why not set the last light at 8k or 8.2k? thats redline/fuel cutoff
Because by the time the red light comes on, the engine would be bouncing off the rev limiter and choking (I have a 2002 BTW, fuel cut is at 7800RPM)
Red comes on at 7K because if it lights at 7K, I still have about 800 RPM to do something about it (IE shift the tranny or let off the gas pedal) I consider 7K my danger zone, if the motor is revving too long at that speed, it's not the best for the engine's health anyways. I used to have it set so the first light would come on at 5K and the two ambers and red would light in sequence through lift, but in the long run I found my current settings work best for my driving habits.
For those that asked, I'll try to take some sound clips of the exhaust in the near future. It's pretty loud with the silencer removed, but with the silencer installed, it's nice and mellow tone.
BTW, I also purchased a beltronics FX1 accelerometer. I've been messing with it a bit, getting it dialed in properly. I'll be posting a guide soon on how to set up a Vector FX1 or FX2 for the celica soon. unfortunately, for truly accurate readings from this unit, I need to get a baseline dyno of my car to calculate HP correction.
Right now I've got it set up to where it measures crank HP pretty close, the invidia seems to be good for an extra 3+ HP to the wheels when the silencer is in, closer to 5 or 7 HP with the silencer out (this is just with the exhaust, and a stock Intake
system w/butterfly still in; I expect these numbers to jump up a bit once I put on the K&N Short Ram
So stay tuned for new pics, updates and info; it's on the way.
