Not yet, but I just got my car running today. And it's got an ISAC. I'll post up when I get some time with it.
 
i would also like to know. so feedback please from the board
 
IF I had a running car I would get the ISAC, but When I get my car running I will be getting the ISAC.
 
I ran the prototype for a while dual EFI pumps, boost control, etc.

Just upgraded to the production style and have to install it soon.

It works. :)
 
I've got one, will be getting it in the car in the next week or so. Someday maybe another one for the STi. On the GN, I'm going to use it for alky and boost control.

I will post back as I get familiar with it.
 
Have one too but the motor is out getting freshened up so it's sitting in the seat for now
 
We put an entire kit on a car Thursday and he came down to the nationals and finished 2nd in one of the index classes. CAR RAN GREAT! I saw the first past down the track and it sounded like it had been tuned to perfection;):biggrin:
 
I haven't gotten anywhere. I broke a rocker stud, so I gotta wait on that. Stay tuned.
 
I just had this installed by the awsome people over at Big Wood Racing and will be making a review post soon. Its on a mustang and not a GN but might still be helpful for those wondering about it.
 
I started tuning on mine tonight and I love it. The boost control is dialed in and is rock solid. You can completely tune the characteristics of the way it ramps in. Never driven a 70 that comes on so quick, so I got it ramping in "slower". My datalogs boost tracers are flat lines now. I am really enjoying tuning pound for pound without burning my fingers, and could tune in fractions of a pound if I wanted to. Alky control is guessed in for now at 7% per psi. When I reach a max boost level I'm comfortable with I'll start messing with this more. But If I have that spike of knock on the 2-3 shift I plan on maybe using the sliders to address this instead of how I've been doing it with FAST which was giving the RPM it shifts down into a spike of fuel in that cell. It would see that spike of fuel when it travels through this RPM in 1st, so we will see.

Other plusses are, a solenoid output I can use for an alky flow control solenoid since I run mine at the bottom of the intercooler pipe. I've had issues with check valves failing and this is a better way for me. Also, the trim knob should be fun and I will use this for boost ramp rate or for boost level. I could turn it all the way up, tune for max boost and turn it down to a more reliable level for the street. That way, If it's ever too close for comfort, I can crank it up but to a level I know I'm tuned for.

This thing is gonna give me a new level of control.
 
So here is what I think about the ISAC after ive had it installed for a couple weeks now.

The Good:

-Control: I am 99% sure there is NO other controller out there capable of what this one is (http://www.isacalky.com/ for list of functions). I mean you can control how the meth/alky is injected from RPM, boost, throttle position, to AFR. Also unlike other controllers its not static. There are sliders in the built in software to adjust using just a simple USB cable to your laptop. No drivers needed to install. Plug and play.

- Install: Install of this kit is no harder than any other standard meth/alky kit. However I want to list this as good because the guys (Eric, Billy, Jay, and Randy) over at Big Wood Racing did an awsome job on the install. It only took about 5 hours (a little under) and is really professional looking. All the wires are hidden and wrapped; Nothing was done sloppily.

- Price: I am a FIRM believer in you get what you pay for in this situation. For the safety and performance you get from this kit is deffinatley worth the 700 something (cant remember exact price) for all the parts you need. And in my case that includes a tach adapter which added to the normal price. For that amount you get BWRs ISAC controller, tank, pump, lines, silenoid, and nozzles.

- Safety: The second best part of this kit is the built in safety features. This really ties into you get what you pay for deal. First off there is the traditional low level sensor that will turn on a light on the ISAC controller itself. But where it gets interesting is is can retard your timing (even boost if you are running turbo or some sort of electronic boost controller) to reduce risk of damage if you happen to run out of meth or for whatever reason it stops pumping.

- Performance: I can also tell you it was worth the money for my setup being as the Eaton powered 99-04 V6 has no way of being intercooled. After installing this kit it raised my HP by 22HP and 12TQ with only an increase of 3* timing and 2LBS boost. Even more impressive is my super flat TQ and HP lines. Most importantly though, I now have room to grow until my internals give out.

So I got sidetracked mounting mine but it's wired into the vehicle.

I was actually thinking that a bracket can be made to mount it to the same tab that mounts the DS underdash cover. At least that's the way I'm going. So it would to in basically the same place as disco stus but a little further forward

Now if I only had an intake system to pressurize
 
Don't know what that adaptor harness is for but to avoid confusion for others that is not part of the ISAC.
 
True. I pull my wastegate, RPM and TPS off of that.

Thats pretty cool. If the price of adding an adapter harness wasnt so much, I'd consider doing that. But even with an adapter harness, there's a good bit of wiring that wouldnt be covered so I dont know how effective it would really be.

The boost controller seems to have all the issues ironed out. Ive never had a problem getting it work for me but some did and the newest firmware update seems to have addressed those issues as Disco Stu's log illustrates.

The controller just keeps getting better and better. I think at this point we're going to put the software into a holding pattern except for bug fixes. It pretty much does everything we wanted it to do.
 
Repeating my similar question from another thread...

Will the ISAC give me the ability to "flip a switch" and go from 15# boost to 25# boost with a mostly stock engine (Razor's alky kit, fuel pump, hotwire kit, injectors, chip, AFPR, etc.) with stock turbo, downpipe, internal wastegate, etc.?
