K20 EG Civic on a Hondata K-Pro

Today, we had an EG Civic in for mapping. Following a K20 engine conversion, it appeared to be running on a base map on it’s Hondata K-Pro ecu. We were shocked to see how lean it was running on vtec. We are posting this to warn people that loading base maps to their K-Pro could potentially dangerous for the engine.

Firstly, here’s the car on the Dynapack.

This Image is of the torque (lbft) and power (bhp). These figures are accurate to within +/- 0.1 %. Basically, this is the axle torque (left hand side) and axle power (right hand side) measured at the hubs. The figure for axle torque will be quite high (781.6lbft in this example). It is the ‘true torque’. It is calculated by: the torque produced at the flywheel multiplied by the gear ratio and the final drive ratio. The power figure is the power produced at the axles.

From EG-K20a

Gains: 127.7 lbft and 26.7 bhp (Axle)

This image shows flywheel torque (lbft) and power (bhp). This is the torque (left hand side) and power (right hand side) that is produced at the flywheel. These figures are estimated and are correct to ± 5%.

From EG-K20a

Gains: 29.5 lbft and 30.7 bhp (Flywheel)

The final image shows flywheel torque (lbft) and AFR. The torque produced at the flywheel is displayed on the left hand side of the page. The right hand side of the page shows the air-fuel ratio.

From EG-K20a

Gains: 29.5 lbft (Flywheel)
As you can see in the AFR graph, the engine was running EXTREMELY LEAN. It was just a matter of time before serious damage was done to this engine. Following the map, the car is now running with extra torque and power, and most importantly, it’s running safely.

06 Honda Accord CL-7 Power Run

Today, we had a customer’s CL-7 Honda Accord in for a power run, with very impressive results.

B-Series tuning examples

Honda Civic (B16) – Rally
Here are the results for a Civic rally car that we had in for mapping. The spec was as follows: Omex ecu, Wossner pistons, TDP built head, TDP throttle bodies and cams.

From DynoToday

The first image shows the torque (lbft) on the left hand side of the page, and power (BHP) on the right hand side of the page, measured at the hubs. The torque figure is the ‘true torque’. It is calculated by: the torque produced at the flywheel multiplied by the gear ratio and the final drive ratio. The power figure is the power produced at the axles.

The second image shows flywheel torque (lbft) on the left hand side of the page and flywheel power (BHP) on the right hand side. As the title suggests, this is the torque and power that is produced at the flywheel. These figures are estimated and are correct to ± 5%

Honda Accord SIR-T

Here is the results of a Honda Accord SIR-t with 2.0 liter F20B engine. The cars has the following modification. Skunk 2 Stage 1 pro series cam shafts. Skunk tuner series cam gears. Apex’i Neo Air fuel controller. AEM V 2 short ram intake. Unspecified cat back exhaust.

The cars had the cams and fueling set on the Dynapack for max torque and response rather than high end horse power as the cars is road driven.
