well when i watch the injector width pulse it gets up into the 20 range
from what i have read that is 100% duty cycle but i could be wrong

ok thanks for the advice i might hook up the wideband tomorrow
also i have a set of 21# injectors cause i think im maxining out my 19# ones will it help or no or do you think i will need 24# or something
thanks again

ok i do have access tyo a wide band and yes i am pi swapped
it just seems like there is more in it and i am tryin to figure out why when i try to lean it out richin it up or even change some timing it goes all crazy and makes the injectors run almost 100% duty cycle

so im gettin absolutely no support here

i would really like to get this figured out

ok well like said on here simple bolt ons work great with it but when you start modding it you need more and well im a little more modded then just bolt ons.


so if someone with alot of knowledge on this thing or 98's at theat could help it would be great i could really use some help


o and for ...

it runs low 30's on vacuum and 40's with no vacuum i just checked it multiple times

the weird thing is i can use the diablo tune but when i try to adjust it is when it ghets all messed up so i dunno
any ideas?

ok i checked i have nothing bolted to the fuel rail
not even a place for anything like that

could it be a inline vacuum sensor or something

as far as i know you just go into modify tune selrct axle and then select the gear your using

i dont think i have anything bolted n top of my fuel rail. where isd it located.
i have a 98

Check the FRPS, if it reads wrong, will do wrong things. do you get a P0190 code?
the what??
not sure what that is......
no codes i have the mil off but when i turn it on the light will come on but when you check it it says no trouble codes...but when you go to clear it it will clear.
before it ...

also i forgot my mods i guess

ok sio i have a 98 mustang gt
and when i try to lean the fuel a little or anything at that the inj pulse width gets all messed up im not sure if it is supose to but bank one will be at idle about 1,4 and bank two will usuaklly be about 3.4 or 4. 5 and only gets worse when you accelerate.
and it gets ...
