Hmm that's new information. I'll have to look into that.

** plunger/valving requirements for more than nominal lift increases.

They could also be breaking the locking pins with over design load spring pressures.

That would be correct. DOD lifters require a different lift and ramp profile to take up tolerances in the de-activation pin. I'm guessing most performance cam companies either aren't aware of the...

Well. I need a custom cam blank since so far I haven't found anyone that makes a cam for the LZ9LZG engine.

Internal parts then externals...

Well this is quite constructive. Why do you think I'm starting my own software business?

That of course is far from the truth.


What I AM trying to do is get DOD/AFM working with a VGT....

To an extent I'm sure I could... But for now I'm content using an 'off the shelf' 2-3 bar OS and worrying about the mechanicals and VGT.

The mechanicals are where I'm spending my time right now....

So for now I'll have to disable boost in DOD mode. Ok that'll get me rolling....

Joe,

Yes and no. I've decided EFI Live is my best option. But if I can plan before I buy that frees up $800 bucks for a custom cam. Obviously I'll need to buy prior to starting the first time....

LS327,

Why do DOD lifters go boom??

Swingtan. Yes I'm in the US. Do you have any for sale? Obviously I could buy brand new, but I figure someone has some they've replaced with regular/performance lifters that they will otherwise be...

That certainly doesn't reflect in his comments. I've got two engines that need tuning. One of which is still under construction. Thus far I've decided to purchase an EFI live tuner. However my build...

Again asking questions to make an informed purchase of a tuner....


Is there anyone that knows whether custom control logic for six I/O is possible without an entire OS rewrite?

I'd like to...

Taz, your attitude speaks to the reason I'm not a current customer.

I figured it makes sense to be sure the software options and custom OS's available will work with the build I am planning prior...

Is there a way to adjust control logic in addition go mapping on custom/additional I/O's?

Does anyone know how many spare I/Os an E38 from a 2008 Impala with 3.9L?

Does anyone know if I can modify an E38 to allow boost while still maintaining the displacement on demand or active fuel management functions?

What I'm trying to do is run a turbo, while still...

I'm not familiar with the V2... however why not use a stock GM one? Is there any specific reason you want a K type?

Typically K type thermal couples need an op-amp to amplify their signal to the...

Does anyone have any displacement on demand lifters that they would be willing to sell?

It sounds like the Fleece unit is similar to alternative option. However for nearly $1000 maybe I can get an industrial micro controller up and running and programed for less.

What kind of scope...

The AVRs are a decent chip to mess with. I'm pretty sure there are other PPC chips available perhaps a ARM series, though my experience setting up the Dev tool chain with Cortex A8s has been less...

GMPX,

Another dumb question....

If they are using COTS processors, flash and controllers that pretty much leaves A/D, D/A, amplifiers and communication buffers to be put into their custom...

GMPX,

You certainly are right. Asking has a higher probability of returning results than not asking.

Now that I know what others have uncovered and not uncovered I can focus my efforts where...

Joecar,

The vehicle is the project (engine specifically) but the ECM is part of the deal. Since GZm has never sold a gas engine with VGT it's not part of the ECM to my knowledge. That makes the...

Enthusiasts helping enthusiasts. It sure sounds like it. I'm not sure why I don't qualify as 'a direct application of the EFI Live software'. Also I certainly saw nothing so far in the forum that...

GMPX,

What you've described in your previous post sounds essentially like BGA ICs.

What I am trying to get a feel for is the type of I/Os available. Of course I figured the first place to start...
