748-996 Tuning Software (FREE!)

Let me share my experience with TunerPro and ducati chips,

I've a ducati 748R that i got he heads flowed ant the trothle bodies opened. It was a great work done by Chris Steedman CJS Race Engineering - Ducati Engine Tuning and Cylinder Head Specialist

Chris didn't had a chip for a similar bike but a Power Commander map so my idea is to burn a chip of original 748R with the PC percentage alterations just to have something to ride and then with a AFR logger LM-1 Wideband O2 Digital Air/ Fuel Ratio Meter | Lambda Sensor Controller make the final adjustments to the chip.

Everything i managed to do was with the help of desmo11....

The files from a normal chip from ducati, a 27C256, have a size of 32kb, because the chip has 8 slots of 32kb, because desmo11 uses a 512 chip is files have 64kb.

If you try to open the 32kb files in the TunerPro with the xdf file that desmo11 done to is it will not open. Desmo11 converted the files to 64kb to make it work, but in my case i had also to change the offset of the xdf file to see the rpm values in order.

One thing that i found is that i say my reader that the chip is a 27C512 the output bin file is a 64kb file.

I have managed to do the changes on the map, but now i have a 64kb map and a 256 eprom so i don't know if it will work.

Very happy you guys are using this software.

Please post any issues you guys may be having and I'll do my best to help. I've been running my bike with it no problem. I have used chips based on 916/748 original chips only. I don't use the 996 based chips due to the supposed wild advance problems at throttle movement.

I'll be doing a 2 injecter per cylinder 996 motor with high comps & ported heads soon (soon as the crank gets back from lighten/balance) so I'll let you guys know how that map turns out...

Desmo11, thanks for sharing all of this valuable info.!!
Brad has already given me lots of info. which is needed desperately because I'm a total newbie to all of this.
I'm putting a S4RS engine in my 851, made an adapter to mount the old style TPS on the TB's, have a 1.6.
I'll order the burner Monday.

[brad black]

you use a 32k file on a 64k eprom by burning the file from 8000 to FFFF. the ecu looks at the top 32k, which is either 0000 to 7FFF on a 32k (256)or 8000 to FFFF on a 64k (512). you should be able to set the start and finish address in the eprom burner software.

or you can burn a 32k file on a 64k eprom twice, once from 0000 to 7FFF and again from 8000 to FFFF. that way it has to get the info.

you can make a 64k file into a 32k file using wayne orwigs software - it has a function for that - or by burning a 64k file on a 512 and then reading the top half (8000 to FFFF) of that eprom to a file that will then be 32k.

Good info, Brad, thanks. A coupla questions. 1. Are all 1.6M OE chips the 256 type with 32K bin files, or are there some OE 512 chips with 64K bins? 2. Is it given that the ECU always automatically reads the top 32K of a chip, so from 8000 to FFFF on a 512 type chip?

[brad black]

1/ i think most or all 1.6m eproms are 512 - 64k.

2/ yes, afaihbt by duane.

[desmo_pt]

I've two Eproms for my bike, the original from ducati marked 076 and a JHP both of them are 256-32kb

[desmo11]

OK gents:

Engine Spec
36/30 valves
Inlet ports opened to 30.5mm min 1/2 port diameter
2 injector TB's (unmodified)
Airbox Filter
46/50 JHP exhaust
12.5:1 CR (2000 racing pistals 2 1.25mm squish)
Pump gas
114/109 lobe centers

Only made 130 hp this time (last was 13.5:1 and race gas) and 86 ft*lb torque (memory). This was post spark sweeps.

Anyhow here is the cal file, alter file suffix to .bin from .pdf to get the file.

[TomTom]

Some 1.6 have the information twice making it 64, although actual working memory is still 32, think it was mentioned earlier too.

[desmo11]

Tom, you're right. I use the 64k though as it was easier to set up the TunerPro definition file when I started. I can post the 32k if you want it.

[desmo11]

for you 32k types...

Sorry for reviving an old thread!
I'm just now playing with the TunerPro/Moates burner, have been doing it on a rudimentary level.

Can anyone give me a clue on how to change my rev limit?

[desmo11]

Just change the rpm map points.

That's simple enough even for me! Thanks!

At the risk of sounding even more dumb why RPM A,B,C,?

[desmo11]

No idea! I never screw with it and have never seen it at anything other than 100%.

Go figure.

[chris steedman]

Is this system easy to learn ? is it possible to remap a chip at throttle positions on the dyno within a few hours like mapping a pc3 and without pluggin in and out chips hundreds of times ?

[desmo11]

You will likely have to make multiple changes to the cal of course.

If dealing with a chip burner only, you will need to r&r chip accordingly.

I suggest, and use, an emulator though (Moates Ostrich). That way you don't have to r&r chip.

Unfortunately due to the base programming of the 1.6 ECU, you can't vary fuel or spark as engine is running (unless done with dummy MAP, IAT, or ECT sensor).

Other than that, I would expect that you can get through maps in a few hours, yes. The big thing is that you need a way to make sure that you are running at the point you are mappping (and vice-versa).

Reviving an old thread.
Does anyone happen happen to have a bin file for a 996 SPS?
I'm starting a new project and it would give me a start

Marvin, I have an sps eprom if that would help?

Hi Paul

I could read it and save it to file. Could I borrow it and send it back?
