Better ECU, More air and fuel pressures -- for better atomization.

I notice something about Tohatsu Tldi's,how come they don't complain about injector problems or ethanol gas like on some other DFI posts or sites? Or that you can actually use some competitors oil with the blessing of Tohatsu unlike some competitors mechenics will blame diff. oil for a blown powerhead.Hmmmm

Durability is a top criterion for Tohatsu. The TLDI was developed with commercial use in mind.

As such, it is a mature, nearly bulletproof design. Yes, ethanol can be an issue, but if you follow the rules, it's not a problem. You do need DFI-rated TCW-3 oil. But, since OB manufacturers don't make oil (oil companies do), as long as you follow the DFI spec, the TLDI will actually work on a wider range of oils than some of the competition. In the US, the only way a motor company can require a specific oil is if they provide it to you. So some mechanics can blame an oil, but they can't invalidate your warranty, as long as the oil meets the appropriate specification.
