He's running stock tune with stock injectors so I don't think his latency is off.

 

i dont have stock injecties.. i have pte 880's

 

Sorry, forgot you had the 880s but your latency numbers & scaling seemed to be correct.

Can you log fuel trims? What do your LTFT look like for idle & cruise. Also, are your STFTs bouncing around when your AFRs are bouncing?

 

K so I was tweaking my latencies today and also logged my LTFT at idle.

It looks like it reads .297 but that doesnt sound right at all...

Also my STFT from my 02 sensor were between +9 and -7

Still when i drive around and am on partial throttle ( like 20% ) in 5th gear, my AFR goes straight to 10.0 and starts driving like crap.

Ive noticed that as long as Im like.. 30% throttle that it seems to run fine... Only when im partialy on ( as if im trying to just maintain speed limits ) does she dip and go SUPER RICH..

 

Sounds like the BOV is opening. Aftermarket?

 

agency power/recirc and its totally cranked down.. as much as it can be. it was leaking air outta the top.. but i opened it up and replaced the o ring..

 

Soo i had a quick thought.... I did have to Replace my throttle body shaft seals, and was wondering if maybe i didnt put the TPS sensor back 100% correctly...

If its not on correctly could it be throwing off my AFR's, making my car REALLY RICH at 2k, which is causeing the bucking?? My spark plugs are ALWAYS black...

 

Also thinking that it may be my ISCV....

For some reason my cars only pulling 4 psi of vacuum at idle.. when i know for sure it should be around 15... sometimes it dips to 15 and is normal, but most of the time it sits at 4psi...

We have done about 3 boost leak tests with NO results... this is why im thinking ISCV is the culprit...

Does this sound right?

 

Is this an 8 or a 9?

 

its an evo 8... an 03
