BLUF: I need to get my observed Min Inj PW lower. FIC lists it as 0.45ms but I can only get down to 1.7ms.
After I installed the FIC (clinic) 525cc injectors I've been having issues with hitting a Min Inj PW wall. About 1.7ms.
My issue is that when in the high vacuum areas of the VE/lower RPM range, IE 15,20&25kPa, I am not able to pull enough fuel out. The Min Inj PW will not drop below 1.7ms. This is causing my STFT to pull a lot of fuel in the neighborhood of 10-14%. At higher RPM this isn't an issue as the 1.7ms is fine. Around 2200RPM and below in OL the car goes VERY rich. The result of the STFT going negative is a get a huge dead spot in power on tip-in. The car goes VERY lean. >20 according to my WB.
Obviously going OL I do not have the STFT issues causing a loss of power on tip-in but that's a fix of the symptom and not the cause. I'd prefer to not run really rich at every tip-out. As a note, lowering Transient Fuel mg brought my Min Inj PW down to 1.7 from 2.2ms. Any further changes to TFmg only add instability to transient situations and doesn't lower MIpw.
Any help you can offer is appreciated.
Is there a better way to provide the scanner setup outside three separate files?
