peter2704 1 Posted December 28, 2018 Report Share Posted December 28, 2018 Ok, supercharging is out at the moment.But been looking at ecu tuning,BOE seem to have a nice tune in the torque 200,makes the car more torquey and more bhp.Anyone done this or had a ecu tune on a n/a 2zz toyota unit?

peter2704 1 Posted December 28, 2018 Author Report Share Posted December 28, 2018 look good ,but i dont want to open the engine yet ,some ecu tunes are quoting upto 25 bhp mid and 10 top which would be just right atm Quote Link to post Share on other sites
pete 1,911 Posted December 29, 2018 Report Share Posted December 29, 2018 Who is quoting that and how much? Quote hindsight: the science that is never wrong Link to post Share on other sites
peter2704 1 Posted December 29, 2018 Author Report Share Posted December 29, 2018 BOE($850) show this on there site and RRR engineering(£1200ish inc ecu), Quote Link to post Share on other sites
Hangar 111 303 Posted December 29, 2018 Report Share Posted December 29, 2018 Peter, RRR were at our workshop today helping with some mapping on the EMU, so I asked about the NA. On an otherwise standard car there is about 15bhp in the mid -range (mainly from playing with cam switch mapping), and very little to had at the top end due to intake limitation. With induction and exhaust, plus probably bigger TB, you can get more at the top. Dave Quote Link to post Share on other sites
peter2704 1 Posted December 29, 2018 Author Report Share Posted December 29, 2018 Cheers Dave for this info, does your 5700 gt do the same or is it different ? I think to gain mid range 15bhp min would be a nice improvement, i am running trd and sports silencer so maybe a little more Quote Link to post Share on other sites

I think to gain mid range 15bhp min would be a nice improvement, i am running trd and sports silencer so maybe a little more We have two flavours of 5700. One is just the cam switch lower, the idea of which is that you stay on the cam between gear changes. Second one has some fuel and ignition adjustments for cars with induction and exhaust manifold changes (as well as cam switch), which should release a little extra power.

peter2704 1 Posted January 2, 2019 Author Report Share Posted January 2, 2019 Seen some of these and they look good ,but I am not sure how good a tune it is or reliable .Last thing I would want is a damaged engine due to some fueling issues.Suppose if someone has had it done and all ok then its a cheap upgrade Quote Link to post Share on other sites
