Please post in this thread if you are in principle interested in going in on a bulk buy of 10 or 20 of the initial FreeEMS PCB.

One post per person in this thread please.
If your interest is conditional upon various features please state that. Some things you may or may not care about :
- On board IGBT ignition drivers
- On board low Z injector drivers
- Thermistor self heating prevention :-p
- NO thermistor self heating prevention
- Current feedback circuitry on injectors
- NO current feedback circuitry on injectors
- ONLY SMD components
- ONLY TH components
- SMD components supported
- TH components supported
- X primary fuel channels required/preferred
- X ignition channels required/preferred
- X auxiliary low current low side drives preferred and required OnOff / PWM
- X auxiliary high current low side drives preferred and required OnOff / PWM
- How many boards?
My requirements are :
- Don't need - either
- Don't need - either
- Don't want - prefer not, but either
- Don't care - prefer not, but either
- Don't want - prefer not, layout dependent
- Undecided, layout dependent
- Won't buy
- Will buy
- Don't care - either
- Required
- 4 primary fuel channels prefer 6
- 4 LOW LEVEL ignition channels prefer 6
- prefer : 2 on/off for relays for fans no low current pwm
- prefer : 2 high current PWM for boost/idle, no high current on/off
- 1 or 2 depending on how much I like the design
Quote this message and edit away all the stuff except the main list and then run through it changing the words to your thoughts on the item.
To summarise for me :
1 or 2 boards
Must have 4 high Z fuel channels
Must have 4 low level ignition drivers
Must have through hole component layout
If the current feedback isn't dropped and it makes a mess of the layout I may be not be interested. Would prefer it wasn't there.
It is assumed that basic stuff like good power supplies and sensor inputs including at least 2 VR inputs, analog wbo2, air, water, tps, map, atmo, etc will be included by default. You don't need to worry about that sort of thing. If there is something you really care about that isn't on the list, please mention it clearly.
State your interest here!! :-)
It will be a little while before it goes to be printed, and a little while before we have usable code for it too this just a feeler to see what people are and aren't interested in buying and testing/using.
