I am new to this website but also to the standalone ECU world.
I will try to explain the project as much as posible. So put your seatbelt on, and stay with me !
So, the engine is originaly a 1.6L installed in a Alpine A310. (pictures to come next month)
My friend, has used some of his magic to transform it into an almost 2.1L.
He was given a S60PRO ECU as well as a Jenvey ITB kit and a wideband lambda sensor.
The problem is : he doesn't know a lot about ECU, so I offered to help him.
Here I am, with a S60PRO and an engine I still haven't seen and I need to make it run.
That is for me a very exciting challenge considering that I am an engine engineer.
My idea was :
- use Clio 172 ignition coils and injectors as we are aiming for the same power output
- use Clio 172 base map as a starter and modify the values from there
- I also already bought the folloling sensors :
- Bosch 0 261 230 340 Temperature and Pressure Combined sensor for Oil and Fuel circuits
- Bosch 0 280 130 039 Temperature sensor for Coolant Temperature
- Bosch 0 281 002 634 Camshaft position sensor (hall effect)
- Bosch 0 261 230 549 Temperature sensor for Intake air
- Bosch 0 280 122 001 TPS
- Bosch 0 261 210 139 Crankshaft position sensor (hall effect)
- Bosch 0 280 130 026 Temperature snesor for intake air (backup sensor)
So I think that regarding the hardware I have everything I need.
(pullup/pulldown resistances will be determined a bit later on)
Now the question is : how do I calibrate this engine ?!?
Here is my action plan :
- Instal all the sensors on the engine and make sure temperature and pressure sensors read correctly
- Measure cranshaft position sensor relative to TDC, enter the parameters in DTA, make sure it reads correctly
- Install intake pressure sensor (link all intake runners) and pull the car with different engine speed/load to get a correspondance between throttle position and intake pressure
- Measure injectors deadtime and use Excel sheet to determine fuel quantity using previously measured intake pressue
- Set basic ignition timing
I will try to get some pictures of the car and the engine as soon as I can.
