ok so talked to foff he thinks its ok. when i go in closed loop the idle sucks. the IFR table is made for the correct pressure changes and the right injectors. it should be perfect. the oscillation of the o2s sucks at idle too. i dont know if there is somethign else that needs to be done or if i need to wait for the cam install when the car needs more fuel.

so any ideas?

 

Saw this on hptuners boards also...If you scale the IFR table that should have fixed everything. My buddy just installed Racetronix injectors on his car and his is perfectly fine (42 lbers). We used the calculation given in the hptuners thread to tune the IFR table.

4/3 = 1.33333
take sqrt = 1.155

1.155 is then what you multiply your injector size by. In my buddy's case they were 42 lb injectors so they become 48.51 lb injectors. If you got the 37 lb injectors you would get 42.74 lb'ers. So then do this new number divided by your old injector size (26.4 in your case) and thats the multiplier you use for the IFR table.

42.74 / 26.4 = 1.61875

So multiply your IFR table by 1.61875 and that should take care of it.

 

ok so 1.61875? mine was done by 1.65. they said that at 4 bar they are rated at 43.65 and that divided by 26.4 is 1.65. like i said thats what is in the computer now. would that .04 even make a difference?

 

I wouldnt think it would make too much difference. Check all your connections with your injectors, o-rings, etc. And if you had to take off your intake to install the injectors make sure you dont have a vacuum leak or anything.

 

ive checked them all they are all fine. unless one of hte injectors just flows more or less than others
