Thank you very much for your attention, the question is quick and perhaps silly for many, but I am starting to work on an evolution IV GSR and I have a problem with the OEM ECU because it seems to have burned and that's why. It doesn't work and it doesn't start, but I found an ECU from an eclipse gst 1995 and with that ECU it does start but it only lasts a few minutes and it turns off and no indicator works, which one do you recommend? Do you think somehow the eclipse gst ecu could work well on the evolution?
