My LCD screen project, boost, WBO2, Knock, etc

[familyMAN]

How well does this control boost? Easy to dial out spikes while still holding target psi through revs? Has it been tested on larger than stock turbos?

Very interested. I want to ditch my mbc with my car's resurrection and love the idea of having the knock and afr warnings.

Has datalogging been added?

No datalogger yet, I don't know how frequently he works on it, and he is the only one that works on it so it may be a while. I'll email him and ask if he can incorporate it.

The interface for the boost controller is almost identical to the profec b spec 2, and I think it works pretty well. I've got bigger turbos, but i havent maxed them or anything yet, but it definitely does work on them.

Doesn't the Serial out allow you to plug in your logger?

I'm not sure if I missed this thread before or I just meant to come back and check it out later but this thing is very cool.

The serial datalogging port is for interfacing a dataloging cable to it, so the unit can read ECU information. The unit can display the ECU datalog information to the screen, but not export it.

Having had a greddy profec B spec II boost controller, I used the familiar duty cycle approach for controlling boost. Higher the duty cycle, higher the boost. On my car, I had problems with boost falling off 2psi at high RPMS, so added a feature to fix this problem. I called it "Dutycycle offset", and at 4000, 4500, 5000, 5500, etc... RPM intervals you can add additional duty cycle to compensate this common problem, giving you a linear boost all the way across.

Another advance boost control feature is to temporarily reduce boost when your engine is knocking. This is user definable, you control how much duty cycle is reduced when knock is present.

I use this boost controller to regulate boost at 18psi for my 15G class turbos.

Will the greddy solenoid work with this?

[Goallie11]

The reducing boost because of knock feature is really great, something all boost controllers should have.

Can you work on it exporting logs Antero?

The greddy boost solenoid should work because it's very similar to the AEM/mac valve solenoid.

To export datalog information would require additional hardware. I could make a daughtercard that sits in between the microprocessor and the socket to add new capabilities, I'm just flirting with the idea on how to go about it.

Just ordered one cant wait!
