Same here -- no problems for me either. Could the problem that Ninety-Nine SE-L is having be related to the wiring of the orange and red wires? One is supposed to be switched and the other not -- but some folks, I believe, have wired them both the same way -- thinking that it doesn't matter. Just random thought.

Thats what it sounds like to me (having never touched one). One is the primary power the other is a switched power. The switched one causes the thing to turn on and off. Just like a radio. Of course you can avoid the entire issue by only giving the unit switched power. As long as it does not loose the settings when it looses power then it really should not matter.
AFAIK, there is no way to reset the MSS perse. You have to change the settings that you want to change. See Post #20 in this thread http://www.sr20forum.com/showthread....&highlight=MSS
for a more detailed run through on how to program the MSS.
Good Luck -- it's worth it once you get the MSS working.
thanks guys...
one problem still though > i getting the tps voltage reading on the screen and i have it set for both cam 1&2 to come on and off at 3V but they not coming on ...

Heres what I noticed on the one site that many people to use to wire their MSS(http://www.sr20ve.co.uk/). On his site he has the orange wire and the red wire mixed up. The Orange is supposed to be constant while the red is accessory. Switching these two wires will cause the MSS to stay on after the car is turned off. As previously stated somewhere you do not need constant power for the MSS, it has an eprom and will remember the settings after it is turned off.
thanks guys...

If you set more than one parameter (for example, TPS AND RPM), all the specs have to be met (for example, 3 volts TPS AND 5000 RPM) before the cams will trigger. What other parameters have you set up, if any, and are their specs being met when you expect the cams to activitate?
Sorry guys, couldn`t find right MSS settings for sr16ve. Which revs do I have to set? sr20ve revs doesn`t suit. Now I`m setting 1-5800, 2-6000. Is it correct or I have to set other points? Thanks again!
hey i got a 96 200sx ser
im also doing a sr20ve
i wanted to know with the greddy mss did you the stock ecu or the ve ecu
and did you use your stock harness
thanks

The MSS is independent of the ECU and can be wired to switch your cams to either: 1) replace the switching capability of the VE ECU (which switches the cams at a high engine speed and is not reprogrammable), or 2) to switch your cams if you use a DE ecu.
You should use your original harness in either case. If you use the switching capability of the VE ECU, additional wiring will be needed to connect the ECU to the cam solenoids if you use the original harness.
hey man is there anyway
you can explain what wires i need to add
if i use a greddy mss, the ve ecu, and my stock harness
and also if you know of any other complications
i will encounter while im doing this swaap
i would appreciate it
thanks

Basically, you run constant (fused) 12V to each solenoid and the MSS feeds ground when the proper RPM is reached. The MSS instructions come in Japanese -- so it's a bit hard to figure them out. Ignore the speed wire and hook up the RPM wire to the ECU output to the tach.
Check this thread for how to program the MSS. Also in this thread are some instructions on which wire to tap from the ECU (at least for a B13 -- not sure about others).
