Vit's FI TT 370Z Lives!

That is great work with one bad axx ECU.

Cranked it up a bit yesterday, the boost by gear doing work!

I think with proper tuning 14psi or so isn't out of the picture on 92-93 octane fuel. This should be about ~600whp or so on pump gas.

Couldn't do it before due to the clipping point of the stock mafs.

Fun little gimmick that I programmed in the ECU -- power estimate based on accelerate rate (of non driven tire, so no wheel sleep problems here). Obviously instantaneous accel is kind of "jittery", so you can factor it to "smooth" it, I'm using too much in this example, and it got a smoothed graph that looks nice, but very very low ball values compared to instant, hah.

And here you have it folks, worked out the fuel pump (fixed itself?) and replaced the cam sensor. Making some great power on good ol' 92 octane fuel.

Cruising down the highway with no vacuum in the manifold at all, no problem.

Great still getting 22-26mpg depending on weather (was getting 22mpg in the rain with a head wind, not bad at all lol).

Welcome to true flex fuel logic. No analog converters here -- we run the content sensor directly as the digital signal it is, to not only get flex content, but fuel temp from it as well. Going to need a fuel system upgrade from @phunk soon I'm sure, as my fuel system is pretty tapped out as it is, lol.

I like that.. sucks having to buy an E85 content gauge kit just to get an output to use with the ECUTEK.

In the past I would just use the analog converter boxes without the gauges. I HATE gauges, I feel like they clutter up the car and are absolutely useless (boost/afr/content, etc -- who can really watch them when you're hauling ***?)

The stock ecu has a lot of limitations... 10hz output for boost control? eeww, so bad, lol. And the amount of inputs for extra stuff is extremely limited too.

Listen to that chop lol

That's cam ghosting?

Been running 30-35% ethanol content. Car feels great and still gets ~22mpg on this blend while allowing me to make a bit more power. So much fun. Hopefully the crappy whether here clears up and I can get a rolling anti-lag and launch control video done.

Launch control & rolling anti-lag in freezing temps. Once it warms back up should be able to get this thing to roll out hard from a dig, even on RE-11's!

What were you stealing the oil temp gauge to display?

Right now my programming allows you to steal it to display:

- Boost
- AFR
- Knock Learn % (custom strategy)

You can change what it displays by just pushing one of the cruise buttons.

In the video it was showing boost, half way up is 8psi.
