Will the system have waste gate control?

 

The tables ARE on the syty so i guess that is not difficult to implement...

 

The egr vavle can be used as one if you program it to.

 

If you're saying use the EGR valve on the back of the intake manifold as a by-pass for boost, no it wont work.

You'd have the severe issue of venting air that had already been metered, and you'd run pig rich when it opened, and that would be more of a BOV and not a wastegate. Not to mention there's no way the EGR valve can flow enough volume to keep a decent turbo (or pairs) from over-flowing the manifold as they continue to spool. Also as the turbos over-spool they will drop out of efficiency range and your IAT's will rise even if the EGR valve could keep the boost at a controlled level.

Use a boost controller for a boost controller to control the wastegate by the vac. lines. That will get your boost under control the right way - dont use something that wasnt meant to do that play such a critical role in such a delicate job.

Also IMHO you dont want the ECU saying how much boost you run, unless it would have it's own kill switch (like a vac solenoid that would close before the boost controller's input and manually force the boost to a lower level (like 6 or 8psi, maybe even 4...) and then use your boost controller to make the adjustments. Your ECU cannot account for changing road conditions effecting traction, and also what you are feeling like doing with your vehicle.

I'm looking to run 12-14psi on pump gas on the street. I wouldnt run that much normally because 1)it's too much power 9 times out of 10 and I'd spin my 315's to oblivion and 2)because I just dont need that much power to murder anyone who wanted to race me.

An in car boost controller would let you adjust the boost to what you want at a moments notice. There are a lot of things I say "leave up to the ECU" but there are are some I dont.

Not to sound like an Apexi freak, but after years of using the S-AFC and the AVC-R, I am more then willing to see what they can do for us. Very good tools for moment's notice adjustment, they have a great interface, and have built in gauge functions. Not to mention they can be found on ebay for a decent price.

It's too early in the morning for a Sunday...

 

I meant the soleniod, which is the very same soleniod used to control the wastegate on the GM 6.5 turbo diesel. In which case you can "in theory" ( case this whole thread is all speculation) program the egr output to control boost levels.

 

its all speculation but it can be done... i have a quote right now for 4k!!!

wow

Those guys in that thread seem to be talking a little over my head

I am real curious what will develop here, I have been researching how to deal with boost for when I finally have enough $$ to buy some.

 

Is this $4K for 1 computer, or is this with the capability to duplicate for a lesser price. How would one edit the tables of this new PCM, and is software available with this price to edit the new tables?

 

its 4k-5k to develop the bin.. after that it can be duplicated..


I would create a definition in tunercat for it.. so it would be a lot easier....
