Hi,

I am trying to build my V3.3 board from a kit as I see it as a good way to learn a bit as I go. I have help from a very experienced "solderer", so that bit should go okay. Guess it will arrise some questions on here soon:)

A little bit about the project

It is a heavy cammed 16V 1293 cc engine with individual TBs.

The sensors I am going to have are

-tps

-inlet temp

-map (internal)

-wideband lambda

-water temp

-Vr crank

-hall (cam)

people recommend AlphaN, I agree now, after reading about it.


These could be used in the step by step assembly guide

First, topside of board between the two econoseal connectors.

A [18V transient diode can be installed] (check your rescue kit, maybe included: marked sg like 1.5k18V):

FOLLOW up, this one is not included, but guess I should find it at elfa or similar. I have two of the 30V though.

Where the blue line is, should I have something there?

A: only needed if you have a stepper

or electrically the same 18V transient diode, but SMB footprint for same traces:

Q_ Second, flyback. I have high Z injectors and plan to use a 30V diode in the flyback path. Solder the 30V diode as the line in the picture, yes:

Fourth

correct for VR. confirmed

Secondary hall needs nothing !

It still needs the cable on the underside of the board?(blue one below)

A: as stated in build doc

Also here is a picture of wires underneath the board

this is for

-PC connector (cyan)

-no one wire interface (red)

-MAP (yellow)

-secondary hall (blue)

-ground (brown)

confirmed, the brown ground connection is fine there

I have also read that when I am not going to use all FET/IGBT spots I have to install a short, where from and to?

Also I have four IGBT, two will be used for driving an EDIS coil (logiclevel) and the other two I dont know, maybe one for tacho.

I have 10 inj drivers. Guess these should be placed in the spots with blue circles. (the two with yellow inside is for WBO I have understood, I am going to use only one of them, but will install in both spots as I have enough drivers)

How do I choose if IGBTs its supposed to be logiclevel or power output?

logic level required no IGBT, only a short between the two spots closest to the EC-36.

Is it any other soldering I have forgotten?other than MAP and econoseals of cousre

Thanks, good questions (not empty questions, but signs of research => mostly just need confirmation, really good, keep up), good pics !

Thanks! The picture may be used by anyone who wants to!
