting the car, normally or in accessory mode, during the system check. It's like a burst of three mechanical buzzing noises is the best way I can describe it (if listening in the engine bay). It's audible in the cabin, but sounds more like a light thumping sound, and can be lightly felt in the steering wheel.

Poking my head in the engine bay, it sounds like it's coming from the general fuel pump area where the flex fuel sensor and fuel line tee are installed. With the FSB cover off, I see the board LED lights up in the same burst pattern and is synchronized with the sound.

I have not yet noticed anything out of the ordinary beyond this, so my best guesses so far have been that it's a byproduct of the teed fuel line, similar to a water hammer or other resonance when the pump turns on, expected behavior from the FSB and injector, or that it's entirely coincidental and unrelated to the CPI kit and fueling in general. Maybe it has always been there, to some degree, and I only now noticed it due to post-mod hypersensitivity.

Either way, does this seem normal? I can try to get a short video if this seems unfamiliar.


Thanks for clarifying the meth scaling setting. I've adjusted that and see the change in data now in some short logs. I will try to get logs on longer runs soon.


I still have not seen any signs of leaking with the injector or holder since I last posted, but I am still keeping a close eye on it. Looking at other pictures in the thread, the holder looks the same as the one I received and installed. So far, it really seems like I somehow managed to mess up my first attempt at install is all.
