The end user makes adjustments through the can gage. It adaptively learns fuel, timing, boost etc... so you don't have to go in and make adjustments through a laptop interface like you have had to in the past. The Can gage allows you to make boost changes, pump gas/race gas changes... etc..

i would definitely keep the VTC at stock settings cause thats what we run. i wouldnt want to lose power over stock stuff.

Remember these are all pre-production units that are being hand built to each specific application, meaning they are doing all the wiring, making all of the plugs, and adapting everything to each vehicle and testing it. As you all saw in the other thread (Turbonetics/PowerLab VTC Testing) they now have control over the VTC and will be used in all of the upcoming testing.
We had the opportunity to test a pre-production ProEFI unit on our Greddy car which furthers the development process and in turn will allow the entire community to have another great option as far as ems goes

I know you had tested my car with the proefi a bit before the results were posted, and i knew of the greddy run too but again...The intend of these threads is to clearly highlight the capabilities of VTC(how much more power you can make and improve spool time) and the ability of pro-efi /tune the to handle fuel smoothly(smoothing 0) at high boost dyno run after dyno run, as well as show how much power these cars are making on a dynojet SAE .
Most people will probably leave the cam timing stock with this units unless they have some "wild" cams....up to the tuner/end-user; but regardless you have the option to and you can clearly see what are the advantages of it with pro-efi

Honestly, you just tell the EFI what you have in terms of injector size, and what AFR you want and it does everything else??? That almost seems too easy. So what do we need tuners for??? Just kidding? WOW!!! This thing is amazing.
There has to be more to it...
Nice Job.

Thats what ProEFI is going to change about tuning, alot of people have been asking "well what does the interface look like", "what will i be able to tune", "is it going to be locked or unlocked" etc. And the answer to that is that none of it will have to be accessible since you won't have to tune anything. Things that you might want to tweak later on like Boost Control / Traction Control / Two Step etc.. will be able to be adjusted.

How VE is calculated:
As for how v.e. is calculated... the answer is mathematically!
V.e. is calculated off of swept cylinder volume, number of cylinders, combustion events per rev (i.e. 2 stroke or 4 stroke.) Map pressure, v.e. table, exhaust back pressure, iat, coolant temp, throttle rate of change, and a few other things.
It is true speed density or mass air. By TRUE speed density, I mean that the mass of air is actually calculated with all the things I mentioned above... the AEM is NOT speed density... it is alpha N with a pressure lookup table, as are most all stand alones.
---------------------------------------------------------------
Fuel pressure compensation.
With the simple addition of a fuel pressure sensor, the computer will monitor and compensate for various fuel pressure. Lets say that you have a pump that is tired and your fuel pressure is not rising 1-1 any more. The computer will know and add necessary fuel. Also if the pressure really gets unstable causing the computer to add too much pulse width, it will trigger a check engine light. It can also be set to initiate fuel cut, turn off the boost control, shut off NOS and lower the rev limiter. These safe guards can be triggered by the fuel pressure alone, by O2 activity or a number of other things!!
Because of the high speed knock control strategies of theis computer, it can compesate for octane changes.... Of course you stil have to keep your boost levels in check with the octane that you are running!! But lets say that you normally run 93 octane and on a trip you come across a pump that only has 89 octane, the computer will be able to adapt.
You can add a toggle switch to trigger high octane, medium octane and low octane maps!!
---------------------------------------------------------------
Boost Control Strategies
Will be able to utilize dual solenoids to control pressure to both the top and bottom ports on any wastegate. This will give you VERY accurate control!!
Will be able to control boost by speed.
Will be able to control boost by time. Therefore if you spin the tires, and the vehicle speed sensor puts the boost map into a zone for higher boost.... the computer will know that it is wrong and hold the boost down until a certain amount of time.
Will control boost based on traction control. Traction control will be based on wheel speed differential!!
This computer will also know what gear you are in by simply entering gear ratios from the service manual, rear end ratio and tire size!!
Also with the addition of a special fuel sensor ( one that the factory flex fuel cars use) the computer will know if you run E85, or regular gas, or a mix and adjust accordingly!! Of course this has to be setup but the computer certainly has the ability!!

Just play with boost control , traction control , two step etc.... ????????

but the first dyno VTC was completly dissabeled... and thats why the car looked like that.... that got completly solved once vtc was enabeled
