Re: Crank errors at certain rpm
Manual says GAP TOOTH FACTOR The missing teeth are detected by the time difference from the previous tooth. The gap tooth factor determines how much bigger the missing tooth time is before it is recognised as a missing tooth. This can be determined by cranking the engine and using the crankshaft osc...

Re: Crank errors at certain rpm
I'd still be curious to understand what the "filter" setting does and what is the theory behind it. I understand that some of the settings are hard to explain for the ECU manufacturer and they perhaps do not want uneducated "tuners" to mess with settings... but anyway. Which fil...

Re: Crank errors at certain rpm
You are right! Having a scope trace on the field would be really beneficial for diagnostics. Not so many have own dyno where take a trace when something peculiar happens on full load and high revs. I can't plug a scope when I drive on silent industrial area trying to debug the f..king system.

But if it works it works. This is good saying! I'd still be curious to understand what the "filter" setting does and what is the theory behind it. I understand that some of the settings are hard to explain for the ECU manufacturer and they perhaps do not want uneducated "tuners"...

Re: Crank errors at certain rpm
New sensor made no difference.
1.85mm air gap makes engine run flawlessly to current redline 7500rpm. I have no idea why it loves so big cap. Factory gap is about 1mm.

Re: Crank errors at certain rpm
I increased airgap from 1.2 to 1.4mm. During first acceleration test engine turned to rev limiter (7500) withour errors. Then during subsequent trials it hitted crank errors approximately at 7000-7200. Increasing airgap made very small difference, but did not solve the problem. Next time I think I t...

Re: Crank errors at certain rpm
VR type, original Bosch sensor. Wired as per manual, Tyco Raychem stuff. Engine runs perfectly otherwise, but somewhere near 7000 crank errors occur. Stroked BMW M20's are known to have harmonic vibration issues, so I'm primarily expecting that somehow being the rootcause. But how to tackle that? I ...

Crank errors at certain rpm
Hi, I have BMW M20 engine with original sensors, ignition and 60-2. Crank errors occur at 7000rpm and engine hits like rev limiter (which is located some distance above). Crank sensor is original, shielded wire, earthed as per instructions. Even the box (S60) is earthed. Any ideas how to start tackl...

Re: Long log export time
If anyone else struggles with slow data transmission speed I can confirm that the legacy DTASwin works with noticeably higher speed than the new version that is T-series compatible. Map loading speed and specially log download speed is terrible slow with S60 and new DTASwin (when using RS-232 interf...
