Has there been any progression on this? I am looking to use speeduino for my k series. is it possible to run using standard sensor and flywheel rather than fitting a 36-1 wheel? I have the 0.4.3 board with vr conditioner

Not heard anything :-( perhaps you could put in another request on git for the feature!

Any progres? Is it posible to run vvc with vvt output? Theoreticaly it should work if we add cam trigger, and know the specs of the valve...

I'm going to have a watch of the video on making trigger patters again. If it makes sense I may have a play.

Have a search on the Facebook group.
Someone did write a working mems decoder a while back but never submitted a pr for it via GitHub.
It may save some time rather than starting from scratch.

I've started working on this. Just working on getting the trigger wheel working (not cam) initially.

In theory i think i can get both the 1.9 and 2.0 mems working on the same speeduino trigger pattern which should be nice.

So i got this working, but got distracted by an idea for a generic trigger wheel. Figured i should park the distraction and get this available for people. Its been tested on my desktop, and i've checked spark events appear to trigger correctly & at the right frequency. Its compiled against the latest 202012 firmware so you'll have all the current features.

The code should support all 4 different rover trigger wheels & the half moon cam.

NB i'm not promising this will work straight away. You'll have to help debug. I could have a range of things slightly out, like which tooth corresponds to TDC etc. This won't be a simple download with speedyloader, you'll have to compile the release as we need to prove it works on an engine before its incorporated into the formal release.

Is anyone prepared to help test this on a real engine?

I would be really interested in helping out as it would help with many of the projects.
I have all of the following. I am about to buy speeduino so please let me know that we can work on sorting this.

K series.
Mems1.9 - 1998 MGF 1.8. 120BHP

MEMS2J - 1997 MGF 1.8 VVC. 143BHP

MEMS3 - 2002 MG TF 1.8 135

MEMS3 - 2002 MGF 120

MEMS3 - 2004 MG TF TURBO 1.8T

MEMS1.6 - T16 ROVER COUPE
DIZZY CAM SENSOR AND CRANK SENSOR

MEMS1.9 - T16 ROVER COUPE
WASTED SPARK, CRANK SENSOR ONLY NO CAM.

I have all the flywheels, now I know depending on different ecus mems1.9 can have 4gap or 2gap flywheel types which depend on ecu.
I hope this list helps explain flywheel types to ecu and mems version.

I figured their are actually 4 flywheel patterns used by rover. The code automatically handles them all.

What we need is someone with an engine to try the code. It appears to work on the test bench but we need real world proof before it can be officially merged into the code base.

Of you want to try it, let me know when you're ready.
