not true

just cause u tune the AFRs doesnt mean u get better fuel economy.. ur engine is working overtime, more revs, resulting in quicker injecting of smaller mixures of fuel..

Yes it is. If everything is exactly the same, you drive for x period of time at y revs with 10:1 ratios you will use a certain amount of fuel. You do exactly the same thing with 12:1 ratio and you will make more power AND use less fuel. What do you mean the engine is working overtime? more revs? Im talking about the same scenario where your driving style doesn't change.

Of course you are getting worse fuel economy if you have a bigger turbo, a bigger turbo means more air and more air means more fuel. Use some logic next time you reply.

I hope my post was read properly, the main reason I would look at the NEO is because of the fact that PFC has gone End of Life and in 6 months will not be $1000/unit..

Also tuning costs more for the PFC as it takes longer especially from scratch.

Personally, I don't need a PFC.. I don't have different injectors or turbo and am not chasing the dragon trying to get high power.. I'm just after getting my car out of <10:1 AFR which is what the SAFC will be able to do at a reasonable price + tuning..

THAN maybe i'll change over to the PFC or a different fully programmable ECU.

So has anyone used the NEO, I believe it now has 16 points rather than 12 which should help..

Remember when you tell your ECU its at a different part of the fuel map, its also going to think its at a different part of the ignition map, so you'll be grabbing a little more advance than before.

More advance as you get less fuel... just gotta be real careful not to go for too much to quick.

I'm probably going to get an SAFC even tho i'm one to say initially NO go. But if you grab one at under 300 second hand, its worth it just as a fuel saver and a little smoother driving... i don't intend to make my car a street racer.

When i get keen for any performance at all, or even more boost, i will want ignition timing control also, so full ecu.

I see it as either the cheap option ( like only using FPR's and base timing ) , or the "my car is all but stock, just giving it a little tidy up" option.

how to adjust and lean out the safc??? i want to know and adjust mine...i think my fuel is to rich...

Take it to a tuner and get it done on the dyno, its not safe to do it yourself even unless you have a wideband O2 sensor, even then you have to be careful.
