if you were to just slap on a wideband without touching the factory tune, how rich would it be once you hit boost? looking for knowledgeable answers thank you.

 

Mine hits about 10.0 on my aem wideband untuned. May be richer then that

 

would also like to know for my evo 9

 

bump for more experience

 

and is it safe to be running this rich under boost?

 

My experience is similar to the poster above. My 2003 dipped to ~9.8 or so at 6800 rpm and up on the stock tune, and no boost leaks. I measured with an Innovate LM2.

 

hmm i seem to be getting the same, i guess thats normal then. it just seems TOO rich for my taste, plus my wallet is getting thinner

 

10.0 is very rich. Getting close to washing down cylinders rich. Definitely need to lean it out

 

waiting for my evoscan wire to come in the mail, its been like a month.

 

Stock tune runs very rich. It helps keep the cat happy, as well as keep the motor together with the crazy amount of timing on the stock map.

 

If I look long and hard I can find you a data log from my Zietronix unit, but.... from memory its very low 10's ~ 10.0-10.2

 

is it safe to be going WOT like this?

 

If it's a factory stock tune evo they all run pig rich and crazy timing down low people run 87 octane in them and put the wrong plugs and floor it all the time and they don't blow up. I think it's safe to floor it lol.

 

Yeah dude, the factory tune is fine, not best, but fine. They are responsible for durability and warranty of the vehicle, it would not be in their best interest to give you an 'unsafe' tune.
