UK 03 STi PPP on standard unleaded
Dealer ran it on std whilst in its tenure - how long before ECU remaps to Optimax?
On 1/4 tank Opti to their 3/4 rubbish, car pulls like mad from just under 3 then goes flat and lifeless right through from 5k+
Is this the sensation you would expect from that coctail and how best to get full adv curve without re-set?

You cant reset the new ecu's, they are not quite the same as the older ones.
It shouldnt take long for it to adapt though, id give it a tank full of the good stuff so it knows what its getting

well he's a plonker as well then. Everything points to the fact that the car should be run on 'at least' super-unleaded....
For instance If you put shxite oil in your car and take it back with a blown engine the dealer will try to get out of paying coz of this fact. So why they should they be any different? put the right fuel in and thats that.

So if you nail it with 1/4 tank then the car does push enough fuel through ..........PMSL.....I also hear if you change direct from 4th to 6th you will burn in hell and never be able to beat things in the wet twisties
Note to self, must add under 1/4 tank 75% fuel into the scoobynet book of bullshxit.
Those comments arent aimed at any of the writers by the way they are just more amusing scooby stories where people are being hood winked into thinking they are driving something amazingly special and different.

The car won't feel any difference in terms of pick pick up points on SUL or UL.

never trust your dealer, at the end of the day they just want your cash, they dont want to help.
In the MY02 WRX handbook under what fuel section. It states:- WRX must be run on 95RON or above. STI must be run on 98RON, but 97RON is sufficient if 98 is not available.
Wonder how many dealers have actually read the owners manuals ??

At 1/4 tank my STI suffers from fuel surge. I have also seen this happen on a 97 classic and a 99 wagon. Only had it happen on the track though, not on the road.
It's considered a big enough problem at Knockhill that a paragraph on it is included in the SIDC track day notes.

1) Fuel Surge
2) Heat Soak
3) Warm up/down lap

Best way to re-set the ecu is get a SECS 1004, but the car will feel "flat" for a few miles while it re-learns.
Bob re-mapped mine and set the default figures to maximum...so I do not get this safe learning period...but it's something to be aware of after a re-set.

Back straight, into the uphill right hander hairpin which leads onto the straight.
BAM, everytime at 1\4 tank. Seen this personally on 3 scoobs, many more have commented on it.
SIDC Knockhill TrackDay Notes Extract
d) If you feel a power loss coming out of a tight bend - back off and don't keep it planted. You are probably getting the first signs of fuel surge. If you keep it planted you are risking detonation due to a weak mixture. Return to the pits and refuel. This can happen with half a tank of fuel on board, so don't get fooled into thinking it can’t be happening already, it can!
