hi, i got an STI 2006 (european version see below)......it s a 2.5L



i Changed the injectors for 750cc deatschwerks. I put a parallel injection ramp (perrin) and a TD06 20G, a bigger fuel pump.I changed nothing else.

I'm trying to set the injector scaling but it goes wrong.I declared my injector as 705cc (cause my fuel learning positive +14%). It's strange cause they should be 750cc!!!! So i decided to work on latency and it seems better.

I don't understand why i had to change the latency (to increase them) as deatschwerks tol me to set oem latency (see below)

6.5V 4.7ms
9V 2.65ms
11.5V 1.73ms
14V 1.2ms
16.5V 0.91ms

So do you think it comes from my new injection ramp? What are your OEM latency times on USA models MY07? Thanks

I had to scale my 740cc DW injectors as 720cc in order to get them to behave the way I wanted. They have been working great scaled at 720 but I would love to hear more on this subject.

seems good for me as 700cc whithout changing latency.Did you change latency and what are yourse ?
