ms-pnp weird inj behavior
 

Long story short mspnp is in fired up fine was doing some light drives and noticed I was way rich but not only that but the wideband was fluctuating from 14 to 10 wildly then it would be fine for awhile...

I follow the problem to the pulse width and duty cycle gauges which for some reason are steady one minute (as steady as they get atleast varying only by points) then jumping around like fucking crazy, up from 5 to 10percent the next!

It doesn't seem to do it more or less during cruise or accel but it is much more noticeable during accel,obviously.

During mild accel duty cycles were going from 20 to 30per and pulse width was also jumping ten or so points.

The ve table is smoothed out abit as I thought it might have been going from one cell to another and they were to large of intervals but that's not the case either.

Injectors are rc370cc and have been in for a long time with
Any ideas?

how smooth is your VE map? if there is large change between the cells the situation you describe can occur.

EDIT just read the full post and maybe posting your msq and a log will help?

Well after a 3hr drive this morning to work it dawned on me.

The map reading was moving alittle to much then I remembered that my leakdown test showed a 50per leak in cylinder 2 out the intake valve and 35per out cylinder 3 intake valve.

Soooo with all this pressure heading back into the intake no wonder the map is jumping and thus the injectors think she's getting more air lol.

Needless to say it sucks because the right way to fix it is a rebuild, but I'm going to try a restrictor to even out the readings, hopefully that woll work for the time being.
