5% is OK for most stuff, but MF 1% are better in every way and cheap enough to not care.
Would making a sub forum in the hardware section for TA builds / TA hardware be a good idea
It's something that I've been considering for a while. I guess you know the answer if you're reading this :-)
i plan to take tons of pictures and document everything , also will test out anything thats needed along the way. i would not mind this being copied into there either ~
Cool! I look forward to it, EVERYONE loves lots of pics :-)
6x cop coils
Type?
6x high imp injectors ( might need to double check ) also have 6x volvo t6 injectors
This is important. If they are high Z, then it's one FET each. If they are low Z then it's one jbperf.com injector driver board kit (58usd each) per set of 4 or part thereof. IE, you'd need two of those kits.
60-2 hall sensor crank wheel ( motor has also a front 60-2 wheel bmw has removed in newer versions )
You'll only use one of them (either is fine) and you'll need a VR conditioner for that. You have a choice between an LM1815 and a jbperf dual VR max99xx based board. The latter is much better, but a bit pricey, the former is diyable (jbperf board is smd and preassembled for diy use).
cam signal not supported (yet! )
Second channel of the jbperf board could handle this.
3 - wire iac
Two FETs and some logic circuits just like ravage.
heated maf ( i have still but plan to use map but can use for testing )
Sure, if you want to test, but plan on waiting for a while, or doing MAP first.
map sensor ( need to find one or take the one from the ms2 ... )
See simis' threads in user rides for advice on this.
could hook up 2x narrorband o2 sensors for testing , each would measure 3 cyl on each side of the 6 )
If you want, 8 spare ADC pins for GP logging and inputs such as that.
14point7 wideband kit ~
Which?
2x knock sensors are also present ( willing to test these out too )
You'll need to construct a circuit for this with specific ICs etc. Save this for a later more advance stage.
honestly if i end up with a running car anyone can build this~
You can and will, if you put in the time and effort and listen to advice from the right people. And yes, anyone can :-)
Re resistors, you'll need 2.4k, 1k, 470ohm, 100k, and perhaps others. You may need 100 ohm depending on your coil/ignition.
Re caps, what Jared said :-) 0.1uF ceramic, 0.22uF ceramic, 10uF tantalum should cover it. You'll only need 2 of the tants, they're pricey.
Re regs, use LM2937 or LM2940, just one is enough, you need to heatsink this and all of the FETs too. A strip of alloy is enough.
I strongly recommend LEDs on all of your IO if the chips involves support it, even if you need to buffer it (like the output of the max chip for example).
What Jared said about the schottky situation is correct. Preliminary results from simis indicate that it's fine to use what he got.

As long as it starts with VNP and is 5amp or greater and 40V clamp or more, it's fine. I strongly recommend.... which ever one you can get
cheaper :-) The 14n04 stuff is newer and better, and more expensive, usually. I'd get VNP10N07 if I had easy access to them
cheaper than the others.
Prelude, sounds like you're getting screwed on the VNP situation, check other suppliers, 2usd each is about the norm, maybe less. You'll need 1+2+6+spares (fp relay + idle + injectors + spares).

Yes.
i will need to wire everything as 6x spark and 6x fuel on the ecu connector side for the wiring harness ~ this may be interesting
Bring all of the wires all the way back to the PCB. Use one fet or one ignition drive per injector or coil. One cpu pin will drive one line driver chip which will drive two output circuits.
Speaking of which, get at least 16 channels of line driver outputs. If you use a backwards ign setup you can swap 6 of those to XOR chips, waiting to see what you have for ign before advising further.
getting tired ~ i did find a company selling VNP20N07-E for $1.67 each with free ground shipping ~
exactly!
Fred.
