Was wondering if anyone has had this issue.. recently car has started to run rich under boost. Just a random occurace.. no changes to sfac2..
I swapped the air temp sensor with one from a 2j. The problem was fixed.. so I added fuel back in to the curve (I took some out trying to fix the rich...
since this i have picked up a divided 6262 . i can remeber the turbo that is on it now. i think it somewhere near a 57 62 with a 64 ar.. percision . so new twinscrol should be alot better for my car.
and that is at 21psi. his map on the dyno is off
Could have a small leak at the turbo or even at the head. I coated all my gaskets and bolts with wheel bearing grease as it burns off it will turn to carbon and plug small holes or flange inperfections.. stinks like. Hell for a day or so. But helps out with exhaust leaks
I am running 440s. And a wlbro 255 in tank.. also stil running the fuel dampener.. and stock frp. And a sfac2.. at idle I'm pulling 9percent.. at 4500 pulling 15% and over 5k 18 to 24 percent.. I am adding fuel only one time like 1% at 25oo rpm on the low side.. are u sure that your wide ban is...
HA HA HARDY HAR HAR.. are we back to this? i own my own home. and own all my cars 3 of them. not poor just work for my toys. respect not wasting too much money.. i dont need to spend dollar to get pennies.
why spend the money on a 2j when i can get 500whp out a 1j for less simple choice.. i...
well 14.5-14.7 is boost cut.. also if your running a tru boost ? i needed to turn mine up 4 point at a time to get 1 pound increase.. but my leak was out of a bolt hole on turbo that i missed.. huge oversight.. i also had 3 more on ic pipes and one at the throttle body
I would belive that. I will look later but I have to pull a lot of fuel out like 20 percent. And every system is different. Butwith more fuel pressure u can make them think their bigger and I'm on stock fpr.
yes tht is on the 440cc.. and the onlu issue i had with the booster was intake clearance. but its no big deal. going to build new intake next winter. and i am running the toyota ps pump so i dont think that would work, but it is a good idea.. its funny i asked that question on the bimmer forums...
back to the dyno today. car made 21.5 psi runs great no knock good fuel. . andno leaks.. all issues fixed and here is the resualt . i will post up the whole graph once i get it emailed to me
my car did this also.. and it says that you adjusted tps? back to stock. did you use a volt meter to calibrate it? on my car if i mess with the idle screw (at all) or if the tps is out even the slightest bit it will have the same syntoms yours has.. maybe take a 2nd look at tps. also reck the...
