mikrad Member 6 Member For: 10y 11m 8d Posted 07/07/14 09:12 PM Author Share Posted 07/07/14 09:12 PM (edited) that's what I said Mark, keep it from Wed morning until Friday arvo if you need to, just make sure it works properly.It sits on an even 14 to 14.5psi until it starts dropping off around 5000rpm, heres the chart Edited 07/07/14 09:20 PM by mikrad Link to comment Share on other sites More sharing options...
Sambo87 Member 26 Member For: 11y 6m 21d Posted 08/07/14 10:04 AM Share Posted 08/07/14 10:04 AM Not to hijack the thread but I have had the same problem. Bf manual 395rwkw. Same circumstance. Cold. High speed/load.It originally was supposed to be on 16psi, boosting up to 22.I took it back, it went back on the dyno. Now it only creeps up to about 20 - Still throwing the p0236 code but much less often..Both times it was tuned it was holding a solid 16psi on the dyno.I will be taking it back and the tuner is expecting me but it is a matter of getting some time to get it there..So you think it is purely a tuning issue?

Z2TT Member 714 Member For: 12y 8m 5d Posted 08/07/14 03:40 PM Share Posted 08/07/14 03:40 PM (edited) Pretty much the 1st Code indicates that the boost pressure is out of normal parameters, 2nd code indicates the specifics in which way it is out of the normal parameters, being it is high. I'd assume this would be pretty common knowledge to all Ford Turbo tuners. The codes are there for safety if something fails and causes the car to overboost. Now I'm not a tuner or guru or anything like that, but from years of working on and modifying cars I'd be interested to know with the Falcon :I'd assume there is an upper limit that the tuner can set, for when an overboost event is detected. If this exists, I would also assume this would normally be set with a margin in place to cater for normal fluctuations due to different conditions or driving, so as not to trigger the codes unless boost is abnormally high.The boost is controlled partially by the boost solenoid so it could be the way the tuner has tuned it perhaps or a combination of other things in the tune that affect how the turbo boosts at different driving conditions.

P0238 is the boost pressure sensor pegging. You can disable them easily for big boost cars, but I wouldn't touch them if you are operating within the limits of the sensors. Did this get sorted?
