Vcm Suite / Autotechnica Tuning

[Dale@CHE]

vcm have live tuning on LS1 PCM with NO EXTRA hardware... and it works a treat...

im sure they are more concerned at the moment with getting FG support and the rest of the BA/BF calabrations sorted and then going public, then Dodge support before looking at ford live tuning...

That's great to hear

The tuner I know must have an older version, as he prefers another brand to do his GM tuning, Thanks Dale

[Dale@CHE]

its been avaliable for over 12 months now from memory, anyway this isnt a LS1 tuning thread

[shaneo_1]

I had been waiting for a while now for my tuner to get this software, as I dont need to travel 4 hrs for a tune.

my tuner pluged the software into my BF and wouldnt read it, then after sending codes away almost every week for a few weeks they have over come it and now it reads my ecu, which I am very pleased about. so a tune in the next following weeks.

Any software with live tuning would be very interesting. Keen to hear more if there are any out there?

[R-SPEC]

for example..

You're making it look like tuning the car using the VCM software has somehow given it more power. That graph shows tuner A and tuner B.

A custom tune using VCM software as opposed to a custom tune using SCT software is not comparable in a graph format but rather how it is used by the tuner.

Plus, I highly doubt you'll ever see live tuning on these PCMs.

peak boost is the same around 3500rpm and 13psi but after that there was some adjustments done to the boost with boost now holding 11psi not dropping back to 9psi like the previous tune

from memory on the same boost it went 284rwkw.

I didnt tune the SCT box, they were done somewhere else in sydney..

I have attached a sheet with boost on it, ill post a compare between the 2 on monday and one with the boost at the same levels.

A Dyno graph comparison on a car tuned by 2 different tuners isnt a way of comparing software. As Ratter has mentioned previous, All these tools, Be it, SCT, Sniper, or VCM, Only provide access to Tables within the PCM, nothing more, nothing less. Some software is easier to use, ie, VCM is very nicely presented, compared to Sniper, which will have you scrolling for months looking for that table.

You mention that boost control seems to hold 11psi, instead of 9psi, which can be influenced by manythings. Now, Since you didnt do the "SCT" tune, I can almost garentee your tuning techniques on a Turbo would be different to the workshop that tuned this vehicle previously.

Running a XR6 Turbo with a standard actuator will see anything from 9psi to 11psi up top, and even as high as 18psi running 100% wastegate duty cycle, the exhaust and intake setup make a huge different here, BUT, Since you done a back to back dyno run, It would indicate that the intake or exhaust was not changed, Only the tune was.

From a tuning perspective, as you know, changing AFR plays a affect in the amount of boost it can hold, as well as the amount of Spark being delivered asssuming the previous tune was running 100% wastegate duty

I just dont believe people should be Mislead to thinking that "X" Software instead of "Y" software was the contributing factor in why this car made more power compared to before.

But in saying that, If one software is easier to use over another piece of software, and helps a workshop tune more effectively, then so be it. But this is not the case here.

Also, About the live tuning.

Ford have dev pcms, which contain a device called a "M6" under the main microprocessor within the PCM itself. This device is basically a Memory Emulator. Its not flash memory (which is what your pcm contain now), but rather, RAM, which looses data when power is lost. But also changable without having to Erase the entire chip, or Banks of the chip prior to making a change.

Here is the link to the device. http://www.accuratetechnologies.com/en/pro...rs-257-254.html

Combined with the appropriate software also produced by Accurate Technologies, "VISION", Allows Real time changes, as well as Real time monitoring, Must faster than you can suck out of a OBD port using PIDS, OR DMR requests.

http://www.accuratetechnologies.com/en/pro...re-178-174.html Have a look at the screeen shot there.

Because our PCMs have Flash memory build into them, before any change can me bad to a spark table for instance, requires either a FULL erase of the chip, or a Sector erase, erasing a large block of the Flash Memory. For obvious reasons, your unable to do this live whilst the PCM is running the engine.

Further to this, Erasing flash memory, be it entire, or partial, can only be done via the Ford designed bootloader, Which is why when using a SCT box, you have to start the program process prior to turning your ignition on. The technical reason behind this is the SCT Flash box (or VCM, or Sniper) applies 18 volts to pin 13, known as the FEPS line. On Ignition sequence, the Processor looks for this, and switched to a bootloader mode if its detected. In the past, older pcms required 18 volts applied as old Flash memory needed a 18volt source for erasing.

gday gents,

the graph dale has posted is mine. tuned this morning in sydney.

the gap that is evident between my "custom" tune and what dale did for me today is extremely clear when driving it. I am not an ECU guru but the guy spent a good 3 hrs tuning my car only, not flashing "custom" tunes onto the PCM like a lot of tuners will.

I have more power, no boost spikes, and no lean outs (like I had before) and am making 301rwkw at 11 psi.

I am extremely happy with dales work at the current capability of HP Tuners. its only gonna get better boys..........this is the real thing

[Dagabond]

Guys dont try to sell it like its the ducks guts and better than SCT it wont work here, there are to many knowledgeable people that will pick it for a what it is....

A viable alternative nothing more.

[Erko]

^ spot on Dags. you are right. Its a viable alternative, and at the end of the day, the most important thing is the Tuner who knows what they are doing AND spends the time on YOUR car.
