Adamw Posted May 8, 2021 Report Share Posted May 8, 2021 Can you attach a copy of the tune as well. From the short triggerscope capture it suggests you have some trigger settings wrong. Quote Link to comment Share on other sites More sharing options...

Adamw Posted May 8, 2021 Report Share Posted May 8, 2021 You originally said it had a 36-2 trigger wheel, but your map is still set to MX5 which only has 2 teeth on the crank. So your trigger setup should be something like below. If it still has the 3 teeth on the cam and you want to run direct spark then you will need to grind off two teeth (so it only has a single tooth left on cam). Or you can wire coils in wasted spark configuration and set sync mode to none, then you wont use the cam sensor. Quote Link to comment Share on other sites More sharing options...

As I am running coil on plug due to limited space, I think I will need to grind the cam down to one tooth but will look at running it with a wasted spark system. I will have a play and see what works best, out of the options given. Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 8, 2021 Report Share Posted May 8, 2021 You can still run COP, just the wiring would need to be changed a little to make them spark in pairs. For wasted spark, coil 1 & 4 get triggered by IGN1 and coil 2 & 3 by IGN2. Quote Link to comment Share on other sites More sharing options...

Thinking about this further, If I returned the crank wheel from 36-2 to the stock wheel, I could run a stock MX5 basemap which would be simpler? We replaced the stock though as whilst we were getting a good scope pattern we were not getting fuel or spark but when requested to fire as a test both would work. I am guessing this could be down to the fact that prior to going COP, the MX5 ran a wasted spark system. I know/think that elimination of the cam sensor would mean having to change the injection mode away from sequential to multipoint group (I think that would be the appropriate setting) but by grinding the two teeth of the cam wheel will this have any effect or can I still run the injection mode as sequential?

If your stock trigger is from an NB then you would need to use the NB trigger mode. 11 hours ago, Icedmunkie said: I know/think that elimination of the cam sensor would mean having to change the injection mode away from sequential to multipoint group (I think that would be the appropriate setting) but by grinding the two teeth of the cam wheel will this have any effect or can I still run the injection mode as sequential? If you run no cam trigger then you will have to use wasted spark ignition and multipoint group injection. If you remove two teeth for the cam then you can run direct spark and sequential injection.
