Loopey Idle

[03 D-max]

i'm not sure why but almost every tune i load into my truck i end up with a loopey idle even ones that i got from other people. i was wondering if a loopey idle is bad for my truck? i dont mind it aslong as its not doing any long term damage. i have even set all of my below 1800rpm tables back to stock and still get it... is it just my truck?

does it do it on the stock tune ? i know the tunes i sent dont do it on my truck . i would log it look at cammand pressure , actual pressure , pw , mm3 and then if your getting what your cammanding and there are no differences , check the stock tune log it and compare . when i started tuning fuel pressure tables did this to me when i screwed them up and pw .

on edit might not hurt to check your balance rates too .

it doesnt do it on the stock tune but the tunes you sent me do it when i have any load on it like if i have it in gear and am not moving it will do it...

i will try logging everything and see whats going on

how do i do this is it a PID

Any CEL? rail valve current table adjust might help. LB7's do not like more than 20MPa at idle IIRC Good luck

Mine lopes when I first start it and then smooths out after 30-40 seconds.

Yes you can do a pid under the display table in scanner if you need a config file i have one in the hp tuners forum or i can email it for ya but it best to learn to set your pids up .

apperently my truck is very sensitive to pulse width at idle pressure i had to go through all my tunes and change the pw slightly and now back to normal

thanks everyone for all your help:hug:
