I have just received my Cobb AP today and I am planing to use Cobb's off the shelf maps for a while.
When I accessed the maps page in Cobb's website, I have found different maps for the different fuel octane rating.
I am from Qatar, and here we have 95 and 97 octane fuel ratings, but Cobb only offer 93 and 91 Octane maps, and there is another rating
which is RON, so in the website it says
91 OCT = 95 RON
93 OCT = 97 RON
When I looked in Wikipedia, it says that in Saudi Arabia they use RON rating, and they have 93 and 95 RON rating (Which should be the same as the rating in Qatar but I am not sure).
So, now I am confused, which fuel rating we have in Qatar??? and which map should I use? is it safe to use a 93 octane map and use 97 octane (or RON, not sure) fuel?
In the near future get an e-tune from one of the vendors which will be better suited for your car than an OTS tune, especially with summer right around the corner
Yes the Gulf countries use RON in measuring the octane rating
The OTS map is universal. However, high intake temperatures that are specific to our region isn't really captured and you may get some knock/detonation in the summer
Moreover, to really get full benefit from the Dodson thermostat you need to adjust the radiator fan operating temp which needs to be done by a tuner
I think I shouldn't use OTS maps or just use it for few days, and I am not planing to get an e-tune until I get new injectors and pumps, which will take sometime.
So is there any way to install LC5/LC6 without installing the ECU tune? I have the stock LC1 on my GT-R and I don't even think about touching the VDC switch until I get the LC updated lol
I would suggest using the Stage 1 map for now. If you are worried about the way it runs please feel free to email the GTR Experts and we can help to get you sorted till you get all the parts installed.
Thank you so much for the help I really appreciate it.
Since stock pumps are enough, I will stick to them, that should save some money hehe.
I will let you know if I am having any issues
Thanks
