ok well first my question is what size are they because ive read alot that they are 410cc and i see here that http://www.scionride.com/forum/index.php?topic=604.0 says they are 400cc


also what color are the injectors ive seen some that are green and some that are blue wtf color are they

Ive heard conflicting reports on the size also - however I can tell you for sure the color is a darkish green compared to the color of the stock injectors which is like turqoise greenish. I can tell you though Ive been running my setup with the TRD injectors and my FIC for about 9k miles now. Im running a 7 psi spring in my wg but peak around 7.5-8 psi on my t3/t61 which is a fairly large turbo - and the injectors keep up just fine - im running at a perfect 11.4:1 afr under w0t boost right now even with temps getting down to 40F outside. I had it up to 9 psi earlier (making 9.5-10 psi according to fic datalogs) but had some fueling issues in the high rpm rang (it would go up to about 12:1 near 6k) so i turned down the boost back to 7.5 - i had the fueling a little rich previousely and it had no trouble hitting 10.2-10.6:1 afr under w0t boost at 7 psi so i know with the current setup im prob getting close to maxing out the injectors but they def have a little headroom left - the fic idc shows between 70% idc to 180% idc and once it even showed like 300% idc so i def wouldnt trust that as a fair estimation of true idc. However im looking to sell mine soon - I wanna go with 700cc-1000cc injectors as I plan on going to e85

^^ ima use 410cc for just 6psi and then up the cc to 440 for 7-8psi i am not looking for killer power and dont want some stupid fuel trims with large injectors

iv seen 200 something % but it was narrowed down to a voltage spike so it happens and i dont think the fic is exactly at fault (in my case it sorta was). it was intresting how it happend, i was tuning a guy that didnt have the cam/crank rigged with resistors (using the fic) and around 5000rpms the car jerked 3 times and when you look at it through data log it shows the injectors spikeing in the same spot the car surged. it showd over 200% duty cycle on the injectors. Kinda goofy but i swapped out harness with one that had the resistors already in, ofcourse it cleared up the surging and the injectors didnt spike. so i have to conclude it was a voltage spike that screwed with the fic.

Hmm my crazy idc's didnt seem to have a correlation to any actual problems lol - afr was normal across the board and i had no weird stuttering issues or anything - kinda strange really it just depends on the day sometimes it shows normal 72-78% idc - some other days it shows like 180% idc - i dunno

I really think its a voltage issue imho...it screws with the fic hardcore...do you have a system?
