2012 sport JK manual trans (export model)
we do need some assistance from you guys to to resolve this issue at the earliest

I'm loving this tuner..I feel a lot of torque, love the throttle boost. Gear shifts feel smoother..Just an all around improvement.

Do u have auto or manual trans?

Emirates81, do you have any idea what is the best tune; 93 or 91 ? Im from Oman
I install 91oct today into my JK auto but i didnt feel that much of change except little more response. The 0-60 is around 8.18 - 8.08sec with or without tune, and the gear shifting not that notable
I correct the speed meter to match 18" rim and now are matching GPS speed (was 7km different)

My first experience was with G8 and the tune was very notable and you can feel the different immediately
I know there is big different between v6 and v8 but at lest you can feel somthing after tune your car im little disappointed.

Till now i cant drive it cause there is no response at all

I think the problem is that the tune is made for auto trans only.

Anyway i have sent my factory tune to mike hope he will find what is wrong.

Try 93 cause we use 95/98 ron type

hi emirates81 & last69

this is for your information guys

A little help for those of you outside North America, who get 91, 95, and 98 octane from your pumps.

Octane is rated in multiple ways, RON, MON, AKI. Lets explain them.

RON - Research Octane Number. RON is determined by running the fuel in a test engine with a variable compression ratio under controlled conditions, and comparing the results with those for mixtures of iso-octane (RON & MON 100 by definition) and n-heptane (RON & MON 0 by definition). This is how they measure gas in most of the world. You'll normally find 91, 95 and 98 octane.

MON - Motor Octane Number. MON is also known as aviation lean octane. MON is a better measure of how the fuel behaves when under load, as it is determined at 900 rpm engine speed, instead of the 600 rpm for RON. MON testing uses a similar test engine to that used in RON testing, but with a preheated fuel mixture, higher engine speed, and variable ignition timing to further stress the fuel's knock resistance. Depending on the composition of the fuel, the MON of a modern gasoline will be about 8 to 10 points lower than the RON, however there is no direct link between RON and MON. Normally, fuel specifications require both a minimum RON and a minimum MON.

In the US, we add both RON and MON together and divide by 2 (RON+MON/2)to get our pump octane (87, 89, 91, 93, etc). This is the octane rating that the DiabloSport tunes are based on. Its also known as the AKI, or Anti Knock Index. Because of the 8-10 point difference between RON and MON, the octane rating in the US and Canada is 4-5 points lower then the rest of the world, for the exact same fuel.

RdON- Observed Road Octane Number. Derived from testing gasolines in real world multi-cylinder engines, normally at wide open throttle. It was developed in the 1920s and is still reliable today. The original testing was done in cars on the road but as technology developed the testing was moved to chassis dynamometers with environmental controls to improve consistency. Its rarely used in the automotive world, and most people don't even know it exists.

I hope this clears up the confusion for those of you not in the US/Canada. Use the 91 tune if you use 95 RON octane fuel. Use the 93 tune if you use 98 RON octane fuel.

our 95 = US 91
our 98 = US 93

Thanks Bu Hamdan for the info.

Still waiting for mike to resolve the issue. Once done I will let you know.

Thanks bin_hamdan for your great info, but the problem is we didn't have those number in our gas station, its mention 3 type only (Super, Regular and Diesel) so we cannot know the number of what oct we have.

Just ask the gas station manager how many octane is super or regular.

By the way I don't believe in 0 to 60 timing.

What I do is try with other wrangler before and after tune (legally sort of)

[Emirates81]

Thanks to Mike for solving the issue .

[bin_hamdan]

still facing the same issue

which tune, and what octane fuel?

Thanks
