I took my car to FC performance this morning with a few niggly issues such as poor off boost performance and lumpy idling. I arrived at about 9am and Leighton explained the approach he would take. I was happy to leave the car with him for the day so I left him to it and received regular updates until about 5pm when the work was done.
Leighton explained that the 3.8bar FPR was causing more of a hindrance than a help because it was actually causing the ECU to lean off the WOT map
. Anyway he sorted this out and mapped the fuelling for approximately half way between my low and hi boost settings
Driving home I was instantly aware of how much quieter and more refined the engine felt, like going from 3 year old mineral oil to new fully synthetic
. Also on the motorway journey home the oil temp would not even reach 40 degrees whereas before it used to sit one or two notches above the 40 mark (although it was a chilly night tonight). I'm not sure if this is just a coincidence and the sensor is faulty or if it is now running much cooler
.
I'm most pleased with the off boost performance which is now so much better, it feels like it spools up 500rpm earlier
. This was my main request and I'm chuffed with the outcome.
It also feels considerably quicker, especially on the lower setting so overall I'm really pleased with the service and the outcome - I would recommend FC Performance to anybody who has modified their coupe. Leighton will post before and after graphs when he gets time - poor fella has to change his suspension tonight after a day's mapping
