hi guys
i have seen a land rover specialist who proposes to remap the FF ( 4.4 v8 petrol jaguar engine) for it can run bioethanol at 100%.
Have you heard anything about such modifiaction/remaping ?
any advice about that ?
thanks a lot Current: L322 TDV8 4.4

Doesn't bioethanol have reduced lubrication properties compared standard pump petrol ?
If it does, using 100% bioethanol could have a very bad effect on wear of valve stems / valve guides perhaps. Paul,

hi pawl
yes perhaps etahnol could have a bad effect on certain parts..
but perhaps not, that is the purpose of my post, tryiing to get some experience feed back if some guys have some. Current: L322 TDV8 4.4

I believe ethanol destroys rubber fuel hoses.

Sorry what is the purpose of this? If it’s to reduce running costs wouldn’t lpg make more sense as tried and tested?
If it’s performance with the gains youd get a remap intake and exhaust would probably do a better job and not mess the engine up Current stable:

I think it may be more to do what fuel is available in Vogue16s location ? Paul,

Is lpg not so cheap? Current stable:

yes perhaps, but the cost for installing LPG is not the same.. Current: L322 TDV8 4.4

Ahh ok fair enough - well ultimately it’s up to you but lpg is pretty much tried and tested - bioethanol may be great but no one on head can really tell you I doubt... you may be pioneering something here! Current stable:

yes it seems no one tried ..
but i will not pioneer too far..
even if the running cost is very interesting there is too much dark areas.
i am not sure the jag engine is rerady to accept it, i can not find any information, i tried the jaguar forums and it is the same..
so i think i will just keep my ff stock . Current: L322 TDV8 4.4

Lpg is still cheaper no? Pretty much tried and tested? Current stable:

hi guys
some news about that, for those interested
apparently a company specialised in remaping here, remaped a L322 5.0L supercharged with success,and also a 4.4 with the bmw engine.
The cost is quite reasonable 495€..
it is a flexfuel remaping of the engine management, so you can use bioethanol or petrol as you want.
they guarantee to take your car back to origin if you want for free..
i am tempted to try..

If it's not your daily car I wouldn't bother to be honest.

If you do go ahead with it though, be interested to see and hear how you get on.

good luck Alex

Bio-ethanol is hygroscopic (it absorbs water) so using the vehicle only occasionally may well result is corrosion in the system
Bio-ethanol has only 70% of the efficiency of petrol so more needs to be burnt to achieve the same performance
Bio-ethanol does not have the lubricity of petrol and burns much hotter; this may cause damage to the fuel system/injectors and spark plugs
Pure bio-ethanol is very difficult to start in cold weather. Commercially available fuel containing bio-ethanol has a ratio of 15:85 petrol:bio-ethanol for this reason
Bio-ethanol is pure alcohol and may well attack plastic or rubber connectors in the fuel system
