I'm new to this whole thing and was going off stuff I have read so bare with me.
CID is 204 injectors around 30ish and maf all crazy because I halved those because I though I was not suppposed to have over 2k on the maf. So I scaled everything by half. I would greatly apreciate a little guidance. I can give you all the information needed for a basic start point.
I went back to a stock A9L tune and changed the following:
1. Changed CID to 408
2. Changed injectors high/low to 62
3. Changed injector offset to the 60# setting from EA
4. Input the 30# MAF transfer from EA
5. Input injector timing that was calculated from EA based off my cam and rocker ratio.
6. I put 1.00 for lambda values all throught for base OL to tune the MAF.
7. I ran the car and adjusted the MAF based off of lambda values recorded by BE and imputed into EA
Is this a correct approach or am I way off. I really apreciate the help you guys are giving me so far.
I'm not sure what you mean by this. You are on the right track but all you need to do it set Z_OLSW to force OL (which you did in the tune you posted earlier). Then clear your KAMRFs using Z_KAMCLR (be sure to set it back to normal after you clear them). Then set Z_ADPSW to disable (again you did this in your earlier tune). Then just log your driving for a while. I usually try to get in a good 20 mile drive varying the driving style. Your base OL table appeared to be unchanged in your earlier tune. You can leave it that way or you can change it (I would change it.) I usually replace all the the values under 65% load with 14.65. Then as you get above 65%, you can start richening it up until you are at about 12.6 at WOT and loads above 80%.
After you do that, run the log through EA. Be sure you have the filters set to eliminate accel enrichment and transient fuel. Also be sure you have it set to only use OL. Once you do that two or three times, you should get your MAF dialed in pretty good. Make sure your new MAF curve is a smooth curve. If you look at the one you posted in you early tune, it was far from smooth and that will give you all kinds of headaches. You will probably max the ProM out at WOT so you may need to look at getting a new one.
