can turbo fuel injectors go on a n/a motor and work with the stock computer

if you adjust your maf probably, but why not just have the OE ones cleaned?

WadeMCarter

yeah it can work, but i highly doubt that you will have the need to do the swap.

my car has a custom short ram intake i made a cold air box to go wit and i have a header and a straight through exhaust i was i thought that maybe just slap on some bigger secoundary fuel injectors and maybe a high flow fuel pump in case i needed the extra fuel

You won't need them.

Say what?

All N/A rotaries run rich any way. You shouldn't have to add any more fuel to the motor. You probably just need to tune what you already have.

phoenix7

you don't need them. Your mods are so insignificant that you'll just be hurting your car, wasting gas, wasting money , and killing those driving behind you with the fumes.

Street knight: please explain to me this ADAPTIVE fuel system that will take a much larger injector (as in IT FLOWS MORE THAN STOCK) and ADJUST it without any other fuel controler besides the stock computer.



so, a 550cc injector will eventually flow 460cc's????? HOW? Please show me which page on the FSM shows this ADAPTIVE fuel system and how it is able to compensate for a much larger injector and then automatically lower the flow rate.

There's no way in hell you should be running anything larger than a 460cc injector in a mildly modified N/A model. You could actually reduce the size of your injectors slightly if they were available in the proper configuration. Invest that money you're gonna waste on injectors, into a fuel controller, such as an SAFC2. Then invest the money you'll have wasted on gas for 6 months, and get a wideband.

SAFC+wideband= win

I do believe you can tune the NA to 14.7:1 for best fuel economy but I've never tried it. Any input on this from anyone else?

iceblue

14.7 is a bit lean

phoenix7

it is super lean! I would never even say 14.7:1 with a turbo, but the NA won't spike, and if you're cruising to and from work you really could get away with really leaning out the NA. I wanted to get some input from others that might SEE something I'm just not seeing.

There is no such thing on FC's. The system is over 20yo...

Yea the adaptives came out around late 90s. My 99 intrepid has the adaptive memory, just depends on the system, which basically it learns when your throttle stays open longer and just performance things.

NZ, I take the time to set up a very nice Pwneage post and you absulutely, without a doubt pulled the chair from under me. sigh.

14,7:1 is okay for idle and light throttle.

Also, N/A do not have boost spikes, but if you mess with the CAS, Maybe your engine will ping at high RPMs ( I'm not super sure on this one. NZ??? ). So the WOT map should be a bit more rich. Just to be on the safe side.

No pre-renesis rotary engine will idle at 14.7:1

TII '87

Damn!!! I swear I read that on this forum somwehere... sorry

what's the ideal AFR for idle and light throttle then?

sorry

iceblue

12.7 13.1 ish

phoenix7

^^^ but remember his AFRs might not work for your car, even with similar mods. That's like assuming HIS cholesterol meds are going to help you as much as they help him. A while down the road your liver shuts down and you're dead.

umm no not really

Or like saying his park bench spoiler won't create the same amount of down force as your park bench spoiler, because the two benches came from different parks.

there is an adaptive fuel system.. closed loop!
