BMW 6cyl firmware upgrade from 1.0.46. to 1.1.18

note: It might be a good idea to avoid accented characters in page titles

Ignition output channels. PLEASE SORT TO FIRING SEQUENCE, and WRITE CYLINDER NUMBER TO EACH!

Please verify that the chosen channels are power-outputs. Measure (with ignition ON, but engine NOT running) that voltage between +12V and the ign outputs is 0 (a logiclevel output pulls down to 0V when inactive, so that would measure 12V !)

1.0.46 firmware works great with

1.1.18 firmware plan:

Engine does not start, shows wheel-error.

Trigger hints:


Analog input

NOS thoughts

BMW M20 B25 (6cyl, appr 2.5L) modified bore ( 81 mm ) now competing in 200m and 400m dragrace (earlier it was a rally car with restriction before a smaller turbo)

Would NOS be useful to kick in for a short time after launch ?

During launch, engine RPM drops so low that turbo doesn't work well for a short time.

When the turbo spools up and boosts, NOS could be switched off.

Would this be useful ?

Not sure why he does not use higher launch RPM (maybe he fears the clutch would explode?)

´

Be careful with nitrous oxide if the engine bogs down on launch, even a small nitrous shot will give a very large boost in torque at a low rpm. The cylinder pressures could get very high and detonation can easlily occur. -Jörgen


Choose output for N2O - see GenBoard/Manual/DigitalOut/Table

The guy who installed did not document the wiring.

We reverse engineer from the mcd/mct dump.

This is a 6 cyl engine. The 0F in h[0] looks like it came from a 4 cyl engine. (Roland has a strong 1.8L 4 cyl BMW turbo)

h[0]=0F 00 00 00 20 80 10 00
