I don't know squat about Spyder (YET!

), but being a computer programmer for many years (30) , I can officially and confidently state that with any software modification there is a REAL possibility of screwing up things that are TOTALLY unrelated to the intended change.
I've done it, I've seen it more times then I care to remember!
Only a very thorough testing, which MUST include "negative testing" (which is intended to prove that your modification for added or modified functionality did not break anything along the way that was working properly before) will guarantee success.
Unfortunately, "negative testing" is a weak point in MANY if not MOST software shops, no matter what industry!
With 5 ECUs on the Spyder - there is no telling what can happen when software is updated!
No offence, Lamont!
SO, providing that there is no other mechanical cause - I am with Burg650 on the chance that Software could cause it. He seems to be a very thorough guy who pays attention to little things some others do not.
On the other hand - if the software update had "side effects" (which it really should not) - it must have been public knowledge, allowing people to make a choice whether to subscribe or not.
I hope you get this resolved! Good luck!
Try talking to RUSTY PALMERs in PA.
Seemed like nice guys (at least the sales. Gave me the best price too!)
