MoTeC v3.3 software released!

Finally!!

After a long time in beta, MoTeC has finally released the v3 software. This is the ECU software to end all ECU software debates.

Let's talk about the basics first: fuel and spark tables. Pre-v3, you could have 40x21 tables. Total of 840 points, more than enough for most. With v3, you can have 40x24 for fuel, and 55x35 for spark. That's only for 3D tables.

You can now specify 4D tables for fuel and spark. In a "classic" EFI setup you get 3 dimensions, usually RPM vs load (spark)/efficiency (fuel), and the tuner specifies the third dimension which is the actual spark advance or amount of fuel injected. With a 4D table you have one more parameter to work with. This may be gear, throttle position, MAP, MAP/EMAP, so on and so forth. You can even use your own user-defined channel.

For 4D fuel, you can have up to 11 points for the 4th dimension, with 3D tables of 16x11. For spark, you can choose either 11 sets of tables of 16x11 (just like fuel), or 6 tables of 40x16(!). The downside to the latter is that the spark resolution is in steps of 0.2 deg.

You also get to decide not just the number and resolution of sites ("breakpoints", in AEM parlance) in practically any table, but also get to assign channels to either x- and/or y-axis. I'm unaware of any other mass-market ECU software on the market that does this right now.

You can also perform ref-sync capture in the software, obviating the need for an oscilloscope when working on unknown crank-trigger systems.

Major enhancements in the input setup screens.

Major changes in boost-, lambda-, traction-, idle-, nitrous- and cam control. 3D RPM limit maps. Revamped accel/decel fuel and spark maps. The list goes on and on.

This software is going to remain the gold standard by which others are judged for the forseeable future.
