After we tuned my car and unhooked the wideband. I went and connected the stock O2 Sensor and went to start the car and it did not start smoothly. It would not idle for crap and was hard to start. As soon as I disconnected the O2 sensor the car started right up and idled fine without any problems. I have 02 feedback turned off on the aem. Any suggestions why this would behave like this?

 

Bump... I would like to know this too!

 

Was the car tuned w/ the wideband wired into the EMS, or just for dyno tuning?

 

hey chad you should try to get aaem uego or anopther wideband. what was the tune air/ fuel at when it was ideling?

 

also i am thinking about going back down there in a few weeks. aree you iinterested?

 

to add in, since im the one who tuned it, o2 feedback is turned off. so it should not affect anything when the o2 sensor is plugged in. the afr is around 14.3-14.7 at idle. the car was not calibrated for the wideband o2, and also not hooked up

Josh,

Kyle (the owner of the SC'd teg) wants me to come back up and tune his car when he gets another pulley, and also his cousin. Thats two people for sure right there.

maybe we can talk manny into coming back when he gets his new injectors.....

then we can have another dyno day but this time it will be much more organized.

 

I should be able to stop by next time around. Im thinking about a new setup and going straight GSR now using our new step-decked blocks. Yumm, 2.2 liter goodness.

 

ok well i will be tuning my own car this time. i want to do some back to back comparisons on new cams and headers.

 

is it still true you cant use a stock o2 sensor with the EMS?

 

no you can use the stock one but its not very good. i didnt realize how in accurate narrowband o2 sensors were until i got a wideband

 

i'm down all I beed to get is bigger injectors and get my avcr put in and I'm set!
I wanna take this small turbo to the max!
Just got done christmas shopping for 11 neices and nephews and now it's back to the car .

 

k guys thanks for talking about tuning in my o2 question thread

Yes as Mase said the wideband was not wired into the aem ems. Which makes no sence why the unit acts all funny when it is plugged in. On my old car I could unplug my stock o2 sensor and plug in my wideband without any problems. It is like something is grounding out when I plug that in. Is there any other changes that may need to be made in the aem software or any pins that need to be unpined?

 

why do you want to plug it in? Sounds like a sensor ground problem. I know that if i hook my ground output from my fjo to the sensor ground on the aem that the car will not idle and all sensor readings are way off.

 

the reason I want to plug it in is so everything is right on the car. The other reason is so my pos autometer a/f guage works. Is there a way I can test or trouble shoot the ground or the wires to see if it is a bad ground or what.

 

it takes my magical touch, just like you shitty starter

 

hey chad if you want to come down to philly i can take a look at it for you.

whatever happend to the starter?? did ya end up buying a new one?

 

the starter started to work again. I think it was a combo of a dirty ground and there was a lot of grease on the starter where it bolts into the tranny. I think it just was not making a good ground

 

i forget if it is the white or the green wire at the o2 sensor that is the o2 ground. you could figure it out with a multimeter and check which wire has continuity to the sensor ground at the ecu, then i would depin that wire at the o2 sensor connector and see if it solves the problem. maybe its a bad o2, did you have any codes with the hondata hooked up? in closed loop?
