Hi guys


Can any one help with this iv got a l6 ecu and have just installed a lambda sensor can I connect the single out to pin 2 to create a closed loop circuit


Thanks mike

 

It would have to have the software as well, not sure if the hardware on L6 is compatiable even, L8/P8 certainly is. MSD will probably reply soon will a definate answer.

is ist possible to put a L8 ecu on a L6 loom

 

Yes but you need to revert the two wires on the TPS as they read the opposite of each other, I think that is all.

can I still use the same 2wd TPS

 

L6 will not run closed loop.

L8/P8 will run on a 2wd loom, just swap the TPS to a PF09 and revert the two outer wires.

The lambda sensor needs a live, earth, and the signal runs to pin 2.

Even if you use a L8/P8 the software will need to be closed loop enabled for it to work

 

As per what James says, you cant just go adding random extra sensors and hope your ecu will know what to do with them

 

If Im buying a second hand ecu how will i know if it is closed loop enabled

 

you will need to know whats on the chip,

any L8 CAN do closed loop,

P8s should generally always be closed loop as they are adaptive, exceptions to the rule are out there that have had the closed loop disabled for various reasons though.

 

No one is just adding random sensor im using the lambda sensor on a air/fuel ratio gauge at the moment and someone mentioned a close loop so im finding out from the people that know best you lot.

 

Thanks for all the help .

 

what sort of spec are you intending to run?

 

As I said from the start you need the CL software, the hardware needs to be compatible of supporting it, therefore you will need to have a CL chip (I think MSD can do this if you send the chip to them).

You need a L8, it will only be 'CL enabled' if the chip inside is, which brings me nicely onto saying that with a L8 you cannot use your chip you have at the moment although it is possible to convert them.

Tell you the truth im using the 2wd cosworth management on a different non ford engine.
but using throttle body, dizzy, turbo,injectors, inter cooler, loom and ecu. Its a 1.5lt block and only want 250bhp

 

a L6 chip will run in a L8 if you take the baby board out,

This is why we have had arguments with various RS Breakers who sell L8s without the board, because without the board its simply a L6 with a few mods lol.

 

So I guess the 'baby board' gives more memory allowing extra features to be utilized? I know the L8 chips are double the size of the L6.
