Corsa E VXR Stage 3 Mapping

Another Corsa E VXR which was brought to us for mapping and rolling road set up.

This car had already had a Cobra 3″ exhaust system and Airtec intercooler fitted to it by the customer and had previously been mapped. Prior to mapping we benchmarked the car on our rolling road to establish its base power and torque figues which were 227 bhp and 246 lb ft torque.

We then remapped the ecu and carried out a full rolling road set up with datalogging and optimised the software to suit the fitted components.

When finished the car is now producing 245 bhp and 259 lb ft torque with gains right across the rev range compared to the previous remap.

Astra J VXR Development

This summer has seen a substantial increase in tuning demand for the A20NFT engine. This combined with the ECU’s use in the new Corsa E VXR has seen us spending many hours on the dyno looking at data with Stephan getting his teeth firmly into the intricacies, oddities, protocol and hidden depths of the Delco ECU required for example in bigger airflow and turbo applications.

With Stephan visiting us this week we took the opportunity carry out some further testing work on our own  Astra J VXR, already fitted with our Courtenay Sport Racing intercooler and full turbo back 3″ (76mm) twin silenced exhaust system. A lot of time was spent with the car on the rolling road and further updates were made to the software. One of the objectives this week was to further test and calibrate our soon to be released induction kit in order to to fully understand where the best gains are made. To do this a number of filter and air mass housing combinations were tested before finally settling on our preferred design for the A20NFT engine.

Audi TT 2.0 TFSi Rolling Road

This Audi TT was brought to us for rolling road checking after having been fitted with a full exhaust system. The car was previously runing a Stage 1 remap prior to the fitting of the exhaust and had been updated with a new piece of software from a hand-held flash tool and the customer wanted to see the results.

After checking on the rolling road it became evident that further enhancements are required to the software due to the throttle closing at higher rpm.
