I bought a 996 track bike a while back and it needs a LOT of tlc so I have started going over the engine bike and now I'm at the ECU. I wanted to know what kind of eprom it had. However I can't seem to find any information about it. It says SST on it. Does anyone know? Thanks, Tut Sent from my toaster using morse code.
SST is the chip manufacturer. Once programmed a label is usually added to the chip to indicate what map has been put onto it. identifying what map it contains will be difficult, involving an eeprom reader and TunerPro.
SST retail blank EPROMs for the tuning market. Looks like a previous owner has had some dyno work and they have written a new EPROM. Not a bad thing but fewer and fewer people are offering support to the older technology now. Logical step if the tuning is off and the EPROM is okay is to use a Power Commander PCIII USB. Works fine on my 748RS based track bike. Bugger, Chris beat me to it again. Andy
Ok thanks alot for the quick reply. I'm using a pcIII but I was curious what kind of hardware it had from the start. I'm going to switch to 748r throttle bodies and Change the eprom anyway. Will almost certainly change injectors also since we're gunning for 150+ rwhp. /Chris Sent from my toaster using morse code.
The later 12 port (purple) 848 injectors are a plug and play upgrade on the shower throttle bodies which makes the fuelling a lot smoother. Good luck with the 150hp, that will not come cheap and will require work to the heads. If you are interested, I have several sets of new Zanzi titanium 996RS inlet valves which are (iirc) 39mm diameter. Andy
Thanks for the input Andy. I have already sourced hc Pistons, larger valves (I was under the impression that 39mm valves didn't fit 996 Pistons and that 38 was max. Possibly 38,5) and 1098/1198 injectors. I'm getting titanium rods and 458 or 471 cams. The crank will have to be balanced and the heads are already ported. They will just need some updates depending on rpm limit. My friend who is an experienced engine builder has already done the simulation with different cams and theoretical HP is 202 at the crank at 11800rpm. That will however kill my engine quickly so I'll settle for less [emoji38]. Sent from my toaster using morse code.
The simulation might be of regular Pistons w/ 900 crank and stroked engine. I'm not sure but the difference between hc Pistons and stroked engine wasn't that big. A little smoother curve with the stroked version. Sent from my toaster using morse code.
I'm running 748r bored injection system and air box on my 996 and it manages 149 rwhp with the standard injectors. Chris at CJS did the mapping on a programmable chip.
Finally found the issue with the "coughing" and stalling at low rpm. It turns out that the owner before the guy I bought it from had flooded the ecu at a trackday. It dried up and the bike worked ok but I guess there were long term damage done to the ecu. I bought an Ecu and wiring before as spare and I replaced the ECU this weekend. It started ok and idled just fine. I'm really happy about that. Feels good to locate the problem before the engine build starts. I'm sure there will be other issues :grin:. //Chris
Sorry for thread jacking but would other Ducati benefit from multi hole injector upgrade (if fitting possible) ie. like my Hypermotard 1100 ?.....I'm sure they are 4 hole....
