map richening question
 

ok so I have a question about richening a map and cranking up my boost
the map I have is tuned for about 11.5 - af ratio im running 10 psi
I want to try running 13 psi
can I just richen the map and crank up my boost (if so is there a rule of thumb of how much % I have to richen per psi) or do I have to ---- with something else

im also wondering if I retard my timing and crank up the boost will that affect my idle and how my car runs or will I be able to squeeze a couple of horse power out of it (id try this my self but its raining and all I do is spin tires)

my set up is a d15b7, 14b, 450 cc injectors 10psi at the moment

search still dosent work

no

Re: map richening question
 

k thx
is there any thing I can do to my map or do I have to get a new one

Re: map richening question
 

you dont just "get a new map" you have to retune.

Re: map richening question
 

I know that
but if I crank up the fuel in the 11 psi column then technically I could run more boost at WOT
I can borrow a y-band from a buddy to check af ratio

oh and I meant the timing retard in the distributor not map

the hole point of this is im doing a z6 swap during x-mas and I want to ---- around with the map and learn how to tune/crank up boost on this engine
that way if I blow it or ---- something up I wont care too much it will just be a bitch to get to work

Re: map richening question
 

what is a y-band?


get a WIDEband, then you can start tuning. or if you wana be a crazy ------, go ahead and make changes in the dark.

Re: map richening question
 

I think what he is saying that he wants to run boost past the stock MAP sensor's reading ability, and he wants to richen the max boost settings because he thinks the settings will carry over into the next boost columns....

Doesn't work like that....if you boost past the 11psi column then you can set anouther column to run everything 11+.
I assume you are using crome? You may want to look into using a GM map if you are going 13+ for any length of time.

Re: map richening question
 

yep, get 3 bar map ... and if you up boost just try to get a good AF to all maps... that's what a tuner try to get when tune a car.. to get a very good AF runing to a very good timing :l

Re: map richening question
 

im using uberdata
yes thats what I wanted to do
and my bad I meant WIDE BAND

ok so if I go to 2 bar and the column goes up to 14.7 psi will that be enough
should I richen it or just try it?

Re: map richening question
 

as far as i know .. runing with 2.5bar map .. you would can to tune it up to around 20-22 psi
