I did find some time and put on the new throttle body and did some reprograming.  tryed to develop a 3d equation from info i gathered for my VE table.  and i also put all the wires in a nice harnes.  took it out today for a little ride on some trailes.  gotta say worked way way way better then the old carb that i had on it!.  but it still needs some fine tunning of the code to make it perfect.  i tryed using the serout command so i could see what is going on inside the ecu as its running.  i programed a little monitoring program in PERL, of all langueges, to read the serial port and desifer the infromation and then show it on the screen.  for some resone i could only run the sx serout command at a maximum but rate of 38400 witch is kindof slow. but any faster then i would get data corruption.  probably bad cables im using,  two 6 foot serial cables.  i had to make the sx only send one byte every engine revoution.  if i were to make it send too much then it would take to long and then the sx wouldnt be ready to read the hall effect sensor. 

havent made use of the little eeprom that is on the board yet.  not sure how i want to go around makeing use of it.  maby eventualy use it to store the variables so they can be changed with out haveing to pull the crystal and used the sx-key.  i think that ill just used the equation to get my VE, i think it would be faster then sending a comand to the eeprom then haveing it send back the info.

The IC's im useing to drive the injectors work fine for my application,  did not lean out at high rpm and they just got a little warm while i was driving.  i have a waterproof plastic box that the pcb board is designed to fit perfectly in.  i think what i can do to keep it cool is do what they sometimes do with prossesors and heatpipes.  i could just have 2 heat sinks on for the inside of the box and the other for the out side. and have them connect to each other with some copper and make sure that i seal the hole in the plastic.  but right now everything runs fine with no heat sinks at all.  but once its inclosed im sure it will start to warm up.
