Eproms
 

Having just replaced my eprom after fitting Termis I realised that as I have access to a prom programmer and blank eproms, If anybody wanted an eprom copying then for a few quid to cover the cost of the blank prom and p&p I could oblige.

Colin,

It's worth bearing in mind that a few of the more expensive eproms (and eeproms) have copy protection in them, so you may not be able to read the full chip with the programmer and copy it successfully.

Might be worth doing a test on your "old" chip to see if it is successful or not - your programmer should have a checksum test in it to compare the original and copy.

Tried it with the original eprom fitted in my bike and was able to copy and verify ok.

Have a question you might be able to hlep with - have been offered some carbon termi's for my 748, but not with the new chip - seller reckons the chip doesnt really need changing over as 748's run quite rich anyway ???

So... does it make THAT much difference, is it going to cause any problems running the termis on the original chip ? is the chip change just an extra to give more power etc.... or is it vital whwn you swap the cans.

thanks
mike

I was also told that I did not need to change the chip when fitting 50mm Termis to my 996s. I bought a chip with them and so I have changed it anyway, but yet to give it a try on the road.
I'm sure someone will be along who knows the answer better then me.

It depends on the size of the cans. If they are 45mm then they are a straight swap for standard cans and won't need a new chip.

If they are larger than this, not only will you need a new intermediate piece (the short double-piece behind the right-hand footpeg) to make the cans and main pipes fit together, but you'll also need to replace the chip.

Chips are £28 from your local dealer.

How much does it cost to replace an engine if it runs too lean and ends up holing a piston?

I know what I'd rather spend my money on!

Really? Is that correct? The part about not needing a new chip for open 45mm termis?

I got a replacement chip from JHP for my 45mm termis when i swapped the original cans. Was this not necessary?!?!:o

I have 748s with 50mm ti-termis and was told by my dealer i coluld ride it with out changing the chip, might not run so well but do no damage.

He also said the DP chips were better than the JHP one I got:D

You also do not need the 45-50mm mid-section to fit 50mm cans to a 748s:D

Ducati don't do an open chip for 45mm, so they assume it is not necessary!

Are you really sure about that?

I have a 748S with 50mm carbon Termis and they certainly don't fit the standard link section - I have to change the ******* thing every year for the MOT!

Yep i fitted them over the standard mid section instead of inside, where the 45mm's went.

I haven't measured them but assume the 45mm open ones would go on the inside as standard, and mine are 50mm so just fit over the outside is a tight fit though, I bought them of a member so trust they 50mm.

No leaks or anything works fine:D:D:D

Just getting back on topic for a mo .....

I'm thinking that a range of chips that club members could try out - maybe a library of chips that could be circulated to try the best one and then, of course purchase the said chip to fit your bike might be a good idea. ( i can always dream) - can you copy Ultimap chips? - for backup purposes only you understand - and in the interest of perfect running Ducatis :).

Try measuring both sets - would be good to know!

Wheres best to measure? can i measure the tail pipe? inner or outer diameter?

Or the outside of a link pipe?

internal diameters of the pipes themselves - measure both ends (end can and connector side) of the cans and then both ends of the link pipe.

You can copy anything with the right tools, but....

The thing with the Ultimap is getting it setup in the first place, so although you could copy the EEPROM, you'd still need to get it set up.

probably got it round my neck but when nelly set up my 996 with single injector ultimap eprom i asked about fuel mixture i,e rich/lean . Yes an eprom swap will alter perameters including fuel but you can still ajust mixture yourself using a base setting .just because you put an eprom on to match a 45/50 termi it dont always mean your mixtures right .so you should still av it set up

Hi antonye,

measured them 50mm and heres a pic showing the 50mm over the 45mm

and heres a bit of bling i got from Nattyboy:D:D

The problem with the way you have done it Lee1980 is you might aswell have only fitted 45mm`s.

The reason for the link piece in 50mm`s is that the standard link pipe contains baffling that restrict the flow, removing this allows more power to be released from the engine.

On the subject of chips, a lot of aftermarket exhaust companies supply systems that will run on a standard bike without chip modification and without detramental damage to the motor
The reason for the chip is this helps release more power from the engine by altering the fuel mapping slightly, a cheaper option to a Powercommander.

Ducati`s run better with a 4-6% CO.

A lot of problems with rough running occur when dealers fit cans, chips etc but do not set the fuelling up correctly on idle.
This is not restricted to Ducati`s we have many bikes with Powercommander and Dynojet kits that run rough because the carbs and injectors have`nt been balanced, it is the same for Ducati`s, just putting cans on or replacing the chip is not really enough, the fuelling needs to be set up to the right CO and within 0.5% between the cylinders.

Hope this helps dispel any fears about not fitting chips with 45mm sytems.

Yeah true mike, but these were seocond-hand hand just wanted the noise really:D:D

Fast enough, already got 6 points!!!!

I paid the dealer £10 to change chip and they adjusted the idle and said it should be ok now, can be set up for more cash though:D

It certainly goes better now to and sounds awesome!!!!!

Cool,
thats what gets missed sometimes, if your happy with the deal then thats the main thing, thats what makes biking so diverse and at the end of the day that glorious noise is the main factor.

I ran my 2002 748s for 12 months in standard form, then as the need to hear termi’s exceeded the need to keep cash in pocket 45mm cans were fitted.:devil: It now played the right tune but the fuelling / throttle response was worryingly bad (but I would expect bikes differ one to another).
A ride over to Mike Davis for a jhp chip/set up /coffee and chat then back on the bike hoping it may have eased it some. Before the clutch leaver was fully out it felt sorted so I spent the next hour trying find a glitch, I couldn’t so filled up again and took the very long way home.:D:D:D:D
For me the difference was so marked that if I ever change pipes/chips/ bikes even if standard for what it costs, and it's not alot, set up will be first on my list of things to do. :burn:
