General SAFC II settings?

[mattspyder]

alright i was told that i need to turn my fuel injectors down with my safc II.
i have a t04b vtrim. fic 650cc. and a 190 lph pump! what might be some good settings to work off of for those injectors??

"you want to use baseline corrections for fuel injectors. If you have 450's, leave both tables at zero. If you have 550's, put them around -10%. If you have 660's, usually around -18% would be a fine starting point. If you have a hacked MAS, then you will want to use about 5% MORE than these values."

found in the Frequently Answered DSM Questions

kpt4321 (my hero) says that a good baseline correction setting for 650's is about -18% across the boards and then tune from there. This is his bad ass guide. Good Luck.

I am courious as to where kpt4321 came up with those numbers.

The normal compensation is

(stock injector size / new injector size) - 1 = baseline correction value


Example:

(450 - 650 ) - 1 = -31%

With 650's my high setting were around -34.

I would suggest against that setup. I purchased my Palm m105 off of ebay for $16 (shipping included). Get the software from www.pocketlogger.com for $125. You saved money and got what I feel is better software. But that's just my 2 cents.

Until getting professional tune with good air/fuel measurements be careful. I have seen a bunch of friends lean their cars out doing stuff like that. Me on the other hand had mine so rich on the way to get it tuned the back of my car was black when we got there Rather have it rich and safe than lean and BOOOOOOOOOOOOOOOOOOM.

I think road race has some settings on their site that were off custo cars. Maybe a good baseline but my suggestion is just go a little richer (less negative) until tuning so you don't hurt the motor.
