It is rare for these ECU's to fail, however the ECU in my 80 242 DL failed and it was only discovered after checking every wire and ground. One symptom: It was putting 1.5 volts to the O2 sensor instead of 0.5v. A junkyard ECU from an 81 or 82 CI 240 will work, as will any year 240 turbo ECU, except that the latter might make it run a little rich I suppose.
