1. Not mine. Check to see that everything is connected correctly, most importantly your amp which is located right above the sub.

2. Your DSI cable might be fine, but the motor may have gone bad. Your best bet is to take it in to the dealer.

Along this same line, how can I tell if the DSI is shifting? I've never been able to tell, and think this would be valid information for this post.
thanks

You could have someone rev the car and you con just look at it and see it move. Or if you have an aftermarket intake, or even just remove the intake resonator, when you are driving and hit about 5800rpms, you should notice a slight change in noise.

I have had the same comment about the stereo. The reason being is that I just bought a 2003 Foci for my wife with the Audiophile system and here sound is crystal clear and significantly sounds better. I chalk it up to the music I play, lots of metal.

No comment on the DSI cable as I can here mine switch some of the time but I have a CAI.

When I had my JRSC put in, the mechanic pointed out something interesting to me about my DSI. He said there was a little plastic part on it that was broken that was preventing the DSI from opening up. So you might want to check the functionality of yours...see if its actually working.

The funny thing about it is that the car dyno'd at 150HP with the broken DSI. No other mods were on it aside from the drop-in K&N air filter.

dazednconfused75 and aychseven - good call. I could see the DSI (or at least the cable) switching when I reved the engine via accel cable/throttle body. The cable moved, and it looked tight, but I can't tell that it's moving the whole assembly. I assume it is, as the cable would probably be hanging loose if it weren't.

Hey guys are you saying that you can have some one rev your car in N and look in the engine bay and see the dsi cable move? I thought the switch took load on the car into consideration, and would not switch when in N. Well, let me know cause I would like to check this out.

I saw it switch no more than two hours ago infra. You can definitely see it happen. They weren't lying.

to check the dsi look at the cable with the car shut off,it should be loose which is the short runner pos. then start the car and check the cable,it should be pulled tight which is the long runner pos.

Thats cool man! I didnt mean to make it sound as if I thought they were lying. It was said around here a while ago that you could not see the switch with the car in N, I am gonna check this out first thing in the morning....SWEET!

The DSI manifold goes to the "short intake runner" position by default if the linkage breaks or if the cable breaks or is disconnected. The short intake position is where peak horsepower occurs - 7,000 RPM. So your car would show peak dyno hp even if the DSI were disabled.

Simple test:

First, gain access to the motor (remove the fender liner, bumper, etc.) You will see a plug on top of the box (in front of drivers front tire, BTW). In there is a harness with I beleive 5 wires. A green/ white, white/ red and two black/ whites. The fifth wire is white/black I THINK. Just narrow it down tot he last wire.

Turn the ignition on (do not start the car), and put one end of a wire to ground, strip the 5th wire and touch the ground wire to copper. you will hear the cable move.

I did this when I was playing with my DSI controller...
