    Lightbulb renault laguna 1.9 dCI, 88 kw, chiptuning project

    Good afternoon all ! I own a renault laguna 2, 1.9 dCI, 88Kw car and i'm in love with it... So basically i'd like to keep it as long as i can but i want to improve it a little so i was thinking to try a remap... The main problem is that my knowledge in chip tuning is not very well so i'd like other participants to give advices or to correct me if i will post something wrong So i will download the .ori fille and i will post it here... step by step i will try to identify the maps and to modify them... good luck !

    I think it's a good idea .. I'm sure someone will give you a hand for your work ... otherwise you can ask for a good job if you want to pay and save time and after studies to make improvements

    Default first task: EGR OFF

    First thing that i did was an easy one: I have disabled the EGR functionality after what i've seen on the engine's air intake... Correct me if i'm wrong but the EGR map is on the adress 6CF14, 15x15. I have linearized all the values to 11100 (EGR closed). Now i will try to identify other maps...

    egr off you if you bring value to the maximum .. you have an error in diagnosis, but it does not matter

    Project reloaded ! I upgraded some hardware - bigger intercooler, decat, stright pipe 60mm exhaust, new turbo - GT2052V and added a new software...but something is wrong......very wrong.I have installed a boost gauge with the range from 0 to 2bar. The problem is that when i press the accelerator pedal to the maximum, the boost value goes to the maximum of the gauge ... over 2 bar !!! With the stock .bin the turbo boost is limited at 1.2bar. Now i want to install a BOSCH 0281002845 3bar MAP sensor but i couldn't find the MAP linearisation map... A little help please
