#4969, "tuning idle...msnsE seqential"


          

the open time is set to .65ms. heres a shot with wue and ase off, its steady for a bit then gets a little lumpy. I can see the rpm gets a little lumpy, is this noise?
it seems the rpm jumps and dips but for the most part everything else stays steady...

Can i force an IAC step number while the engines running? like if its at 10 steps, and i want to add air, can i add steps and burn that table while engines running?

any ideas on how to smooth it out?

That looks surprisingly stable for being sequential. Of course it will be more stable with it, its just getting it tuned to do so thats a pain. Looks good to me though.

How did you get Vacuum log on there?? Dont think mine has that..

i have the licensed version of MLV, it was an option on the left hand side lol..
it feels good, but u can see some spikes and dips. you can feel those lol..heres some more food for thought..

played with VE, its sorta better,but not quite where i think it should be i guess


then i plugged in my fans, they are grounded from a diff source then the sensors, when i did this idle went up 200 -300 rpm, my vac dropped to -22 in hg or more! wtf, but idle rpm was crazy smooth? then i noticed cranking gettin harder, ie batt volts going down, i didnt have this prob before, it seems only when fans plugged in it kills the batter..

what gives???
