I really dont know much.so i need your help guys.i have 99nb turboed using voodoo box. my car is running very rich with the 2000 miata injectors.im thinking to put back the 99nb injectors.do i need to tune my car again with the 99nb injectors??

 

No the car will magically know how much fuel it needs, it's running too rich right now because you make it feel self-conscious.

Hint: 99 and 00 injectors are the same.

 

LOL thanks for your reply.im sorry im using the purple injectors for 2001.so do i need to retune when i put the 99 injectors back?

 

Going from 265cc to 260cc, gonna say no, but it sounds like you could stand to anyway.

 

lolol 5cc

 

Actually, IIRC, '01 injectors are sized closer to 240cc at 3bar, despite what I've published elsewhere long ago.

But my questions are:

How rich is "very rich?"
When is it "very rich?"
How are you determining this?
Why can't you tune it leaner?

 

No one's said it yet so I will: ditch the doo doo box or settle for mediocrity

 

i have a wideband it goes gradually to maximum rich when i hit the throtle all the way to the floor.then it goes back to the middle when im off the throtle.but when i hit the throtle a little bit it goes to maximum rich for seconds which causes my car to stall for little bit!!!! and thats my problem.by the way i have walbro 190

 

 

I smell a ban.
