Right, I'm gonna reset the ECU tomorrow...just to double check...do I reset the ECU first and then fill it up with Optimax or is it the other way round

Second and most importantly what happends if and when I mix petrol with Optimax and Unleaded Looking at it obviously, theres not always Shell station everywhere Any damage/problems if I do that, etc

And any other good tips/points :winky:

Thanks in advance :D

You could always keep a little jerry can of optimax in your boot... and get a list a Shell stations and keep it in the glove box....or even carry a little bottle of octane boost ( for emergencies )

There is no problem mixing Optimax with unleaded, you just won't get the full benefit.

I would wait until the tank is empty, fill up with optimax, use half the tank and then reset the ECU. You need to car to be using the optimax before you reset the ECU.

Excellent :winky:

Another thing, where are the 20amp EFI and 15amp ECTS fuses located Under the bonnet or the driver or passenger footwell Or even somewhere else that I would have never known :P

[ColinBarber]

Under the bonnet near the suspension strut

Woppee, done the ECU thingy yesterday, used half a tank and then resetted the ECU. Question... About to go South Wales tonight (from London) and obviosuly will need more petrol to complete the journey. Anyway if I tank up now (optimax) bearing in mind I still have half a tank of it left, will it effect it in anyway's Or do I need to use all the remaining fuel and then tank up to get the maximum benefit ;)

[ColinBarber]

Just fill it up with optimax now.

Reset mine at the weekend, accidentally drained the Battery completely.

You're da man B) :winky:

Sanj, it would be interesting to see what your results are, I have been using optimax since I got my car last year, however I have never got much over 30mpg. A while ago I was doing a lot of motorway commuting and even then on average, bearing in mind I would still do a fair amount of driving round town too, I would get around 27mpg most of the time. Recently I have been doing mainly driving round town, getting down to 24mpg some times. However today I reset the ECU, and in the new year will be going back to motorway commuting everyday, so like yourself I am hoping to see some improvements!

Cheers

i found that your fuel consumption will go up for at least 1 tank of fuel after resetting the ECU

but after finishing the first or second tank, then u will feel the fuel consumption slowly go down

so thats why you shouldn't reset the ECU too often....

because the benifit only kick in after a few tank of high fuel consumption driving

[Mattj]

so its gonna get worse before it gets better

anyhow after resetting it, I used the removing fuse method, the clock and trip counters reset, I thought this should only happen if you disconnected the Battery instead, could I have removed the wrong fuses??

[ColinBarber]

Sounds like you pulled the wrong fuse if the clock was reset.

[Mr-Lex]

Results are in.... got 310 miles using optimax and by resetting ECU. Half the tank was motorway (above normal speed ) and the rest town driving. It is a great improvement from the results I got previously. This is my first tank full using optimax by resetting the ECU. I will give it further "tests" before I say I am benefiting from this ;) But gotta say, felt some little more power and obviously got more miles out of it!!!! :D
