Injectors scaling

[boostcrazy]

stock sti's injectors scaled @ 552.47 & stock wrx @ 420.23 (both 2L Euro models)
question is how much can i scale a wrx with sti's pinks? I know that 500cc is a recomended safe number (~90%) but what's the concern of scalin a wrx as per sti's(552.47)

I'll be interested in the answer to this also. Would have though you should scale them the same as the STi unless someone knows the software interprets them different (expect not). If you don't, sharing maps with people would be a PITA.

There's no conversion to exactly match the published flow rates of all injectors. The idea is to get you as close as possible and then on your particular car and combination of mods, you can fine tune it by logging your A/F correction and A/F learning and making changes. No one who upgrades injectors should just plug in a value and forget about it.

I'm confused with the discrepency/offset inj scaling values downloaded by Ecuflash @ 420.23 comparing data pulled by Exxxxk @380 for the same Euro 2L wrx...

I'm looking for a close value you guys use for me to easy scale sti pink's with Ecuflash on my 2L EU wrx .....

The new formula in Ecuflash should get you closer to where you need to be. Think of it as an estimated value. This conversion is for your benefit only. It does not change the underlying value on the ecu. So, 380cc using xmlwrite and 420cc using Ecuflash are the same underlying value as stored on the ecu, just a different conversion formula.

guess I've to take it easy startin off may be ~500cc & work from there .... Thanks merchgod
