Thread: Once you go BAS .... You can never go back!

I can only agree with you about V2 of the 170hp tune!
Its like he's fixed the whole vehicle all over again. I can almost drive 'normally' in 1st and 2nd! The jerking from the sloppy driveline has nearly been overcome.

I don't really need or choose to use all the power/torque from the tune but it also makes a huge difference to drivability through light and medium throttle.

Its also good for a laugh when a rice cooker pulls out to overtake on a hill and they start blowing smoke like a, well, rice cooker and nothing happens.

I'd be curious to know how the TDCi with this tune stacks up against a V8 LC while towing. Pat

Numbers are not the final word on "real world" experience behind the wheel. But as a start point:

Toyota info from Toyota AU web page for the 70 Series
4.5 litre V8 Turbo-diesel engine
151kW (ed: ~202hp) power
Powerful 430Nm of torque

TDCi w/- BAS 170 Autobiography
2.2 litre inline 4cyl turbo-diesel
(~127kW) 170hp
450Nm torque


T'would seem the V8 has a lot of scope for for a tuner to make it breathe fire!

I think it would still feel a lot easier with the V8. Even though the d4d is no engineering masterpiece, the cubes are always going to make lighter work of it.
The 2.2 punches a couple of classes above its weight though.

In standard form the TDCi always has the right gear,with near V8 performance it would really show it's hand,the D4D on the other hand has a gearbox that is happy to sit on 80 in fourth or over rev in 5th. Pat

So after swapping the stock ECU back into the vehicle on Wed last week, took it to Land Rover Malaysia early Thursday morning.

Sadly they had some issues and couldn't get the new 10AS to talk to the rest of the car's systems. So they backed out, put the original 10AS back in and asked me to come collect the vehicle. Maybe a week or more before they might want to try again.

So the last few days been driving with the stock ECU in place thinking I can bear with it for a week or two.

Yeah yeah - Nah. Wasn't working for me. After I put the kettle on for breakfast coffee this morning I grabbed the two 'ners and a screw driver and had the other ECU (with BAS 170 Autobiography V2 tune) reinstalled before the kettle boiled!

Ahhhh..... Feeling much better now.

One thing I've noticed with the new 170 map is that it doesn't seem to have the fire breathing switch at about 75% throttle any more. It seems to have been spread out more.

The 150 map still does it though!
