Boost Question

[butthead]

Hey Guys

I was having problems with my Blitz boost controller, every setting that i tried I was getting 20 or 21 psi. So now i have turned the controller off & i'm still getting readings of 1.1 & 1.2 bar. My HKS boost gauge seems to be working properly.

1.1-1.2 sounds right... well, if not right then how about holden's term for oil use, "within acceptable limits"...

your gauge is showing 20-21psi or the boost controller? all the settings could produce the same levels if the gain etc was set the same?!?!? maybe the thing's reset itself???

bit more detail would help...

[butthead]

both my gauge & boost controller are showing 1.49. I've got 3 settings 0.7, 1.0 & 1.4, but my gauge reads 1.4 for all settings. The acceleration feels the same.

Could anyone explain to me how to set it to 1.0 bar?

Has anyone got a blitz boost controller SPEC R dual solenoid.

hey butthead,

i'm running a spec r in my gtr as well. just went to check the settings:

i'm running 0.92-0.95 bar (depending on time of day) setting is 45 and gain is 10. spools up quick with minimal spike. to get 1.0 bar, try increasing the setting and leave the gain value alone.

hope this helps!

thanx poop

I"ll give it a go,

Do you think the settings will be same, the turbo's not standard.

hey butthead,

i dont think it will be the same 'cos i'm running std turbos.

the gain sets how quickly it come onto boost but if you set it too high, it will spike. from what the manual says, we should have this set at 5 and increase it with caution to the point where the spike is nominal but yet, gives quick boost response.

if i were you, i'd set the gain to 5, and slowly start adjusting the other variable. i left my gain at 5 and started the ratio at 20 and increased it by 5 everytime just to see how much it increased boost by and was able to find a ratio of 45 which is approx 0.9 bar for my car.

i guess, trial and error would be your best bet.

what do you mean by spike (overboost) ?

YAP over boost
