it is a kevin L. rebuild. i have an safc-II hooked up to the press sens, large sp, i think kevin did tb mod to, 720 sec, ported wg, 6/6.5 psi boost, cone intake and soon to be new tid, gutted exhaust (prev owner), walbro 255, and emissions removed. i am running rich and i was wanting to know what would be a safe amount to tune it down to? just to save a little gas. i know that i should have it tuned but there isn't any tuners that i know of around me. i just want some thing safe and conservative for right now.

 

why dont you ask around schucks/napa and try to find out if there is a dyno around somewhere. sometimes there is at colleges, and if there isnt, you can buy a wideband o2 sensor with datalogging, and tune the safc according to the data logged by your wideband, they are like 300 something of rx7.com or rx7store.com or something like that (i think)
hope this helps.

 

Do a search for SAFC, there's a list of different settings people are using.

 

i put mine on a dyno today... tuned to 11:1 under full boost. Doing the math can get you close but everyone car will run a little different. So get it on a dyno.

i set my changeover from lo to hi map at 7psi. tuned the low map after 4k to stock levels and on the high map ended up with -2% from 4k on.

I have 680cc secondaries and should have enough fuel for like ~270hp... ran 235hp and and using all but 2% of the fuel. so everyones car is different even with the same setup.

 

i have searched and have not found anything that is helpful. DYNO that does tunning???? anywhere close to where i live? NOT that i know of. the closeest one that i knew off and i think it closed down was almost 2hrs away. wich i dont mind driving buy i am not finiished modding the car. like i said i would just like some SAFE conservative settings.

 

the a/f results from the dyno run will allow you to tune the car with feedback of what its doing.

 

Yea I don't think you can blindly tune it. I mean its just not safe. Your better off either leaving it the way it is, getting it on the dyno, or getting a wideband.

 

how much could i tune down the 720s to get them to stock levels?

 

You might see if a local auto store can rent a wideband...

 

i have never heard of that one.

 

if you do not understand a/f ratios, what a wideband is, and dont know what a dyno is then dont even think about tuning your car by your self. find someone who knows what they are doing... and no that dosnet mean some random honda kid.
