mrinflux and Finnpaso - you both each have reasonably modified bikes...

between chips, cams and cans - yes, I'd imagine that you'd better have the things running near perfect...I'm sure you'd be pissed off if they didn't...

where i'm coming from is with the standard 907 horse - with the exception of Staintune exhausts and an Ultimap chip - these were fitted when I bought it.
I don't think I'll ever demand the full power output that the 907 can deliver reasonably standard - let alone with cams and valves...I'd just like to get it running satisfactorily, properly (as much as possible) in near "standard" condition.

I want to get the thing running like a clock all the time.

Fast is fine but accuracy is everything. (Wyatt Earp).

My XS1100 didn't handle - but i knew that before I bought it, my TZ Yams didn't idle - but you don't spend much time idling on a TZ. I think it's OK to have the Ducati character, but just expected that there would be a little more refinement in this Italian job...

pass another latte...

Guys, dont take this my comment too seriously now(!!!): I want to say "only", that Ducatis are not easy motorbikes and thats why these dont fit so well to such guys, who dont want to "play and maintain" they bikes with they own hands. Sorry, but this wasnt direct to topic, but i have seen very many times, that some "easy jap bike" is much better to such guys, who dont want maintain/fix/cure problems from they own bike. In Finland here is also plenty of such guys, who have enough money to buy many Ducatis, but they dont know anything about maintainig simple things in they bikes. Its little sad and thats why Ducati club of Finland have divided also to 2 parts: Those, who buy new Ducatis(cant do anything to them) and those, who have older modells and do everything to they bikes. Line between those groups is very high. I dont want to make anykind war of this thing and this was only one comment to taughts, what came to my mind, so NO need to comment this my opinion.

Fabio Taglioni: "I dont want to make easy motorbikes, i want to make difficult bicycles" :thumbup:

Anyway I pray, that Laddie(with hiccup problems), Gert(with better ECU), etc.... can get they bikes to very good conditions, cause seems, that at least You both have plenty of "knowing" and energy to figure out things in Your bikes. I like thatkind behaving alot! Keep going.... :thumbup: :thumbup: :thumbup:

Thx, Antti, and surely not giving up before my bike runs good. :thumbup:

Gonna get sync clocks and carefully sync esp at 3000RPM`s and to be sure, get another check w the Mathesis tool from a second shop that my whole ie system is OK.
Then, who knows what will happen....

Fast By Ferracci also makes
a chip that some posters have used, but many have since switched to the FIM
version.

Apparently FBF uses the "some is good, more is better" approach to
engineering (if you call it that) their EPROMS. On the Duc EFI systems the
CPU basically does a series of table lookups. On the 907's 6801 based
processor these table lookups produce an injector values from 0-255 to
indicate how long to open the injector -- for a richer mixture, they just
spray for a longer time, for leaner, a shorter time. According to Duane at
Fuel Injected Motorcycles, all that FBF did was to do an across-the-board
bump of all of the values in the table. He claims that if you look at the
table lookup outputs a lot of the time under acceleration you'll see 0xff
[maximum value] outputs when that is really not appropriate based on an
exhaust gas analyzer. The upshot of this is that the bike tends to run
richer and mileage suffers. According to him he does his EPROM tables with
a brake dyno and EG analyzer setup. When running with the FBF chip, too
rich is what seemed to be happening. It wasn't uselessly too rich but it
was noticeable. Side effects of the too-rich settings, however, are carbon
build up in the exhaust and crappy mileage.

Ducman -

I guess that as not all bikes are not alike, not all chips are alike...nor can you expect they adequately give economy and performance, smooth running and all the good stuff in one chip. They are usually purpose-built - you just need to find out the rationale behind the design...

The "rich" chip may well have been designed by a petrol-head for (say) racing back in the dim, dark ages of EFI technology.
This "more is better" technique also suits Finnpaso as he riched-up his EFI 7.5% across the table and is happy with the results...as for full duration squirts under acceleration - maybe it seemed like a good idea at the time??? (I bet it back-fired when you let go of the throttle!!)

I know the first thing everyone has tried with my 907 is to dial up the fuel somehow to make it run smoother.

In the racing fraternity chips are often revised as performance data and feed-back comes along, but usually no two bikes are alike in modifications - so the programmable systems (like a Jeffries) are a must. Similarly, you might find that a chip has been designed but is no longer supported due to lack of numbers of users / buyers. I'd imagine they don't sell too many chips for 907s these days - except the dusty ones...

The Ultimap gear is continued to be refined - the latest 907 chip I got from Duane was "new" only about 10 months ago - nearly 15 years after the 907 was built...at that time I was doing a process of elimination to solve my problem and I figured the ECU and chip needed to be a bench-mark steady platform. I don't know the map was modified significantly but the chip itself was - it's a piggy back style. (looks like two centipedes fucking). The fact that he's still developing products for a machine like a 907 is encouraging...a lot of other parts (like the ignitors) are unobtainable, let alone improved...

Duane has been very helpful to me with testing my ECU and helping me with chips and is certainly well respected here in Australia in EFI circles. I'd be cautious about pegging one brand against another (and quoting part of the discussion) as a basis for deciding what will work well and why. [Particularly in open-forum]

Laddie, keep going on with Duane and with 907 chips! I have heard, that he is great guy and helpfull.... Pitty, that i really dont know his @mail address to ask some questions from he ;-((( If someone know it, please send me PM! :thumbup:
