Location: An island off southern Tasmania. | Today I had some time to play with the first ever reflashed 380 Bosch ECU.
Our good friend Stas and I have been sending each other stuff in the background.
Stas has done a terrific job in finding all the necessary information to make this possible.
My only involvement was to send him a 380 ECU that I had taken out of one of my 380's.
It's been months but at last we have one here in Australia to test. |

Location: An island off southern Tasmania. | How did it go?
Took it out of the packet and plugged it in.
Of course...the car will not start, so got the Mitsubishi MUT3 tool and laptop and usb cable...etc etc etc
The key for the car needed to be programmed.
I grabbed the key from the other ECU and with a few taps of the keyboard key is programmed and car starts right away.
This was a good sign........(By the way any key can be programmed to any ECU as long as you know how to do it, not like reported on some magna forums...so don't throw your old 380 keys away)
First thing I noticed was Oh Oh...air bag deployment warning light lit....
The ONLY way to clear this light is with a MUT3...therefore you cannot use one of Stas modded ECU's without access to a MUT3.
After airbag warning light cleared all looked great.
Started her up and pulled the front oxygen sensor connector apart.
happy days...NO ANNOYING CEL
If nothing else this was great news.
So took her for a drive to see if everything works normally.
Stas, the car drives good, I only took her for about 10 kilometers but all seemed very good and no bugs.
Next we see what other changes we can make.

Location: Russia, Perm | Happy for you. I think you have not tasted this product. The main value of this acceleration that he gives. Do not forget to press the gas pedal. Try to start from a standstill to 100. Can make a video acceleration. |

I want to say. Reflash does not affect air bags. Air bags have their own ECU. In ECU engine does not contain information for airbags. So either your car already contained this error. |

This car does not have turbo or supercharger.
But I did notice it was a little bit faster, but hard for me to be amazed because my turbo car is very fast.
Still this ECU is big improvement and proof that it can be reflashed. |

Location: Russia, Perm | I wrote to you, that this was an reflash is average. To obtain a unique product requires reflash on the spot. Besides, as far as I understand, your turbo is not fully configured. Using the reflash you can fully customize any turbo or supercharger to the factory ECU. |

Location: Russia, Perm | You can make a video acceleration 0 - 100 km/h ? Just press the pedal to the metal. It will show how many seconds. Of course, ideally, is to put two cars next. One stock, another reflash. And give them a head start on 400 meters. Then you all will see. |

I will do that in the next two days. |

Location: Russia, Perm | I want to say also that this reflash is working with LPG. LPG has a higher octane number 114. In the firmware connected octane-correction. It gives a good result. |

Location: NEWPORT QLD | Hi Stas
I have LPG. Does this mean your modifications will allow the ECU to adapt timing etc to suit 114 Octane rating of LPG, thus allowing more aggressive ignition timing etc?

Location: Russia, Perm | Yes, LPG is a very good result. In Russia many people who have LPG, made a reflash. Mostly we use gas equipment of Italian companies (fourth generation). Of course firmware for LPG is slightly different from a gasoline. In General, however, they are the same. |

Location: An island off southern Tasmania. | I tried the reflashed ECU in my GT today.
There must be an incompatibility because it sounded like it was misfiring constantly.
An unmodified ECU works perfectly however.
Dunno...but can't use it, maybe it has gone faulty?

Location: Russia, Perm | ^^^ Judging by the video does not work one cylinder. Check the connections at the ignition coils. Reflash makes no changes to the order of the cylinder. On the other car and it works. Look for the cause in the engine.
First, define a cylinder does not work. To do so, during idling, alternately disconnect the ignition coil. Do not worry, nothing will burn and not be worse. Working cylinders will reduce momentum when disconnecting. Not working cylinder will not give the change of revolutions. Next, remove the spark plug. Possible send photos. Recommend to conduct the test compression. Name the figures of compression in the cylinders. Next on the circumstances. |

I did many tests, I put in stock ecu it works perfect, I put in reflashed and it misses one cylinder....I do it all 3 times and same result.
Like I said, maybe the ecu has gone faulty.
Or maybe because this is a turbo car with Link G4 ecu and bigger injectors etc that it doesn't like it.
Anyway, it doesn't matter because this car uses just one wideband oxygen sensor and other four are disconnected.
No need to check compression on motor, it is a new forged engine with 8.5 compression ratio etc.
I just wanted to test rpm maximum and speed limiter maximum. |

Location: Russia, Perm | I would strongly recommend you to test compression. Engine after bulkhead may show very different results. This is for your peace of mind. You understand me? Also this test you check the quality of the engine Assembly. It's not long. After that everything will fall into place. |

Location: Russia, Perm | By the way, for turbo engine this firmware does not work. For it will be very lean AFR. However, if it is idling, all cylinders should work. So I have, and the question arose as cylinders. Check for your own peace of mind.

Location: An island off southern Tasmania. | I tested it, it stops oxygen sensor check lights.
I could not see any other change in terms of anything else, so I decided that it was too expensive for just that.
To use it to tune would require an extraordinary amount of t0 and fro due to Stayer locking it up as tight as a fishes arse.
It would be going from a locked Bosch solution to a locked Stayer solution...no gain.
In was hoping that the road speed limiter was disabled and the rpm limiter disabled...but nope...
Real Pity...but something will come along soon enough....other people are working on it. |
