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

:) cheers :yes:

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.

:sweat: cheers :(

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.

    • While there is no current law for the spoon, let's swap to a different utensil. Example, does the store get fined for selling a butter knife if it ends up being a murder weapon? Perhaps they cpuld be done for assisting if they *knew* it was going to be for such a purpose. But, if used properly, which was its primary design, it's a tool for a job that's legal. I could understand companies being prosecuted if they advertise their products for being road legal if they in fact, are not. Possibly, but not necessarily, the tuners for tuning a car to a non legal fashion(emissions), but there is always the possibility that the customer really doesn't intend to use the car, in that configuration, on the road. So long as the companies can prove they have conveyed how illegal it is to use the now illegal car, in a place where the vehicle must meet the laws, they shouldn't be punished. Not sure about other countries or states, but I've been made aware that I can't legally stop a client from taking and driving their own car in NSW, Australia, even if they owe the shop money. It must go through court to get the funds from the customer, and you need to get the police or roads covering body representatives to come and stop the owner from driving the car, even if I know how hazardous the vehicle is.
    • probably around the $1700-1800 fitted in his sizes.  The ar1 is heaps cheaper. Get on scumplace I got some A052 295/35/18 for $400 that had done maybe 20-25 hot laps of SMP. 
    • People are going faster on CRS than AR1, so there's that 😕
    • Go the CRS, cheaper than the A052 and same if not better 1 lap performance when suspension is dialled for it. If wanting to do back to back laps the A052 and can cool off and go again next lap will be the better option. I have gone quicker over 1 lap with CRS than the A050 I came from but may be due to getting more seat time. I am driving CRS on the street lately in different conditions and its going well, a lot better than AR1 in the wet. AR1 is a race tyre, CRS is a Hill Climb/time attack/Sprint tyre. 2 different things, a slick is on the way too. The mighty gay mods choice of tyre is proper rubbish for those that actually drive on track not park at bunnings at night.
    • Seems to be a common issue, I had a look at two used tanks and both had similar cracks to mine. No one that does plastic welding near me seems to want to do it to a fuel tank lol
