fuel system questions

[Insane20]

Ok so on my talon I have an safc, denso 550cc injectors, aem wideband, evo3 16g, and an evo 9 fuel pump. After I installed everything I started it up and it runs just like it did before like I never even messed with the fuel system. The safc is zeroed out and my low throttle afrs are fine "cant drive it for high throttle settings untill my car is painted". My question is why are my afrs the same as stock? I thought I would have to set low correction for -18 to start but I it runs fine zeroed out. The only thing I even had to do was adjust the biss screw a little.

Anyone?

Most likely the added airflow of the evo3 and the maybe 10-15% more flow from the 550's over the 450's, and your fuel pressure still being at stock is just evening things out good. On my gvr4 I did the 2g maf swap and fic 550's and it runs perfect just like stock and I have the boost at 17psi and nothing to tune with , it just all evens out for the most part!

The only thing is I had the evo3 16g on my stock fuel system at 10 psi. I parked it for winter and while it was down I added the 550cc injectors and the evo9 pump and it would appear my afrs are still the same as far as low throttle go's. Ill have to run it and see where my high afrs are I guess. Thank you

Also a little off topic but is anyone using evoscan to log? If so has anyone had trouble getting the vag com 409.1 cable to work?

My guess is those are not 550s. Turbo doesnt matter at idle.

Is there any war for me to verify?

Heres a pic if that helps, the outlet is obviously bugger then the 450cc

It should be inscribed on them 550cc or something along those lines. But it looks like someone polished them for some reason .

 

[Insane20]

Someone scraped on the sides "550cc". I tryed running the part number with no results. They are supposed to be denso 550s.

Either way they definitely are not Factory 450s, anyone have a clue what I have here?

Also I do know they are low impedence, I measured the oms.

Dose anyone have a link for an injector identification thread or something, I've been searching all over and cant seem to find anything.

Ok I think I found what im looking for.

According to that thread I have 535cc injectors, since I already have them in im going ti give them a shot and see what I can do with them.

There won't be any difference in idle with those injectors, evos run 560cc pink top injectors, that easily swap into any dsm .
The evo fuel pimp is only 190lph, you honestly haven't changed much to the fuel system, more like updated it.
Now just get you a 3G or evo 8/9 MAF, you'll be good to go.

 

[Insane20]

Hey as long as my fuel system gets me to 16 to 18 psi on the 16g ill be happy!

 

[eclipserst96]

True true.

Any ways though, dose anyone have an input on running the vag 409.1 cable with evoscan?
