AutoCal's primary purpose is to provide GDP with a cost effective way to service their remote customers’ data logging and tuning requirements. Being small and lightweight, it is cost effective for workshops or individuals to purchase an AutoCal instead of the customer shipping their vehicle's controller to the workshop.

With things changing rapidly in the tuning world and the recent introduction of the MM3 tuner, I thought I'd throw up up a thread showing what I feel are true advantages the MM3 tuner has over the EFI Live Platform which includes their Autocal and V2 Flashscan devices.
I'll just merely break the ice here and invite others to state their opinions as well!EFI Live has been around for the Cummins for a while now. The tuning platform works quite well in capable hands. However their hardware is old and outdated. We know this from the storage capacity within the devices to hold tune files, the fact the newer trucks require a unlock from either a Bully Dog tuner or bench to use EFI Live, and also just the 1980's look and feel on the EFI Live hardware. Now many would argue that it works, and it does, but things must evolve to meet demands.
We must also note that EFI Live only goes back to 2006 for the Cummins and the 10-16 trucks only have a minimal amount of parameters mapped out for public use.Now the MM3!!!The MM3 is one high tech and powerful piece of hardware. It is a modern touch screen device. It can unlock the later ECMs for tuning, tune all Dodge/Ram Cummins trucks all the back to the 1998.5 VP model (with UDC Pro-RT tuning software) up to the 2016 year models (with UDC Pro-RT and Warp tuning softwares), and also serve as gauge monitoring station!
The MM3 comes with all necessary hardware and also can accept an optional EGT probe for EGT monitoring. The MM3 can be placed in a variety of tech modes that can provide the professional with a wealth of vehicle information as well as flash in recovery files to fix and alter ECM operations.As we I mentioned above the MM3 is not limited to one tuning software. It can use both UDC Pro-RT software and Warp tuning software.
This allows the tuner (both professional and novice) to tune all trucks back to the 1998.5 model and have full ECM control over the newer models where this becomes extremely important. Best of all, both tuning softwares are publicly available and you don't have to obtain base files from a variety of sources.its all right there for you in both UDC Pro-RT and Warp.UDC Pro-RT 1998.5 VP truckWarp 2016 Aisin PickupSome have argued recently that UDC Pro and Warp lack the same data logging power that EFI Live has.and this has been somewhat true. However I have been told that true 100% data logging is almost ready for UDC Pro/Warp users, which will put the MM3 solidly ahead!So here you have it in a nutshell! A lot has been brought to the table with the MM3 and more is to come with software advances! I can't say just yet what is coming the next 6 months, but the competition is going to blown away!RayDouble R Diesel, LLC. I'm just throwing rough times out here, but the bully can take up to an hour to unlock the ecm in 13-16 trucks, then the efi takes another 15 minutes, and is quite complicated. MM3 unlocks and loads tuning in like 10 minutes, and is much more user friendly and forgiving.
The number of tunes is endless on MM3, and limited to 4 or 5 with efi. An MM3 is not locked to a single one companies tuning, and can actually have tunes from multiple tuners installed on it. You can purchase multiple vins to tune up to 4 trucks with one MM3, which is unlike autocal one truck use. I can go on and on but I better go to work. Also to talk about data logs a bit. I'll mention the darkside a bit.
If this was there, it would have 10 post already about not having data logging. Well ultra came out little over a year ago. And back then it was oh you don't have trans tuning. We got that, and then it was oh you don't have custom tuning.
We got that and it's down to oh you don't have data logging. Well I'm thinking it's safe to say we're gonna get that too lol. In just a little over a year we got trans tuning, custom tuning, RT, and the introduction of MM3. Safe to say if they say data logging is coming, it is!

Please use at your own risk!Scan Tool use for starting your truck, how a Duramax idles, and balance ratesOne of the rumors about using EFILive® is that you will blow things up if you don't know what you’re doing. While his can happen, it is not likely for someone who becomes familiar with data logging before they start tuning.
Nobody has ever hurt an engine or transmission with a data logger. Data logging is the perfect way to become familiar with your vehicle while not changing anything that can break parts. The best part, the scan tool is included with the EFILive® software!You should download and read the scan tool manual from EFILive®:Or find it at Start=Programs=EFILive=V7.5=Documents=Scan Tool ManualHere is another tutorial regarding basic logging of a vehicle:Or from the Scan Tool choose Help=Tutorials=Scan Tool TutorialThe parameters you log are called PIDs. Here is some information about PIDs:Diesels need a few things to run. Air, fuel, and compression come to the top of my head.
Because a Duramax engine is controlled by electronics, it needs to monitor a lot of the engines operating parameters so it knows how to keep the engine runningFor a Duramax to start, it uses the cam sensor as a reference to crank position so it knows which cylinders are coming up on compression. This enables the ECM to know which injector to start with. Once the computer gets a signal from the cam sensor, it begins the firing sequence. From then on the ECM monitors the crank position sensor to maintain the firing order. The cam sensor is only used to get the motor started.Why is this important? Because you have some cam and crank sensor pulses missed PIDs you can log.
This information can help you diagnose no start conditions. I've seen trucks that don't set cam or crank sensor codes have issues that can only be found by logging these PIDs. It's a good idea to become familiar with these PIDs when your truck is in good running order, that way the frustration of a truck that doesn't start does not get in the way of your finding the problem.The cam and crank sensors are located on the front of the motor near the fan pulley and the crank pulley (balancer). The cam sensor is the upper one, the crank sensor is the lower one.
The Duramax uses the crank sensor at idle to monitor the instantaneous RPM. The computer checks the RPM before and after each ignition event and it adjusts the injection amount of each cylinder to make the engines idle smooth.The difference between the commanded amount and the adjusted amount of fuel is described as the balance rate. When logging balance rates, you will see all zeros if the computer is not in idle mode. The Duramax computer (ECM) can't monitor balance rates if it is above idle or in fuel enrichment mode.When in idle mode, you will see balance rate values between 15 and -15. These values represent the amount of fuel that needs to be added or subtracted from each cylinder to maintain a consistent idle rpm and consistent crank speed.
A negative value means the computer is taking fuel away from that cylinder to maintain a smooth idle. A positive value means the computer is adding fuel to maintain a smooth idle.A properly running engine will have values in the +3 to -3 range. Values above 3 and below -3 should be watched closely. Values above 6 and below -6 generally indicate some sort of injector or compression problem. Since the motor needs fuel, air, and compression to run, one can assume that there is a problem with at least one of those items. I’d say your balance rate reading is suspect.Low compression on a cylinder will likely cause the ECM to call for more fuel to get it to keep up with the rest of the cylinders. A leaking injector might let too much fuel into a cylinder so it fires with more force than the others causing the ECM to lower the balance rate.
Balance rates can be checked with hot or cold coolant temps. You should check them both neutral and in gear. Idling in gear will put some load on the engine and might allow a sneaky condition to show its ugly face.
