Hey guys. My tuner needs help tuning my car with the new ID1000s i just put in and getting my speedo correct with the new 6spd. Any one help? My afrs are 10.3 wot. Im on e85. Turbo swap. I can email logs

My idle jumps a bit. Any help is appreciated

 

It looks to be over the ports but I'm not sure. I'm back from work in 2 weeks and I'll get a picture then

I'm not looking to go over 400 Hp. -6an isn't big enough?

 

That's only a 3/8" hole.

 

I mean I guess 4 of them would suffice at -6. But I would run at least -10 or -12.

 

Worst case is I'll use my spare and weld bigger ports on it

 

For which line

 

Lines coming from the valve cover.

 

I have a file setup for ID1000's and E85 from Blazin's car, if you wanna shoot me a copy I can see what's different and advise. Italianjoe1@hotmail.com

FWIW, the idle will never be perfect, if you are running enough fuel pressure to support solid boost. What is your base pressure? IIRC Josh's car is around 50psi and the idle is a bit higher than stock to be smooth, but the injectors are 3x the size of stock so that's to be expected. The car drives awesome though.

 

Base fuel pressure is 52psi.
Ill have him email the file to me and get it over to you asap. Thank you

 

Ok at that pressure you should be fine, I believe we are under 90% IDC at 26psi. E85 needs fuel like a ************

 

Your idle as italianjoe said wont be perfect, the thing to make sure is that your stft and ltft are within a few percent. You afr, crusing, and just drinving around in general should bounce around 14-15, under WOT depends on your boost level but if you are referring to e85 stoich then 10.3 is bad as you have indicated.

 

And your theory here?

 

my base pressure is at 43psi

 

I'm surprised that's enough for you... What's your idc and afr at redline?

 

Well he doesnt seem to think he needs to adjust cells individually. Hes richining and leaning all cells together. I dont like this. First he tells me hes tuned a few LSJs and now hes like im the first one..... im still waitinf for him to email me the tune

 

duty cycle sits around 80-83% and it's 11.8-11.9 in gasoline afr with e85

 

Is he a subaru tuner by chance?

 

Lol I dont think so name is scott. Lives in mich and has a turbo 3800 fiero that ran a 10.00 1/4mile

 

incorrect

not on the lsj

lol

An internal combustion engine is built around a series of hollow cylinders, in each of which is a moveable piston designed to glide up and down inside it. A mixture of air and gasoline is pumped through a system of tubes called the intake manifold through each cylinder's intake valve (or valves), where a spark from a spark plug causes the mixture to explode in the open space at the top of the cylinder called the combustion chamber. The pressure from this explosion drives the piston in the cylinder downward, where it causes the crankshaft to rotate. The rotation of the crankshaft not only pushes the piston back up into the cylinder so it can do all this again, but it also turns the gears within the car's transmission that eventually make the car move. Meanwhile, the rising piston pushes the air and gas left over from the explosion back out of the cylinder through an exhaust valve.

However -- and this is where crankcase ventilation comes in -- a certain amount of that mixture of air and gasoline is pulled down by the piston and slips through the piston rings into the crankcase, which is the protective cover that insulates the crankshaft. This escaping gas is called blow-by and it's unavoidable. It's also undesirable because the unburned gasoline in it can gunk up the system and produce problems in the crankcase. Until the early 1960s, these blow-by gases were removed simply by letting air circulate freely through the crankcase, wafting away the gases and venting them as emissions. Then, in the early 1960s, positive crankshaft ventilation (PCV) was invented. This is now considered the beginning of automobile emission control.

Positive crankcase ventilation involves recycling these gases through a valve (called, appropriately, the PCV valve) to the intake manifold, where they're pumped back into the cylinders for another shot at combustion. It isn't always desirable to have these gases in the cylinders because they tend to be mostly air and can make the gas-air mixture in the cylinders a little too lean -- that is, too low on gasoline -- for effective combustion. So the blow-by gases should only be recycled when the car is traveling at slow speeds or idling. Fortunately, when the engine is idling the air pressure in the intake manifold is lower than the air pressure in the crankcase, and it's this lower pressure (which sometimes approaches pure vacuum) that sucks the blow-by gases through the PCV valve and back into the intake. When the engine speeds up, the air pressure in the intake manifold increases and the suction slows down, reducing the amount of blow-by gas recycled to the cylinders. This is good, because the blow-by gases aren't needed when the engine speeds up. In fact, when the car is up to speed, the pressure in the intake manifold can actually become higher than the pressure in the crankcase, potentially forcing the blow-by gases back into the crankcase. Since the whole point of positive crankcase ventilation is to keep these gases out of the crankcase, the PCV valve is designed to close off when this happens and block the backflow of gases.

 

Y do u think the port on the back over the valve cover has vacume wen the car isnt boosting.

An increased size is good to alow better flow

 

it has vacuum from the intake side not the engine side plug the hole and see what will happen

 

Mine has vacume pulling into the valve cover

I checked it lastnight

 

im gonna have to call bull **** on that and this is how I know when I bought my intake from ottp I put it on fired up the car and setting there idling about 10 min the dipstick popped up I didn't think anything about it went to meet a buddy and on the way home the dipstick belw out and oil was everywhere the next day cleaned **** up and got to looking and you run the engine and hear the pressure building in the engine pull the vent line off of the the intake and air pressure would run out of the vent line after looking at the intake I seen they put the bung on for the vent line but didn't drill the hole so I drilled the hole problem solved

 

Wen vacume drops the valve in the mani closes.. So if u boosted even a lil with out the vc vent pluged it will blow the dip stick oit.

 

not at idle it dose not shut
