Hi,
I have a problem with a friend's peugeot 306 1.8 16V 1998 with Sagem SL96-2 ecu.
We put the intake manifold and injectors from the 2.0i and a performance air filter, now the car needs more fuel, it runs fine up to 1/4 of the throttle but more than that the car loses power because it has too much air coming in and less fuel.

I have Kess V2 and MPPS V18 and tried to do an OBD remap (this car already has obd plug) but I couldn´t read it.

Is there a possibility to read this ecu to remap it with the interface I've got?

Thanks,
