Been away with the family for a few weeks, it's sim time again next week so everything stops for that. However more time off after that so the plan is to drop the under trays again, remove the starter and check the knock sensor, also need to check the exhaust as I am pretty certain that the back box is not tight, they could be the cause of the knock I seem to show at times. Check the fuel pressure, I brought a check unit and see why it seems a bit low at full chat.

[CHILL Gone DUTCH]

was it a smooth road surface when you did the runs nick, as this can also give wrong readings and knock

[NickB787]

No not very which could also be part of the knock indications.

[NickB787]

Well first bit of good news the car has not been run since the National and it started first time

 

up on ramps now, I have to go play golf today but will start in ernest tomorrow.

[CHILL Gone DUTCH]

Thumbs up I thought you got list in the simulator

[NickB787]

ok so far so good, I tightened the exhaust back box up as one side was loose, both bolts were hand tight, one the rear I had to replace the nut, nice job, not.. Hope that was the reason for some knock being recorded, wouldn't have helped with 2 polly mounts either.

 

I managed to check the knock sensor without removing the starter motor, it's tail is now at 9.00 o'clock, only problem my torque wrench won't go down to 23nm.. any suggestions?

 

I will do a run as it is and try to check the fuel pressure at the same time.

Hurry up then I can nick your map lol

[NickB787]

one step back, battery light on, 11.5v on scangauge looks like the alternator may have packed up, I was checking the fuel pressure 3.6 bar at idle, notices a slight drop when gently revving the engine need to run it properly at high power though.

 

 

need to sort the non charging first

[NickB787]

I take it I need 100amp unit? what was the best option Autovaux or referb this one?

[leevx2.2]

I have a spare 100amp nick if you want to borrow it

you have a boost referenced fuel system? Standard NA regulator should be 3.8 bar with engine not running/vac tube disconnected from regulator, but about 0.7 lower @ idle.

Pressure + injector settings must be correcty for OBD to run well...

[NickB787]

thanks for the figures will check it again

Nick As Vocky has said in the other thread, bet you have disturbed some if the alternator wiring. Things are tight as std even worse with the Harrop. I will be interested if the change in knock sensor position improves KR as mine produces more KR than expected at high rpm which has meant I have had to reduce ignition advance in the base map to remove it.

Did you check your IAT on full chat? I've seen almost 90*C on heavy use...

[oakmere]

Mine is N/A not SC. I think Nick was seeing high inlet temps not helped by his radiator fans running in reverse!

90 degrees is quite mental, goodness knows how much power you lose with the ignition retardation - do you know Exmanta ?
