Thread: D2 4.6 conversion owners. 4.6 ECU swap & EOI.

So do we have any results? I am keen to see what the difference is.

results?
do you mean actual numbers?

... apparently, some say, it can now (just) outrun a std Td5 ...

... but it's all hearsay until we see some numbers

Haha...I like it. Of course you can only sell that to people who havent driven a TD5 or two...

I know a sequential injected LPG system bases its injection off the fuel injection but will the lpg tune better for a 4.6 than the petrol i jection will?

Otherwise if not does running LPG with a high comp 4.6 work better than petrol - ie all with stock 4.0 ecu and intake etc?

Cheers

LPG will follow the petrol map during closed loop operation as the fuelling is tied to oxygen sensor readings. At WOT (open loop) you can set the LPG map to suit yourself, software permitting.

Thanks mate. That might cure any lean state at large throttle inputs that Mark Adams was speaking of...although if the lean state is also there with large but not wot throttle positions that might not help with towing heavy loads. I can only hope the extra torque of both the 4.6 stroke and the extra torque of LPG means less throttle inputs are required anyway.

Cheers

The 4.6 ECU does not run lean---
The tailpipe was always a clean steel colour with the 4L
its now black

and you can judge yourself by my internal pics how the 4L tune runs,,,,,
