wide band questionnnn
 
okay so I was running a 6.1 fuel disk because my car was running very rich in boost with the 7.1 ...but I put the 7.1 disk back in because it was jumping over 13 with the 6.1 for no more than a split second and then drops to 12 11...etc. after gettin' into full boost.

any advice on how to run my car more efficiently?

also...occasionly when i'm just doing some normal driving...if i step on the gas just a hair...it leans like crazy according to the wideband and it feels like there is hesitation... probably normal?

I bought this car from snowsurfer(my cousin) casue he is going over to fight some guys overseas and stuff. So i figured I would an a e manage system maybe the ultimate? and get it tuned so it runs really well!!!

so any advice on fuel disk? and hesitation? lag from the turbo? i just don't get why it leans out like crazy.

$10 says you don't have an o2 clamp......

i take pay via paypal...i do. and yes it's on and running been checked.

would you believe i had my fingers crossed when i typed that :gay:


you need to tune the voltage on the box or make sure the pressure switch is still working....got a multimeter?

speedracerTD04 04-17-2007 09:58 AM

negative...but I know people that do... how do I tune the voltage? gahhh... i need help. thanks though.

it's true...I'm a newb here.

all the clamp does is modify the o2 voltage to the ecu when the pressure switch is activated....if the switch doesn't work anymore, then the clamp won't output anything. So first verify that works....listen for it, you should be bale to hear it click when you get into boost....if not, then it may need replacement.

you'll tune the voltage by turning the little brass screw on the box....closer to .47v will make the clamp do nothing in boost, closer to .3-.2 will add more fuel. Read the voltage off the black Ground and white wires. adjust it by .04 increments or so, it's pretty sensitive. you should be able to see results on the wideband right away.
