As first I'm going to install it on my 2.0 4cyl, I want to use my current setup for ignition:
- 36-1 with VR sensor and MAX9926
- Wasted spark coils direct drive.
In future V6 engine, as it has EDIS, Fred told me to start using EDIS as base as should be easyer, and change in a future to COP and seq inj when having XGATE working in firmware.
So, for the V6 engine no problem, EDIS could be the ignitor. But for my current engine I need two coil drivers. Now I'm using a pair of BIP373.
Which of the following solutions do you recommend me?
- pair of BIP373 (installed in a box on the engine and not in the board like MS). (
http://www.aliexpress.com/item/BIP373-T ... 22921.html) - around 20 days of shipping
- another pair of fets easier to found here.
- commercial device from junkyard (I need to know from which car remove)

Preferred:
1) OEM/Commercial device(s) from junk yard, almost any 90s car will be fine, consider taking enough equipment to test them if you're unsure.
2) IGBTs designed for ignition from a number of semi conductor makers.
3) BIP373 from China = scary/fake?
4) FETs do NOT work, and can NOT be used.
Also:
EDIS mode doesn't exist yet, you'd be working with me to develop it.
Fred.

Ok, I will try to find some OEM devices, but I think is not easy, as most of them will be of EDIS type or similar, or you know any common car where I can get from it?

Singles with just 3 terminals, doubles with just 5, quads with just 9, should be OK. Stuff a selection in your socks :-p Or measure them. Bosch do a common 4 cylinder one. There is info on the M$ site:

And others that are similar. Get a dumb module that is dwelling while the inputs are high and you're good.

ok thanks. I will try to find one of those.
My current board state:
6 injection mosfets and their leds (green color) were soldered. Didn't try yet.
I think I will remove that fuse, as it takes a lot of valious space

What is that big black thing? :-o If it's a fuse, what is it doing here? Put your 10A fuse at the beginning of the supply wire on the far side of the relay near the battery. For DIY stuff, don't bother fusing your 5V output for TPS/MAP.

ok, perfect, removed it
not very good looking welds and very close, but there aren't short-circuits. Anyway I will double or triple check before trying in the car.
current state:
Code: Select all
Main board
- MAT sensor circuit - DONE
- CLT sensor circuit - DONE
- MAP sensor and circuit - DONE
- TPS sensor circuit - DONE
- O2 sensor circuit - DONE
- MAX9926 and circuit (2 inputs) - PENDING. 0% DONE
- 6 mosfets to control high-Z inj - DONE
- 6 ignition outputs (with EXOR) - PENDING. ~50% DONE
- 3 mosfets (idle,fuel pump,boost)- PENDING. 0% DONE
- Wiring from IO MCU pins to IO's - PENDING. ~10 % DONE
- connectors - PENDING. 0% DONE
- temporal adaptor to DB37 - PENDING. 0% DONE
-AUX board - 0%
- 1 MAP baro sensor and circuit
- 1 MAP differential accross IC
- 2-3 aux temp sensor circuits
- Launch control circuit
- Another things I'd like in a future to install.
- Knock detection aux board - 50%. (Only tested SPI comms with arduino).
Until monday I can't work more. But next week will try to finish the main board goals.

One comment: Those regulators WILL fail at some point from vibration and work hardening. IE, the solder joints will crack and go dry. No problem short term, and maybe they'll last till you can get a proper board, but be aware of it.
Good work :-)

probably you are right. I think I can put a solder joint on the sinks to avoid vibration or use another type of sink.
