so heres the story. i just got tuned on saturday from Trifecta and has Vince tune out SAI or so i thought. i still have stock header and everything on so that when i do want to get my LSJ header on i wouldn't have a code for the SAI being disconnected. well story goes that i turn my car on for the first time after the tune and what do you know. that ******* vacuum like sound is still coming from the SAI pump.

does anyone know if when vince tunes out SAI he is either tuning out just the CODE itself or the operation of the system as a whole. cause i thought after having him tune it out i wouldnt have to hear that noise anymore.

maybe he just forgot to tune it out?

i won't get the header on for at least 4 or 5 days so if it turns out that he didnt do it i wont know til its too late.

anyone else have it flashed out before actually getting the header on? and have had the same problem. and maybe can tell me whether they got a code or not even though the system was still working prior to changing the header?

I don't think he tunes it out as much as he shuts off the cel

blackbolt89

so im just going to have to live with that God awful noise that i was longing to be gone? damn

anyone else have any input?

thanks for your quick answer though man

D4u2s0t

you won't have to live with the noise because when you take off the stock manifold you also will remove the entire sai system from the car.

blackbolt89

oh i know that but as i said i'll still have to wait for about a week to get header and dp on.

speaking of which would you be free anytime this week to maybe help a brotha out?

for a fee of course

did you talk to him about it?

blackbolt89

well i had a local trifecta dealer send vince my email with what i wanted done.

i just wanted to know if anyone else had him tune it out and had it still running after they got it flashed out.

Dude if hearing it bothers you that much, just pull the fuse for the pump.

Pluse you will be able to see if the light comes on.

blackbolt89

lol. im pretty sure there's more than one. and i dont even know which ones to pull. would they just be the ones labeled air pump?

slowswap

Turns off CEL for that code.

blackbolt89

so does anyone know which fuses i have to take out? theres a few that say air pump but i want to make sure that those are the only ones, and that they ONLY control the pump. some of them relays look like they do more than one thing.

idk

I would start by pulling the air pump fuse in the underhood fuse block

avenger09123

What happens is inside the ECU the code is deleted from the list (so to speak) so if it doesn't find the relays or the power doesn't apply to the pump, solenoid and so on it will still run the diagnostic but look through the list for the code to throw and not find it, thereby eliminating the CEL....

As for pulling stuff from the fuseblock to prevent anything and everything from SAI from running...the map is on the inside of the lid, you can pull the air pump relay and fuses and the solenoid relay and so on...hold on a sec I'll go outside and tell you everything you can pull....

AIR PUMP 40A - fuse
AIR PUMP - relay
AIR SOL/AFTERCOOL - relay (I think we can pull this one, because we only have 1 air solenoid on our car, but test it just to be sure)
AIR SOL/AFTERCOOL 15A - fuse

i'm working on a simulator right now for it with one of my buds here in town who has way more microcontroller experience than me, but we're hoping to market it here soon. I need some money haha, the army and UNLV has made me broker than a bum.
But basically all it would be would be pulling out all of the equipment, unplugging the solenoid/pressure sensor in the back and plugging this chip in. I'll keep everyone updated because it'll be cheaper, and easier, than finding someone to tune our cars....

blackbolt89

im not gonna mess with the air solenoid ones but if i pull the 40 amper and the relay will i get it to shut the pump off? i just want to make sure that the code is gone. cause driving back to new york to get a retune would suck.

all you need to do is pull the "air pump" fuse in the fuse block.

avenger09123

Well I looked in the book and as long as he deleted the 20 something codes related to the SAI system....you should never see a CEL again. And yes the fuse would effectively keep the air pump from running. However I don't get the reason for having it flashed out if you are not going to remove the equipment....seems like a waste of money to me...

Just listen to that post.

well eventually he'll be removing it .. however he didn't get the stuff installed in time..

kyle demmit why you never believe me lol i hearby relinquish your name of kyle lol

blackbolt89

oh stfu kyle.

and btw i didnt have to pay more for the sai flashout... i got it done with the rest of my tune. lol.

i wouldnt pay 200 bucks for just a sai flash. i would live with the cel if that was the case.

i should be getting my header and dp done tomorrow. anyone know about how much it should cost?

D4u2s0t

free if you do it yourself.

thats the same thing i told him but he does has the tools

D4u2s0t

can get everything you need from walmart for about 50 dollars, including a floor jack and jack stands. that's going to be way cheaper than getting someone to install it, and then you have the tools for next time.

when i first started getting into cars, i was just going to take it somewhere. when i started looking at prices, it was just insane. pay someone else money to twist some nuts and bolts. figured ****, i can twist some nuts and bolts for free

yea i've only paid for 2 things to be installed .. 1 was tranny mounts because my car was already going into the shop and i don't have a press.. and the other was actually my header and dp because i was at school so i had no place to do something like that to my car and it was the first thing that being done to my car outside of lowering the car.. but after spending money on the header and dp i was like .. screw this ...esp because I hate it when something goes wrong .. and some one else did it .. that means they got paid to not do something right...if i screw something up i can only blame myself
