Hi,

I have some doubts about what is actually better to go - standard my99/00 ecu with 3port boost solenoid or aftermarket electronic boost control with its solenoid...

What are pros and cons for both?

How good is boost control in standard my99/00 Unisia Jecs ecu - which seems to be not as sophisticated as new age Denso ecus... ? What about overboost risk which we can reduce with most (all?) ebc's?

And what if we give all boost control to ebc? I understand ecu has completely no control over the boost then, so what in case of need of boost reduction?
Is the only solution a reasonable driver knowing when to select which boost then?

Anyway I believe ebc might be better to keep boost on higher revs? Anyway as long as turbo physically can do that?

Anyway in general - what are advantages and disadvantages of both ways, please? I think it's the question mainly for mappers... they know this stuff the best...

cheers

 

nobody has any thoughts on ebc vs ecu for boost control?

 

I'd say an AVC-R is better than the ECU as it allows you to do gear based boosting. the inbuilt boost control is good but it won't hit you boost targets in lower gears AFAIK

 

cheers - that would be kind of advantage, indeed.
