Finally UniChip installed

I assume everything with the A\F ratio and air pressure is alright.

+1 of the hot weather or the Air filter isnt clean, ill go clean it today.

Before tunning i had a speed limiter at 195KM/H but now i was able to reach only 200..

I can reach around 170-180KM/H in 3rd gear with no problems, and when i shift it to 4th it reaches around 190KM and the RPM at 4200-4300 and automatilcally shifts to 5th gear:mad: and this happens to all FX's in the arabian gulf as i know.

Thanks for helping

If you can get to 170-180Km/h in 3rd gear, it has to do with your ECU programing. The fact that the transmission is changing gear at 4.5K RPM is not an issue since there is not that much of gear ratio difference between 4th and 5th. But if your RPM cuts off when you reach about 200Km/h it's your Limiter. Remember that what you see on the Gage is an interpretation of your speed and not the actual speed. You could reach 200Km/h and the engine would cut off while the gage showers 195Km/h.

A good Tuner can remove that for you. Usually, FX's in the US are set to 6500 RPM and and well over 120MPH. I'm not sure why they Limit yours to less. Technically, each of the Sectors in the UAE is smaller than some of our Mid-Size Cities. So maybe there is a government thing with the speed limit.

I Used to have a GMC Yukon and it had its limiter set to 95MPH. So it could have to do with the type of vehicle and the road safety as well.

Im sure that he took the speed limiter cuz i reached around 205. And the FX35 Gulf spec can just reach 195.

ill take of my Kinetix SSV and clean the air filter and try again
