GM dis (ecotech) question
I'm trying to run an eco tech with the dis setup. The motor starts and idles well, but there is no timing control from the ms. If I scope the bypass line and the timing control line, they look identical. There are pulses that have the same shape, frequency and phasing. The bypass line should just go to 5 volts after startup. I am using 24s9 code. Is there a known problem with this code and GM dis (or hei) ?

more info
I useda two channel scope to look at the reference pulse, and the est signal. I do see a phase shift between the two. That would indicate that the timing control portion is working ok. When I scope the bypass line, It is exactly like the est line. I have scoped both est and bypass outputs right at the cpu pins , and they are identical there also. Later today,I may reflash to the latest code to see if that helps.
