Summary of change:
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 [http://shop.vems.hu/catalog/product_info.php?cPath=1_15&products_id=93 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? http://folk.ntnu.no/sathern/vems/underside_resized_redcircle_blueline.JPG or electrically the same 18V transient diode, but SMB footprint for same traces: http://folk.ntnu.no/sathern/vems/topside_close_resized_greencircle.JPG 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: http://folk.ntnu.no/sathern/vems/topside_resized_flyback.JPG Fourth http://folk.ntnu.no/sathern/vems/trigger_resized_bluelines.JPG '''correct for VR'''. confirmed Secondary hall needs nothing ! '''It still needs the cable on the underside of the board?(blue one below)''' 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) http://folk.ntnu.no/sathern/vems/underside_resized_wires.JPG '''confirmed''', the brown ground connection is fine there 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!''' ''' 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?''' ''' Is it any other soldering I have forgotten?other than MAP and econoseals of cousre'''
