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)||See notes below|| ||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. '''Trigger notes''' Check that R30 is removed, and that JP7 is jumpered. Existing 10K R55 should be OK, but could reduce to 1K if necessary. C30 could go up to 100nF if coil signal is too noisy (it shouldn't be though). ---- Back to MembersPage/RichardBarrington/TonysCapri Back to MembersPage/RichardBarrington
