EMS/Powertrain review thoughts

For 10yrs I been reviewing the best viable Engine Management Systems (EMS) for customers and their projects.

Customers tend to invest heavily in modifications, spending in excess of $3000USD in mods, while thinking less about EMS’ and their capabilities. Once such reason is due to the complexities of such key devices and how important there are.

Below are my thoughts on EMS determination:

  1. Ability to at an advance level, turn the knobs to effect critical engine operations
  2. Ability to accurately and precisely determine the next engine operation. The need for FPGA’s and possibly RISC processors for that, including precise coding for efficient software processing. The software that drives it all should be optimised for all of the hardware and the hardware optimised to work together efficiently and effectively; in a harmonious way.

    3. https://www.xilinx.com/video/hardware/what-is-the-difference-between-an-fpga-and-an-asic.html
  3. Strategies and analysis on Engine operations and management
  4. Support into known and hidden features to support the operations and management of engines and Powertrains. That is the ability to get customised firmware of software updates to you in the field. That implies the ability of the manufacture to execute change.
  5. Selective Scoping and high logging rate to capture events and operations

All of the above is achieve when manufactures are part of Engine Development like Life Racing/Syvecs, Motec, Pectel, Bosch and a few other top Powertrain manufactures.

First Autocross event – Trinidad

I been tuning some JDM STI cars in Trinidad way back and had the opportunity to take part in an autocross. Track is better for me and I hate such events. Either ways, I did and finally, I just gave up, throwing caution to the wind and enjoyed my last run ๐Ÿ™‚ bringing me into second place.

The car was tuned for racing, maximising torque, but no anti-lag at that time. Carberry GpN rom was not available at that time. So the boost will come on hard after lag, making it a little difficult in turns etc. In addition,ย the car had on stock suspension.

Its now tuned ๐Ÿ™‚

Please read my review about XRT. I recommend XRT for all you needing a perfect tune.

This car is from what I know the only one in Europe at this time. Only made in 401 pcs year 2002.
As this engine is a hand built STI engine for minimum 100 octane is was very important to get it tuned for swedish 98 octane and also some improvement.
I have been following openecu forums since 2007 and ONE guy have always stand out in lots of posts. Mr. Edward!
So when car was ordered I contacted Ed and asked if could help me tune the car.
When the car was road legal we started the tune.

The support from Ed is totally outstanding. He responds to question almost 24 hours a day. He send me new updated roms faster than I could flash and log. His commitment is unique. He is more than a tuner, he is also a friend and a listener. Think that is extremely unique. He care about you and the car!

Off course the tune is also outstanding. The car is now starting more easily, idle more smooth, better respond, better engine sound, more power low and high. This tune is what Subaru should have done. Very Impressive. I can recommend all you that need a real good tune XRT and Mr. Edward.
