A short ( I get carried away ) page on the 996 eproms and problems we have them. This has been on by recent events ( me being ) and things that were during. I hope it-s not too

I was asked by one upset customer-s why it takes so long to find out if a has problems or not. The question was by her husbands non response to my request for I rang him a month after I the chip and his response was that he ridden it much, that it was from what he could so far, but he was going to ring me he had ridden it more.

As some of you are aware, we don-t know people think if people tell us.

Anyway, I-ve digressing already. We have had problems with 996s and we have fitted to them. issues are usually very and may be affected by something else I had considered.

I also have the that, being a representative of an dealership, what I say gets against me later on. If anyone who with me ever gets the I-m a little jaded, that-s with the public for you.

The issues with the 996 have around since -98, but been very on and off. One odd aspect of this is that the about these bikes drives me absolutely nuts no one has complained about. The first bike we had was wacky with the chip, showing a steppiness ( for of a better term ) to the low speed This is a characteristic of the std eprom.

Then I played with the cam fitted a FIM eprom and got a bike went great and ran just as

The first bike we played the cam timing on also ran great. we started to have problems. to Duane at Ultimap ( FIM-s new ) I found out that the software ( algorithms ) used in the 996 eprom was to the 916/748. This appeared to the steppiness. Duane-s first was to make an eprom that 916 and 996 chip software, which I had in our shop bike.

For some it was fine, others had problems. We some Ducati Performance ( not adjustable ) with varying Given the mapping the DP eproms had to the FIM eproms, I tried to stay from them anyway. revised his eprom a few times, with varying results.

people loved them, not. Any problem would between 3 and 6 months to come up so it was a slow and annoying process.

The problem has always been a or misfire when the throttle is on at 3,500 RPM. How bad it is varies, what I-m not really sure. on overrun was another problem could get some owners The next issue that up for me was that when Duane an eprom for a bike, he insists a few things are done to the sample to make sure it is set up right.

One of those things is setting the cam to spec. Given the range Ducati obviously feel is for std cam timing settings, this was the way the bikes were set up quite a bit and in my opinion, rather misrepresentative of the as bike.

Now don-t ring or me and tell me you want your cam redone for free under Ducati do not see this as a problem. The thing to remember before you go dealer like a pit bull is the warranty covers bikes original equipment only. A little phrase that their arse ( …? ) nicely.

If it-s not standard, not warranty. OK.

This cam timing is shot down by the fact one of the bikes I had dialled the cams on had this problem. The cam timing we use is different to the factory specs. I spent many hours trying to get this bike right, wiping out any profit we on the job originally. My last effort one of Duane-s later eproms, according to the owner helped a lot.

Personally I wasn-t happy with it, but it appears the is, and that-s the main aim.

By stage I was trying to get Duane to a bike as it came out of the box, but is also based on the idea they are consistantly incorrect. we are not sure is a valid assumption. And you thought this was easy

Then something else up that, while very seemed to work very

When the 996 was first introduced, I they came with injectors per cylinder because needed it. As all the SPs have had duals, I think about it too much. had mentioned a couple of times he knew of people running as single injector bikes 916 eproms with one injector

Supposedly they were great, with none of the we were having.

Then who needs to remain nameless me ( he works in something we refer to as an tower ) and said have you a std 996 recently. He went on about how bad he it was and how much better it ran with a 916 and one injector disconnected. I had asked to send me one of his new dual injector to try about this time, but he me a single injector version ( which is his way of getting me involved in the process ). This required minor changes, due to the dynamic in opening one injector for longer as to opening two for half the time we

Anyway, we got the eproms, disconnected one per cylinder and away we went. Our shop demo showed all the we had been having with the FIM so was a good model to work on. It was happy. Then I tried two patient customers who had been for an eprom for some time.

One had used an earlier FIM eprom he bought the bike. He hated the way it at 3,500 RPM and backfired on overrun. He did the way it went when the throttle was however. The other we had tried on the pre test ride, deciding to the FIM eprom out and wait for something

The wait was much longer we expected, but now we think we are there. have reported improvement, is what we expected. Duane has this eprom to another also, who-s response back to me as horn. Got to be happy that.

Duane currently has 996 to test, so a refined version of chip will hopefully soon.

At this point of you are probably screaming about the running lean. Well, the new the 996 powered ST4, runs a injector per cylinder. The same as the 916, and one half of the 996 pair. is probably Ducati-s way of saying And don-t think the ST4S is a 996 either.

With a new inlet cam shuts the valves about 10 earlier ( another factory of something we have known for a and also fitted to the Monster S4 ), is claimed to be MORE powerful @ 117 Hp the 996 STRADA engine @ 112 Hp. The 996 dual setup has more to do with SBK rules than what the actually needs I now suspect.

The theory with this is the dynamics of two injectors firing the under throttle area creates a problem. The SP/SPS have used this injector set up for a long time, but have always run the older P7/P8 ECU, which the dual pick ups and none of the issues it would seem. The software can use a single injector for low rates, then switch to injectors at a higher, preset ( between 4,000 and 6,000 RPM my experience trying to solve a with an SP ). It must be that the area is in the single injector range on these engines, its appearance. As for how the 996S works, the SPS engine run by the 16M ECU, remains to be ( do I sound confident? ).

The ST4S, as a issue, runs the new, compact 5.9M ECU ( as does the S4 ). This is a flashloaded ECU, the SS ie and Monster ie series, but is much How it works in service will be in the future.

I also alluded to problem earlier. There is a rather significant variation in the rate of the fuel injectors. 10% was the figure Duane gave me. At point I pretty much about giving up. We try really to get these things spot on, but that I couldn-t account for seem to creep up, particularly I am playing with bikes I modified.

How much of a problem is I don-t know.

Duane went on about the they had in the early days he worked with the Ducati Team. Back then, no one really knew too much and any could go from mole to mountain in an instant, injector rate mismatch was a real The bikes being raced in were probably kitted up SPs at time, and bits or info all that easy to get.

To get that were matched in flowrate, DDT would buy sets of for Aston Martin DB7 ( I think ) and all 8 of them until they 4 that were close in flow rate to be useful. The variation was over 15% in those according to Duane. The reason were buying Aston ones is that this was the only other vehicle used Weber Marelli in that size.

Expensive? You Probably less than the ones, if that was any consolation.

I think I got a little carried
