i picked up my car today here are the old numbers before ems and the new ones. let me know what you think, v-tec is at 4200rpms, stock pulley but im going to a 4.25 pulley in 2 weeks.

 

Dropping the Vtec point made a big difference. 40+ hp is a nice gain. How much boost was it making?

 

wow af/r is high!

 

Was high. Looks good with teh ems now.


I'm having simliar high afr's with my stock comptech.....


Looks like vortec's black box is a better solution than comptech's....


Xviper gets a very level 12-12.5 afr at WOT from my understanding.

 

making about 5.6lbs of boost, im going to a 4.25" pulley soon, should be at almost 8lbs of boost.
also with my ems can i change out my exhaust without doing anything to the ems? i dont want to mess up anythibng but i want to change out my exhaust for something with more sound.

 

If you change exhaust you will most likely have to re-tune. You'll want to check the A/F at the very least.

 

Looking good man

 

If 11.5-12.5 are ideal then why isnt my a/f just a perfect flat or close line? why are those spikes in there? Im an EMS newbie. thanks

at WOT im at about 10.2-12 when i lift it goes off the UEGO scale which goes up to 17/1 ratio, is this normal?

 

i have the same numbers.
Am also curious.
