All in 1 electric turbo timer/boost/nos system controller??
 
Was looking to buy a boost controller and turbo timer and ran into this. Has anyone heard or has any experience with this product? looks pretty reasonable and check it up on google. It looks pretty decent.

I'd avoid it. It's cheap electronics and I wouldn't trust my engine to it.

Your FD deserves quality products, not the cheapest Ebay junk. Get a good used Profec B if you want a boost controller. No reason for a turbo timer, the FD doesn't need one. And NOS controller? Don't waste your time with that.

That unit is a joke...

You own the Japanese super-car.... Your modifications, build plan, parts, and craftsmanship should reflect as such. ;)

Turbo timers simply aren't needed. They do serve one purpose though, making it easy to hot-wire your already spliced ignition harness.

For a EBC I would run a Profec or Apexi. Most people like the Greddy ProfecB and it gets great reviews for longevity, adjust-ability, and quality. I use a MBC on my single setup. It is a simple but quality piece with a good price.

Before I went single, I used two of these to control my twins in the sequential manor. They worked flawlessly. A link on this is here:

looks like it was inspired by Greddy designs and could be almost a direct knock-off. It may actually be a decent box and I wouldn't hesitate to try that on a turbo Civic or less expensive project. I see limited risk here; it might be a piece of junk or it might be functionally the same thing as a much more expensive product. If you are worried about some kind of crazy boost spike just set up overboost protection in your engine management system (stock ECU already has fuel cut and Power FC can be configured as well).

My opinion of the big brand-name electronics has declined over the years--it's not like a Greddy or Apex'i is that advanced or well made anyway. They're just expensive because of currency exchange rates and because of paying for the brand name. You've got to understand that there's really nothing to an aftermarket boost controller; they're pretty much all the same, with only minor variations. A nitrous controller is a window switch or rpm-activated switch; it could be used for methanol injection or some other device. They're pretty simple logic circuits.

The solenoid in the picture looks a lot like the AEM/Haltech/Grimmspeed solenoid (made by MAC). That's a quality part.

I have $5 that says that's a knock-off too.

sometimes i wonder if the big brands actually do commission items from taiwan and china because in some cases the knockoffs are almost indestinguishable aside from the lack of name brand logo. generally i would think that this is a huge hit to morals from the honorable japanese but i just don't know anymore.

i have had issues with both knockoffs and name brand items so i don't know either.

people use manual boost controllers, which is a little stupid valve, so that probably wouldnt hurt - unless it failed. If your car has enough mods to be in danger of spiking or boost creep I would strongly recommend you get a nice boost controller that comes with a nice solenoid like a profecBII.
anyone who has worked with the stock rx7 long knows that solenoid reliability is worth the investment.

A 3 port boost control solenoid fails in a safe position. If the solenoid fails to open, pressure continues to flow to the internal wastegate actuator, dropping boost to the spring pressure. It also fails in a safe position if you have an external wastegate. I suppose it is possible for the solenoid to stick in such a way that boost would spike uncontrollably but I have never seen any EBC solenoid fail like that.
