Thread: TC plus centre diff lock - when?

Does sound like a good thing. Isn't it required with the 170 BAS remap, but not with the 150, or have I got that wrong?

COOL i just love blind statements like that.

gabs his calculator. fudge factor for soak.

yeppa you will get close, 2 deg above ambient if you are travelling at about 537klms.

The I/C is strongly recommended for the 170 tune, and is probably needed to get max power. But is a good thing for any state of tune

Buzzzzzt. Your calculator or theory needs tweaking

With 30C ambient, Measured temps, not blind statement:
- in the range 35-55C after stock IC (on stock tune, driving style ranging from gentle to "like i stole it")

- in the range 45-95C after the stock intercooler (on BAS170 Autobiography tune, driving style between gentle and "sub-minute bursts at full noise").

It was amazing how quick the air temp climbed with just short full throttle bursts with stock IC and BAS tune fitted).

(Yes I ran the 170hp tune with stock IC, for brief runs, before the new larger IC shipped).

Consistently 32-35C with the larger allisport IC as sold by BAS with the 170hp tune and any style of driving from gentle to madness.

(If I sit on 160km/h for an extended period on a highway run the post-IC air temp gets up to 40-45C but I consider that kind of driving an exception case. It also drops temp very fast when you back off the loud pedal. )

Neil,
Do you see a need for a EGR gauge, or does the I/C keep it under control. I seemed recall that the BAS detuned if EGR gets too high.
Apologies if This Q confirms my mechanical ineptitude

so still above ambient then. look the hotter things are the easier it is to cool down initially. its much harder to say get the last 10 deg down. same reasons why a cup of tea with no milk will cool down faster than a cup of tea with milk

i think you mean EGT sensor

in the 2.4 the EGT sensor is in the EGR valve body. this is unlike tuners who tend to stick in in the manifold itself.

as a result with most or many tuning chips that firstly shut down the egr valve also disable the egt sensor.
the became apparent in the early-days of the 2.4 when we were making up blanking plates just like we did with the TD5, as a result we got a tonne of error messages. as result i suspect that as i said before the aftermaket chips flashes etc shut down not only the egr but the egt as well.

but as i said that was early days of the 2.4, it may have changed with the 2.2

Im regularly seeing the exact same temp on both sensors.
