So my car is finally put back together and I've been able to turn the engine over, it rumbles, farts, pisses, then stalls. I'm attempting to adjust for the 60lb injectors but wanted to ask if anyone had pointers before I go into it. I've done some searching but haven't turned anything up that really helps.

 

If your talking about the pencil type 60s, they use a fairly long PW at low RPM. as in they weren't too much different the with my 40s. But, as the times get of over 3msec they start moving alot of fuel.
YMMV

 

What brand injectors? What is the BPWs when you first start the car and it runs rough? Are you running single fire or double fire batch mode?

With the Ford 42#/hr saturated and Siemens 55#/hr P&H I had to play around with them on the bench to see how they flowed.

What was the brand & part number on those 60s? As you described, those injectors are very nonlinear. Must have had a strange looking VE table to get the fuel right. How steep was the under_3ms to over_3ms transition? With a steep curve it will yield unpredictable BPWs (much like the NBO2 problem).
I am curious on the brand and part number because I would like to stay away from injectors like that if they are very non-linear in certain regions that can't reliably be corrected for. Did you fix up the problem with the VE table or another "non-linear BPW correction" table?

 

Grumpy, thanks for the info.

Junk, I bought them from Lingenfelter: "Siemens 60 lb fuel injector" Flow: 6.9-10.7 g/s @ 250-600 kPa
Impedance:12.5 Ohm

I haven't been able to get it to even idle yet (only have worked on it for about 3 hours.)

 

On something new, I tend to move the inj. constant/ BPC around just to get it idling. Then once I have an idea of the running MAP, and PW, start working on things with the correct BPC/IC, and changing the VE to match. Having an ecm bench makes quick work of things once you get the motor to idle.

3 hours... sounds like it's fighting you, the changes you're making aren't big enough, or you technic needs improving. I say this as inspiration, not knocking you.

 

I tend to hone in the BPW using a different approach. This may or may not work for you.

1) calculate the proper BPC for your engine and injectors
2) reduce the 1200 RPM and lower VE values by 30% for the %58 code
3) reduce the crank BPW (AFR) by 10% for the %58 code
4) connect up the ALDL link
5) hit the record to file
6) look at the recorded BPWs (and WBO2 AFR if available)

Using that method it took about 5 minutes to get my second $58 install running on a new engine, new injectors.

If what Grumpy says about the 60#/hr having large BPWs at idle and cruise is true then you should by fine. If it is BS, then you will have sub-millisecond BPWs and the stock qausi-fueling is going to give you a challenge and the 60#/hr most likely will not work. I hope what he said is true, but "fairly long" can mean many things depending on the cam, EFI system, etc.

 

And how much time do you have with 60's?.
It's laughable just how much opinion someone can spew in one reply, but thanks for the laughs.

 

None. If what you are saying about the under 3ms spray pattern varying from the over 3ms spray pattern is true then it must be that they take a long time to open fully. That would mean that the are very picky about getting clogged because they are running never fully open at idle and part throttle cruise. Again, I never claimed to know anything about them I was asking what part number 60s did this. You must have missed that part.
Is that 3ms including opening and closing time? What you wrote was very unclear.

Where was the opinion? I think you may have mis-read the questions. You're welcome.

 

Since you don't have any experience with them, then all you have to work with is opinions.

You can find your own parts numbers, I'm not going to waste my time, for your curiosities.

Again, thanks for the laughs.
