i had zero problems with my built motor and id1k's.

then again, i was the test car for the rest of the population for these things. if the o-ring on the base of the injector, {on the stainless part} is too small, you will have an issue.

 

I ran the id1k's for over a year on some hacked up scalings I made based on the 79# scaling last year (Area you might remember pointing me in the right direction in a PM 2 winters ago.) It wasnt until I used the scalings from Paul Yaw that I had the idle issues. I could switch back to my old maps and the car would idle like a dream, then switch back to the new and it would pull timing and idle up. The car certainly ran MUCH better on Pauls scalings, but the idle annoyed me. Figured out that setting the TB scaler to 4000 or above cured the overspeed. Not 3999, but right at 4000 it disabled it it seemed. Car ran smooth, I added timing to coastdown, changed DFCO settings, called it good enough lol Im lazy

 

thats what i thought also but a friend suggested a boost leak test and when i did that. that is when i found my leaks

 

Are you running a BRFPS or RSFS?

 

Oring issue is fine on the injectors. I even doubled the orings on the base so it wasn't an issue. It's just tuning them to idle right now. The car wont cut off but on an abrupt stop idle will hunt a bit before she smooths out again. Joe has found some insight into tuning our dumb ass computer with tables we cannot use or arent there. That's why everyone is resorting to the scaler for idle. Shell idle perfect when done.

 

Nope no need so far my stock 07 pump is keeping up just fine on e and the 1000s

Although my aem wideband decided to freeze on me yesterday and I just replaced the dam sensor 6 months ago

 

We found some insight to the scaler and ill give u a hint, its not raising it

U also weren't running cams at that point either

 

Well help please lol

Every other gm pcm has integral AND derivative idle controls which would be amazing for us.

I've ran my scalar clear up to 6500 before with hardly any difference.

 

Well my question had nothing to do with providing enough fueling at WOT. But since you know everything I will just keep my suggestions to myself.

Meanwhile, I can get my 80s to idle like this.

80s Idle - YouTube

And 98# injectors are supposed to idle so much better then 80s...

 

My 80s idled like butter as well. A lot has changed in my setup not just the idc 1000s. Not claiming to no it all just think its funny everyone believes they need a brfs or a return setup that is not the case. If i were an 05 with a weaker pump I'd be worried but im not

 

An they are supposed to be easier to get to idle due to the pulse width flooring not the injectors themselves. My issue is now even at idle my car is flowing much more cfms than the old setup. We need to tune for that but considering ee dont have advanced computers with more tables available well have ti tune around it with what limited tables we can change

 

My point is...it would be easier to get them to idle better by lowering your FP at idle. It has nothing to do with the year of your pump and how much fuel it can supply.

I think its funny how everyone is rushing to 98# injectors when they are not necessary. You should got a RSFS and kept your 80s.

But I know it sounds cool to have injectors measured in CCs since the past 8 years this platform has been using pounds like a bunch of dopes.

 

We've also considered doing that as well. If we can't get them to idle the way they should, then ill go that route. Only reason i really went with the 1000s is i got a killer deal on them. And on my old setup with meth my idc was already pretty high

 

I went with the 1000's because i know i had big plans, and there were ppl maxing out the 80's already.
Yes you could just keep cranking up the pressure, but that would negate the benefit of low pressure at idle.
Plus, injectors can only operate correctly up to a certain pressure. Not sure what that limit is on the 80's but id's can take up to lmost 100 iirc.

Having a base at 43ish and dropping lower in vac helps the
Idle, and at that base i hit idc's in the low 80's on a cool day.

 

my issue isnt a fueling issue anyways. The 1000s will be fine. Bryan never ran a brfs or any of that either there are ways to get around it.
and by the time i bought that other stuff it was cheaper for the injectors anyways

 

Good point about the negating the benefits of low preasure at idle.

But it should be noted that on ZZP first 2.3L stroker where they made 357whp? they were running 60# injectors with FP around 75psi at WOT. So displacement aside, power can be made by cranking up the FP.

Bryan as in Area47?

 

You setting your scaler to zero? Is that what youre getting at? Or are you changing the displacement tab maybe?

 

we were comparing some logs of the old setup and new. My new setup is flowing alot more at idle, and for some reason the throttle body plate isnt staying in the closed position so were gonna try a few things to correct it

 

i had the gm blue printed cams. not 100% stock. just close enough for scca.



i ran the 98's before i did the fuel system. it's not like i can't get a cammed 98lb inj car to idle and act fine. i have been down that road before.

increasing the scaler is not the answer. since hpt doesn't want to give you more lsj tables. or the much needed one like the base idle airflow tables. you wouldn't be having this massive problem with big injectors, or cams.

just an fyi. you will be out of pump here very very shortly.

 

Is that the reason that you just less than halved the cylinder volume sir?

 

the cams you ran were stock the blue printed aspect of it just ensures that they were of stock lift and duration

 

I'm not saying u didnt get her to idle i know u did. You're one of the few that actually tunes the car. We will get mine to idle right now I had some other issues POP up. Wideband is stuck on stoich and I have to fix that first. The reason i said u werent on a brfs or a return setup is because I remember u running them first without that. The car is also on a pure maf only tune so I could seat the rings in.

 

My idle issue is with the cams themselves, not the fuel injectors. If i were on stock cams it wouldn't be an issue. The cams just changed things around a bit and the lack of the tables to correct it is the issue

 

raise idle

problem fixed

 

Lolz
