All that fuel saturation that area, are you 100% that there is no pooling,or concerns of vapors being back drafted thru the turbos into the hot exhaust?. I'm sure this is a far fetched sanario, but seeing that your using an actual injector, there is a tremendous amount of fuel being pushed thru instead of a nozzle.

No issues if you follow directions. You'd be surprised at how much a meth nozzle can actually flow.

I have it on, the car runs (no flames coming out), and there's activity in Fuel_En in a log. That's all so far; if someone with PI experience wants to tell me what to do and what to look for to check function, that might speed things up with useful logs. Or I'll just wing it.

PSA, if you plan to tap into the fuel line under the firewall, 24" probably won't make it to the CP meth bung. I found out the hard way and had to wait a while for an extension.

Log is with Fuel Bias at 10, 4000+ rpm.

Awesome, thanks for responding. Did you order the "starter kit" (minus the extension you needed)? Please keep us updated on the tuning side of things. How easy was the DIY? tapping into HPFP etc.

Yeah, starter kit, with 950cc, the proprietary line splitter, and an additional 90 degree elbow to run the new line parallel. I went under the car instead of under the manifold, so didn't touch HP lines. If everything goes according to plan that's pretty simple as long as you have extensions and universal joints for a ratchet, but I almost gave up trying to get the stock line disconnected. Just wouldn't budge, then it did.

I installed it with the BMS PIC, and FI-650HP pump. To be honest it was all a complete PITA for me, lol, but if you work on cars a lot I don't think it'll be harder than usual.

Okay cool, yea I suppose I could figure it out but it sounds like I'd get frustrated LOL. I'm not sure they put out a "how to" or anything.

That's how I felt, so I asked them a few questions first until I felt like I could probably make it work. Then I looked at as many parts diagrams and barely related DIY vids I could find. For my car it may just be one panel, the big one under the driver's seat, and then the guard for the line and some other lines as they ramp up under the firewall. I started with a small panel by the wheelwell that might not have needed to come off, but it's possible.

I wouldn't go less than 30" if tapping in there, by the way. Depends on your charge pipe I imagine, but ER (which I have) and BMS look similar.

Got any pictures to help people for future reference?

Not of the install, I had my hands full enough, but I could take some top down shots of the CP, injector, and line.

[hi rpm]

At 12:43 here he's taking off the line "guard" under firewall. Panel already removed. Front of car to right.

Here are some pictures. This is with a 24" line, a coupler, and an 8" line, which was plenty, so I made a vertical S shape.

Injector: https://i.imgur.com/WZ8QP1i.jpg

Line ziptied to apparent vacuum tube (just snug enough to prevent movement): https://i.imgur.com/EboDZwP.jpg

Far end of line goes into guard by firewall, next to other fuel line: https://i.imgur.com/tBNyBBF.jpg

Second log is attached with Fuel Bias at 5, 10, 15, 20, 22, 24, 26, 28, 30. It seems like timing and IAT is better, but I'm not 100% sure it's working yet. I read to set Meth Flow Scaling at 99, but it just goes from 0 to 100 in the log. Maybe it's different for N55? I think I'll turn up the fuel more tomorrow and start a tuning thread.

[Marlinman]

thanks so much, look forward to seeing how it works when you get the tuning configured.

You bring up a good point, maybe BMS of steve can comment on initial settings in the JB4/controller that one can start with and under different circumstances for flashes (stock vs BEF).

So that HPFP adapter they created allows you to T into the LPFP line and connect the injector line? I.e. nothing is replaced on the stock system (aside from LPFP) just added to?

That's right. Even the FI-650HP is just an add-on actually.

[Marlinman]

for a cool 1K LOL, thanks for the help man

Hey Payam, Where did you run the RPM switch for PI on the F10/90? The S55 manual says it goes Pin 3 on the ODBII 4 pin but on the F10 OBDII Female side that is a null opening.

[mojo20032004]

Alot of good info on cpi and n54 coming soon..stay tuned ������

The OBD cable itself or the Jb4 harness? The OBD cable should have a female spot for that pin, more than likely will have to send you a male pin to insert into your existing harness to connect to the PI controller.

Thanks for the clarification, good to know it will work.

.

Is this going to be impossible to successfully run with Meth just like The fuel-it Port injection and bms controller ?

Pressure switch/ flow sensors available in a near future ?

So here is the problem, that connector is NULL (Would be the lower pin on the right). I am not sure how you would get RPM sense out of it since no wire runs to the OBDII

[Payam @ BMS]

Ahh, you have old OBD connector too. Let me see what I can do for you.

Payam,

If I was to go about installing this myself, how would I receive tuning support? Meaning can I keep the MHD BEF I have now and play with the JB4 settings as far as boost control and controller? Or do I need to wait for some BEF support specifically for this? Would you all be able to provide tuning support?

Yup that's exactly what you do. You will need the JB4 PI controller with this and we will help you dial it in. Post up the logs once you get it working and I can help you. You can also email me as well

[Marlinman]

Has anyone tried running this CPI with a stock LPFP on a 335? With other options out there including the replacement HPFP with higher flow, the manufacturer claims the stock LPFP can support a little over 500 with that setup, curious if anyone has tested the limits of the stock with the CPI.
