Ok so a shop put a turbo timer on my car and I think they hook it up wrong or just did not finsh the job the timer works fine but A/F does not work and the O2 sensor is all over the place not even close to what it should read so my main question is, is it hurting my car and is it safe to just turn it off well driving then turn it on when i need to use it?

 

umm what??? what does the turbo timer have anything to do with calculating A/F??? or the O2 sensor?

 

Its a Apexi tt and comes with those functions

 

those functions are not accurate, for correct a/f ratios u need to get a wide band

i had one of my eclipse and it read but was not accurate.

as long as ur timer is letting the turbo cool down than your all set

In closed loop the voltage is going to oscillate so if you are seeing numbers rising and falling quickly while in closed loop it is reading correctly.

That said it is next to meaningless.

 

Thanks for all the info I was just scared that they just plug it into my ecu some random place

 

I plug my car up to a obII scanner and everthing is fine but the o2 senors on the timer reads like 4.87 and jump all around even to 2.88 I am just pariond that its hurting my car

 

trust me bro, i had this turbo timer before. i am sure your car is just fine

 

unless the number 1 is burnt out on ur tt lol

also that turbo timer cannot alter ur a/f's its simply taking a reading so it would cause no harm
