streetTUNER inejctor scaling ?
just wondering if any one out there is running streetTUNER .
need some help with the fuel injector scaling .
running sti pinks w/ vf-34 .
manual reads : for sti pinks start w/ a value of 5120 .
with engine idling open dashboard & display A/F learned & A/F correction .
but dashboard doesn't have anything labeled A/F correction only has
A/F trim learned & A/F trim immediate .
any thoughts ?

Delkwon,
I'll give you what I can, but my background is UTEC and DeltaDash.
Scaling is designed to 'baseline' how much override the EM must factor in to all of it's correction. It's sort of like a multiplier applied across the map.
For instance, the UTEC scaling interface asks you to input what you 'think' your injectors are designed for. For instance, STi pinks should be able to handle injecting up to 565cc's (per minute, I believe.) So you know to input 565 (or 5120 in your case. Different value but same outcome.) However, your injectors may actually 'stay open' a millisecond longer than another set of 565 pinks. Therefore the need for fine tuning.
As to A/F learning and A/F correction, that goes to how the logging software graphs what the sensors see (input into the map) and what the ECU, based off of the learning, tells your injectors to do.
My guess is that A/F trim immediate equates to correction.

here dude... here is the vf34 map for the 02-03 WRX in streettuner version
http://www.cobbtuning.com/wrx/street...f34%20v130.stb
VF34 map originally designed for 91 octane fuel. Requires VF34 turbo, STI injectors, stock intake, stock intercooler and turboback exhaust.
that's a base map by the way
