My car has a japenese performance ecu from Central 20 Racing

 

Now i guess this is set for 100 ron fuel.

 

So do I,

 

Leave it in and continue to use optimax all the time it will be ok

 

As above but also use octane booster

 

Get the Central 20 chip remapped

 

Sell the ecu buy a stock one and get that remapped.

 

Cheers

Aha ..evenin Lymon :cool:

I run about 16psi on my AVCR ;)

most central20 chips I have seen are actually very well designed chips, but a little bit too aggressive for European Fuels.

 

Your whole reply,Lymon is interesting indeed. I was just wondering if you or anyone else has any experience of the Central 20 on the NA engine??

I know we NA people are in a minority here in the UK but we are an interested and inquiring lot really! :)

My limited experience with my car which arrived with this chip seems to bear out the rich fuel ratio bit. But just to help an inquisitive newbie a bit more can you enlighten me a bit more on what "aggressive " means in THIS context and its relationship to Octane rating??

Pleeze????

BTDC....can someone enlighten me as to what that means...something something detination cycle is it?

Some of the early C20 chips were awful. They literally just lifted 1/2 the timing map by 5° and 1/2 by 3°.

Sorry.......RETARD mode....course it does. Cheers.... lol

PMSL Greg .. nice one

what about avtur or avgas ( jet fuel ) will that do. :hyper:

As i work with MOD helicopters

 

i work for the air force.... do not use avtur!! its diesel!! i use it in my 106 diesel some times and i wouldnt use av gas as it has iceing inhibiters in it that will rot your rubbers, plus lots of other nasty stuff.... where do you get the tesco 99 ron stuff (is this a really stupid question? do you actualy get it from tesco?) :rolleyes:

A rough list is compiled here from members ;)

Tesco 99ron coverage

How recent are those prices? Look a little cheap to me.

Yer...

It needs peeps to update again as I have updated Stevenage which rose from 85.9p to 92.9p now.

The thread was started on 13th May...

I will bump it up again and see if anyone supplies any updates ;)

 

Here is the main thread it came from:-

85.9p / Tesco 99ron petrol is here

Cool, cheers. I'm sure in some places now, some places will be fast approaching a pound!!!
