Bill of Materials

First draft of the Bill of Materials for the Webshop order. Any corrections or suggestions would be appreciated.

It is divided up into stages of the project as defined on MembersPage/CharlieKemp. Although it isn't as clear as it could be, it helps me to see how the project will progress.

Stage one:$FlgChr1$FlgChr> Ignition control only with direct control of wasted spark coils, running from 36-1 wheel and VR primary trigger. Still running carb at this stage. Manifold pressure only for calculating engine load.

Parts required:$FlgChr2$FlgChr> 1x Genboard$FlgChr3$FlgChr> 1x Econoseal 18-PCB $FlgChr4$FlgChr> 1x Econoseal 36-PCB$FlgChr5$FlgChr> 1x Econoseal 18-Wire side$FlgChr6$FlgChr> 1x Econoseal 36-Wire side$FlgChr7$FlgChr> 1x Alubos front plate - 3 small holes option$FlgChr8$FlgChr> 1x Alubos back plate - no extra holes$FlgChr9$FlgChr> 1x Alubos gaskets$FlgChr10$FlgChr> 1x Alubos case$FlgChr11$FlgChr> 1x LCD$FlgChr12$FlgChr> 1x 250kPa MAP sensor $FlgChr13$FlgChr> 1x VIV6464 Pneumatic connector$FlgChr14$FlgChr> 1x MV64 Pneumatic connector$FlgChr15$FlgChr> 1x Pneumatic tube$FlgChr16$FlgChr> 2x IGBT TO220 ignition drivers

Notes:$FlgChr17$FlgChr> A little confused about the clamping plates. I think they hold the ignition and injector drivers in place. Is this right? If so, how many do I need?

Stage two:$FlgChr18$FlgChr> Implement WBO2 and EGT sensing (and knock?). Due to peculiarities of 5 port head and siamesed ports, 2 channels would be desirable. Knock sensing is described as "For experts only" as "improper use only gives a false sense of security". However, I would be happier damaging this engine through knocking, rather than the next (more expensive) one, so can see the benefit of making it work at this stage.

Parts required:$FlgChr19$FlgChr> 2x Wideband O2 sensor$FlgChr20$FlgChr> 2x Wideband connector$FlgChr21$FlgChr> 2x Injector or WBO2 heater driver$FlgChr22$FlgChr> 2x EGT sensor - 6mm, no connector$FlgChr23$FlgChr> 2x EGT input amplifier$FlgChr24$FlgChr> 2x Panel mount K-thermocouple connectors$FlgChr25$FlgChr> 1X Bosch Knock sensor$FlgChr26$FlgChr> 1x Dual channel knock sensor interface

Notes:$FlgChr27$FlgChr> Is it worth having 2 channel knock sensing?

Stage three:$FlgChr28$FlgChr> Single point injection.

Parts required:$FlgChr29$FlgChr> 1x MAT sensor$FlgChr30$FlgChr> 1x Injector or WBO2 heater driver$FlgChr31$FlgChr> 1x Output for driving fuel pump

Notes:$FlgChr32$FlgChr> Presumably the output for driving the fuel pump is another injector driver???

Stage 4:$FlgChr33$FlgChr> Multipoint injection either with 5 port head or BMW K-head. Will need cam phase sensor.

Parts required:$FlgChr34$FlgChr> 4x Injector drivers (i.e. 3 more)$FlgChr35$FlgChr> 1x Additional VR or coil interface

Notes:$FlgChr36$FlgChr> Not sure if secondary trigger will be VR or Hall so not sure about this yet. What do the MPi Minis use? Where is it mounted?
