Yes the engine is still protected because other components and sensors on the engine will provide faults if boost reaches more than my box allows.

Thanks for this Pete,
Sorry, just trying to get my head around it a bit. With the box, is it in essence something then that disables what the interupted wire does in limiting the boost in a way that sends no fault codes, or does it generate a new false signal back into the system where the max setting coming into it which the user determines is matched to an output max signal which the ECU triggers at?
If the engine overboosts for some reason, how does the engine actually know this is happening and how does it respond differently to a standard setup.
I find this question a hard one to answer because if i gave away the full understanding of the box and the TD5's elecronics then i would have to compete with other box makers as they could learn from my knowlage on the system.
There aremore than one failsafe stratgies running on the td5 engine, if one of those systems compleely fails or fails to report a another system picks up its own fault and reports it,and acts accordingly.
If massive overboost is made then the boxand others ystems respond.

B-A-S any idea of price yet?..thanks gaz.
I'm trying to ascertain if it removes a failsafe or alters a failsafe, thats all. I mean LR have gone to the effort of putting that failsafe in there, what I would like to know, is with the box will that particular failsafe still work at a revised boost pressure which is just above the new higher boost pressure used but otherwise as per normal, but it sounds like it will not work at all and relies on other backup systems instead to do the job. Having a full understanding of what I'm doing to the motor is part of my decision making process of whether to throw the dice with it or not. "Yeah Slunnie don't worry it's all good mate" isn't good enough for me because I've read that statement before WRT an alloy steel manufacturing process which was infact not correct. I've also been on the back of roughly $10k in transmission work because the "Auto will be fine" and so on. "Yep, she'll be sweet" wont buy me a new motor sometime down the track if it's not - just like "the auto will be fine" didn't pay for that either. I don't mean to be a thorn, but good faith is history for me.
I fully apreciate your concerns and totaly understand your questions.
The fail safe is lifted ultimatly from the standard pressure and would cut back in around 23psi IF other systems dont do it automaticly first.
What i will never says is "It will be fine" the cosice to modify your car will always remain your responcibility and i always state any tuning done to a car could have problems, if a customer has any worries what so ever i dont recomend you do it.
Ultimatly what i make and sell is tested to the best of my abilitys but if im not fitting the product and setting it up i cant be held responsible for misuse or incorrect fitting.
When i produce a product i do my best to cover all angles regarding relilability of the product and the car its fitted to but in the unforeseen circumstance problems may happen as will all modifications.

Q for Pete.
Is the box going to make a noticeable difference on an already Remapped (your map) car with auto. Doesn't the auto tran have a torque sensor that will communicate with the engine ECU if the output is too high? How high is that point?
I keen on the idea but I’m concerned weather its going to give me much advantage – suppose it depends on price too.
Im honesty my stage2 map is all you need on a auto , and i recomend you leave it as is.
As you say there are limiters for the auto and pushing it will only be asking for trouble.
Regards Pete
Is it any benefit in an unmapped TD5???
IE any performance increase??
Thanks
Andrew
It will increase performance slightly but i dont normaly fit on a standard car because mixture/fueling is set already to an optiminum at the factory
We persoanly only fit when we have added boost mechanicly to a stronger chipped car to help with its performance and or correct an over fueled or smokey car.
