Hey guys. I have what is going to be a stupid question I'm sure. Engines I know, but I am totally ignorant when it comes to the computer stuff. My car is running like crap, so I hooked up my laptop with WINALDL and did some logging. Now I have a big, ugly log file with all kinds of wonderful data, but I have no idea what I am looking at.

Can someone point me in the right direction to learn about all this stuff? I guess my primary concern is - what is "normal"?

Thanks

 

read the stickies on "prom". ask several specific questions.as many as you like. you will get all the answers.

 

Those stickies do not explain anything about what each term in WinALDL stands for. Is there anyone that can breakdown what each term really stands for and it means? (i.e. PROMIDA, PROMIDB, ect.)

 

my first day tune was basically looking at the blms at idle and off idle with car in neutral in driveway. then a drive around neighborhood and again watching the blms populate the rpm/map cells. seems that wide average they populate quicker and more cells. that told me way rich at idle and light cruise. my first burn was setting base pulse width and correcting VE fuel tables in those rich areas. later on i found some lean blms but that was higher rpms/map. lucky for me choke was fine and cold start warm up nice. i did not need to look much at anything else. most tuning is closed loop in winaldl. open loop another matter. winaldl told me nothing about AE or PE. one the fuel tables were optimized the PE was right there per dyno WB02 at 12/1. AE was a bit tougher. another thing i began watching was when CL occurred. also i checked spark counts to see if timing too aggressive or other K issues once i got on gas harder. now i am watching the IAC counts as well. changed nothing. just watching the engine cold start to CL as a function of IAC counts.

 

how do you get winaldl?
