this week ill be swapping out my MAF setup for a 730 SD ecm. while im in the process of doing that i'd like to get all of the stuff that i will need to use VE master to get me started.

can someone that has used VE master give me a rundown of what i will need and maybe even a step by step on how to use it. i did a search and really didnt find anything like this. any help will be greatly appreciated. thanks

 

VEMaster is very easy to use.

Let your car warm up to operating temp.
Start up TTS' Datamaster
Take a nice long drive recording data.
Save your data.
Open VEMaster.
Select your ECM Type (8D)
Select your logged data file
Select the BIN you want to modify
Input your target BLM
Input the maximum RPM you want to scan.
Click Process.

Lather, rinse, repeat. Very easy and it really does work.

I"ve been using ve master and it works great. Made 3 runs and changes now and things are really beginning to shape up... Hey question.. can't you computer gurus (probably spelled wrong), make a program to do just about the same thing with the timing curve?.. That would be awesome.

 

Timing is a function in part of fueling.

The oem ecm is clever enough get Stoic out of a switching O2 but that's real genius.

The best you could do with any normal feedback from a knock sensor is going to take you to detonation limted tuning which is risky on a high HP engine.

Now with torque sensiing or ion detection you could do something along those lines, but that's expensive technology so far.

 

Figured i would expand on that. I've had good luck with 20 - 30 minute chunks of datamaster logging. One time i had over an hour of data saved and VEmaster wouldn't do anything with it.

While driving you want to make sure you cover a good RPM and load range. Helps to have aggressive TCC tables, or a manual switch to do high load lower RPM stuff.

Also helps to dial in the BLM cell RPM boundaries to something more logical for how you drive.

Only other important thing to know is that you have to go back in the bin by hand and clean it up after VEmaster hits it. VEmaster won't make it pretty, and has no problems doing things that make no sense, like having higher VE in a mid-load area then high load. Thats because it does correction based on BLM cell only, so if you collect data at one end of a cell, it might say want to add a few percent, but the high end of that cell might have been dead on, and likewise the next higher cell. After 2-3 passes though you'll get an eye for what is really going on.

 

I noticed in Vemaster it says to use a Tunercat .bin. I always though a .bin was a .bin. So is tunercat required with vemaster?

 

No you don't need TC, i have no idea why it calls it a tunercat file. Probably because most people are dumb so he figured he'd call it by what you'd use to open the file.
