single shots wont idle
needing some help in a bad way, recently put a set of 180cc%100 nozzle single shots in a 02 SD, truck runs great other than im having an issue getting it to idle, as soon as she kicks off she starts loping real hard and wont stablize unless you feather the throttle a little, once its stabilized it idles just fine , did a data log and it looks like its bouncing from 100 to 0 on mass fuel desired, just looking for some direction if yall wouldnt mind :woot:

yessir,I also got a few base files from you guys for those injectors, i spent about 8 hours the other day tweaking it and data logging and just cant seem to nail it on the head, not sure if i need too look at duty cycle or my pulse width
|
Are you running the 180/100 files? Or the standard files for the stock injectors?
The 180/100 files should actually idle pretty well. We've used those for many years with very few issues. |
ive tried all three that i got and no change, truck came in for injectors and cups but started and ran just fine
|
ive also put some miles on the truck as well to rule out air in the system
|
So the next question is... How does it run on the standard Hydra calibrations?
|
EVEN HARDER TO START
|
as soon as it sees enough rpm to fire off it drops duty cycle down to almost nothing and you have to play with the throttle to get it to stay running, after that it idles fine but if you hold it too the floor and let off the rpm drops down and then dies, watching the data log it shows the duty cycle try too pick back up after the rpm and icp have already dropped down too far to stay running
