Hi Guys,
Finally got my FD started on ms3 ultimate. So im at the idle stage and its pulsing from 1000 to 2000 rpm and cant tune to oscillations out. Can some please check my ignition settings.Even better would be a .msq for an FD single turbo conversion with standard front cover and VR's

Post your MSQ and a datalog of the oscillation.

 

thanks for the response, ive added msq, wont be able to capture log til weekend, but hopefully msq will tell us something. fuel and timing are where we have been looking

 

I've not set up trigger settings for an FD, but at a quick glance nothing is glaring. Hopefully someone else can chime in about that.
If you're able to get the car to start, that's a good sign.

Have you verified base timing with a timing light?
I would start there and adjust you "#1 Tooth Angle" until matches whatever is on the pulley.
Then I'd check timing on the Trailing coils and make sure that the timing is retarded by whatever value you have in the Rotary Split table. - This verifies that nothing is wired backwards.

It looks like you've used the Required Fuel calculator to come up with a Req fue number. Unless things have changed, this feature has only ever worked for piston engines. To be honest, I've forgotten how to calculate it for rotary. In you PM to me, you said that you needed a VE of 90 to idle the car. This indicates to me that you Req fuel is off.

A couple more questions - your MSQ shows you only have 2 injectors, is this an NA car? What type of porting?
What information have you used for the injector dead time values? These can have a large impact on Idle VE since they actually add injector MS on top of whatever the ECU thinks it needs.
At low injector pulsewidths (idle), an incorrect dead time can cause the engine to run excessively lean or rich, depending on what direction it's wrong.

Verify your timing and dead times and just try to get the engine to idle fat and happy around 12:5-13.5 with whatever VE values it wants.
