I installed a beta prototype of the ISAC controller on the WE4. :smile:
Installation is straightforward, I suggest making a simple wiring diagram in advance in how you want each wire to be used (or not) for your particular car, due to the wide variety of controls and options, having a good plan in advance makes it much easier.
The harness is plenty long and plugs into the ISAC with three connectors and this unit has a built in MAP which was ideal for me since it was replacing one of mine that also had a boost line to it already under the dash.
It features a 5V output as well if you need it run an external sensor, which the unit can be programmed to use if desired.
I programmed it with the desktop and there's LOTS you can do with the unit, it will fit cars that wish to make their DIY kits progressive with just about any type of pump, and also features a boost controller with PLENTY of tuning ability and options for the street and the track, and I'm sure it can replace simpler alky. controllers easily as an upgrade.
The unit features 2 pump outputs and since I have two EFI type pumps in that car this one unit controls them both easily. PWM ground output.
I have my boost controller set up as a simple PWM replacement into dual solenoids stock wastegate system with HD actuator, and it replaces the BSTC unit just fine.
USB port in the front for adjusting and connectivity as well as Data Logging with a suitable laptop in the car if desired, I haven't done that yet since my laptop is a very old windows 98 machine I have only used for directscan.
Other features I used were the low alky. input which automatically scales the boost back when triggered, same with any overboost situation that the MAP sees it will also trigger that protection scheme, set it to a low number but the arm and HD actuator limits that to about 17psi. or so mechanically.
The unit also has a second solenoid type output that can be set as a window switch with other parameters such as TPS, RPM, and of course pressure.
Since my solenoid 1 is PWM for the stock solenoids I have #2 open right now, and may program it for a simple target boost bright LED or similar feature, most highly modified cars can use it for their complex wastegate control systems.
I may also use it to replace a solenoid switch I have installed years ago, that adds a second nozzle to one of the pumps at 24psi. boost. This output would easily do that via simple programming and hookup.
The unit has 4 inputs as well you can hook up if desired.
As mentioned I use the low alky. and have the gear switch input hooked up as well it was right there on the BSTC wiring so I simply hooked it up.
Other inputs can be set up for a pressure switch which can activate a safety mode if no alky. pressure is detected or it can be used for a gear reset switch if you are configuring the unit for various boost control functions per gear. I'm not it's the daily driver, great feature for racecars.
Another input is for an external pressure transducer or MAP to be used and logged with various programming parameters due to 2 bar, 3, pressure only etc.
There is also a nice feature I do use which is a trim knob on the front of the unit which can be set to OFF, control boost, or control boost rate, or control alky. flow, or control A/F over a +- 25% range.
That brings me to next week or the weeks after testing which is wideband A/F control which this unit can do with alky. flow control. Another great feature and it's set up for various wideband units, I have the DIY wideband I built hooked into it.
Obviously there is also a pump test button on the front which you can set the % of alky. flow for, in a programmable box in the software.
I use 60% to fill the hoses and bog the car but not drown it with the EFI pumps.
I suggest everyone who needs or wants an alky. controller, boost controller, failsafe control, solenoid control, etc. to take a look at the software which is posted in the link above and can be run on your computer easily with no hardware needed to check out the various features.
And of course it was designed by Turbo Bob so you know it's a good product.
I replaced 3 boxes with 1 small one.
It is going to be a great product for our cars. :smile:
