What size injectors do I have???

[kgtalon95]

OKay guys, I know this sounds stupid but I have a feeling that I might have gotten the wrong size injectors

I ordered PTE 660's, so approximately where should my settings be on my AFC for low, high maps?? I'm running around 16psi on a b16g, the highest high throttle map is at +5%, while the lowest low throttle map is at -10%.

I also have a 2g mass that flows more air so keep that in mind because I've heard it pulls down the %'s

Does anyone know of a way to check the injector size?? I've really wanted to know the answer to this question for months now

Because according to the tuning guide the base settings for 660's should be around -18%???

The reason I'm asking is because I'm trying to get a my ecu chipped for injector compensation and I really want to make sure I have the injector size correct!!!!

The only way to truly tell is to send them the someone place like RC that can flow test them. I don't know if you can tell just by looking at them.

*I am not positive about this* but, i think you maybe be able to look under the o ring that seals it and it may say the size. I know you can tell on some, i have checked some before, but i'm not sure about yours. Its worth a try I guess.

+1, but i would send them to cruzinperformance. they ONLY clean injectors, no sales. very unbiased, AND they flow them at different pressures. very complete clean/flow service, and very reasonable, too.

Just out of curiosity, where did you buy your injectors from? I just got a set of PTE 550's and they seem like they are the wrong size also. I don't want to post the name of the place here, but if you get a chance PM me. I think someone either at PTE or at one of their distributors is switching injectors and boxes around or something. My 550's seem like they're 660's. I'm tuning mine with a MAFT though.

pte's flow less than what they say. Usually 680cc ptes flow about 650

so do fic's. my BRAND NEW 650's flowed less than the stock 450's. delphi is delphi. they suck.

Well I got off the phone with them and they gave me some numbers to cross check and they appear to be correct, 680cc. But judging by the info in my first post is that where my maps should be?? I've always thought that the base with those injectors on a 1g should be around -20% for low throttle.

Is it because I have a 2g mass that is flowing more air and thus making my base setting higher??

To give you an idea, i have a 2g with denso 660s and a 255fp on a 50 trim and my settings are in the -30% range for the hi's from like 5k on and this is running 20-21psi.

Your base should be around -17 I believe with a 2g MAS. I have a program at home that you enter in your information and it gives you the correct settings. I'll post link when I get home.
