Does anyone have the wiring diagram for the VELNAS system ??? Any sort of schematics would be of great help. Thanks.

The Velnas diagrams can only be found in the 84/85 Starion Service Manuals. You will not find any info in 84/85 Conquest manuals.

You can find them for sale on eBay.

Do you have any specific questions?

Yes. I have the VELNAS module , the VELNAS Clock and 1 severed harness (the white plug from the back of the control module and about 4 feet of cable). If anyone might have the pinouts of the clock module & the velnas , I could hardwire my own harness. I know it sounds like a lot of trouble to go through , but I would love to have the velnas hooked up and working.

Velans was designed for U.S. Spec narrowbodies with 83-85 ECU that fired a pair of 550CC injectors alternately.

Without a scanner this is the best that I can do...

Control Unit and Display Unit(Clock) are connected by own harness...
Light Blue/White
Green/Orange
Green/Light Blue
Green/Black
Green/Yellow
Green/Red
yellow/Light Blue
Green/White
Black

Control Unit connected to front harness...
Viewing Connector Plug...

Upper pins
215 - Yellow/White --- Fuse Box #11, ACC
Not Used

Locking Pin

210 - Yellow/Light Blue (thin) --- ECU B-10 (Injector #2 Ground)
212 - Green/White ---- Fuse Box #06, BAT (Taillight????)

Lower pins
216 - Red/Black --- Fuse Box #1, BAT

211 - Red (thick) --- ECU B-1(Battery???, ECU Control Relay???)

214 - Black --- Speed Sensor (Combination Meter) Ground
213 - Yellow/White --- Speed Sensor (Combination Meter) Signal

Would you like for me to research any specific wire?

I appreciate that , I don't have any decent harnesses for the VELNAS box and don't have any harness at all for the clock. The severed harness may not be the specific one for the velnas , as I cut it from a complete JB harness that was given to me with the car , I just found a plug that fitted the velnas and thought that must be the one. The guys from the starion owners club here in OZ are envious that I have a velnas , some of them have never heard of it , and am dying to get it working. The version that I have uses litres instead of gallons , so it must be from a Jap or UK starion.
Is the cable from the Clock to the Velnas a straight through connection ??? (pin for pin) ??? Also , I would have thought that one wire would go to the fuel sender return , for monitoring fuel capacity... I'm not sure , anyway , I really appreciate this information.


***EDIT***

I have managed to fire up the velnas unit on it's own with the pinouts you have supplied me. The only thing now is to figure out which pin goes to which pin on the display unit. I tried going pin for pin , but I have no display. Do you have the wiring (pin no's) for the Control unit to the display ??? I'm almost there. Thanks in advance.

My service manual has the pin-outs for both connectors. At first glance, it appears to be pin per pin. Wish me luck. Here goes...

Control Unit and Display Unit(Clock) are connected its own harness...

Reviewing VELNAS Control Unit Connector info, I found alias cross-reference numbers.

Let's do the Control Unit Front Harness connector one more time...

229 - Red wire, 3rd from right, between Red/Yellow and Brown wires.
same as 56 on Control Harness Diagram
56 - Red same as 35
35 - Red --- ECU Control Relay

same as 260 on bottom row of Rear Harness connector
260 - Yellow/White, 3rd from right, between White/Red and White/Light Blue wires.
41 - Yellow/White ---- on top row of Speed Control Unit 14-pin connector
41 - Yellow/White, 3rd from right, between locking pin and Light Blue/Black wire.
WAIT -- I FOUND ANOTHER PLACE TO TAP!!!!
same as 203 on bottom row of Control Harness connector
203 - Yellow/White, 2nd from right, between Black and Red wires.
90 - Light Gray --- on bottom row of ECU A 18-pin connector
90 - Light Gray, 3rd from right, between Green/Black and Light Blue/Yellow wires.
ECU pin A15 --- Vehicle speed (0 km/h)
WAIT -- I FOUND ANOTHER PLACE TO TAP!!!
same as 203 on top row of Meter 18-pin connector
203 - Yellow/White, 3rd from left, between Green/Light Blue and Green/White wires.
I believe that vehicle speed sensor is located behind speedometer behind dash gauges. This kilometer/hour signal is then sent out to ECU and Speed (Cruise) Control computers. So, there are three places to tap into vehicle speed signal.
---------------------------------
Let me know when you have your VELNAS set-up working.

Full on man , you are a legend .... I now have most of the velnas hooked up. It dims the display when the lights are on , everything is working ... the only problem is the ECU connector is different for your starions. I have to find which pins on the ECU have the speed sensor signal and the Injector signal. Once I find them , I believe I will be the first in australia with a locally made starion fitted with a VELNAS system !!! I cannot express my gratitude to you , you have been a fantastic help to me , and have made this possible. I'll let you know how I go with the last 2 signals as I have to find the pinouts locally , I believe the ECU is totally different here in oz. Many thanks ... stay tuned for more.

The Velnas is a factory option available for 1984/85 Starion Euro-Sport models. There is no mention of Velnas in 85 Conquest service manual.

Mitsubishi was one of the first car manufacturers to offer a trip mileage and time computer with their cars. Other firsts include: steering wheel controls for radio, anti-lock brakes, talking warning system and of course a turbocharged EFI engine.

Hey guys, sorry i havent been around,(or ever posted on trances board) Indy has been informing me of the progress. I have the VELNAS in my 84 ES and also have the manual to go along with the car. The motor is out of it right now but if I can help out in any way let me know. I cant give you any differences between my car and your car but maybe i can trace wires etc if you reach a snag. Good luck with it.

matt

OK Guys , I've got the velnas in , and wired. I have the digital dash , so I worked out the tap for speed signal. I'm going to leave the injector signal wire hooked up to B10 on the E.C.U. at this point. It might be the injector pulse signal from my ECU , we will see. At worst , the fuel consumption part of the VELNAS won't work , then it's just a matter of tapping it directly from the loom under the bonnet (on the throttle body).I'm going to test drive the starion on the weekend ,so stay tuned for more progress. I might write a tutorial on how to fit a velnas if it all works out , and if it may be of use for somebody.

Thanks again for everyone's input on this one.

Just a bit of extra info...

The Velnas uses the injector #2 ground.

Our EFI works something like this...

ECU pin B01 turns on power to injector side of ECU Control Relay.
ECU Control Relay generates 12V power
12V positive filtered thru 6 ohm resistor (to protect injectors)
Constant 12V positive (after 6 ohm resistor) to each injector
ECU pins B09 and B10 grounds/closes 12V negative circuit.

So technically, the ECU does not fire each injector by sending out 12V pulses. Rather the ECU does fire each injector by simply closing the circuit.

Think of it as the same way that overhead interior light, glove box light, and hatch lights are turned on. The light bulbs always have power. The door switches simply ground/close the circuit.

Thanks dude. The velnas probably uses a 10kohm pull-up resistor on the injector pulse input. When the ecu closes the circuit , it pulls 12v to ground on the velnas input , giving the velnas an 'active low'. Most electronic equipment with solenoids (and electric clutches) use this same system. It should all work , I'll find out on the weekend (after I put my power steer box back in , bleed the brakes and change oil/filter , the car has not been driven for years). Thanks again. Very Happy

Just saw this thread. Did you get your VELNAS working? I put one in an '89 several years ago. The only shortcoming is that any computation requiring fuel useage is incorrect due to the diiference in injector firing between the early and late model systems. If you need any help let me know. -Tom

Working fine... Here is e-mail from Powerslave...
--------------------
Hey there , I finally got my velnas working. I had to tap the pulse from the back of the digital dash , as my speedo cable has no pulse generator. The problem was the dash sent out 20 pulses for every rotation of the speedo cable , and the proper pulse generator onlt put out 4 pulses per revolution. So i designed a circuit (using a C4017 I.C.) that divides the pulses by five. Now the distance travelled is EXACTLY same as the odometer. Many thanks for your input on this one , without your help , it would not have worked !!! I'll keep you posted on the progress of my car. The velnas is only the beginning...
