Renix 44-2-2 and wasted spark

Post by red-racing »

Can someone fix the problem with renix mode (44-2-2) and wasted spark? running single coil works fine, but when switching to WS, RPM goes to 0

Renix wheel wont be able to run Wasted Spark, because renix wheel only has 180 degrees of resolution

Cam sensor will give you 720 degrees allowing you to run fully sequential, but this feature is not avaliable for renix wheels.

If you are running a renault, find a late gen clio toothed wheel. It bolts on without any mods in replacement of the renix wheel and you can use the same VR sensor.

yes it is working ! with 44-2-2 and 66-2-2-2... just add cam sensor. (it is explain on the microsquirt manual)

"Typically Renault installs utilise a crank sensor only and output to a single coil and distributor. Wasted spark or coil-on-plug require a single tooth on the cam and a cam sensor. The cam pulse needs to occur before the missing tooth region that precedes TDC#1 firing."

Can you post a copy of your tune file and a composite log of an attempted start? I'd like to check if you're just not picking up the cam signal.

Rennix mode requires a cam signal for wasted spark. Without the cam signal, the pattern repeats itself every ignition event, and so you have no cylinder identification.
