I just got these injectors in the mail today. After reading through the thread, I didn't see any posted latency/scaling values for 91 octane - anyone have some that I can use to get my close?
Thanks!

 

My fuel works out to the same as 91:

Scaling 943

4.69 = 5.448
7.03 = 3.648
9.38 = 2.352
11.72 = 1.656
14.06 = 1.296
16.41 = 0.960
18.68 = 0.888

 

Thanks! I'll use these as a starting point - I just wanted to get close! How are you trims?

 

They hover between +1 and -1

 

Thanks mrfred for the great write up as usual

Also thanks for gregm. I am using those values as a starting point, but am on CA91.

 

good bump. forgot to say, my tuner had no problem using these numbers as a starting point. these injectors truly idle and drive like stock. they are as loud as HELL, but only when you're standing outside the car. my car screams, now, it scares me.

 

bumping this so i dont lose it...my 1100's go in next week

 

What did you end up settling on? I imagine my crappy AZ91 fuel is not far off from your CA91. I plan to install these guys tomorrow night.

 

Started and ran, but no tuning yet. I just built the motor with new intake, valve job, and all kinds of details, so just getting it started was a big deal. I think I have an idle setting issue with the new TB so I only let it run for a fe seconds. just enough to know I have good oil pressure.

lots of things to work out though before I can drive to log and set trims. I'll post when I get to that.

 

I'm running 93 octane and these were my final numbers. They were spot on.

Scaling - 943

4.69 - 5.640
7.03 - 3.552
9.38 - 2.136
11.72 - 1.344
14.06 - 1.008
16.41 - 0.816
18.68 - 0.696

 

So I swapped out my injectors last night and installed these bad boys. I flashed these new values and idled. STFT is pegged at -25%... Wideband is reporting ~11.2 AFR at idle. What do I need to change? Scaling or latencies?

 

Increase Scaling

 

Your latencies at 14 volts are way too high.

Try the values that I posted above, my car used to do the same thing. I bet if you drive the car your mid trims will be much closer to 0 because the scaling is where it needs to be.

 

So I tried out your values this afternoon and those are working much better! My midterm is at -3.3% and the STFT is hovering right around 0. Much nicer! So far nothing has come up for my long term trims. Hopefully I can start tuning this week now since I got these injectors to support my new FP Green I installed!
Thanks again for your help!

 

Great write up! Thanks OP.
