You could go the route I took and go megasquirt3 with a vvt controller built in.....bit spendy but at least the timing can be adjusted to suit the CR?


oh and you can have all the telemetry on your android tablet or phone :D

Yes, and I have to learn all about that then, but many sources for it on the net.. Also i could buy a Liana ECU and try to retrieve the mapping and put it inside my existing ECU. that would cost less but not sure what is easiest.. programmer on ebay costs approx 70£ and used liana ecu at 120£ would be cheaper than the megasquirt.

why did you switch to megasquirt?

So probably solved now, changed the catalytic converter and no more pinging(yet) and way more power!

Measured air flow from the MAF -sensor with an app on my phone connected to a bluetooth device in the ECU connection. It used to max out on 65 but now after changing the cat.conv. i get 75.

I get that engine rattle with my 2011 Jimny M13A. It is getting quite expensive to be filling up with 98 octane just so as not to hear that annoying rattle. Especially annoying since the vehicle is supposed to be able to run properly on 91 octane, as per assurances by the car dealer/salesman when I got it in 2012/
