No they do not. It just sais make sure ignition is in OFF position.

 

Considering the fact that the Hypertech is recalibrating the existing sensors here is what might be going on. The truck may actually fire a little rich, not enough to trip a code or cause any issue. I remember my Gen 1 sometimes would do this when I was running the SCT on 87 program. I have been running all 93 octane since installing the HT and have no issues. I dont think its anything to worry about.

Hmmmmm

 

Update

Tried to remote start my truck yesterday morning and temp was around 33 degrees....didn't want to turn over and start. I could hear it really try, but it hesitated and just didn't start. Wonder if the combo of temp and running 93 octane is causing the issue? Temps likely won't get that cold again anytime soon...so i guess i'll have to wait till the fall. Love the Hypertech....so i guess we'll see what happens.

 

Did it crank? or did it struggle to crank?
Has anyone called Hypertech support on this yet? Their customer service has always been spot on.

I too notice an ever so slight hesitation during start-up occasionally.

 

I just read over on Jeepgarage.org that a few guys have said they contacted Hypertech and there was a batch of units that went defective over time and they were offered to send the units back to Hypertech to be fixed.
If anyone is going to contact them you need the serial number of your interceptor when you call
