Motec MLS - LS1 specific ECU Anyone use one or have any experience with this LS1 specific Motec? I had an Autronic in my last car and I was amazed with it. Motec seems like the next step up and this one is very very reasonably priced at about $1000.
The compact and lightweight MLS is dedicated to Chevrolet LS1 and Lexus/Toyota V8s, providing a price competitive solution for this range of popular engines.
A derivative of the M4 engine management system, it has all the benefits of performance and reliability associated with this earlier generation ECU.
The DOS-based tuning software is efficient and easy to use with the same functionality as the M4 ECU Manager software.
Engine Tuning Features
*DOS-based ECU Manager tuning software
*Individual cylinder tuning of both fuel delivery and ignition timing
*3D fuel and ignition tables for engine mapping
* Table axis selectable from a range of channels
* Fully configurable axis points on fuel and ignition tables
* Chevrolet engines:
o Ref/Sync modes to cover the old and new trigger patterns for LS series of the modern V8 Chevrolet engines with 8 coils; mode 233 (24 crank teeth) and modes 81 or 83 (2 missing teeth; one per cycle)
o Ignition system needs to be wired and run in group fire mode using the 4 injector drivers with the coils configured as wasted spark (leaving 1 auxiliary output)
* Lexus/Toyota V8 twin distributor style 1UZFE engine:
o Multi-tooth Ref/Sync mode
o The number of coils needs to be clamped to 2 (leaving 3 auxiliary outputs)
*
Free access to wideband Lambda and data logging for initial tuning for the first 6 hours engine running time
Additional Distinct Features
* Capable of modern control functions, such as:
o Traction control
o Overrun boost enhancement (anti-lag)
o Gear change ignition cut (flat shifts)
o Boost control
o Nitrous injection
* Fully configurable sensor inputs including custom calibrations
* Transmitting data via RS232 bus
* Wideband Lambda measurement capability
* Integrated advanced diagnostics, including injector & crank trigger diagnostics
Data Acquisition
* Internal data logging (512 kB) with download via RS232
* State of the art i2 Standard data analysis software
Upgradable with optional functionality to make additional features available when you want them, activated through a simple password system. http://www.motec.com/mls/mlsoverview/

I've looked into them and even poked around in the software. While its capable of doing the job, you can get away with the factory PCM in 99% of applications. The software is very crude compared to EFI LIVE which is a huge turn off.
