 |
|
Hi all,
I'm new here and I'm considering buy a DTA S-serie ECU for my car.
Engine is a 6 cylinders in line.
I see on DTA web page that S60 ECU can work on grouped injection but don't found setup for this on manual and DTAswin software.
Anyone know how to do this ?
Thanks. |

Hi,
S60 can only run this engine grouped injection and wasted spark ignition.
The S80 will run up to 8 coils and 8 injectors sequentially if you have a cam sensor.
You need to tell the software what you want to set for your engine to suit the ECU you puchase.  |

Does your engine have a distributor? if so the S40 can do it.
If no distributor S60 with wasted spark can do it
Do you need anything trick cam control? |

I'm confused,
I want to work on semi-sequential injection, 2 or 3 injectors banks.
I don't have cam sensor. |

| You will need an S60 to run semi sequential injection on 6 cyls. but you will have to run wased spark ignition |

I see that S60 have 4 coils drivers, ignition not a problem.
I want to know method to use semi-sequential injection with this ECU.
I don't found it on manual and DTAsWin Software.
Thanks. |

it also has 4 injector drivers.
you just use 3 of them and pair the cylinders up to run wasted spark / semi-sequential fuelling.

Thank Roverdose,
I understand I use:
inj1 -> cyl 1-6
inj2 -> cyl 2-5
inj3 -> cyl 3-4
ignition firing order is: 1-5-3-6-2-4.
At fist time, want to use original distributor.
In this setup:
- Need a cam sensor ?
- Don't found setup for semi-sequential in DTASwin software ?
There only a page for full sequential injection.
Thanks for all. |

no need for a cam sensor.
if your not using the full sequential setup, the ecu defaults into semi sequential.

as your not using full sequential, the ecu wont use those settings.

that this I don't understand,

There are only two modes.
Sequential, or Group fire.
As you are not using sequential, it will use group fire.
People try and call batch/group fire many things like semi-sequential
it isnt, its group fire.
You dont need to worry about any settings. Just wire it up, and it works.

Hi stevieturbo,
that this mean in grouped mode all injectors are fired in the same time ? |

To be honest, I dont know exactly when they are fired. All I know is that it works !
Ive been using DTA for almost 10 years now with crank trigger only, on V8's with group fire.
ive never had any problems.
the only time group fire will become difficult, is if you are using very large injectors, on a small engine.
In those cases sequential becomes very important. as each engine is different, its hard to say when that is a problem though.
But that applies to any ecu, not just DTA.
