kennny1000 0 Posted August 4, 2012 Share Posted August 4, 2012 Looking for some advice here. I have a 2005 2.0 D4D Avensis and would like to get it to accelerate a bit quicker mainly for overtaking on the A1 going up to Scotland when trapped behind a row of trucks. It has 130,000 miles on the clock and I never had any problems it however still returns great mpg. It gets serviced every 10,000 miles by myself and it has never missed a beat. Instead of spending a fortune on a new car to get better acceleration I am thinking of spending a few hundred to it remapped. Now is this advisiable and can anyone make any recommendations Quote Link to post Share on other sites
Heidfirst 1,012 Posted August 5, 2012 Share Posted August 5, 2012 you can't get it remapped as no one has cracked the Denso ECU.However, you can add a piggyback box - the ones from Parts-King on here & Tunit seem well regarded.bear in mind that this is notifiable to your ins. company & may affect your premiums.

Phil24RN 6 Posted August 5, 2012 Share Posted August 5, 2012 I have the 2.0L 09 avensis estate and I felt the same, so I bought a tuning box from diesel tuning online for £250 and it's made a hell of a difference!!! Better mpg and a lot of power aswell. It plugs directly into the fuel rail, so is easy to fit. Definately worth looking into if you do a lot of driving.Phil Quote Link to post Share on other sites
revband 43 Posted August 5, 2012 Share Posted August 5, 2012 If you would like to send me a PM, I have one of Parts King's units for this car which I was very sad to learn it would't fit a my 2011 model.The difference is fantastic more pull from very low revs all the way through plus better fuel economy if you drive normally.
