Summary of change:
Plug'n'play was a nice idea, but connectors are harder to find. A new ECU and a new loom to suit is easier. Land Rover made life good for us and used injector connectors on most everything, so hook up is easy - just needed to fit the MAT sensor to the plenum. ---- Trigger signal - channel A, 1V per segment: [http://www.vems.hu/files/MembersPage/RichardBarrington/Capri/scope1.jpg http://www.vems.hu/files/MembersPage/RichardBarrington/Capri/scope1-thumbnail.jpg] [http://www.vems.hu/files/MembersPage/RichardBarrington/Capri/scope2.jpg http://www.vems.hu/files/MembersPage/RichardBarrington/Capri/scope2-thumbnail.jpg] ---- Pin mapping: ||'''Function'''||'''VEMS ECU pin'''||'''Wire Colour'''||'''Comments'''|| ||||||||''Power''|| ||Vbatt||EC36-25||Red|| || ||Ground||EC36-26||Black||Direct to battery for lowest noise|| ||Power Ground||EC36-21 EC36-32 EC36-5||Black||Good connections!|| ||||||||''Inputs''|| ||Trigger||EC36-27||White (Shielded)||2.2V spike, so 733 Ohm Rext is needed|| ||TPS||EC36-1||Green|| || ||TPS Vref||EC36-28||Red|| || ||TPS Gnd||EC36-5||Yellow|| || ||Coolant temperature||EC36-14||Blue|| || ||Manifold air temp||EC36-2||Grey|| || ||||||||''Outputs''|| ||Fuel pump relay -ve||EC36-15||Orange||P259_5|| ||Cooling fan relay -ve||EC36-5||Green||P259_0|| ||Injector 1||EC36-7|| || || ||Injector 2||EC36-19|| || || ||Injector 3||EC36-8|| || || ||Injector 4||EC36-20|| || || ||Injector 5||EC36-9|| || || ||Injector 6||EC36-18|| || || ||Injector 7||EC36-6|| || || ||Injector 8||EC36-17|| || || ||Idle stepper A||EC18-4|| || || ||Idle stepper B||EC18-10|| || || ||Idle stepper C||EC18-5|| || || ||Idle stepper D||EC18-11|| || || The new loom is constructed from Automotive-spec Cross-linked Polyethelene wire (-40 to 125 degrees centigrade) and Military-spec Tefzel wire (-65 to 150 degrees centigrade). Fuses and relays are automotive, for easy replacement if and when required. * SAE-J1128 TXL cross-linked polyethelene wire for all except the following: ** MIL-27500 shielded 1 conductor Tefzel for the trigger and WBO2 nernst signals. ** MIL-27500 shielded 3 conductor Tefzel for the serial communication cable. ---- Back to MembersPage/RichardBarrington/TonysCapri Back to MembersPage/RichardBarrington
