Re: 4-Sale 341 WHP 99 Civic Si
Interested, however..
When does it seem that the car is cutting out? (ie. accelerating, decelerating, etc. or completely sporadic)
This "transmission knock", the only times I've ever heard a knock from a transmission was when there were missing gears as in not available/working, are you certain it's coming from the transmission?
Dyno sheet. Is one available? Because your torque is slightly higher (but not impossible) than what I would expect given your HP (by 15-20 ft/lb), almost as though there is a very aggressive timing on the tune, unless you have an EGT gauge you would never see the damage that a high timing will do to cylinders unfortunately so I'm concerned with this.

The car only cuts out when the motor is at operating temp., and when you push in the clutch while driving at any speed. It doesnt happen all the time but enough to be annoying. It never happens while accelerating and when it does cut off, it doesnt sputter or anything just cuts off. I dont think its the tune since it got tuned less than 600 miles ago.
The trans. problem is another weird one. I had the trans replaced about 500 miles ago and at the same time, I had a LSD installed. I am just about postive that the noise is coming from the trans. The knock only happens under deceleraton, and when the car is idling without the clutch pushed in. When you push the clutch in at a idle, the knocking goes away. The trans had 35k-40k when it was installed.
By the way the tune, trans work was all done by Millinium(spelling??) Racing Development, and I have talked to them about these problems. Just dont have any money right now to get them fixed.
I do have a dyno sheet. I made that power when it was 96 degrees outside. Hot ass day. I dont think the tune was too aggressive. I told them to give me as much power as safely as possible. I could only hope they didnt go above what I asked. No EGT gauge.

OBX limited slip differential (installed about 500 miles ago)
I'll PM you to get directions, but, letting you know I'm doing this incase you dont get the PM. (redundancy type of deal)
