The DC box mentioned in this article can be fitted to Vento as well. please do keep us posted regarding the performance if you plan to get it installed.
Reviving this thread as recently I installed dual channel Dieseltronic in my Pajero Sport to make the Sport Sportier. My impressions over the last 4000 Kms with the unit are shared here in my ownership review.
I spoke to RD guy about 6 month back for My Tata Hexa XT 4x2 and he said the box is available for Hexa but it was Single channel. They are not producing daul channel box for Aria, Safari, Storm and Hexa due to hardware restriction from Tata. So how is it possible to fit dual channel box on Aria ?
