Re: V12 ECU

Not one but 2 problems on the fans. Bad contact into the connector from the Otter switch and a grilled ground cable connected to the relay. Yesterday afternoon I ve done ~1km on the road. All sounds good. A few meters on the 5th. https://youtu.be/_kn9hV8CU5I https://youtu.be/oL3UIERpyRY Next step is...

Re: V12 ECU

Philip
With the fact that nothing seems to happen with the vacuum applied manally, I'm looking now for a new Marelli ignition ECU.
Hope to find one soon.

Re: V12 ECU

On your question : "One last question: When the engine runs, can you hear the injectors clicking? (mechanic's stethoscope or long screwdriver or wooden dowl)" Yes, I've tried with a wooden dowl and I've been able to hear the several clicks done on each injectors. As I do have a second set of 12 inje...

Re: V12 ECU

Hi, I've changed the plugs and set the pot @0.36V. Not easy for sure. It looks like it has less fumes. But the problem is that the car is not far enough reassembled to go on the road and run enough @higher rpm. :hammerdrill: I 'll set this topic aside for now. I'll come back later on and after been ...

Re: V12 ECU

Hi, Ive measured the pot as you did. Between G and Y I find 4,47K, Y and R starts at 0,65K until 3k. Not the same result. As I understand that the Red is the signal, Mine is high compare to yours. In other words at idle I've already a signal from higher rev. I'll reduce the value by setting up anoth...

Re: V12 ECU

On the doc from R Bywater to get an XJS engine used in the E type he indicates that this switch brings 15% more @ full throttle. If mine gives not a clear 0 , it may bring these 15% more, dont you think so ?

Re: V12 ECU

I' m talking about this "valve", Depending of the Jaguar litterature, it is call switch or valve: https://i.postimg.cc/Kv41K3Sr/Capture-vaccum-valve.jpg because engine off the resistance is not 0 but ~20 Ohm. And it opens with a vaccum. If the engine needs 0 ohm, my probleme could be there, dont you...

Re: V12 ECU

I though to have some test to do and finally find something.... For now on, I'm stuck with the same result. Philip, you were right, plugs dead very quickly when there is too much fuel. I've replaced the vaccum pipe, same result.... I had a set of injectors plugged on another rail. I've tried it, sam...

Re: V12 ECU

Hi Philip Thank you for your kind reaction. About your remarks, 1) I confirm that the small hose is connected on both side. However I’m wondering if I’ve not bent it during the re routing from the wiring. I’ll check this. 2) I’ll verify the one dedicated to the EFI. I do have fit a new one at the re...

Re: V12 ECU

Yesterday was a first running test with my EFI E Type under restauration:

The brakes, the gear box on first and the reverse gear, the power steering, all seem to be good! :bouncyyellow:
I now have to solve the too far richness of the engine. :scratchheadyellow:

Re: Series 3 Brake Servo Replacement⅚

Because you are going to change nearly all the brake fluid, Ask your guy to use silicon brake fluid. No more moisture in the circuit and no danger for your painting.

Re: Help for the wiring loom

Dear Michel, While you have all of that apart, cut yourself an access hole and make a cover plate at the bottom front right of the transmission tunnel cover, so you have good access to the clutch slave cylinder and can easily bleed the clutch without dismantling half of the car or having to crawl u...
