This as been probably been asked a thousand times but what petrol whould be best for a 96 wrx import only ever used standard 95 octane but was wondering if 97 would be better.

Thanks robbo

 

You really should not be using 95 octane fuel in a import!

 

tesco99 ron or v power you will have early detonation off engine using 95

 

97 + octane booster until a change of ecu and remap.

 

chance would be a fine thing in northern Ireland mate.

 

Thanks for the replys what octane booster do you reccommend and where the best place to get it.

cheers

 

Anyone know a good remapper in the manchester area, the car was imported 3years ago don't know much about the history of the car is thier any way of tellin if its been remapped in the past ????.
no more 95 for me till i know about the remap.

 

97 is perfectly fine for early wrxs.
Check the ecu,passenger footwell underneath the carpet and a there should be a kickplate have a look it should say Z4 (if it's a saloon) open it up to see if there is an extra chipset (bottom rhs of this picture) if there is it will most probably have been fiddled with.




Octane booster is a waste of money unless the car has been chipped/remapped

 

try

try jolly green monster simon is brill at mapping

 

I'll have a look in the morning at the ecu, mines a WRX Wagon if that makes a differance with the ecu ??
Thanks for all the replys.

yes your ecu and turbo will be different to a saloon BUT will still be fine running on 97 ron petrol (BP ultimate doesn't seem to agree with imprezas though)

 

I know my turbo is a TD04 I have a TD05 ready to fit when l can find a good mapper in manchester area.

Cheers

 

My local shell garage is being refurbished so i got stuck with a tankfull of BP Ultimate 97 , as myblackwrx has already said my car ran noticably badly / roughly , its a my96 jdm sti wagon . Now back on the good stuff from shell and an ecu reset .

 

i got mine done by andrew carr (hes from preston but mapped mine in irlam) yesterday and i absolutely love it the car now pulls like a train. he charges £300 for the first map and about £120 for tweaks

 

Hi all do you have a number for andrew carr so l can give him a buzz.

My ecu says 3B on it l do have a spare ecu that say's Z4 on it this came from the same year 96 classic saloon will it work on my WRX wagon both are 4 connector units.

Cheers

 

it will work but it's mapped for the TD05.

 

What will it do to the TD04 turbo if l fit the ecu first ????

Cheers
