Another Camshaft devation question

[The Radium King]

deviation should stay constant and only change when the cams roll over at 4k rpm, at which point it should jump significantly to say 25. did you reve over 4k rpm and still get no movement?

[The Radium King]

if you think your cams are not rolling over, you can manually trigger them with the durametric. if you go to activations there is an activation button for each bank. you should be able to watch your actual values when you do this, so that you can see the deviation hop when the cams are activated by the durametric (there should also be an audible change in rpm).

if nothing is happening then perhaps your solenoids are shot. regardless, a deviation of 9 at idle is out of spec, where spec is defined as within 4 or within 6 depending on how dr. ing is feeling (initially it was 4, but was expanded to 6; uncertain if this is tied to engine type or just a change in standards).

Thanks for the information...very much appreciated.

After a nice warm up this morning I hooked the car back up- I activated bank 1 and 2 cams- and got a nice pull down from each just at idle. The car did not die but dropped significantly and returned after I stopped.

I then pulled cam 1 and 2 up and got the same deviation as indicated (1 @ "0" and 2 @ "- 9") then I attempted to activate the cam banks while watching the deviation- each time I tried it locked the program up and I had to get completely out of the program and re-start to get any communication??

I took the car for a drive again while monitoring the deviation on both cams- Got it out on the highway and reached the + 4k RPM mark numerous times with no fluctuation whatsoever?

I am going to remove the software from my computer and reload and try again tomorrow? Any suggestions?

Oh...all is not lost- I spent the entire day in the car- 80 degree day......... what deviation? who cares!! Thanks again!

yeah, the software can get glitchy. i've found durametric very responsive and if you contact them you can get the durametric software to log the glitch and email the info to them for troubleshooting.

when driving, can you feel a surge of power at around 4k rpm when the cams roll over?

Thanks again for the input Radium- your expertise/advice is appreciated.

Yes, I can certainly feel some changes at/or around 4k rpms. Feels like a power band in a dirt bike.

I removed and re-installed the software- hooked things up this morning. (Deviation: Cam 1- "0" Cam 2- "-8") so I actually seen some movement. I again attempted to activate the cam banks with the only result being software lock-up.

Took the car for a little more aggressive drive after warm up and getting communication going on the software again- Nothing- Rock solid at the above numbers? I pushed 6k rpm through the gears numerous times and got nothing?

This is my plan- Call Durametric tomorrow see if they have any ideas- did not get a chance to today.
