Hi this is my first tuned car, please can you rate it.
GT1749V + 0.216 injectors

The car is very fast, but i have some problems:

When the engine temp is under 40 C, at idle is running rough ( I have modified the n108 map but with no succes) iq is 6-7 mg

when is the egine is hot 90C iq 3-4mg, at idle there is no rough, but if i put the clima on,IQ 6-8mg in neutral gear at little speed I feel that the engine is running very rough.

I think that the problem is n108 map or duration or soi.

Please help :angel:

Stock ASV map only with bigger nozzles shouldnt make idle problems, there is something else. Try to write again original map and check.

Have you scanned for fault codes with VCDS? The coolant temperature sensors are a common part to fail in this, I've had to replace it in mine. It will still show temperature on the gauge but it won't send the information to the ECU. They tend to send a set temperature value to the ECU when they go. For example it may be telling your ECU that the coolant temp. is at 10 degrees all the time so when you start the car it will throw in too little and once it's heated up past that it will be overfuelling.
