snafu69 New Member 9 Member For: 9y 8m 7d Posted 16/03/15 04:18 AM Share Posted 16/03/15 04:18 AM (edited) I have a BFxr6 Turbo with a HPF Custom Tune at 298.6 kw at the Wheels, Since getting this done I have had a recurring error on the Dashboard with three or more error lights and the speedo will error out and drop to zero. This only happens under hard acceleration under boost. It has a custom exhaust and dump pipe from Performance exhausts with seimens 60lb injectors opened up airflow and a high volume fuel pump. Ford blamed this on a timing chain issue which I have had the chain and guides replaced the guide was broken no improvement. ECU has been replaced and reflashed HPF had it for 2 days on a dyno and couldn't find the cause of the fault though they believe it could be in the CAN bus (may as well say yea theres a fault in the car ) they spent the day pulling on various parts of the loom to no avail. A auto elec had it for a full day and said take it to ford lol .. Ford suggested I goto HPF...... PLEASE HELP !!! lol please see attatched Video of fault happening I had a friend said he had a similar problem with his 370kw tune and it was to do with the tune and possible to fix it via altering the tune..please check out the clip and any advice would be appreciatedthanks Edited 16/03/15 04:27 AM by Ralph Wiggum Link to comment Share on other sites More sharing options...

Do it do it free reving only or under load well? Any other symptoms (ie loss of power)How old is the battery? Has it been tested properly?Fault codes?

snafu69 New Member 9 Member For: 9y 8m 7d Posted 16/03/15 08:52 AM Author Share Posted 16/03/15 08:52 AM haven't been able to drive it with a stock tune as the ecu errors out with overboost due to the big dump pipe. Not temp based will do it all day long anytime its under heavy acceleration and it will do it all through therev range the engine actually sounds like it misfires when this happens. Batteries I was running Duel Optima Yellow tops with 1550 total cca even gone back to a heavyduty brand new battery and taken the fuse out of the boot mounted batteryto try and eliminate this .. The earth strap between chassis and motor has been checked and tested was a little loose but didn't improve things. TBH I don't think I have gotten it to do it just revving not under load something I can try later tonightwhen I go out away from houses lol.
