Back to the research......

That's enough venting, I decided to go back to the research. I had been trying to figure out exactly how the ECM told the ICM to advance or retard the timing, I know it's a 5v PWM signal, but I haven't had the chance to test a running car yet to see exactly what the wave form looks like. I figured once I knew what the wave form looked like and how it changed I might be able to build a box that would modify the signal under boost. Then David A. told me about the Ostrich 2 prom emulator. This thing replaces the prom in the ECM and convinces the ECM that it is a prom. It allows you to adjust the prom program while you are driving! And can be left in place as long as you would like. I'll have to use a program like Tuner Pro RT or others, and I'll have to get a laptop or some other form of computer in the car, and that's where the really neet geek stuff comes in.  Mini Computers as small as the radio in a car, with a 160gb hard drive. I could load all my music onto the hard drive and use a media player and toss my radio all together. I found an in dash monitor with touch screen and it retracts into a radio sized box in the dash. I also found a website that sells LCD screens with and without touchscreen capabilities, these LCD screens are not mounted in a case for more of a custom install. Only problem I was running in to was making sure that the monitor had a compatible signal connection with the pc, most car video monitors just use the old simple RCA cables, the pc has VGA, or DVI and some even have HDMI (hard the find a small monitor with HDMI). Now I'm still back to my original problem, coming up with the money for all the neat stuff I've found.
