blobak Member 75 Member For: 18y 4m 1d Gender: Male Location: them there hills Posted 09/10/13 10:18 PM Share Posted 09/10/13 10:18 PM 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?

Ie welding, any other electrical work?I've heard plenty of ECU's getting fried when the mechanic didn't disconnect neg lead on battery before working on it, but as for tuning only, nope, you'd be the first.....

Adam Here since the start... Lifetime Members 10,282 Member For: 21y 7m Gender: Male Location: Victoria Posted 12/10/13 06:36 AM Share Posted 12/10/13 06:36 AM Why are you assuming the PCM got a spike? Maybe it has just developed a problem firmly in the sh*t happens category. Sometimes things just stop working. Link to comment Share on other sites More sharing options...
