Tooth Length Error???

[Samuelbrownfield]

Sorry for the potentially obvious question, but I can't find an answer anywhere.

What exactly does tooth length error mean?  That there is too much gap between teeth, or that the air gap to the sensor is off?

I have stock VR sensors on 944T, new VEMS install and getting those errors at >4500rpm.

Well in case any one has this same issue, installing a FAE sensor with the same gap as the Bosch and Facet sensors I had tried seems to be fixing it.

I will rasie this topic as I need to solve this. On several 944 Turbos (all with same "auditrigger, 132+1 VR)  customers have had tooth lenth errors. Always at around 5000-5500 rpm. Tried several different sensors, several different sensor gaps but no difference.
Before sending out I always bench test the ECU and it works fine.

Please instruct what should I provide in order to resolve this issue.

Did you remove pull up resistor?

[PeepPaadam]

You mean R30?

One should also know the software which is behind this error

[PeepPaadam]

Firmware 1.2.32, always the same base config (I make PnP adapters for 944 Turbos) and out of 50+ pcs made 3-4 have had the issue. Others have no issues with trigger errors, clean as whistle up to rpm limiter 6700-7000 (depending on engine mods). All adapters, VEMS units etc are identical regarding config.

Should I try to remove R30? Use series resistor?

[fphil]

I meant the software lines of code, because there may me a threshold which detects that the tooth length is longer or shorter than expected. Hence there may be little depending on engines to have the error raised or not

[PeepPaadam]

Ok, how can I help/what to do to help to determine this?

Wiki / Vemsupport?

[PeepPaadam]

Ok, but what should I provide for it?

[fphil]

I think it is said somewhere on Vzms.hu. At you should create your own wiki page on your speudo name.

Did you ever find the sollution to this issue Peep?
