Johnnys 1965 Mk1 Cortina 2 door build

[consul315 180]

congratulations, your MK1 looks top! hope you can sort the problems soon and enjoy it totally-good luck!

So far so good, it rained yesterday , so didn't get to drive it , but hopefully more miles today.

Im using a MK2 Cortina tank sender, and a non standard fuel gauge.

I needed an gauge matcher, to match the sender to the gauge and work accurately.

Plus I wanted a low fuel warning.

Well I read the instructions 40 times, watched video's on you tube , and eventually programmed it up, so I see how that works.

The car looks amazing. Well done sir!

[johnny boy 164]

I took the car out to get a few more miles on it , and see if the cutting out had gone.

Well it cut out 15 times in 12 miles, I didn't think I was getting home, but it always cut back in again, and I did get home.

Back on the phone to motorsport electronics, he suggested to cut the 2 wires that went to the TPS, rule out the wiring.

I took it for a test drive and it did it again. So it wasn't that.

I've got to the point , that its unusable, so I'm biting the bullet and buying a new one.

If that works perfect, great , it was the old Nodiz box itself. Or if it does the same fault , I need to look at the trigger/crank sensor in more depth, and the old Nodiz system is working OK and I can put it on another project.

HO HUM

Well I went to fit the new nodiz, and I had to remove the pins from the crank sensor plug, to get it though the bulkhead hole.

I found the wires that I had crimped were very slightly loose, so I re crimped, and then soldered them .

I thought that I would try in again, before I fitted the new one.

Well , it's fixed , I've done 500 miles, and not a problem.

So I can only surmise that the very slight movement between wire and crimped pin, was causing some electric noise that the ECU didn't like.

Well done mate,glad you found it 

[johnny boy 164]

👌

[johnny boy 164]

I've done 600 miles , with no cutting out , so I assume the slightly loose wires to the crank sensor was indeed the  problem.

Motorsport electronics, are a good company to deal with. They have given me a full refund for the new replacement nodiz I bought from them, and never needed to use.

[nascar66 74]

That must have been it then Johnny. You must be pleased. I'll keep Motorsport electronics in mind for any future purchases!

Today I’ve changed from a 13 inch to a 15 inch steering wheel , to see if I like it better 🙄

got to drive it now, see how I like it.

I like the design of the smaller one better, but don’t like the yellow drift marker, and it feels a bit small.

I’ll see how I get on😀

[johnny boy 164]

I've been trying to get rid off a weak condition on the 40 DCOE's  , on light throttle, on the transition from the idle jets.

Fixed it by changing the emulsion tubes from f16 to f7.

I thought I might need some 5 progression hole 40 dcoes, to cure it.

Turns out I don't

Here's  the difference between  F16 and F7 emultion  tubes.😀

Just replaced the weedy U bolt plates with some heavy duty one's 

, 

Also gone to 12mm capri u bolts.

The Old Nodiz started to cut out again, I checked all the wiring , and rewired down to the crank sensor. It kept loosing sync again, getting progressively worse.

So I bought a new one, which is an updated version, works great, and has a smoother advance curve.

Before I fitted the new one, I did manage to get the old one working again. It seems the old one is much more sensitive to the crank sensor gap.
