Hi Guys, wondering if anyone has had ecu troubles after having car tuned. No I have not used generic tunes. The ecu goes into limp mode intermittently. Have isolated the problem to the ecu, replaced with a second hand one, after a long drawn out process of diagnosing it. The car then retuned and the same shop and using the same xcal3. Am just wondering if this is a regular ocurrance, thought it would be pretty hard to spike these computers?
