howdy, i recently installed a turbosmart eboost, but i cant seem to boost over 7psi, the guage runs three adjustable set points, which i have set at 1-7psi 2-10psi 3-13psi, i run the eboost soildnoid straight of the trubos wastegate, so there shouldnt been any factory boost cut out stoping it should there, any suggestions.

Make sure you have the solenoid hooked up correctly. Port 3 of the solenoid is manifold pressure, port 2 is actuator reference and port3 is vent. There are three setting boost setting - SP1, gate pressure and sensitivity. Set SP1 to you desired boost level then adjust the gate pressure until it just starts to overshoot your desired boost level and set the sensitivity so that boost dosn't drop off higer in the rev range.

That said I have had alot of trouble setting these boost controllers and dont really have much respect for them.

cheers, il have another go at it, yer its a bit bloody tecnical for first timers like me self, gate pressure, sensitivity, heaps of stuff to mess with, but il keep at it, even when i reset it all and set sp1 at 10psi, still couldnt get over 7psi, checked the hook p three times now all looks right but will check once more just in case.

The values you put in are a little miss leading as they are not in boost pressure. It may be Duty Cycle but I'm not really sure. So if you set SP1 to 10 it wont necessaryily give you 10psi. Try setting it 20 then 30 etc etc until you get the desired boost level and then you will proably find that you will have to increase the sensitivity to stop it bleeding off in the top end.

Does anybody know if there is any kind of feedback control as in closed loop operation PI or PID loops, or is dumb as shit? Has anybody check the duty cycle on the solenoid to determine if it changes up and down or only up or does it change at all from the set DC.

ok just went for a spin out on the old knob high way messing around with set point one i tryed seting it at 20 with a gate pressure of 20, and then 30 with a gate pressure 30, done a few 1st and 2nd gear rolling take offs, evry time i booted it, it would still only get up to around 7.2 was the highest, but every time i changed gears, and flanted it again i would get a sudden boost spike to around 9 some times 10 but would drop straight away to 7 or lower. had the sensitvity high as well.

dam thing would all ways crunch a little into 4th and 5th and back into 4th, at revs its ok around town driving or cruzzen.

Check the over boost isn't set at like 8psi.

    • I was just driving into work and while on my drive, I went to accelerate and noticed the car would sputter/hesitate and I’d hear a few pops from the exhaust before it started going faster. Then I also noticed that when I push my clutch in, the car would die. This all started happening today. Any ideas?
    • That is a lovely Volvo, just saying. Yes I should have got an 260RS when they were cheap. I do regret now.
    • ^ lots of good points made above. The thing is, "aggressive" or "flush" fitment is relative depending on how much you have been influenced by social media. My starting point is always "look at the Nismo RWD specs". That is where you should start, then start measuring as GTSBoy as sort of mentioned, because every car will be slightly different. My 8.5"+35/9.5+38 will not be "flush" enough for you because you want more "pumped" look, which is why you measure. Tyre sizes and brand/models also make a difference. Some tyres are more chunky/square, some are more rounded. That means you could get away with more aggressive offsets without rubbing. But then it also depends on your ride height. Also depends on how much your car copped damage before being shipped from Japan. So it goes back to measuring your car yourself and determining what can work. Those Nismo specs are used bacause it's a safe spec for standard car (suspension. body) with chunky tyres. But then I put 265/35 wide tyres on R34 GT-R wheels, and currently run 285/30 tyres on 18x10 wheels.
    • Sounds pretty awesome. I recommend creating a new build thread and posting all your goodness in there.
