Anyone got the word yet on how they are working?

Sorry if I missed it, been away for a week.

Mine is still moving but not as bad as before. It only moves back and forth between 3-4 numbers.

Are you using the new transducer on your Commander?

AlCorr

YES, I'm using the new transducer on my Commander.

gosh AlCorr, I have been waiting on your report. What numbers are you seeing?

AlCorr

At idle, 10,11,12,13,14,10,11,12,13,14,10,11,12,13,14,etc. it never stops. When driving, something the same, moving from low to high between 4 or 5 numbers, but never dropping to zero like it did before. I made a call to Quad customer support and was told there will be a update for the Commander to slow it down. Looks like very few of us are having this problem, figures, I'd get one that's defective.

anyone know if the quadzilla mpg module is a pressure box or a timeing box???

Well it plugs into the rail pressure sensor and the MAP sensor, so it probably does a little of both. It may not increase the highest pressure it may just increase pressure sooner in the RPM range.

ihave one and i havent noticed any diference in pres from stock but it does increase power a bit as i notice a slight dif on the camander from level 0 to 1 which is mpg tune on the x2 i have

Any word on the update for the Commander?

AlCorr

File Name: Commander Control System ver 1.4.9
UPDATED: 2/3/09
Software Version: 1.4.9

Features:
Adds support for Quadzilla XZT+ modules
Adds support for Fuel Pressure Transducer 0-100psi

OK, I just installed the update in my Commander, I won't be able to put my Commander back in my truck till late tonight, I'll let you know if it helps tomorrow.

i thought the commander had to be sent in for some kind of update to work with the transducer. is that not the case? (if so, sweet!)

CTD NUT

That is still the case if you choose to go the transducer route for measuring FP. It seems Quad came out with a software update after the fact that you can dowload yourself that is supposed to help stabilize the pressure readings and prevent the reading from constantly fluctuating (annoying) - but that is all this particular update does.

Did the update fix your fuel pressure reading???

AlCorr

NO, The update slowed it down a bit, but it is still continually moving back and forth between 3,4 numbers. I'm just felling sad about this whole thing.

Sixpack73

well it IS digital, and small fluctuations are going to be normal, even on an analog guage. it would be more noticable on a digital display though. the question is how much fluctuation are you seeing and are you sure there's no problems with the regulator or bypass valve, fuel lines, etc?
