Tuning With 160# High Impdence injectors

Tuning With 160# High Impdence injectors
After finally dialing in my tune with 80# Siemens injectors im switching to 160#. Stock PCM
Ive heard people having idling issues with a Boost Ref Regulator.
Im running a base fuel pressure of 58 and its ref to climb with boost. What does my Inj Flow rate vs. Kpa need to look like with the 160s? Anyone got a tune file I can look at?
Thanks

what data or other injector tables have you modified? do you have data? what type of injectors are they?
chances are your short pulse width and etc tables need to be adjusted to accommodate the new injectors. Set your fuel pressure BASE as 43.5psi and I believe that is what the 160# injectors are rated at , so then your IFR table depending on your UNITS should be 160#/hour or it should be in Grams/second I think
what car/computer is this on? could you post the tune file?

The tune is ALOT better but needs work its all around rich. im going to adjust the offset vs volts vs VAC table. as i have not even edited it since the 80# injectors.
Not sure what pulse width the injectors are idling at

here is where im at now. ive scaled the ve even more. the car idles around 12.2 AFR and cruises around 14. I can not lean the idle out NO MATTER what i do. Lowering values in the VE seem to do NOTHING
When i stab it, the car it goes right to 10.0
Any help?

the car is not trying to read off the maf. ive set it to disable throught the ses lights.
also the car is running pretty good my only issue is that the car stays pegged at 12.0-12.2 AFR idling, no matter what changes i make it still idles at 12.0-12.2. everything else is good driving around and WOT is good

you should be able to run those injectors down to a 1.3ms pulsewidth. can you get some information on those injectors?
if you get some information on those 160# injectors, are they siemens? are they bosch? what are they?
you should be able to get them to idle at near stoich at 43.5psi
