Has anybody done this to an N55 lately? Results? Have the tuning bugs been ironed out?

There have been a few, but it is pretty new. You would need to work with a tuner to get it working properly.

Fuel it just came out with a kit, there's a thread on n54tech

Yup, I have sent the N54 thread, and have visited the fuel-it website. I mainly want to hear from people here, and don't want my car to be a beta machine.

Do you need that extra fuel ceiling?

Good point Jeff. I want 500 hp without meth, or having to make logs every tankful. Maybe dialing it back a bit and getting the throttle body fueling will get me the power and reliability that I want.

Tbi should be sufficient for e50 mix and 500whp.

Anyone has this installed yet? Results, impressions?

Working on the installation next week. Will have dyno numbers etc.

[dannyle27]

what happens when you run a full 93 tank on long trips, commute, e85 station runs out, etc? effects? Gas mileage? Tuning for these lower octane?

Simple, you just run a full tank of 93. The secondary injectors are programmed to turn on at a certain group boost level. Therefore if no E85 and your taking a cruise run map 4 for stock boost.

If you're interested in making power gas mileage isn't a concern lol or we'd all be driving a Prius.

That might work if you have the 14psi hobbs, but obviously not if you have the 5psi.

I didnt think the PI kit triggers from a hobbs switch. But you could disable the split second by making a ground switch like I did with the hobbs tbi ground switch:

With TBI or meth it's best to tune conservative.

Equal distribution is an important factor when using either as fuel.

That's why I typically like to push Port injection for those that need the extra fueling capacity.

PI doesn't work off of Hobbs switch TBI does. PI is triggered by Tach and boost reference.

Yeah, wasn't thinking about the right system, but either way that is not going to work then. You will need to do some type of manual disable like Darkied stated.

You can follow progress in these two threads.

This is the source of some of my confusion of what to get. What is the point of getting the Platinum TBI if it is all on, or all off? As there is a mechanism for reading e85 content I'd think that would be eventually involved. For a future application? When? Otherwise it would seem senseless to go with anything higher than the silver kit.

I have the platinum tbi kit. It comes with ethanol sensor. You can read E% over bluetooth with mobile phone app.

Ideally with tbi you want to run E40-E60 and 20 psi or 20 psi+ of boost due to the on/off character.

As the e85 data is available, sorry if I really think it should be tied to a controlling mechanism that determines the content on the fly and make adjustments accordingly. Getting a reading on a cell phone and making adjustments accordingly sounds primitive in this day of digital controlling electronics. How well mixed is the e85 and 93 when people fill up anyhow? Yes, I am inferring that the proportion may change over time on the same tankfull. Someone up thread told me high amounts of 93 would cause miss fires due to an incorrect AFR. Fine, and understood. So this TBI kicks on at 100% at whatever RPM is set. Would that also not be a rich situation until higher RPMs are reached? Is there a plan to adapt the pwm device used for PI as a final solution for this? Sorry if I ask a lot of questions. I see two products with a lot of potential. One for ultimate power and control with Pure 2, and the other potentially providing enough for people like me. Unfortunately that one seems unfinished at this point.
