Optimax VS V-Power - remap question
Morning all, I have a question about my remap.
I got a new engine slapped in about 6 months ago and had an EcuTEK remap based on the 99ron Optimax fuel. Would there be any benefit to now get a remap on the V-Power fuel as I’ve been told it’s a higher ron fuel? My car is a MY03 WRX with an STI engine running 330 BHP. Cheers, MikeyB |
i think a few ppl are getting poor fuel consumption on v-power due to not being remapped, i know i am, i think im getting about 200miles to a full tank.
|
I'm getting between 180 and 190 per tank every time.
I've got the K&N Typhoon (wing) induction kit sat in my loft, I think I'll stick that on too and go for a remap. Does anyone know what RON (officially) Shell has given V-Power? |
Optimax was 98 RON, V-Power is 99

Wait until you fit another mod that would require it and then get the remap done. Otherwise the cost would outway the gains I'd have thought. :thumb: |
Here's a question about after mapping on V-Power. Is it safe to put a 10er normal super unleaded in if caught short between shell stations. Obviously not driving on big boost. Newage ECU, which I believe should cope with adjusting to different fuel types without reset
Cheers. |
If you have already had a remap, can the ECU still adjust to different grades of fuel?? as far as I am aware, it can't??
I.E, if you map for Optimax (V-Power) and then put 95 ron fuel into the car, the ecu will NOT adjust thus you losing performance, is this correct? |
It's not the loosing performance I'd be bothered about, it's the DET and associated problems.
The newage ECU will still retard itself after a remap as its knock sensor still works, it's just how far, and whether it can adjust enough to cope with a bit of super unleaded every now and then. |
I had my STI5 ECUTEK remapped on V Power. It's by no means heavily modded, just the usual exhaust & filter type thing, but mpg is not great, so I dont think the economy from V Power is as good as it seemed to be from Optimax.
If you have a car mapped for Optimax, like it's been said, I wouldnt have thought a remap would be worth-while for V Power unless additional modifications are made.... As for using lower grade fuel in the absence of a suitable Shell stn, I alway carry a couple of bottles of octain boost, just to add to normal super in such eventualities - & then head for the nearest Shell garage whilst keeping off boost. It's only happened once or twice, but you can get caught out.... :) |
Please... Unless you're running horrendous levels of boost a tenner's worth of SUL is not going to kill the car. For every person on here who knows Scoobs inside out and wouldn't dream of polluting their tank of V-Power there are 50 actual owners out there putting in whatever ****e from whatever garage they happen to be passing without breaking down 25 yards up the road.

my car was mapped on optimax and when i brought the car there wasnt a shell station about so i put £10 worth of unleaded in, didnt use the boost all the way home and it ran fine
|
Ok, Ta. Sensible question to ask I thought as I'm not a mapper and don't fully appreciate the fuel tolerances that the ecu can deal with :)
In fact has there been any cases of someone killing a Newage with Det, when the MAF is working normally, or are the ECU's now clever enough retard sufficiently or limit boost in a limp mode to protect it (01 >) ? |
Had my 02 STI recently mapped by Andy Forrest on V-Power and he said it's not a problem to revert to 97 if your caught short but it will reduce the power while doing so. He said to keep away from 95 now i'm mapped to V-Power though.
