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?
You mean R30?
One should also know the software which is behind this error
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?
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
Ok, how can I help/what to do to help to determine this?
Wiki / Vemsupport?
Ok, but what should I provide for it?
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?
