Heck back in 1989 I was trained on the Dodge Monaco which was not like the old Monaco's as this used a foreign V-6 and it sprayed all injectots all the time everytime an injector fired they all fired. Mopar also did this before they went to ported and sequential injection. The 3.0 v-6 would fire half the injesctors all the time. Which 3 depended on which cyl was fireing. And before that they used throttle body injection as most were 2 barrels and would spray both injectors on every dist signal. Course didn't need a cam sensor on that setup. They finally went to sequential in the early to mid 90's. Mopar also used the 02 just for the fine tuning as the addaptive memory had a larger control over fuel mixture and then once in the right addaptive cell the 02 would fine tune it. Ron

I use to flow the throttle body injector(note singular)
back in the beginning of Chrysler injection.. I
built the first flow stand at Chrysler years ago
for testing injectors... I've flowed a FEW injectors
over the years

You mentioned different spray patterns, is there an injector that sprays at closer to a 90 degree angle,ie downstream, instead of the floor of the intake opposite of the injector?

---

None that I have heard of
EDIT
also in the way a injector is designed it would be
real are to get one to fire at 90*.. if you look at
it, its got a long needle and seat per say.. the needle
is called the pintle which is pulled upward by the
electro magnet when fired and if the fuel touches
anything it would puddle so you cant just put a 90*
on the end of the injector

---

I agree, it would be hard to get a functioning design to emit fuel properly at 90 deg, but if you could, would it be much of a plus?

Sure it would.. it would be directed at the valve
and it would already have velocity

I have found that my car likes injector phasing to fire at the back of the closed valve just before it opens, instead of firing as it opens.

It's a difference you can feel.

I am using off the shelf Mustang GT-500 injectors, @ $24 a piece. The spray pattern is setup for a dual valve design, but they work better than my old non-split injectors I had in it.

My duty cycle is 65% at WOT, on a car with 500 HP, and 542 Ft-Lbs.

---

Those injectors are probably split cone for the dual valve

the injectors edelbrock supplies have 4 spray nozzles, not sure it's any better or worse than others just interesting. Pretty sure they are magneti marelli. The cam sensor allows you to do individual cylinder mixture if your controller supports that with sequential....

With BS3 you can do individuals without a cam sensor.

I have no idea, but does the cam sensor only really matter and reference upon start up, or does it verify cyl #1? every time?

At about 5000 RPM it matters ZERO and very little at any speed. We used one until it took a crap and prevented our engine from starting. On the advice of a very knowledgeable heads up racing tuner we disconnected it. Engine started and idled fine. Threw the sensor in the trash. This is not direct injection. When the injector fires means little-especially as the RPM climbs. It all happens so fast it just doesn't matter.

My question was how you do individual cylinder tuning with no cam sensor.
As far as injection timing events.... No system is capable of spraying on an open intake at all rpms.

---

As I stated before with BS3 you can. It doesn't matter where the valve is when the event occurs. You just add or subtract fuel from the appropriate runner at any given RPM. Believe me...it works.

---

OK, so you have 8 injector channels. without a cam sensor you are still controlling the channel that is hard wired to the cylinder you want to change, but the injection event could happen at any point in the cycle. I get it now, but this must not work for ignition events. So I see how fuel trimming would work, you just loose individual ignition control.
