I have connected my tune ecu to the bike & when I open the throttle the max it will go to is 74% open I have taken the tank off & checked butterfly,s & they are open fully I have re set tps on tune ecu & still same so my next stop is to adjust TPS.
Unless anyone has had this before & can advise me on another way
Cheers Malc
my guess is that this is a TuneECU thing. They all read that (from what I understand). I checked 2 different tigers, and they both read like that.
Look for smooth progression as you open it - make sure there are not jumps or gaps or areas where it can't get a good reading (move the throttle really slow).
Only getting around 74% is normal. The Tuneboy documentation warns of this anomaly, it's nothing to worry about.
Doesn't make any sense either though..... :roll:
It might be an airflow dynamics thing. Once a butterfly valve passes about 65 degrees open it effectively flows the same as WFO. Most motorcycle companies know this but set their tps sensors to 100% at WFO anyway.
It's normal for TUNEECU - Hate to say it, but read the TUNEECU documentation.
Yes very true I read it about 3hrs after posting Im finding out that instructions do help
