Well I have finally aquired all my tuneing stuff. I have been reading all the artivles under the 165 heading. Thing is ...they all apply to the $32b code ...not mine($6E). I understand what has to happen . Datalogg the car and , make changes to keep the BLM's at 128ish and the A/F ratio to 14.7ish and , keep these values where I want them ...at different loads. I just don't know which tables to manipulate . All the other articles had a few tables I didn't have in mine . SO I have left everythnig alone so far . It starts fine ...idles good too . Funny thing is ....it's the stock 305 1989 prom. I want to dial it in better so I am starting with a manual tranny Corvette bin. to input to the ECM Then maybe make a cam change for more of a challenge.


I am not asking for values . I figure I will just make changes proportionately to the respective values ..... i. e if the BLM's are 13% off in a certian range ....I will make changes to the fill in the blank table in the same respect .

Hopefully I did make some sense . Thanx for your time

Thanx alot man ! Is that all I really should be messing with. I went into constants injectors are set to 22.4lbs . It is a manual bin from acorvette . SO I am assumeing stuff like fuel curves and stuff won't be a radical thing. So I will leave them alone maybe . So ...the MAF tables are all I need to mess with eh ? This is gonna be easy then if I don't need to touch anything else.


again thanx alot

Do you have aluminum heads? If not I'd look at importing the iron L98 spark tables (main, coolant, PE, etc.). Also, modify the "Max MAF vs RPM" table, scale it by like 2 to give yourself some room.

thanx a bunch . I have the 083 Iron castings . I see why you would say import the tables from the iron head prom . But I am running 10:1 on this motor. SO would it still be okay to keep the more aggresive spark curves ,etc from the vette bin ?



I scaled that table ...but mine was called "MASS airflo vs RPM " This is the one I did it too . I highlited all the values ....then scaled them to 2 . She pegs out at 255 gm/s at like 2800 rpm . according to the table . Does this sound right ?


Thanx agian ...I am still just kinda learning the lingo so bear with me lol

Sorry for the whoreing here .

Now I see them other tables you mentioend . It's all starting to make a bit more sense . Can someone posibly name a nice cast iron head prom ? Plus I am running a manual . So if that matters .
