EURO+DRIVE testing data for the EURO+DRIVE & EURO+DRIVE CLONE ECU platforms for the Fiat 124 Spider and 124 Abarth. Dyno information is below.
With the addition of our new 124 ABARTH (MT) and 2WD/AWD HLS Dyno in the shop, we decided to start from the beginning and obtain testing information for all tuning phases from the new dyno setup, all on the same vehicle.
An HLS dyno (hydraulically linked system) controls both the front and rear rollers via a complex fluid pumping system using hydraulic oil, which allows for both sets of rollers to be synced with no margin of error. This allows for any car (either 2WD or AWD) to be tested exactly as it would drive on the road (less the air pressure and cooling effect at the front of the car), with no dash lights or interference from the traction control and stability control systems. This also matches the speeds of the front and rear wheels.
This technology also allows for complete control of testing at various rpm points, load stages, and throttle input. The vehicle can be held at any stage in the powerband, under any of the above conditions for as long as we allow, all while monitoring data and diagnostic information.
The goal was to use the same car, on the same dyno to re-test all of our tuning work thus far, and make any fine tuning adjustments as needed to the existing maps.

MAP INFO (results shown below):
- STOCK map: 91 Octane gas, no other modifications
- PHASE 1 map: 91 Octane gas, no other modifications
- PHASE 2 map: (same as above), FMIC, V4 Intake
- PHASE 3 map: (same as above) 91 octane gas, EC Upgraded Turbo
- PHASE 4 map (in development): This map is designed for those that would like to run an upgraded turbo, but will not be utilizing only pump gas, and instead a properly adjusted water/meth system or E85 with larger injectors. Our testing/mapping will feature a full Supersprint exhaust system with a catless downpipe, and full water/meth system control.
All runs (stock - P3) were tested using standard 91 octane pump gasoline and in linked/locked 4-roller configurations.
Our 124 Abarth also has the entire stock exhaust still intact on these runs.
All runs listed in WHP as well as BHP (engine horsepower). The loading feature on our HLS system allows for measurement of gear ratio on each run, and measured power dissipation during pre-run procedures, as well as post run coast down measurements. This data allows the dyno software to interpolate a parasitic loss from WHP, and graph estimated engine horsepower. The BHP data is based on this dissipation measurement for each of the raw WHP run data.
