my Alfa Milano MembersPage/KeithHargrove/AlfaMilano my Alfa spider MembersPage/KeithHargrove/AlfaSpider ''' VW COP ''' http://www.vems.hu/files/sly/cop_inch.jpg Too long for the 4cly http://www.vems.hu/files/sly/cop_spyder.jpg Looks like I can make it work for the V6 http://www.vems.hu/files/sly/cop_vs_75_OEM.jpg http://www.vems.hu/files/sly/cop_75_top.JPG http://www.vems.hu/files/sly/cop_75_side.jpg http://www.vems.hu/files/sly/75_v6.jpg The pinout if there is a power-NPN inside I think we will need to add a small NPN (2N3904), eg. on the IGBT pads: * the small NPN's Base goes to where the gate was (1k away from ign259's output pin) * Emitter need to go to a resistor (say 10..33 Ohm) then the COP pin 3 (driving the power-NPN's base) * and the Collector goes to power (+14V, same that powers the coil) Let me note that stepper driver could drive the NPN almost directly, through a resistor (and very fast!) if we allowed any digitalout()-pin for ignition in edis.c (not just the ign259 outputs). http://www.vems.hu/files/COILS_COPS_etc/vw_cop_06b905115e_sch.gif 1J0973724 might be the plug for the VW coil as vw etka lists them ---- '''Triggering''' I have been working on a easy way to retrofit older cars with no tiggers. The proposed GenBoard/InputTrigger setups below are optimized for fast startup (little time spent in cranking). "They are not simpler than the supported (ncyl/2*N - m) missing tooth crankwheel setup (like a vanilla 24-1, 36-1 or 60-2)," How is making a "Vanilla 24-1, 36-1 or 60-2" + some cam pickup(we need to know when to fire the coils and which cyl to inject to) simpler the breaking off 2 tabs and adding a hall. but with appropriate firmware support they can find out the engine position faster at cranking. Anyway, I like the documentation format. We need to explain the direct ign setups on DummyIgnition page (or rather subpages) in a similar way: * drawing - the 3D is especially nice (rotation direction is important in some cases!!) * explanation * advantages * disadvantages * config settings (if supported) ---- This is not the simplest for a 4 cyl. It is not?? OK what is simpler that will do seq. injection and drive the 4 coils? http://www.vems.hu/vems.hu/files/sly/4cyl.jpg The pickups are 180° apart. If the 2 pickups were ANDed it would look like a it had 4 tabs not 2 so with this we can see 8 edges one every 45° of the encoder or 90° crank We can add more tabs if we want. 4 tabs would give 22.5° on the encoder and 45° on the crank. With this we get: * Sync after one gap. * If a pickup dies we could still run. * Very simple to make and install in a old distributor or on a CAM * If the 90° is ok most Hall distributors could be retrofited by removing 2 tabs and adding a 2nd hall ---- This is a old example of a simple trigger for 6 cyl. http://www.vems.hu/vems.hu/files/sly/trig_w_b.gif http://www.vems.hu/vems.hu/files/sly/trig_w_a.gif The pickups are 60° apart. Pickup A is even. and pickup B is odd. With this I can get sync after the first Gap. So I will not have the crank and crank untill #1 comes around to get sync. also if one fails I should be able to still get sync after no more the 2 gaps (1 gap past the working pickup) and use softwate timing for the missing pickup. This can go ether on a cam or inside a distributor. ---- injector connectors http://www.machv.com/fuelincon.html $12 http://www.racetep.com/injcon.html $10 http://www.clewett.com/products/connector.htm $4.50 + $2.50 for 5 pins ($3.85each for 8) good pics here http://shop.store.yahoo.com/eagleday/ampconnectors.html tyco info http://catalog.tycoelectronics.com/TE/bin/TE.Connect?C=17458&M=FEAT&LG=1&I=13 827551-3(black type C) very common pin 927846-1 826008-1(grey typa A) 826008-5 (black) 825414-1(grey type b) the -x is the color ---- injectors to buy http://www.fiveomotorsport.com/Injector_SetsBMW.asp ---- http://www.dune-buggy.com/turbo/partslist.htm more info ---- http://www.vems.hu/files/sly/megasquirt200507080255.msq http://sly.gotdns.com/images/scope.gif ---- temp notes ||TEMP||MAT MSD||CLT Bosch|| ||21.1°C|| 2.285K||2.4K|| ||30°C||2.285K||1.7K|| ||40°C||1.5K||1.2K|| ||50°C||985||836|| ||60°C||675||600|| ||70°C||470||435|| ||80°C||336||330|| ||85°C||286||285||
