MyECU P8 for 907IE: http://www.cajinnovations.com/MyECU/index.htm
I know from FHE it works in 907, ST4, 888.
Also fits other Ducs w P7, P8, 1.5 & 1.6 WM ECU like
M900ie 00-01, 851/888, some 916-996, most 748, ST2 & 4, 750 & 900SSie.
Best is to get a used chassi w the big AMP 36-pin connector. You switch PCB, looks like this:
You get the software in a mail, Windows version looks like this (older issue):
Could also be opened w f e Wordpad or similar simple text programs, here`s a part of it:
You could also alter all parameters in Wordpad. You`ll get 2 Guzzi maps to start with so you don`t start from a blank POV
& engine will start w that.
You have full access to all parameters in WM + some good new ones, like f e possibility to connect wideband Lambdas,
set A/F targets, switch to Closed Loop Mode and tune on a Dyno or road and save the result!
Also gives the possibility to tune out the 2-3500 RPM surging issue which I think is much in the OEM mapping,
those ignition figures f sure are different.
Quite simple setup & communication: PC - RS232 adapter - MyECU:
Only quirk is that it uses own TPS breaks values instead of usual percent. But there is a formula to convert that (see below).
Any old laptop will do, I got mine f free and use W98!
If you buy MyECU as a DIY kit you`ll end up w a cost of something like 200-250 Eu.
Been mapping carefully w original map as starting point, 30-40 maps later I`m quite happy w the result:
Measured at rear wheel, SAE.
Engine mods: MyECU P8, ST2 heads, polished inlets & ports, 900SSie cams, HC pistons, optimised squish, open airboxlid w KN race, F1 mufflers.
Good driveability, even 2-3500 RPM 3-4-5th gear, and good punch at 6-8000.
Not so bad f an only assDyno mapped old 907!
Dyno finetuning will follow.
