So what does the $12P code have that is unique/better?

The 3 tooth trigger wont be suitable for running multiple coils. Even with the programmable module it needs to have more pulses. There are two reasons for this, firstly on multiple coil setups there needs to be a way to ID cyl #1, a cam sensor or extra tooth can be used for that. But the other issu...

But I'd like to see you try and we can help, and if you can do it and document it there will be a lot of V12 jag owners who will thank you for it. :) I am on a pretty tight budget and MS would run between $1-2K , (spent way too much on the body) So I will give it a go, I am an electronics tech so I...

That will work for 12 cylinders of ignition. If an 808 ecu would be a better option is worth considering and you should be aware that the ecu does not natively suport 12 cylinders for fuelling so you'll probably need to treat it like a 6. We can help but it will be harder than a 4 6 or 8, and resul...

From what I understand this module will allow me to run the V12 with 1 say VY ECU in batch fire with wasted spark. Is this CORRECT. Do you know what type of trigger config the jag has with the factory ECU? Crank or dizzy? The pattern (ie missing tooth, extra tooth, ref+sync..)? if its a hall or rel...

This looks like it might be exactly what I need. Firstly I am restoring a Jaguar XJS V12 and will be rebuilding a spare engine I have for better performance. From what I understand this module will allow me to run the V12 with 1 say VY ECU in batch fire with wasted spark. Is this CORRECT. Is it avai...

Megasquirt have an option I am planning on running about $300 not too bad

Thanks for the help guys. This might see me able to use dual VY V6 ECU's on V12 Jag

SC V6 is not a flash based PCM, they still use a memcal. You can buy a spare PCM still but will need to have it linked to the BCM or disable VATS on the memcal. On SC models its easier to just keep your current memcal and PCM, and just use a 2nd memcal to play with changes. You need a programmer an...

Hi guys, I'm new here just found it googling, Anyway I have a question regarding the compatibility of PCM's. I have a VX Calais SCV6 and want to start delving into tuning the PCM. I will purchase a spare, so can I buy any auto V6 VX/VY PCM to flash my current setup into for testing, or does the SC E...
