ducati sp4 correct eprom

gina

Hi to all the members,
I own a sp4 with many racing components.
I would like to know if somebody of you knows the eprom number for a 1992 sp4. I have an hand made one and I would like to find the original one.
thanks for you help

According to information on this thread eprom 037 is the stock one for 92 Sp4. If you have an eprom burner. $50 on ebay, you can download the bin file and burn one yourself! 😉

Or someone can burn one for you. If you have many performance mods as you suggest, it will most likely run too lean with the stock chip. However, good place to start if you are modifying the map.

anything with red injectors is too lean with std fuel pressure, they just don't flow enough. get some bigger injectors in it.

Brad,
What would be bigger injectors? Suitable for sp4

brad black

the green ones from the strada and 750/900ssie go straight in and flow quite a bit more. you need a different eprom though.

The green injectors are rated at 330 cc/min. They can be modified though. For the built 996cc motor with single injector throttle bodies, I had someone bore them to 450.

Very interested in this modification please tell me/us more...

As far as I know the Greens are good for 65bhp each, using only two of them will allow for 130 rwbhp.
I've got a 128 rwbhp 916cc 851 running happily on single Greens with the fuel pressure bumped up, but for my 955cc motor I'm going to need more fuel obviously...
Although I've got a complete set of 916SP twin injector per cylinder TB's, I'd rather stick with the simplicity of the singles per cylinder. There's less to go wrong for a start and they'd be lighter.😎
I was looking at getting bigger more up to date injectors (to fit into my modified/out to 54mm standard single injector 851 TB's), but if I can modify the Greens it would be happy days.
