Hi Guys new to the forum and looking for help. I have the older DTUK box with pins and trying to get it setup properly. I have read loads and loads and done quite a bit of searching but still cant find the answers.Even had a quick chat with Andrew online. I have had the box a few weeks and cant seem to find the right settings. I have tried all the maps 1-4 and all the fine settings on each one, each map i started off on 0 then 10% and 20% , There was hardly any difference in each map on 0 and 10%, But each map on 20% i could feel the difference and here is the issue, at 20% on each map the car ran terrible and jerky, on cruise it would seem to keep adjusting itself to hold the speed. Has anyone else had this problem setting these up ? This is what i cant understand after reading all about these tuning boxes? If i had a remap (which i had done previously on a VW T4) they are standard maps for all T4's with the same engine, for instance , i had my T4 2.5 go for 102 bhp to 138 bhp with improved torque. This map would be used for all similar T4s with a 2.5 Why is it that these boxes do not have a standard setting for each vehicle with a similar engine? If for instance someone had used Map 3+2 and had they're car go from 170 to 200 why cant this be used on all the same ones? Also i have read the car needs to learn each map,why would this be the case if it is a program ?
