Who's ditched Unichip or APS boost controllers?

That's correct...the Greddy boost controllers arent much better. Try the HKSEVC or the Blitz SBC-Id. I havent decided which one I will switch to. THe HKS psi version is usually out of stock at HKS, so might end up going with Blitz.
Bruce, the limitation of the unichip is controlling the extra large injectors. It can control the stock APS injectors just fine, and probably even one size larger than those. But at some point, when larger primary injectors are required, the Unichip wont be able to scale them down enough at part throttle and cruise. There are work arounds, but its not ideal, and your part throttle response can suffer, as well as your fuel economy. The stock APS injectors are actually more like a 440cc injector, if APS rated them at the industry standard 42.3psi of fuel pressure, vs. 58psi. So squezzing 550whp out of the stock APS injectors is definately pushing the envelope.
Ok, sorry to get off topic, but I have to chime in on this one....
I've been in a few car clubs, and it's really odd how there seems to be some sort of divide between customers based on the shops they've taken their Z's to.
First off, I try and make an effort to stay cool with all the shops and their owners, as well as all Z owners, cuz hell, at the end of the day, we're all enthusiasts sharing a common (FI'd) interest.
It just really pisses me off when a select few guys are trying to make their businesses work, whether it be Ted at SP, or Rob at Z Car and a few people have to come in and bash another, maybe because of a circumstance, or maybe also to feel a sense of "belonging" to one clan. I just think that's pathetic.
Both shops are very competent and capable, but as some already know and Sharif pointed out, there is a bitter history between these 2 individuals. Nonetheless, both of them keep it on the very professional level, and do not disparage one or the other. It's between those 2 to sort it out, and really is none of our, or their customers' business.
And having alot of friends in the shop business, I have seen a lot of reputable shops make errors or mistakes. That's because guess what, techs and owners are human too.
So don't burn your bridges, guys and gals, and definitely don't listen to the voice of a few. Do your own homework, and see who works out best for you. I've seen one too many shops where marketing does not equal performance, so take that in stride.

See, now theres one of the guys I like, Nismon is a stand-up guy. It does suck the way theres this void, but few people like him and myself oh and Marin that go around that. LIke i said
This is the reason why. People that are car people and level headed.

Miaplaya or Sharif,
I'm thinking all I want from a boost controller is boost control. The old Greddy Profec B has been superceded by newer models that sound more complicated and feature-laden. I've talked to techs who say they've used them to control boost into the 30psi range. I want to keep it simple. Why wouldn't I use the Profec B?
Now, the rising rate FPR that came with my AAM fuel system apparently has a faulty diaphragm, so I get to replace that too. Has anybody used one that has a higher than 1:1 ratio? I may have to leave the car to pay my shop bill.......

Sorry, off topic again.
You are right Bruce, I have bad mouthed in the past somewhat and to tell you the truth I am the only one I know of that has done such here in this scenario, ZCG vs SP, me coming from SP. I can't take it all back now, I suppose. It's a long story that goes back 25 + years that I will not bore you with. Sometimes I have allowed myself to get too passionate about the whole thing and don't think first all the time. I admit that. I'll bite my lip a little harder from now on and keep those things to myself on here.
By the way that was a nice *** ripping you gave to me. Can't say i blame you, all was fair at that point.

The newer greddy boost controllers use a very similar single solenoid approach, so we havent seen any improvments. The HKS and Blitz are the two best out there currently.
For the return fuel system, 1:1 is standard practice for an F/I fuel system. It is nice to be able to control the ratio, but not necessary, provided you have the proper injector size for your power.
Installed a Greddy Profec B that Rob had in stock and it was holding boost just fine. The FPR that came with my AAM fuel system has a bad diaphragm, so they started running out of fuel. New higher ratio one arrives Monday.
Its good to see this didn't end like a bunch of other threads, Id just rather see us Z owners remain more of a family instead of disfunctional homesless naysayers. Both deserve their due credit, we can both see the obvious work they've done.
So, now i have to look into a boost controller option too, ahhhhhh. Bruce2 keep finding solutions man, youre gonna make my life much easier.

Bruce-
I heard from Julian @MRC this morning(daking350Z). They're using his car for some R&D on the UTEC at Turbo XS and he says he's putting down 480whp @10psi on the stock actuators. MY Profec is in and the heavier actuators are reset(and holding) and the problem now is fuel delivery. Julian said at the level stated above he's pushing 94% duty cycle on his injectors and he's maxed out? I guess we'll see what happens when I get my replacement Fuel Pressure Regulator......
