Do MINES ECUs have a safety map?

 

Reason I'm asking is that my car only seems to be devloping 5psi boost of late.

 

If they do, I figured I'd try the 1M resistor trick to see if that sorts it before I start looking for a boost leak.

 

So can anyone point me to a 'how to' to do the Det sensor short please?

 

TIA

Well, I was always under the impression that air was sucked into N/A engines at less that atmospheric pressure hence how you get vacuum assisted brakes.

 

the vacuum is created when the throttle is closed, diesels have a vacuum pump fitted as the intake system on a diesel doesnt create a vacuum as the throttle is connected to the fuel pump.

So the feed for the servo assist would come off before the super/turbocharger then rather than be plumbed into the plenum like a N/A.

 

The old 24v Senators used a reservoir with a valve in place to actuate the dual ram induction system as it operated when the throttle was wide open at 4k rpm so there wasn't a significantly lower pressure to scavenge from. I was just wondering if similar systems were utilised elsewhere was all.

supercharger or turbo is just forcing air into the plenum, so everything just stays on the plenum, if you look at the vg30de vs vg30dett you'll see the brake feed is on the same art of the plenum :)

Ah! Right, I get it now!

 

Even a turbocharged car sucks when it's off boost.

 

DOH! I knew that, I just had difficulty putting two and two together.

 

I'll stop asking stupid questions now.

 

Thanks! ;)

 

ETA, my mate's just dropped of a handful of 1Mo resistors so I'll give that a try at the weekend.

It's alright mate, sometimes things just have to be explained before it all clicks together glad i could make it click :clown:
