Bootmod3 non-ZCP / ZCP (Comp) / CS / BM3-CS / BM3 STG1 91OCT dyno results

Stupid question - the original dyno graphs on page 1, are they wheel hp or converted back to flywheel hp?

All maps were run 3 times to let adaptions kick in. We did first pull, gave it 5-6 minutes, then 2 runs where power was more or less identical, but differing from first pull.

The first picture shows all the runs we had with appropriate names on them.

Test car is an M3 F80 DCT EU spec. Stock car with K&N filters.

The following maps were tested:

Non ZCP 431HP
ZCP 450HP
CS 460HP
BM3 CS (slightly overpowered)
Bootmod3 OTS Stage 1 91OCT

All runs were done in Engine on sport plus, Manual mode 5th gear and on Shell V-Power 100RON(93OCT), but it appears on the logs that the fuel is not that great

Made a short video of how to set the car in dynomode prior to doing the pulls, my video editting skills were put to the test

Logs shown are 3rd pull so adaptions were settled more or less:

Those figures look like WHP to me.

Halim uses a wheel roller dyno so it's WHP.

Only the "engine stand" dynos should output at-the-crank HP/TQ.

Any CHP to WHP conversion is usually way off and reads too high. I think our Sport Displays show crank HP badly converted to look good (and never matched my dyno runs).

I've read every page in this amazing thread, lots and lots of useful information! Perfect for a noob like myself.
