Well, in reading through this thread, I must admit, it has been a lot to process. I have the GM 3-Port now, and was going to throw it in the car, and start to tune it. But, I have re-read this thread on quite a few occasions, and am still a little weary about how to tune it.

Can one of the people that have tuned it successfully post a really simple guide on how to tune it? I looked at the tuning of the stock BCS thread as well.. I guess what I am looking to see is a first do this to this map, then do this, them tune this map etc...

So far, I have created a ROM to prepare for doing this, here is what I have (For an 05 0011 ROM):

My boost control load offset is set to 60.
My TBEC is set to all stock values
My BDEL Maps (All of them) are set to stock
My MWDC (All of them) are set to 50.0
My Boost limit map is set to 265 (Raised a little)

Ultimately I am going for 25-26 psi across the board.

What map do I start to screw with first? Then what map next? Should I set the error correction to 0 until I get the boost where I want it? Can someone take a few minutes to just to a 1, 2, 3 list for a dummy like me? After reading all of this thread, so many people are doing it so many different ways..

Thanks for anyones help in this...

 

Search for razorlab's posts. He does it the right simple way.

 

Heck, pm him to. Bryan is very helpful.

 

Update, the AEM solenoid didnt work at all when connected to the ECU with 2 resistors (load was 32 ohm using 2 1W 10ohm resistors). I played with the #60 pill a little and hooked the AEM solenoid back up to the truboost gauge and I'm going to work with it and get the GM 3port.

 

Sorry to bring this back from the dead.... but I have a few questions....

Now that some of you have been using this for awhile. How often do you find yourself making adjustments to boost settings?

I'm still undecided about all this. I currently have the stock setup with the BCS pill removed for 21 psi. I'm considering putting alchy on the car and looking for a solution that will allow for 25 psi.

With all the fuss I'm half temped to simply install an MBC and call it a day.

 

You shouldn't need to make adjustments if you set your boost curve the way you wanted it. The ECU should adjust for you.

From what I understand, if you go the route of MBC then your car will be weak in warm temperatures and overboost and possibly knock in lower temps.

The GM 3-port has been very easy to tune for me. I'd recommend it to anyone. I would've never got it if it wasn't for this thread being created.

 

One more question......

For those running race gas or meth/alchy ..... are you able to run 26psi and hold 22ps without the use of pills?

 

look on page one at post #28

 

Yes but you are on a bigger than stock turbo.

I'm looking for WGDC controllable boost with a range of 22-26psi.

 

Great post guys...A few questions:

(1) For a IX with factory turbo, with the basic breathing mods (TBE, O2 housing, cut airbox), what does a 28 - 30 psi (at peak so ~3500 - 4000 rpm) correspond to in load? And how much can the turbo push at redline (load and boost)?

(2) With the new 3 port GM configuration do you think an aftermarket WGA is really needed? It would seem to me that the mod'd wga would not be necessary as it would only get air when the boost solenoid wanted it to....

Great information...

Ok my Target Load is set for peak at 260 tapering to 220 and my MWGDC is 100 until 3000 and then 50 afterwards yet I am only seeing boost of ~15 psi through the entire rpm range. The error correction was zero'd out from 0 to -20.

From the previous posts I was expecting my boost to be 21+ psi. Thoughts / advice?

 

You might have a hole or tear in the line. Or a boost leak. Usually the GM solenoid takes less WGDC than a upgraded pill and stock solenoid.

 

I need WGDC in the 70s to get 20 psi. Do you think I have a leak somewhere? One day I got a spike to 22 psi but then the next day I got a constant 20 psi. Maybe I'll check out my connections this weekend,

 

So I leak tested the system and there were no leaks to be found (held 25 psi easy)...

When I load the car (6th gear pull from ~2K) I get the car to spike to ~20 psi and then immediately drop to 15psi. Do you think my WGA could be opening too soon, thus causing the boost to drop too much? To me it feels like the car wants to keep the boost at 15 psi (even though my target load is 260 ~21/22 psi)...

The car did the same thing the day before with the MBC...I thought a friend had played a trick on me by dialing down the MBC (but that was not the case) and I fixed by just turning up the boost.

I have access to another brand new 9 WGA, should I just replace? Thanks
