Is the "Performance Chip" for the Rover V8 a Myth?

I to like Biggin would like to find out the real answer about how good chipping and or FMD's are when fitted to a D2 4.0L engine not a D1 3.9.

I can vouch for the unichip on a 3.9 which my D1 has along with headers as was installed by Coopers by the previous owner, this combination makes my good old manual D1 with 33's blow the doors off of my standard tyred auto D2 in excelleration.

So is there a proven chip that improves the power and running of a 4.0L engine?

Cheers,
Terry

Answer is no as the D2/4 L Motronic setup unlike its RV8 ECU predecessors the 14CUX (and to a lessor extent GEMS) leaves little gain to be made in fueling and or timing. That is why no one has seriously bothered investing in making Motronic fueling and or timing chips.

Bugger I must say I didn't really want to hear that!

Seems they do 3.9 and TD5 but not sure about D2.

We are going too trial on the Syntek map conversion units on my Dad's 89 RRC in interim until we install the Wolf ecu.

Getting rid for the MAF and back fire protection valve that are currently fitted should go a long way too help the poor o'l 3.5 breath a bit better!
