my N75 isnt attatched at all. i just have an mbc in its place, could that have anything to do with it?

 

Just wanted to put my input in everytime you touch a coil-pack you are risking of it going bad because they tend to crack and when you do pull the coil pack off your making the crack larger.

 

The N75 must at least have the harness plugged into it.

 

ok. i plugged the N75 back only electronicaly and its running better. on first start up, it doesnt smoke but after driving a little bit, it misfires just a little bit on partial throtle then smokes a little bit on idle. now while its smoking, if i turn the car off for 2 mins and back on it wont smoke until i drive again. would it help if i hooked up the vacuum lines to it too? and then just hooked up my mbc parallel?
or could it be something else still?

And since i dont have a vag com, i tried to read my o2 sensors with my obd2 tool. it cant read actual A/F ratio but it can read the voltage. it reads .890 volts at idle is this normal?

i went through more than half a tank in 100 miles driving conservatively.

 

The 02 voltage should bounce around a bit but should be right around 1.00 at idle.

What block are you reading and what are your block 032 readings with the engine off and key on?

 

mike he is doing all this with a obd reader... he said he doesn't have vagcom

 

Well then I guess he needs to get a Vagcom doesn't he? lol

All those things are good for is reading codes. If he really wants to know what the car is doing to fix any issues he is going to need a vagcom.

 

lol sorry i dont have one as of yet but ill be going to someone who has one in the next few days.

i fully hooked up the n75. i know the psi is supposed to be set to 20psi. with the n75 i only spike 17ish on 2nd gear and 15psi on any other gear. how ever with my mbc i could get to 20psi no problem. Could the n75 be bad? or even bad enough to not make a difference wether the harness is plugged in or not? or do i need to clear a code for not having the n75 in the first place with a vag com first?

 

i spike over 20.... and settle to 18-20.... so you have an issue

 

^ do you run yours on the stock n75?

what controls the boost, i know its the n75 but does the map sensor have anything to do with it?
