This is the whole point of the Syvecs, Where as most have gauges all over the dash for lambda, Oil Pressure, Oil Temp, Fuel Pressure, EGT etc..... Which costs over £400 and in the event of a problem its going to be missed if you are driving hard a 600hp car..... and it certainly wont be logged.
The Syvecs range take all these these inputs direct into the ecu but what makes it different to most ecu's is it actually does something about it.
For example:
It monitors fuel pressure relative to Manifold pressure. If a fuel pump fails or wiring is overworked (like it is on most supra fuel system) then it will spot a problem and automatically compensate.... If it gets so bad it will put in a limp mode.
Oil pressure is monitored based on RPM, if the there is oil pressure problem at high rpm or on track... Limp mode or Cut engine if severe.
Egt's get to hot then it compensates in Fueling.
Proper Knock control which allows me to produce some of the biggest HP figures on pump fuel in the world for the 2JZ.
Closed loop lambda control with different variables of Trims amounts based of Manifold pressure and proper failure detection.
Oil and Water temp trips if gets too hot.
Warm up Limps (which jamie hate ) Stops car going full power until oil is warm enough etc
Monitoring of Crank case pressure and trips if gets too high to save a block or seals.
But Most of all is the the Logging. The ability to log items at over a 1000 times a second with out having to have a laptop plugged in is price less for diagnosising problem and for properly mapping a car.
This is the main reason why Syvecs, Life Racing, Pectel and motec are not cheap.
But trying to configure say knock control at only a maximum of 30hz on like the LINK ecu's, Megasquirts, emeralds etc is a waste of time and why no one uses it.
Why Waste all the money on building a powerplant and fitting a cheap management. Its like building a house and not putting a roof on it!
Go back 6 years and see how many 2JZ's used to let go at only 500-600hp and now try and find one these days where the Syvecs is around.
