We bought a AMC 360 with a Holley projection 4di system on it. Opened the ECU up and the chip is the original so it requires us to use the 2.1 software. I finally found a win 95 laptop to be able to hook up to the ECU tonight. We have got the jeep started without the laptop but are having a few issues and wondering where to start. Turn the key on-> fuel pump kicks on-> turn the key to start-> motor cranks but no fuel from injectors. but if you whack the gas to wide open for a second the injectors gives the motor a quick shot and then will fire right up. (for Tach signal I have the yellow wire tied into the tach output on our GM style HEI). once the motor is up and running its idles up to around 2000rpm and that is with the idle screw threaded all the way out. If i slowly put my finger over the IAC port it will idle down, but once my finger is removed it goes right back up to 2,000, I did install a new oxygen sensor into the headers. When we bought the motor it seem to run well and all we did was pull the motor down and have the heads re-done and then new gaskets through out. We have not had this hooked up to a laptop at all and not sure what it will show or help me with. I have a friend coming over this weekend to help, he has never worked with this system but he is a good ASE mechanic and avid drag racer so I hope the info the software spits out is something he can understand.
Motor is nothing fancy AMC 360, bored 030 over, fresh stock heads, GM/HEI style ignition, Headman Headers , TH400 Trans.
Thanks for your help in advance, of course we are on a tight time frame supposed to be taking the Jeep to Silver Lake sand dunes in a week, and I really want to keep the injection vs going backwards and throwing a carb on it.
