You can remain stock and up the injector fuel pressure is a cheap loophole. Say the std fuel pressure is 43-45lbs.? You can bump the fuel pressure up to 100psi no prob is make sure there are no fuel rails that are made of the plastic (style) is the o-ring may pop out or fail as the plastic pops out of the assembled sealed connection (at the o-ring) or the plastic rail cracks/splits at the weakest link.
Right there is a save of all that money/work is bump the fuel injector pressure via watch the and lock the rail pressure via the fuel pump relief valve is to mash the spring down is crush the relief valve housing is one way to loophole the stock pump assembly.
As far as the crank sensor, is not 360 degrees 360 degrees? You may have that tone wheel on the crank is a signal either ECMight recognize?
I would 'first try the 3V's' to make the late ECM light off the early telemetry. All you need are the 3 variables (ask 99 for the 3V's) is see if that lights off the fuel rail is that injector signal on the crank throw and if say she shoots 38deg full advance or say 36degs on the old ECM (for argument sake), you can piggy the advance curve (manually/electrically) to max hack is let it ride in that fixed advance setting. Meaning, in a less advanced set is the safety hack.
As far as open/closed loop, your racing wire harness is just 3 (main) wires off the ECM is (now) open loop; (so as not to write a book making harness if you knew the telemetry engine killers).
Now if say the fuel reversion is too much fuel and you could use a lean-out process is to drill a (testing to find the right numbered hole size), in each exhaust header; say out about 4'' from the header pipe.
You suck in cold air is the reversion is less fuel is you are way too much rail pressure is that rich set (not even a piggy on the electrics, (yet). Just the mechanical pressure heading in faster is same cut signal only a touch fat. No electrical injector cut needed, (or maybe). Who knows?
This drill mod acts more the lean signal is what all the other 02 (telemetry) is setup to do; is add fresh air so the gas can keep burning before the cat honeycomb.
As far as the clock speed of the ECM's is that faster analog process; is who cares! You still fire off at the required advance mark is 360 degrees. Not too concerned if you feel an electronic signal as opposed to a digital signal being faster say (from year to the next is now 3-D maps= WOT next?). It's just a drive-ability smoothing thing; is you are not too concerned about how it lights off is use a plasma ignition off an airplane application say if you want a hot spark.
Why invest all that money when you can update a car on a trade-in or you know.... Cost exceeds a new ride is update the who car why don'tcha. WE are getting a little bit into the R&D of tee lem eee tree.
Lots of trees of diagnosing it out is all that time and money testing. It now becomes way too complicated you chasing a faster running circuit board in the black box.
Why not just an exhaust/an intake change; rebuild the ball joints in the front end and align the wheels like a F1 car is go find some Lambo's.
So, WOT are we up to is, 99's tune and my tuning approach? He's got you changing out the tone wheel off the crank it 360. I got you with a 3wire deal (without going complex to explain is way too basic simple the way) out of a used ECM with a few wires out of that black box. A fuel rail change of pressure, (sans the muff-a/c change) are 3 changes.
You add that ECU in the mix i$ getting expen$ive now.
Remember is that 360 is gonna fire at the correct degree is equal speeds say both fire on that degree if you side by side both (engines) light off at said degree = 360. The late box is telemetry is faster is a smooth analog feel to the gas pedal is all. Same degree fired, just feels a touch smoother feel.
Call me, Re-luck-tore free.
< Same degree'd fired. Way more fuel than I need is the rail pressure and or piggy to cut the injector time long/short = Rich/Lean. Ragged digital degree now is harsh and I mean a harsh ride is the hack away from 02 (is eliminated now). We are now at the 1Atmo fire in the complex say.
If you knew your 12Varialble'basics, you would not be so confused is 9 can get you there too. Or, maybe not. Keep reading diss is so complex is way too simple to explain the shop manual abstract code pages. Is wear out your brain eye get the info from is in the absolute way the car fires off.
< Looking atchew
YOu are getting closer than you think a dink are easy steps to the; think it out what you are touching and WOT not to touch. Eye sea way too many parts being swapped for nothing.
