@ Mihnea , the car has the following problem: (it had even from before the mods) It would hessitate just like cutting fuel above 1.1 to 1.2 bar. Sometimes it would go a bit more , but there was not a certain bar pressure that it occured. Then i found out that my exhaust manifold had a small crack so i decided to change it and you know what happens... why not get a bigger turbo etc. anyway to cut a long story short i have installed know KKK26/27/29 ( i wanted to get it from you but you didn't reply), mtm imo,new exhaust man. rs2 oe, supersprint turbo back (3" downpipe) exhaust, and P-k motorsport chips for kkk26/27/29. Alos i have replaced all the hoses so there are no leaks. The two days ago when we tested the car it goes up to 1.3 or 1.1 bar and then it seems like heating a wall, just like the fuel is cut. We replaced then the fuel filter and checked the fuel pump ( the pump is stable in 3.8bar, according to the 3.8 regulator and goes up to 5 bar at wot). Then tested the car but the problem remained the same. Then we replaced the sparks but the problem remained .
Note that when i suddenly step on it the car turbo does not open nd the car runs like it a non -turbo, and in this case the revs go to the limit without hessitation. When i gradually press the throttle a get boost but then the problem occurs. The guy i do the mods with ( which is an expert in BMW, does m3 and m5 mods and is well knon in greece for his knowlegde in bmw) says its the map sensor.
but i really need your help on this as i am sure you have BTDT.Does what i have described give a hint? He has a ecu reader ( autodiagnos) with audi models but nnt the parametres for the RS2. It recognises the ecu and reads any fault codes. The only fault code we get is the rpm sensors which is normal when the engine is off right? ANyway i had then replaced four months ago.
Could this problem be caused by the air sensor behind the throttle (brown small sensor).
Can you help me on this problem? Also can i pm you cause i m interested in getting the chips from you for the KKK26/27/29, and bigger injectors if they are better for this set up?
Is there anything i can do that would point if the map is responsimle for my problem? We did disconnected the small hose going to the map but the problem remained!
Please reply cause i have nt sleeped for five days now waiting to drive the car an now that it is almost ready i get this ......
