Identify the injectors?

[Stez]

May be someone know what kind of injectors can it be?

I can't see a pic. Also, Give us part #'s, or any #'s you see on them. That would help.

You can see the picture now...
One guy told that this is 680cc PTE, but after installation the behavior of them is some weird, it doesnt looks very different from stock ones...so i think may be this is not a 680cc???

Can you see any #'s at all? Also, look on the PTE site if that's "what they are" and compare.

They don't look like stock injectors at all. So look around them a little more, look for any #'s at all and compare them to what their "original" source is supposed to be.

yes, its looks like pte's 680cc, but i'd like also to chek with it's number, can you tell me where can i do this? on what site?

Try e-mailing PTE? DER!

They can help you with that more than anyone else.

Because without better pics, or exact part #'s, no one can help you at all.

How r u tuning them? and r u sure you're doing it all right? You kinda sound like a noob to me.

well, im really new in tuning

the strange thing is that i have installed them just and tryed to tune it, i though what due to the size 680cc bigger than 450cc to 51% i shoul compensate it to -51% with my Maft Pro in the main scale, i did it but the car begin to die, look like to lean, so i add some fuel and with compensation of only 30% it looks like somewhere close to normal work, wich i had with stock injectors
and another fact made me worry: my boost level now is only 0.6 bar, when i tried to tune fuel curve with this injectors - the DC were close to 75% - it looks to much for 680cc for only 0.6 bar.

Set the MAFT setting to 680's. From there, hook up a logger and see how things are panning out. Then add or - fuel from there.

Honestly, How is the car running otherwise? Boost leak testing? Plugs/wires?

But seriously, get TRUE pics of the #'s on the injectors, or just read the #'s for sure. It sounds like they are TRUE 680's, but it appears to me like you have another problem that's making your shit all "wonky".

Im running Maft Pro Speed Density not simple Maft, so there is no such installation like kinda 680cc or 720cc etc. There is the main scale where i can compensate needed % for all the range and also there is Low, Mid and High Load tuning. Due to the fact what i running Speed Density - such thing like boost leak should not to be a problem for ecu since it counts air in the manifold

But yes, i almost sure that i have some more problem with my ignition system, not sure is that plugs, wires or coils???? The wires are generaly new, so probably it is coils or plugs.
The problem is in that what during hard acceleration engine achiving the moment (somewhere close to 5k) and it a kinda stops and the rpm falls down, it not stall but rpm's falling down and i was really confused with that... During this there is no knocks and the car doesnot look lean or very rich... so the problem probably in the ignition

But i though that this my two problems are not connected...

Honestly sounds to me like you need to replace plugs (move to a colder plug, bpr7es's ######) and maybe you need an safc, or maft gen2 for tuning. OR, go ro the all out dsmlink.

You just need to find something that will compensate for the Injectors you have.

BUT MORE IMPORTANTLY! YOU NEEEEEEEEED to fix whatever mantinence issues you have.

IE, Boost leak test, FULL TUNE UP (plugs, wires, ect.). Check injectors and or clean them, check timing. You need to make sure the car is in TIP TOP shape before you tune. If you don't, when you fix what goes wrong, you'll have to tune all over again.

A good rule of thumb (which i know is WAY WAY hard to abide by with these cars) is "maintenance FIRST", mods later. You'll save youself headaches later.

 

[Stez]

Yes, i will defenetly start from plugs and will try to maintain my problem first!!!
As for compensation of injector - i dont need anything else, i have Maft Pro with which i can do it, the only problem for me was the % of compensation... anyway i will start from maintainance of my problem and only after that will come back to the question of tuning

Thank You very much for all answears and advises!

Yes they look like PTE injectors. If they are 680's like you think they are then try a correction factor of around 33%. 450/680 - 1 => from DSMLINK manual. GOODluck.

yes, i actually have compensation -30% - so it probably wright i just thought that it should be somewhere around 50% and this fact confused me.
Thanks for help
