R32 Gtr Single Gt35r. Apexi's De-jetro A Good Choice?

But we arn't talking about 1400rpm in 5th? We are talking about normal driving conditions; keeping up with traffic which may mean 0psi-2psi of boost.

Tune these area's to as lean as they can go (sure reduce a little response but who cares) and you WILL pick up fuel economy. Why tune light/part throttle for maximum throttle response.

Not arguing discussing.

I think I have simply missunderstood your line of thought or missed a prior post or something

The PFC's closed loop is closed loop, being 14.7:1, you cannot make it run leaner even if you wanted to. Tweaking of the inj. map is really all you can do, this attempts to bring afr's closer to the closed loops target afr.

Datalogit

Settings 1

"O2 Feedback"

Default is 1.047 lambda ie; 15.3 A/F ratio = around 1 volt on the lambda sensor output

Change it to whatever you like as long as the narrow and slow lambda sensor can read it

Tip, lean it out at pre boost rpm (load) and use the acceleration enrichment to get the throttle response

Im lucky because i can flick a switch and have a totally different Map for max performance or economy,Changes on the fly instantly.

I reckon you have 2 maps, one for "max performance" and one for "poorer performance". The fuel ecomony shouldn't change if the car is driven the same. Efficient combustion for power, is efficient combustion for fuel ecomomy.

Placebo effect, you flick the switch on the ECU for fuel economy and the brain gets switched at the same time. Hence better fuel economy.

The best fuel economy switch is the one under your right foot.

PS; yes I have tested it, I set up a car some years ago with an economy/power switch (that did nothing). After a month of testing (the owner thought the switch leaned out the mixtures), bingo the economy position used 12% less fuel. You should have seen his face when I showed him an unconnected switch.

My normal setting is U98 fuel and the second Map is NOS and VP109.
