I'm using it, though with a modest tune. If you want data let me know what.

Everything seems fine in logs, and no obvious problems otherwise. I went from about 36% E85 to about 58% E85 after install (E30 to E50 when E85 fuel is actually 85% E). FBO except stock turboback exhaust system. Went from 13psi with timing drops in high ambient temp multigear pulls, to, so far, 14.5 psi with no multigear drops. 15 psi saw post-shift drops when tuning in August I think, so I turned it down a little and it was fine. Install was a pain for me, including the add'l fuel pump and controller, but I only work on cars now and then. If connecting under the firewall the CPI install itself is pretty simple without snags, as I talked about earlier in this thread.

Based on my experience and general knowledge, I recommend it if you want to trade long-term expense and effort for short-term expense and effort, AND E85 is easy to find. I.e. it's a more carefree alternative to water/meth injection, but more complicated to install.

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.

There is a local e92 running cpi, fuel it s2 fuel pump, fbo with hexon turbos. Running full e85. Tuned by wedge. Only issue is afr banks on 1 and 2 is not the same, but looking at the logs there seems to be no issues

I'm interested in ditching my TBI for this in the upcoming months, but I have a few questions hopefully someone can answer. Will I need to do any tuning changes to AFR bias if using this to run full e85 on the stock turbo n55? Or does that only apply to running map 6? Would I only need to adust my FOL if running map 1,2,5,7 or is there more I need to do that's in the BEF? And do I still need the BMS PI controller or is there something in the works from fuel it?

Can we just use posi taps and connect to the purple and green wire directly without the use of a pi harness

If you have the connectors for the injectors, that shouldn't be a problem.
I wouldn't advise that though lol.

It would still need to get posi connected to the harness as the cpi end doesn't have a plug.

Did you custom make the harness? Usually our harnesses come PNP with the female connector on the controller and the male connector on the harness.

I connected it and see it working. Fuel enchr kicks in after 3k,and hpfp doesn't dip under 13 at 21psi

But the kit was bought from a local who sold his car, and he used it this way without issues

Sounds good! If it's working I can't complain
