Just made the change from up rev to ecuteck .For any one interested .
It was on my 2015 e70z nismo . Horsham Developments carried out all the work and did a top job as always.
So i already had a exstreme clutch kit,slave cilender and light weight fly fitted so i went ahead and took advantage of the goodies on offer launch control ,flat foot shifting and tuned traction control. All of which have put a huge smile on my face. The launch control gives you adjustable launching rpm using the cruise controle toggle .The flat foot shifting means you can keep the throttel wide open and let the electronics do the work during gear shifts (it sounds ****ing awesome 💪) and the traction control has e settings either nissans on or off rubbish . Fully off or the enhanced traction control setting which allowes for progressive slides but most impressive is it really controls the launch without spinning up the rear like mad also from 1st gear to 2nd stopps the wheel spin and just feeds the power smoothly .
It didnt make anymore power at peak just remained at 355bhp at the crank. I installed a ported intake manifold befor the tune which also didnt net any top end bhp but did gain around 5bhp mid range.
All in all money well spend and i would strongly recommend getting it done .!
