Here is the wiring loom now that all the insulation tape has been removed


Here are some pics of some of the sensors. Not exactly sure which is which, so I will need to get a workshop manual. Kalmaker suggest that should be one of the first things to get.

The HP fuel pump off the Camira looks exactly the same as the one I have off a VL Commodore.

The Commodore one looks like it has the reg straight after it though. Not sure what that's about.

Those sensores are water temp, air temp, an EGO sensor and I cant se thru the fingers bit prolly another temp sensor.

The temp sensor are a generic temp sensor used on just about every EFI car apart from Mazdas.
They are NOT polarity sensitive.

The ego can be thrown away. They have a finite life, perhaps 100.000 K's and response becomes sluggish and unpredicdable.

Thanks TSV

So that means the water temp sensor will be replaced with an CHT ??

The air temp sensor goes in the inlet manifold, probably before the TB ??

Yep, looks just like mine. Show me how to do it!

EDIT

I think "Ratty"'s thread has good info on the 'conversion' of coolant temp to CHT

Ooooh goody! Another conversion.

Wiring loom is simple once you have spent some time studying the wiring diagrams and you know which sensor goes with which plug. GM did some strange things with their wiring... I'm still trying to work out why they bothered to connect the fuel pump via the oil pressure switch!? :duh

I went to the local (Southport) public Library and photocopied the wiring diagram from a Gregory's manual. It was a great help. Copy the engine management chapter too - it's useful for checking sensors.

I agree with TSV in regards to the identification of the sensors. Use a 3 or 4 wire heated EGO as the mounting location will probably be too far down the exhaust for a single wire (non-heated) EGO to remain hot enough to be accurate at all times.

In the Camira and the Commodore the Manifold Air Temp (MAT) sensor is mounted very close to the intake ports on the head (ie: after the TB). Some people have reported problems with heat soak with the sensor in this location, which causes the sensor to report higher than actual temps. Most people recommend mounting this sensor further away from the engine, but still after the TB. I mounted this sensor in my brothers conversion in the plenum chamber (where the factory cold start injector normally fits). In this location its 'miles' away from the heat given off by the head, but still in the air that is 'next-in-line' to be drawn into the engine.

For a CHT sensor I used a 'Temp Sender II' from a factory EFI system (type III or IV). It screws into the top of the cylinder head, beside the intake port - check to see if either of your heads has the threaded hole for this sensor as some don't. The Temp Sender II is fairly inexpensive compared to other alternatives. I ended up having to use a resistor in line with the temp sensor to bring the higher temp readings down to what the ECU considers normal - despite what others will try to tell you, doing this has no effect on the cold start. I can supply all the info and research on this subject if you would like to see it.

Looks to me like the loom came out of an auto Camira - you will have to spend some time trying to make sense of/removing the torque converter lock-up wiring ... unless you are planning on fitting an auto too?

I have a few files that cover the Camira wiring loom if you would like them. I could even scan the relevant pages of the wiring diagram that I used... just let me know.

Please keep us up to date... I'm looking forward to this one!

I just realised what the temp sender on the left is in the last photo - its the temp sender for the dash gauge. It's not connected to the EFI system so not of any use here...

Ratty, Astro, the Holdens/Delco use the oil pressure switch as a 'back-up' for the EFI fuel pump. It is normally signalled from the PCM. I don't think it's a 'crash situation' fuel pump cut-off, but it may be...

Thanks Rossco

I think I need to invest in a Gregory's manual :thumb

I am in the throws of decidingwhich manifolds to use. Both are from CB Performance, either the factory-type end castings with the injector bosses in them (neat and tidy, but not an ideal design as far as inlet system volume is concerned); or the IDF-style manifolds with the injector bosses on the inboard side (injector position not as good but able to design a better inlet system with individual runners).

Ragtop (I think) used the factory-style end castings, so I would like to hear more about his experiences if it's back on the road.

Use the individual runner, even if you have to weld some bosses onto some good manifolds.

Bergs may also have some better quality manifolds that wont restrict your engine,
and are a shorter profile to fi in your engine bay.

CB make a runner that has a straighter shot, but I am unsure wether it has nozzle bosses.

Bugpack make a real nice tall IDF manifold too.

While I'm in the process of designing the inlet system and having it made, I am hoping to complete the fuel system. I am planning on having a small surge pot under the rear near the gearbox. What low-pressure fuel pump should I get? Some people have posted opinions here, some are noisy, some are $$$y. Which one should I get?

I picked up a small rotary style low pressure pump from a swap in Toowoomba - it is very quiet.

I have heard that these pumps are a little more expensive than your Carter pumps, but much quieter. My Brothers conversion used a Carter pump - it is noticable when the car is at idle, but once the revs are up you can't hear it.

Does anyone know what kind of pressure a single point injection system runs? Perhaps a pump from the 1.6 Pulsar or 1.8 Camira (JD) may be a better alternative for second hand pumps....

Update .....

I think that rather than buy a surge tank and try and find somewhere to place it I would get the fuel tank modified.

I have taped a plastic container over the outlet and placed the tank back in the car to see if the tank extension would foul on anything. It didn't so I will have the tank modified.







While I was at it I thought I'd try and sort out where the HP fuel pump would go.

Right here on the shelf under the fuel tank. Hole and gromet in the side of the tunnel. Replace the old line with new stuff but in the same location and it will be the return line, back into the fuel tank extension.

(I won't be using that aluminium strap as the bracket either!)

An update

After doing a bit more research I have discovered that:

1. if I use the Delco/Kalmaker pakage I still have to retain a distributor. I want to get rid of the dizzy all together, so that plan won't work.

2. The final cost of the Delco/Kalmaker package is comparable with aftermarket systems.

So I have narrowed it ECU choice down to 2 at this stage:

EMS Stinger
http://www.enginemanagementsystem.com/products.htm

or

Link G3
http://www.linkecu.com/products/engine-management/lemg3-whatdoesitdo

Both of these systems will fire the twin ignition off the crank only, with wasted spark. Therefore doing away with the need for a dizzy (and cam angle sensor).

I have also found a local dyno shop that sells EMS, and has used Link with good results.

I am waiting on some late model FI beetle end castings from OS. When they arrive I can have the intake system finalised.

Yep. They have a better volume for EFI than the CB "modified" end castings. Also Dangerous Dave suggested the CB ones could be restrictive.

Remember, this is going onto a daily driver (not a racer) with a designed red-line of 5500. That being said, the end of the runners (injector end) will probably still need a tidy up.

I am so watching this thread!

I have a dead camira up the road that I am going to lift my carton of beer offer on 😂

I have the t1 engine, my workbench is built and ready for paint and hardwood top.

What $$ did you end up paying for the mexi manifolds etc in freight? I have been looking for them
from a mexi wrecker but communication has lapsed...

Planning bigger barrels, fi, air con and alternator..

Astro, make sure you place a strainer in between the tank and the pump. This is not a filter as they are too restrictive to place there. Make sure it is a strainer. Then a filter after the pump. The pumps dont actually suck any fuel and need to be gravity fed. It is a misconception that they suck fuel. T54 😉

I may not have made myself clear,
I was refering to the restriction of ANY "end casting" and single butterfly,
flowing less air than a dual carb manifold.

I have no experience with the CB end castings, but know that a centre mounted single butterfly will make less power
than two separate throttle bodies on IDF or IDA style manifolds.
(on a turbo application, this may not be the case)

But as you said it is your daily driver, so this loss of power will not concern you.

I have looked into the CFM capacity of the Camira TB, and it flows more air than the 1915 can consume at 5500.
