A spec ECU and data-logger system will be made compulsory in MotoGP from 2014, governing body the FIM has announced.
Factory teams will however be granted the allowance of being able to use their own software systems, but only if they also agree to run on 20, rather than 24, liters of fuel for each race. The FIM stressed, however, that the changes will only become law at the successful conclusion of negotiations between Dorna and the manufacturers over the supply of prototype chassis and engines.
The announcement comes after months of debate about the sport's future. Honda threatened it could quit should the introduction of 2013's optional ECU system pave the way for a mandatory policy.
The impasse has effectively been solved by the decision to allow the factory teams to use their own software systems at the expense of four liters of fuel. In addition to that change, factory teams will only be permitted the use of five engines over one season, compared to 12 engines for every other team. Engine development will be frozen during the season.
With Suzuki being heavily linked with a 2014 return, the FIM also confirmed that a new factory team would be allowed nine engines in its first season.
Dorna chief Carmelo Ezpeleta said he expected a deal to be announced shortly for the factory teams to supply prototype machinery at a set cost. The FIM has set a deadline of the first race of 2013, effectively March 31, for contract talks to be concluded. Should they fail, spec ECU systems are not certain be written into the sport's regulations.
"We'll do a commercial deal with the manufacturers to have satellite bikes leased for a maximum price of 1.5 million euros," Ezpeleta told Gazzetta dello Sport. "Purchasing the bikes for others will cost 1 million instead: Honda has already agreed, probably Yamaha will do so too and Ducati is welcome to as well.
"I'll ask each manufacturer for the bikes, based on teams' requests, while I'll directly guarantee the payments."
Alongside the MotoGP changes, the FIM announced that Moto2 will now operate a minimum weight of 215kg for bike and rider. The current regulations impose only a minimum bike weight.
