Alright well i start my car and the gauge goes to super rich --- but when i give it just alittle gas bringing rpms to 1000 it is on 14-15. im still new to this gauge so any help will be appreciated. also i just now found out that my downpipe is leaking horribly right where it connects to the s-pipe. the sensor to the wideband is on the s-pipe so will this cause it to give this reading????? this is the first start-up since turboing the car so that is why im concerned thanks

 

fix all exhaust leaks before you take ur next step

once done youll see a whole new set of afr's

 

your gauge is not accurate since you have a exhaust leak!!!

 

okay so fixed the leak and readings are as follow. at start-up the car is between 14-15 all the way till warm up. crusing speeds 13-14-15 between there. under boost 11-12, sometimes it hits ten but its real fast then back. okay heres the strange part after a cruise when i shift it flat lines --- then goes back to normal and when i hold the clutch in to like slow down or down shift same thing...now after i get back and have it idle it flat lines ---???? confused as to how this happens *note i currently cannot tune due to the fact that i have a treadstone kit still awaiting the ultimate that is on it way. thanks for the replies

 

when you shift it will do that....its called fuel cut....when you engine break it will do that as well.....as far as idle it should be at 14.7

 

idle sits at high 14s and taps into 15s sometimes it kinda fluctuates between there. also it flat lining like that when i shift and engine break is it safe cause i really don't want to mess anything up

 

When you back off the gas you go into open loop OR Fuel CutOff since you don't need to inject fuel into the engine when slowing down or between shifts when the engine is reving down. At those points there is no reading from the O2 sensors that make any sense. Sounds pretty normal - you just haven't seen it before.

 

after i get off boost if i got on it kinda hard my car stalls.. like 5 other peeep have my same prom..... mayb it will go away wen i get tuned

 

GEEZ these posts are so close together we should be talking on the phone!

 

Jan06xb your right i have never used this gauge before so i really don't know what to look for as far as readings. i built many cars but im really sad to say that this is my first turbo car i built did alot of research thou

 

you should be fine man.........just dont boost all the time till you get tuned......your stock ecu is controlling most of your driving right now

 

I remember the first time I used the ScanGauge and watched the fuel burn rate go all over the place - you don't realize how easily your gas foot moves without thinking about it to keep the car going steady.

Stabbing the gas after coming off boost probably is a tuning issue. You get some wastegate response and boosted air rushing in suddenly and the ECU hasn't been adjusted to handle it yet. Sort of the thing you used to get in the carb days with the accelerator pump that would inject extra fuel when you stabbed the gas pedal to make up for the intake manefold vacuum sucking in a bunch of air when the throttle plate opened up even though the engine is not sucking it into the cylinders yet there is still a mass of air that rushes in that needs some fuel added to it.

 

thanks for all the response guys i really am at ease now that you say it should be okay as long as i don't pound the living hell out of the car. which i don't plan to i've blown my fair share of motors not looking into the that again hahah

 

okay just got back from the gas station and got some weird whistle coming from the car...i can't believe im saying this it sounds like the Eclipse whistle from the F&F 1???? check everything all is normal burnt my damn hand checking the pipings on the charger itself. im so confused on this one

 

a whistle when......when your going fast?....when your in boost?.....when?

 

it whisltes after the bov goes off and i let off the throttle hahah sorry i didn;t specify

 

omfg........all i have to say is o...m...g.......you said you have built motors before right?....so id assume you are pretty car savy.....well the whistle is coming from your bov......its releasing the extra air.....i really hope this isnt what your talking about.

 

oh and the reason why your car is stalling.....is because your bov is venting to atmosphere......it happens on almost every car that has a MAF that is running an atmospheric bov that isnt blow thru.....im gonna give you a tip man..........use the search button before you start messing with another car

 

hey man the whistle is after everything the bov goes off and then it whistles about a second after so im not to sure if it is or not
