VW Corrado 1.8t 20v rolling road session
This absolutely stunning VW Corrado came to ADE Tuning for an ecu check over/remap,as it had very little power low down. The car installed with a 1.8t 20v engine is running via an Omex ecu. The owner had only owned the car for a couple of months and though it was running rich as he could smell fuel.
With the car strapped to the rolling road we did a power run. This not only allows us to see what power and torque the car is making but it lets us monitor the fuelling.
The Corrado owner was quite surprised to find that his car was actually running lean. Anthony was able to explain this by using the rolling road graph that was displayed on the big screen. Early on in the rev’s there is very little fuel (this would explain the lack of power) causing the leanness 😮
As you can see on the print out the bottom graph shows the fuelling and the black line is the fuelling as the car came. The black line doesn’t even register on the graph. Thank goodness the Corrado owner hadn’t been booting the car around.
With us now knowing where the fuelling needed to be adjusted we set to work.
With the fuelling adjusted we ran the car again (pink line) before letting the owner take the car out for a test drive.
The VW Corrado was now more responsive down the lower end, the lean fuelling had been sorted and we had even managed to get a little more power. The customer was really pleased ;D
This car is one to keep a look out for and WILL most definitely be winning some awards when the owner has finished it.
The owner brought a spec sheet of the work that had been done to the VW Corrado and money has been no object for the previous owner…
