HKS EZ Controller Question

I don't see why that would be a problem as long as the connections are tight. This is what I did to my turbo timer.

gl,

I did the exact same thing and it works just like new

Any chance I could get someone to post some pics so I could see where to mount the sending unit, and to see exactly where the hoses are going? I'm trying to read the installation diagrams and an actually picture of this installed would help a ton! Thanks!

you can call up hks to get specific instruct for the supra or you can
try the Blitz install .

gl,

Yikes!

Ooooohh noooooooo... not the pressure tank vs no pressure tank again

stoker6, which route did you take? I did the pressure tank method which was a PITA. I'm also in ttc mode.

Mine is hooked up to the pressure tank too and I was thinking about undoing it but I can't see where the stock hard pipe that connects to the pressure tank is. Can someone explain or send a picture??

if you want to know where the pt is, just look above the starter. you'll see a soda can size...

If you go the pressure tank way, doesn't it not allow for proper prespooling on the second turbo (if your in sequential of course)?

I hooked it up to the PT (HKS recommendation) and don't have any probs. From the info I have taken in, when the turbos are in sequential, the power dip in the #1 to #2 transition is the EBV taking boost from the #1 to pre-spool the #2. The greater the dip the more #2 pre-spool. Some feel the greater the dip the less pre-spool for #2 and it gets "slam started".

So I take it nobody has actual up-close picture of the sending unit installed on thier cars, because that would help me out a ton! I must be retarded cause' im really struggling with this install!

did you get the instructions from hks yet? Just follow it. hopefully the attachment works. Label A goes to the turbo actuators and label B goes to the pressure tank, whereas label C is T'ed off the blow-off valve. Don't forget to T and cap off by the firewall area. Hope this helps.

gl,

tt4playn - Thank you so much for the diagramed picture!!! That was exactly what I was looking for!! What did you mean by the " T and cap off by the firewall" though??

Have you call up HKS and request them to fax you the installation instructions specifictly for the supra yet? You need to read that. It will tell you what you need to T off in that area. It is the hardest thing to do because of the firewall(no room). You have to cap off the T that goes to an actuator down there. The line that goes to that T leads to the pressure tank. That is were you connect the pressure tank line from the HKS unit (note: it is labeled B; B2 and B are same line). You might need to get some connectors from auto zone. People have criticized me for doing this method... so its up to you.

gl,

Since this is being brought up again Does anyone have any 1/4 time with it hooked the HKS way vs. the Blitz way. You get like 17psi on the number 1 with the HKS way. I would think getting out of the hole would be better the HKS way but know one seems to have any numbers.

How are you certain you're boosting 17psi on just the #1...thats senile!

I have no problem hitting 23-24psi at full boost in the cooler weather.

I noticed in tt4plyn's pic that the stepper is point up. That is a MUST!
