It runs with a Hondata ECU which has proved itself to be very reliable and more than capable of running this conversion many times.
So why was this one idling at 2500 rpm and almost un-drivable?
With such a popular conversion, it was easy to find information.
This provided us with base maps, tuning specifications and hardware requirements.
The first thing to do was check for fault codes, however there were no codes stored.
So we connected the basic logging equipment to the vehicle and attempted to drive it on the dyno.
The result was extremely poor fuelling and massive overboost.
We now had a problem. The hardware was not compatible with the vehicle.
A change of supercharger pulley diameter was required.
Once this was completed the boost pressure was now within acceptable limits. But the car was still not right.
Looking at the map stored on the ECU, during testing it appeared to have some very poor calibrations.
The answer was a base map from a similar specification car. This is then fine tuned to suit the vehicle. In this case reducing the knock counter at certain load and rpm ranges by trimming the advance curve.
The result was night and day. The car now pulled like a train and recorded a very healthy 188BHP at the wheels or around 240BHP at the flywheel.
