Yeah I'm thinking that this issue lays elsewhere then with the injectors although I will say they are the loudest injectors I have ever heard and I used the FIC bypass, not a homemade or eBay bypass. The scaling on 93 is 975 for me and I have the latencies dialed in where my STFT hovers around 1-2 % plus or minus and LTFT is 0.80 so that's pretty darn good I would say.

For the 90550001 ROM, replace "31db" with "3977".

Has anyone contacted Injector Dynamics for the flow rate data breakdown on the popular used sizes of 1000, 1300 and 2000? If not i'll flick them an email.
I'm keen to make up these correction tables for the 1300's particularly as I believe they aren't quite perfect down low now that I have used a few sets.
Cheers.

Boom, thanks!
I just messaged Paul, hopefully he'll get back to me!

Thank you Merlin! Will try these out tomorrow morning.

Changing the linearization values will require a substantial change in the latency value. For merlin's values, I suggest starting by lowering all the latency values by 0.05 ms. With no change in latency, the long term fuel trims will go more negative, especially idle.

Utilizing Merlin's ID2000 values, Idle on built head and GSC S3s. Target Idle RPM is 1100
Believe it still has some room for improvement, but it doesn't swing near as often as it used to. This is also using the Wideband o2 control patch with no narrowband hooked up.
