Introducing our new Kia Stinger/Genesis G70 charge pipe injector (CPI) kit



Install Guide: https://www.jb4tuned.com/instructions...on-Install.pdf

For those running E85 mixtures and higher boost levels, the factory high pressure fuel pump has proven to be a limiting factor to performance. Previously installing water/meth injection was the only way around this limit but the Fuel-IT CPI kit now offers a clean and easy to use alternative!

CPI adds a 7th fuel injector in the charge pipe, similar to a water/meth nozzle, only rather than having a separate tank/pump it's attached to the factory low fuel pressure system. Fuel is metered via JB4 FSB integration or a stand alone AIC6 fuel injector controller. The result is an additional 75-100hp worth of fueling capacity! Just enough room to max out factory turbos on E85 mixtures!

The full kit includes a Fuel-IT flex fuel sensor for precise E85 readings allowing the JB4 to meter CPI flow appropriately. The CPI kit features a CNC machined injector holder, quality AN fuel lines, and all required fittings for installation. Requires a 1/8" NPT bung with adequate clearance for the injector housing. For those running a BMS intercooler, the included 1/8" NPT bung placement is ideal. Note CPI can not be installed with the BMS MAP sensor WMI nozzle adapter. You can drill/tap an 1/8" NPT hole on your factory chargepipe if needed.

https://burgertuning.com/products/fu...ection-cpi-kit

Note kit includes two thicker orings which should be installed on the injector in place of its existing orings.

JB4 Wiring for CPI:

FSB: Attach per WMI guide. blue #16, orange #3, black good chassis ground, yellow CPI injector harness, green NOT USED, red fused/switched 12v power.

Flex Fuel Sensor: Attach per install guide. white #4, black good chassis ground, red fused/switched 12v power

JB4 Settings for CPI:

Update to v23+ firmware in the app

User Adjustment Page:
Set fuel bias to match image below (this will control how much CPI is injected peak at that engine speed)
Set meth trigger = 1





WMI Page:
Signal Scaling = 98
Bit0: JB4 2/3/4 Flex Fuel ON
Bit7: Enable WMI Pump PWM ON

This is pretty slick Terry! Not sure if it's worth swapping out current WMI... Advice or opinions?

[Terry @ BMS]

Correct if you already have WMI then this would be no benefit to you. This is perfect for the customer who has E85 access and does not want WMI. It lets you run E30-E50 and max out boost, where you would otherwise be limited to E30 and less boost due to the high pressure limitation.

[djerickd]

will there be a custom map for this I'm assuming..?

[turboAWD]

So, basically, this lets you go from E30 to E50 (stock otherwise except for intakes)? Sounds like, for an easy fit, should pair this with the BMS intercooler, so around $1500 total?

What about the HPFP / LPFP pumps on khartunerz.com? I heard those would let you also go from E30 to E50. If we combine the two systems, can we get to running E70-85 straight? I don't even necessarily want "all the power" available from E85 (might be too much for the transmission) - I would be happy filling up with E85 and running at E50 power levels, but not having to mix all the time.

Yeah, it would be a BUNCH of $$ so I'm not likely to do it, just curious. Trying to avoid getting too far into the mods with this car.

Also, I assume EWG wires are a must with this setup?

[Terry @ BMS]

It can be used with any of the JB4 maps, but we'll be working with customers individually to dial in the tuning initially.

Correct. The LFP isn't a restriction so save your money on that. An upgraded high pressure pump would render CPI unnecessary but they're not very proven IMHO.

If budget is a concern rather than our IC just drill/tap your factory CP for 1/8" NPT or remove it and have a nice bung welded in.

[turboAWD]

Correct. The LFP isn't a restriction so save your money on that. An upgraded high pressure pump would render CPI unnecessary but they're not very proven IMHO.

Sure, but together, would they allow for full E85 straight from the pump? Or is it still not enough? That was my question.

[Terry @ BMS]

No because for more than E50 the fuel scaling in the flash would be the limiting factor. Wouldn't run right without a proper back end flash map. And with a proper back end flash map and CPI you could support straight E85 without the need for WMI.

Thanks. Ok, so it's an ECU limitation. Got it. As in - probably never.

My question was actually about CPI + HPFP, not CPI + WMI - apparently I suck at asking clear questions.

[turboAWD]

Ok, a different question.

With a STOCK Stinger + jb4, apparently I can get in trouble by running too much E85. I.e. E30 should be ok, but > E40 can cause fuel pressure crash. Running straight E85 would be a problem, because not enough fuel, and so too lean, detonation, bad things..

If we install the FLEX fuel kit (no CPI), are all those same things still a problem? Or does the ethanol sensor in the FF kit let the jb4 read the E level and if there's too much E, jb4 just won't call for boost? I.e. is there a failsafe in the FF kit + jb4 hookup? Or could we still blow our engine? Does it change the size of the "danger zone" at all? I.e. now I would be ok up E50?

Now add in the CPI kit - it adds 85-100 HP of fueling capacity. That sounds like a bigger "safe zone" compared to just the FF kit? Am I understanding that correctly?

So what is the new danger zone with the full CPI kit (including FF sensor)? E60+?

Does just plain 91 already max out the stock turbos? That is, does the CPI do anything if we're just running plain old CA91? Or is it only a benefit when mixing E85?

Sorry to ask so many questions - just trying to understand what the tradeoffs are with this kit, and if I am interested in FF kit, or FF + CPI or neither.

[Terry @ BMS]

Will start adding directions and settings info to the first post!

With CPI fuel pressure crashing isn't an issue, but you will run in to fuel trims issues at idle/part throttle with too much E85. So for that reason on the factory flash currently E50 is as much as you should run even with CPI. This is more than enough to max out the factory turbos on boost.

[Avant]

Great product! Installed mine this week and Terry has been super helpful dialing it in. Currently Running E45 on Map 5 and the HPFP is running better than ever. Normally anything over E30 I would notice it would drop below 10 and sometimes crash but not anymore.

Install is pretty straight forward and doesn't take that long.

Powerband is a lot more linear and feels like it is making more power. Still playing around with some settings and fine tuning but the settings Terry posted in post #1 seem to be the best.

With gas so expensive, its nice to fill up half the tank with E85 at 1.99 a gallon

Thanks. So basically, up to E30 with just jb4, up to E50 with CPI? And with the sensor, the jb4 can adapt for whatever actual level of E is going in?

Sounds good to me..

I noticed in your photos, there is a hose going to the charge pip on the intercooler. I have a G70 as well and an agency power intercooler, I don’t have that adapter spot there, is there a different place to connect it to?

I have the BMS FMIC which comes with a bung already on the chargepipe. With your Agency power FMIC you would have to get one welded in.

[Steve @ BMS/Fuel-It!]

You could also drill and tap an 1/8" NPT bung yourself but of course take the appropriate precautions.

Does the BMS intercooler fit the G70 perfectly?

[Avant]

Does the BMS intercooler fit the G70 perfectly?

It fits perfectly. The only thing is the top brackets are made for a stinger. I just modified mine to work. Pretty easy and straight forward install.

What kind of modification did you have to do?

[Avant]

What kind of modification did you have to do?

The easiest way to do it is use exhaust hanger strap instead of the supplied brackets. that way you don't have to weld or anything.

To be honest, you don't even need them. Once the FMIC is installed its not going anywhere and doesn't move around.

[Terry @ BMS]

Keep those install photos rolling!

Ran out of E85 in the tank this morning. Just put straight 91 in and switched over to map 2. I will say that my Map 2 alone feels way stronger on 91 octane. Looking at my logs and they look very clean with not a lot of fluctuation in boost, timing and AFR. Very solid.

Are you saying CPI also helps with just plain 91?

[Terry @ BMS]

In theory you'll still get a little evaporative cooling effect on just 91.

[djerickd]

Any more user feedback?

[Imperial_Ghost]

Hello I am new here, I recently bought a 18 Stinger GT2 17k Miles. Of course I got it and immediately had to make some modifications.

I already have installed the BMS power package, BMS intercooler, muffler delete, and the EWG JB4 connectors.

I just received my CPI kit. My initial intentions were to run full e85, after reading some posts in this thread I now understand that I cant without some other things first.

Just to make sure before I can run full e85 I at least need a backend flash for my ecu.

Is there anything else I will need? I'm assuming I'll have to get some tuning done with Terry since there's no map in the JB4 for e85.

Please let me know what else I need to run e85.
Thanks

CPI install on Kia Stinger

Here are some helpful pictures on how to install the CPI on the Kia Stinger. I have it connected to a BMS intercooler, so the connection for the CPI was already there, other intercoolers you may have to drill into. I do not have the WMI kit yet so the orange cable is not connected to my JB4, if I did have it you would connect it to pin 3 on the JB4. The blue cable goes to pin 16 and white goes to pin 19. I also have the Fuel It flex fuel kit installed. If anyone has any questions or needs help with the install, please feel free to reach out with whatever questions.

[Terry @ BMS]

Not following you on the wiring as it should be per the first post. Maybe you noted the spots incorrectly?

FSB orange 3, blue 16, Fuel-IT white 4.

E50 is the upper limit for now, on the factory flash.

Yeah we caught that after looking around several times 🤦🏾*♀️

Assuming a "good" ECU flash, would that be enough to get to E85?

I've done a TMIC before, so I have some handle on doing FMIC, I think.

How much time did the CPI kit require for installation? Would it take more if Fuel It wasn't already installed? How much fuel spilled?

Honestly without the flex fuel kit it’s pretty straight forward. It took us about 30-45 minutes to install the CPI and mostly that was trying to see where to route everything. As far as spillage it wasn’t a lot but just remember to keep the keys away from the car and stow the hoses in up right position

[turboAWD]

Thanks. How much time does the Fuel It kit take?

As stated above. It is pretty straight forward. Fuel It takes 10 mins to install as its pretty much plug and play along with the rest of the CPI kit. The fuel line removal requires the proper took but if you have a hook pick you can slide it around while removing. Looks like below. It takes about 30 mins or so to install with removing the bumper and putting it back on.

[spicymami96]

Thanks. How much time does the Fuel It kit take?

That took me about 20-30 minutes to do. I installed that about 2-3 weeks ago

[turboAWD]

Thanks for all the replies. Definitely something I want to look into, if I keep the car (lease is up in a few weeks).

[spicymami96]

So I don’t know what’s going on but I filled up to e49/e50 and now I’m getting codes for bank 1 and 2 running lean

Check the logs - you might have had an HPFP pressure crash. At least, I know that's a common issue when pushing the limits of ethanol on the Stinger..

I’ll have to do some logs when I’m off of work tomorrow. I went through all the steps from post one to like triple check nothing was missed. I noticed I didn’t input the 1 for the meth and the user adjustments but I don’t think that should affect me. I did forget to do the 50 in all the fuel bias so that may have been the cause 🤷🏾*♀️ It was a long night when I was installing everything. Everything is correct now and I’ll be test driving it tomorrow

Probably fuel bias. I dropped mine down to 30 which seems to be best so far. Helped out with my fuel trims. Or too much ethanol.

Here is a 5th gear load run. E43. Car is running amazing and seems to have more in it with this setup.

So everything is set to the right settings and I’m still getting engine code lean. Should I increase my fuel bias

Can you clear the code and then try and get a log to post? Curious what your fuel trims are doing.

Yeah I can do one once I’m off of work. I’m just stumped right now because everything is hooked up correctly and everything

Also I never switched the map I was on originally I was on map 4 would that be an issue

[Avant]

A log will help us see whats going on. Clear the code and do a 3rd or 4th gear pull from low RPM to redline.

Post the CSV file for any advice!

Logs as requested

So here are the logs as requested. I did a couple of different ones on maps 4 and 5 with the standard settings as suggested in the first post and then adjusted the fuel bias to 60. Let me know what you guys think.
