Actuator controls, Why?

[Bobbit]

I know that our blessed 3rd gen rex\'s are nearly old enough to drive themselves and that when they were built things were not quite dependant on electronic and computer as they are now so we can forgive the designers for what they can up with, but why has no one produced a better control system for the turbos? To my limited thinking, it would be better to do away with the whole rats nest etc and have a computer controlled actuator or some thing similar, has this been attempted in the past and failed of would it not be possible? :3Confused

Im sure with enough money chuked at it and a good Motec system it could be done, but no one ever has those budgets

could a simple control that changes the actuator when you hit 4000 rpm work? Or am i missing something that mazda spotted and decided that the best thing to design would be the rats nest?
What control mechanisms do other twin turbo cars use and are any of them as complicated as ours? Or indeed would any of them work with the rotary engine?

It would work: but you\'d have a massive dip in power due to the fact that the second turbo is pre spun for reduced lag and power drop. That\'s the main problem issue.

Well it s a lot more than 1 actuator, there are several. And 4k rpm is not the only requirement for bringing the 2nd turbo on line.

As Gary said, anything can be made to work with money. But if you had that much money, just send it to Rotecknics and get the standard setup working properly.

Im sure any of these things can be got pver electrically, dont forget 15 yrs ago, ecu\'s and electronics were not as they are today.
The biggest cost would be R&D.
Once R&D sorted, it would probably be reasonably economical, but doubt it would any better shelf life on the products as it has now.
Most of the rats nest are now being replaced after 15 years, would an electronic system last longer, I doubt. So cant see an advantage in the R&D. But would be very interested to know, none the less
