Can some one help?
Is this injector set up right original 850cc and boch ev14 2200cc no resistor?



Thanks,

You're going to need negative lag with those 850cc. Why are you running them? Put 550cc primaries back in. 550/2200 is more than enough for most single turbo setups.

Otherwise, those secondary injector settings should work.

Thank you,

i don't have 550cc injectors anymore.

How much negative lag i need?
Is it voltage vs lag set right?

Set the primaries at 64.7%, not 68.0% . I do not ever use negative lag for OEM 850cc primaries to function correctly. However you do need the have the primary rail machined so that they fit in the rail properly and prevent leaking.

I have found that with the proper mechanical throttle body adjustments, I can get the 850 primaries to idle smoothly at 800rpm with 13-13.5 AFR, and controllable to much leaner 14-15, obviously at this point to idle stability is gone.

Thank you very much.

I know I'm reviving a thread, but better than creating a new one right?

I'm running into issues with 850 primaries, namely it idles rich at ~11 AFR and will not change. You say you have mechanical settings that would make it idle a touch leaner? Can you elaborate or share? I bought the car with the 850's in there and a milled rail so I'd love to save money and avoid downgrading to 550's (at least for now).

Running negative lag makes the car super unhappy: surging idle, stalling, delayed response to throttle input. I don't consider it a viable solution.

transition on the first picture should be 1.000 not .100 1.500 was from factory.

I run 550's 850's are overkill

1650 ASNU in secondaried good enough for 500+
