How to remove Rev-Limiter Piasini ECU

Well this mod has been a long time coming. With the resources of Richard I was put in contact with Christian from R&D Piasiniengineering who specializes in remapping & engine performance tuning. Christian took up the challenge of remapping a standard XT660X ECUs to move the rev limiter up in the rev range, after a few months of info back & forwards, Kris my mate here in Brisbane sent his standard ECU to Christian looking for a 8000 rpm rev limiter, it was remapped & sent back within a week.

Kris & I had it on the dyno this morning & this was the results we got, a new rev range up 7700 rpm where a standard XT's ECU has never gone before, Standard is 7200 RPM this is a worlds first for the XT660, remapping a standard ECU.

I did hit one problem with the Power Commander after the new rev limiter was done & that was it can only be mapped to 7500 RPM with the XT660's Power Commander, with a quick email to Martin at Dynojet UK & he sent me a 10K RPM base map to load into the PCIII & that sorted that problem. There was no problem mapping the new rev range between 7200 & 7700 RPM with the PCIII.

Here is the dyno run with a before & after remap.

The ECU was flashed to the blelow spec's
Advance +3 degree on all the range
Fuel +3% from 1000 to 6000, and -2% from 7000 up to revlimiter
Adjust revlimiter to my guess to 8000
Nothing else

Kris's build.
Standard motor 04 XTX
Stage 2 Hot cam
K&N + stage 2 DNA filter, snorkel removed.
Cans
PCIII




With this new rev range we will see bigger HP XT's come out of the wood work. Christian will be able to set your rev limiter any where you want it.

I would like to thank Christian for his help on this matter & look forward to future remapping developments with his company.

Kris will be along later to tell you what he thinks of his new rev range.

The cost: 440 euro - 25% = 330 euro (included shipment back with UPS express)[/font]
