2000 S3 snatchy throttle

Is it the throttle/cable that is snatchy or the engine fuel delivery.
If the former, then a good squirt of WD40 down the throttle cable may help loosen things up if it is a bit dry

 

If it's the delivery I'd first check that the map loaded is the right one for your exhaust / air filter / SAI setup.

 

Probably throttle bodies out of balance.
If you can go and see Clive Wood in south Lincs (Swineshead).
When running Jack Lilley's race team he had instruction from Sagem, so knows more about the efi than Triumph dealers or even the factory as they just subbed the work out.
Even went testing with sagem at Mira with data loggers etc. If anyone can get it right its Clive. 07752477738

 

You can find what map is on by the free (for windows) Tuneecu program and a quality OBD2 lead. This allows you to load new maps too.

 

It does work with Sagem triples amongst many others but the earlier S3 955i models don't have the amount of maps as the 1050 or the 955i Daytona. There's approx. 4 each of OEM and custom maps.

 

I can defo recommend the Lonelec cable, have that along with the Android version of Tuneecu. It's easy to use from my cheapo tablet. I mentioned about 8 maps for the 955i S3, that was for the 02-04 model, your Vin, last 6 digits on the frame will tell you which maps are available for your bike. I changed the tune on mine for a slightly richer one when swapping the TOR can for my race can.
