2004 AP2
I am looking to slap on a 3" pulley on with stock map sensor and 600cc injectors. I don't want new injectos or 3bar+ map sensor.

With AP2 3" should yield 11psi. You think I can get away with this setup? I am currently at 9psi with my 600cc and OEM map.

 

OEM MAP is only good to 10 psi. Depends on what your tuner says, but your boost tables above 10 will never engage if MAP doesn't read it. Its a tossup. But keep in mind, 11 psi will only be at redline, so maybe....

 

Stock sensor fluctuates enough as it is at moderate boost levels ie 7psi.

 

You can do it. Not ideal but can be done.

 

Aren't you already on some kind of aftermarket ECU option? If so, why not just spend the $80 and set up the scaling for an aftermarket MAP sensor? Won't you be re-tuning your fuel/timing maps once you up to 11 PSI anyway? Setting the scaling for an aftermarket MAP at the same time wouldn't be a big deal.

Sorry, I know, that isn't a simple yes or no answer.

 

I thought new MAP required a COMPLETE retune, partial and WOT

No?

 

Btw I'm on Emanage ultimate.

 

npt sure with eman ult, but with aem ems you can cheat and make it work. of course it wont be perfect, but you can get close. in his case, what he is tryin got accomplish should be fine. just wont have much any room for increase thats all.

 

No.

 

Use a greddy boost sensor and inline motorcycle fuel filter works upto 2 bar and fluctuates no where near as much as stock map.
