boost controller question

[doggydowg]

Hiya guys

I know you can buy boost controllers where you can vary what boost you are running dependent on which gear you are in can anyone suggest one?

And how i go about doing this on a pulsar ie it has to be wired to the ecu?

I have used a blitz dual boost controller but never one like above many thanks Paul.

Only really needed for a FWD, on a 4WD just keep the same boost for all gears.

Im having problems where it wont run above std boost in 1st yet it runs a bar in all other gears so was thinking i could get around it this way

but you will just mask the problem instead of sorting it out. Have you put the car back to how it was before you started playing around with boost, that way you may be able to figure out whats going on.

Hiya ive got a post going in problem solving area to cover this, if i put it back down to std boost it runs fine evan if i only bleed off 0.1 of a bar so its up to 0.8 the problem is there in first.

It runs fine on rollers in 4th at 12.5 psi, ive replaced fuel filter,fitted walbro,got good grade 8 plugs (which i was going to gap down to .7 today thanks snow) and ive tried it with full tank of fuel so cant be fuel surge.

I just cant see how i can run a bar in all gears bar first yet i cant evan run 0.8 bar in first with out it hesitating/spluttering a bit around 5k.

has anyone here used the gear fucntion on a gtir how would i go about doing it?

Ive tried looking on variouse websites and it doesnt say i dont see how the boost controller knows what gear im in?

Thanks

you set the controller up to learn the gears in the menu, i.e set it first, drive, the set it to 2nd ect..

my old blitz sbc id II had this function with my power meter, but I never used as it isn't needed with our AWD beasts.

I'd try to fix the problem rather than mask it with a boost controller.

Soz mate - not much help like?!?
