I checked the chip I used and confirmed it modifies the signal from the ECU.
The link is below (don't mean do give any trouble, just in case you want to check).
About the chip installed, I just plugged in the common rail fuel pressor sensor. The other plug was connected as bypass in the original harness. To remove I just unplugged, nothing else.
At the dealer they told me they checked the signal in the harness sensor to ECU and it was ok. I believe they have not checked the vacumm boost leak yet.
About the smoke exhausts, when the car is in the idle march rpm it does not make smoke. The smoke only appears when the accelerator is used to put power in the car
About the code error, the dealer plugged the computer to my car and onlu one code error problem appeared. It was with MAF only nothing else.
Thanks any help
