In theory, it would make sense...

Just with Haltech products, I would rather have the fuel cut.
The fuel cut is milder versus the ignition cut.
Remember, if you cut the fuel past the point of combustion, nothing happens in the engine.
With the ignition cut, you have intermittent spark events with the proper fuel, so you get nasty resonances - i.e. possible bearing damage - whenever this happens.

From the way ted put it no. The stock ecu has fuel cut at 12psi, you should not go past 10 on a stock ecu. Honda motor and a Mazda rotory motor are worlds apart.

I've always thought ignition cut was better, learn something everyday. I run a haltech and just updated to 1.08 i'll have to check what cut i have.
