RG3 slip on & EPROM on 2004 F4?

greenspun.com : LUSENET : MV Agusta F4 : One Thread

Greetings All. Have had a look once in a while but never submitted a post, but have benefitted from reading, so thank you very much (I mean it). Just sold my 2000 F4 to a very nice chap called David over here in Dubai and my 2004 has just arrived, should pick it up on Saturday.

The question I have is will the EPROM and RG3 slip on work at its best with the 2004 bike. The reason I ask is that the EVO 3 bikes and onwards have more power, lighter crank, improved valves etc and I wonder if the mapping is different or does it not make any difference?

the RG3 will improve the bike's performance, but your dealer has to order a new eprom, he will need your frame nr for this

Go for a powercomander - can then be set up to work in the real world of your bike instead of a compromised one of 'averages' and 'cure alls' that preprogramming requires. And can easily be remapped to suit any future changes you may go for.

Jacob and Mark Thanks for the reply, i will probably go for the factory CRC EPROM, as although a Power Commander will be ultimately better, a proper shop to set up and map does not exist over here. Best regards

Sean, Stay away from the factory Eprom. It's crap. I had one and dumped it in favor of the WCT chip. To me, the only other alternative is the Power Commander. Dean

Hello Dean,

what is you advice for the best tuning of the SPR?
