2 bar map sensor Options

[jesterwr217]

ok im currently using check valves and im wondering what i have to do to put a 2 bar map sensor on just take out the map sensor and put the new one in and replace the check valves with regular vac hosing? and i have an safc 2 what do i need to change on it so my ecu isnt all screwed up? and if anyone has a link to somewhere i can buy one that would be great

im using the 2nd gen mr2
im just adjusting the fuel at idle i havnt driven it yet but when i added the fuel it idled smoothly but my wideband is all the way red??

if your "wideband" dont give you an exact A/F ratio #, then its NOT a wideband.
those "lightshow" regular o2 sensors are pretty much usless for tuning.

its been perfect since i put it in and it IS a wideband its the aem wideband uego

well, what is the number your getting at idle?

you SHOULD be lean under lo-throttle, off boost conditions.
as your approaching boost, and into boost, you should be 11.5:1
everywhere off boost you wanna be between 14-15:1

b4 i put the new map in it was at 15 now its pegged out past 18

your running supra injectors, right?
315cc, not quite as big as they should be to jive 100% with the 2 bar map is my guess.
see, with the 2 bar map, its basicly a balancing act of getting in big enough injectors to have pleanty of fuel up top, while still being able to tune out the richness you normally get in the low end.
are you using the stock FPR ect?
i never had the wideband sensor in when i had the 315cc injectors in my car, so i cant tell ya how lean i was at idle, but at the dyno i used one, and with how lean i was everywhere else, including in boost ( i was as lean as 17:1 in boost before tuning)
