E38/E67 ECM Speed Density Virtual VE table

[Redline Motorsports]

Here is the calc pid I am using;

*CLC-00-032
factor 0.0 2.0 .1 "{CALC.AFR_AUT1.AFR}/{E38.AFRATIO_DMA}"

Obviously use the WB you are using. Then create a map that has all the required load cells and start logging.....

Thanks Mick & Redline - i got it to work.

Any updates?

Why are you worried?

RTT is the shiznit. I dont need no stinkin RR!!!

How's it going??

Wow this is awesome that you guys have come up with this virtual VE tables. Right now I am using the other tuning software (you know ) for my E67 ECM in my Ion with the 2.4 LE5 with VVT, now if you can figure out the cam phasing part I am sold and going to get EFI live. This will make tuning for boost a lot easier for people. Right now others are disabling the Dynamic Airflow and tuning solely off of the MAF, its working but it is not the right way to do it.

With regards to implementing the Cam Phasing part of the equation, it is a little tricky for many reasons as you could imagine.
During development we had the cam phase calculations factored in but on some applications (the Northstar in particular) the numbers produced VERY odd looking VE tables.
As an example on the Northstar the exhaust cam at 1400RPM could be anywhere between 24deg or 10deg depending on the airflow figures.
That is a bit hard to factor in to a calculation that expects one fixed figure, eg 24 deg or 10deg.
Just when you think there is an easy answer a 'what if' bites you!.
Only experimentation could prove this, but I think if the cam phase values were not touched everything would still be fine in final calculation.

Yeah I can only imagine the wrench that throws into things, all of the new technology is great but it makes it harder for tuning companies to crack it. I will keep an eye out on this topic and see what comes of it.

Thanks

I used the Virtual VE table yesterday to tune a VE GTS A6 with a 222 224 112 cam. It worked a treat. I had the pids setup for a BEN E38 and a MAP that displayed the BENs with the same axes as usual and it modded the Virtual VE table just like a regular Custom OS LS1 autotune. Its great stuff.

Why are you worried?

Because I'm an EFIlive user too.

You are the one on LS1Tech bashing the RoadRunner...

Man, if you think thats a bash you're a bit touchy.
Just a FYI, I have a Moates APU. I respect the man greatly for his accomplishments.
I wasnt bashing anything, that was more a joke, snide comment, whatever you want to call it, but it wasnt a bash.
PS you cannot find one other comment from me, positive or otherwise concerning the roadrunner.

Not really touchy, but it just seemed a little hypocritical to me.

Honestly, you need to really look hard at the RoadRunner compared to the HPT RTT 'solution'. While the stuff from HPT does somewhat get the job done, it is like comparing a Cessna to an SR71. They aren't even remotely even in the same league as far as what their capabilities are. IMHO the only time where the RTT might be 'better' is on something like a Cadillac CTS-V where it is a total bitch to remove the PCM. Also if you leave the HPT RTT OS in your computer you have effectively locked out all other tuning software packages. If you are doing this for a customer they might leave mad if they find out they can't get in their own computer with whatever software they happen to be using if it isn't HPT.

I guess I am touchy from the aspect that I don't like people taking swipes, jokes, snide comments, or whatever you want to call it, behind someones back while asking them for help.
