Engine running at last but issues....

Yeah it should be about 10-11 psi iirc or more (i'm not sure but dest was saying something about 15-16psi)

Would only expect that with a set of uprated chips fitted. 3B does not have overboost facility....unfortunately.

Mine with a chip gets between 21-25 depending what mood its in.

I'm sure its above 11, there is threads on here saying what to expect from a 3b.

Pressure in a 3B is 0,85 bar x 14.5 = 12.33 psi I think

Just found an article from 1991 that states that during the re-development of the RR (Ur q) into the 3B that boost was reduced to a max of 0.75bar with tweaks made to the ECU to ensure 220bhp so laong as 98 octane fuel was used.
On the way home last night max in second was just shy of 0.6bar, but in 6th 0.7bar was achieved, so pretty much right or should I get 0.7bar in all gears?

If your boost is at 0,4 bar your in the ecu's safe mode.
It should keep 0.8 bar from around 2000 rpm up to... i don't know but for quite long

sorted

Went to Tim Coopers last who read the codes and found I had an open circuit on the intake air temp sender that sits on the top of the inlet manifold. Resoldered back on...very carefully and no more error codes. Picks up like it should now and hope there are no more gremlins for a while .

Brilliant, thanks for the feedback, one to look out for in the future.

Cheers,

Steve.

P.S. There is a Fault code reader available in the group buy area if you need one....

[Acidburn]

Glad you got it sorted, what sort of readings you getting now for performance?

performance

Took 2 values using the speedo and stopwatch yesterday and car will do 3.1secs 30-50 in 3rd and 4.2secs from 50 -70 in 4th. Once RR session done will be fitting these 265bhp chips I have been given, Keen to see what difference it makes to these figures.
