You're statement was strictly about the injectors.
My main statement about the injector duty/pulse is that low rpm you'll hit fuelcut very quickly, but there enough pulse width on the top end to run nearly maxed out on the injectors. As in, I've seen a few lexafm/550s setups nearing 500hp...
It doesn't matter how much the 440s support its how much the ecu will give before fuel cut. You're limited to the stock ecu.
But this makes me wonder, what kind of Duty cycle does the stock ecu run before fuel cut. It would seem as its not a static number through out the whole range, but it...
It depends on the setup. A stock injector rom and a upgraded turbo with upped boost will either hit fuel cut or go lean if the rom indeed doesn't have values above boost cut. It cant bypass the ECUs programming.
With a 550 rom with 550 injectors it changes everything, but I assume hes on a...
:rofl: seriously?
Ok this is what you do. Turn up the boost and hit the gas, watch the wideband and make sure it doesn't go lean, if it goes lean you lift off the gas, and add some fuel in the safc.
As for timing, ith the stock ecu, lexus afm/550s should be perfectly fine (unless you're...
A few months back I had a big exhaust manifold leak, I'm sure it caused some funky afrs for a bit. Other then that all is fine, gas mileage is normal. I usually fill up at the same gas stations and has been smelling for about a month and a half.
Though about 2 months ago I did fix my BOV so it...
Ok, so my car is bone stock (minus suspension and wheels.. oh and a sweet K&N drop in!!) meaning still has the stock catalytic converters and everything.
The car smells like shit now and assume the cats are going, is there any way to revive them? or at least stop the smell, haha. I know...
My car is from up north and had a leaky tank. IT wasn't rusted though, but the seam started leaking. Maybe it was just defective but probably the road salt had to do with it.
I just found a replacement and put it in (luckily i had my old 91 still sitting in the drive for parts, haha)
