Engine Mapping on the Dyno and on Track
Electronic Fuel Injection (EFI) | Pectel | Motec | Bosch ECUs
Hasselgren has extensive experience mapping performance engines with Pectel (now Cosworth Electronics), Motec and Bosch ECUs as well as some Club-level brands such as Haltech, AEM/Wolf, BigStuff3.
Hasselgren is an official dealer for Pectel (Cosworth) and Motec ECU’s and can supply a full EFI system complete with chassis and engine harnesses, sensors and electronic dash.Â Hasselgren designs and builds custom trigger arrangements, as necessary for the particular engine and ECU.
- naturally aspirated or turbo with electronic boost control
- full sequential or batch fire injection
- individual coil firing or via a legacy distributor
- variable valve timing (VVT)
- electronic throttle (fly-by-wire, FBW)
- knock control
On the dyno, Hasselgren can fine-tune engine mapping with individual cylinder fuel and spark trims using individual cylinder lambda (air-fuel ratio) and EGT’s (exhaust gas temperature).
On track, Hasselgren can optimize engine control for best response and driveability, shift-no-lift (or no-lift-shift), launch control, traction control and pit-lane speed limit control, as appropriate for the particular race car or race series.
