new toy

figured i'd give the electronic side of the boost controller world a whirl, and what better way to do that than to grab an older model that was never meant for this country in the first place?

hope i can find instructions in english :thumb:

Nice looking setup!
I'm curious what the maximum boost is that a setup like that will work with.

[cordes]

At least it has english on it. That will be a big help if you try to figure it out on your own with no instructions.

Reminds me of my Blitz DBSC, the only english instructions are 4 pages long (and thats somebody who wrote them based on trial & error) but the Japanese manufacturer version is 28 pages, wonder what I'm missing!

Wow, looks like somthing out of star wars.

How exactly do these electronic boost controllers work?

do they control a vacuum feed to the wastegate with a solenoid?

Why does this Apexi unit have something on it about injectors??

correct, it uses a solonoid mounted down by the wastegate can. as for the injectors, im still somewhat fuzzy on features but it seems this thing can monitor pulsewidth. it may also feature some piggyback fuel adjustability

HOLY COW THOSE THINGS ARE EXPENSIVE!!!!!!!!! $100 is about the minimum you can buy one for!!!!!!!! :yuck:

then a new one goes up to 400+!

All your boost are belong to us...:lol:

yep over priced and they can't control the boost fast enough so you get a boost spike of 1-2psi or more depending on the unit. SCC tested a bunch of them a couple years ago because they claim they make more power than something else. They do, but only because they allowed the boost to spike for so long before being able to control it. Nothing beats a grainger valve when it comes to limiting spiking :) Hope ya didn't pay through the nose Kajja

price wasnt too awful bad. i plan on spending plenty of time playing with her in low boost levels before i go crazy, i get some wild creeping with my grainger too. i guess t-3s and 3in exhaust dont play well

Good boost controller:thumb: IMO. I installed 1 years ago on my friends '96 Talon, worked great. I had A set for 1.2bar or 17.6psi & B set to 1.5bar or 22psi :eyebrows:
For injector duty cycle you tap into the injector wires from the ECU.

It may show the new version, but I'm sure the installation & wiring is the same.

creep isn't a grainger's fault. Spike is. Creep is from the wastegate or housing not flowing enough. If you port out the wastegate hole it won't creep. 89 T2's seem to be the worst at this since their holes is smaller than the earlier T2's.
Spike is caused from the wastegate not opening quick enough. Electronic BC's have this problem. Chrysler would of had the same problem with a Mitsu turbo if they had plumbed it like the T2's were plumbed. But they realized it and gave the mitsu full boost signal till it got to 7psi (wastegate spring stiffness) then bled boost off to raise the boost level.

yeah i didnt word that right, didnt know about the 2.5 swing having a smaller hole though. guess it would be worth my time to buy a TU 3 incher then eh? is it possible to drop the swing in car?

crazyoneeye: did you guys install the older model like mine? or the newer one? thanks for the link, i figured the newer s avc-r's instructions would be my best bet

Thanks guys

[GLHNSLHT2]

the SV doesn't have the hole, it hold the flapper. The Hole is in the housing and 89's got a smaller hole. If the turbo has been apart and you used anti-sieze then it might be possible in the car. If not I find lots of liquid wrench and a blow torch works well. :)

Yes, it was the older one like yours.
