@zeneffect I was unabke to connect the the ecu at all since this happened to me. After I swapped that parts in the op I determined the ecu was not coming out of safe mode no matter what I did. So I thought maybe I could connect to it with and take it out of safe mode but was unable to ever connect to the ecu at all with miltiple programs/computers/people trying. Just wouldnt talk to anything. I have a core now and can try swapping the boards but after all that do you think the tune would be lost anyway? Just wondering. Also without a tune on the ecu would it not prime the fuel pump at all?
That could mean a couple things try to follow my randomness...
One- the tune the car had at the time of breakdown could have been corrupted causing the breakdown...
Two- the car still started up but in safe mode because the ecu still had a tune, just one that was corrupted.
Three- after some time of the ecu being out of the car ajd the battery backup being off the board maybe somehow the board kicked the tune altogether? Is that possible?
Because after I put it back together for the last time 3 days ago and tried another 3rd laptop to connect we found that the fuel pump didnt prime. Thank baby jeebus for liquid filled fuel pressure guages because that would have stumped me for at least another hour or two. ..
Any of this ring true at all? Even if I get the car running either way id like to know what really happened.
