yeah. i really just want to make a separate hole in the manifold for it

 

holy crap i got a cel today and this is what came up...


Diagnostic Codes:Oxygen Sensor
Intake air flow sensor
Throttle position sensor
ISC motor position sensor
Engine coolant temperature sensor
Ignition coil
Ignition circuit

 

like...all of them?

 

yeah all at the same time... i stoped at a sign then right after i turned. and got hit with that mother load.. my car seems fine... except for the osculating afrs... so i cleared them and if they come back i guess i will have to replace them. probly gonna replace the o2 sensor anyways.

 

Wow man that honestly sound more like an ecu possibily on the fritz and may or may not be ready to quit on you. One component (like the ecu) failing is alot more believable and probable than all those sensors failing at once.

 

That is exactly what I was going to say....a ton of diff things all at once, it's more likely 1 thing fails than 5 at once. But...I see a lot of CELs when I change things that throw my entire tune off...like timing too low, I see too lean, misfire, egr, who knows. As soon as I clean those issues up, the random CEL's go away.

Nother thing I was thinking. As of recently, my flashes to the ECU seem to take 2 tries sometimes, once it took 3 trys, and I was thinking "i wonder if my ECU is failing on me". Do yours always take right away, first try?

 

as far as i know it takes it right away...

i got the cel again

Diagnostic Codes:Oxygen Sensor
Intake temperature sensor
Throttle position sensor
ISC motor position sensor
Engine coolant temperature sensor
Crankshaft position sensor
Camshaft position sensor
Knock sensor
Injector circuit
Fuel pump relay
EGR sensor

 

Hrmm hornstar that sounds suspiciously like the "flash limit" issues I heard about when I first started reading about tuning. Although Aaron from English Racing assured me this is not true and mine has always taken first try...
Wow man 7 the first time and now 11?????!!!!!!! Do you know any lancer friends close that would let you swap in their ecus for a bit?

 

hahahaha i dont know any of them but i see about 6 different ones on a daily basis.

i can tell by the looks of it that they are all pretty conservative lol

haha i dont think any of them would let me borrow their ecu

 

try using something else besides the evoscan to read the codes. Maybe go to Autozone and then compare what they got to what evoscan is saying.

Oh, and burner my turbo is not blown!!!!!!

 

yeah i will definitely do that if they do pop up again. i copied all my settings into a new rom and its working great so far.

lets get your show on the road man im tired of you laggin behind!

 

I'm tired of being behind bro as well.

 

ok so in closed loop my idle afrs are 13.8-14.6 most of the time.
the vac is -10

when i change it to forced open loop my idle is low 11s normal but vac is 20

what would effect vacuum between closed and open loop??

 

ok some more info about the problem...

the vac bounces between 11 and 13 inches of vac

when the idle fuel trim starts changing the vac goes back to 20 and then once its done slowly and bouncily rises back to 11-13

when i step on the gas and rev it a little the vac will go to 20 and then slowly bounce back to 11-13

 

any help? triple post :/

when i unplug the left vacuum solenoid the idle vac is perfect 20.

i posted a diagram on page 9 post #130 of the vacuum diagram its the one on the left.

in the fsm it is called :

EVAPORATIVE
EMISSION
PURGE
SOLENOID
