Have been running the latest eprom for about 3 weeks now,(got from joe),and promised review to some of you.It runs very clean.Did not think an older stove could run this clean.I could adjust the trim pots so much that no ash/smoke on glass,pot looked like a forge furnace.But also had poor heat,as most was going up the stack.Tried lots of settings over periods of time,love it.I can see if I ever get a bad batch of pellets,again,it will not be a problem.Start up sequence is very different,but works good.Is definately set up well for an ignitor(which I do not have).Do not like the fact the convection delay is longer,but liveableI would reccomend this to anyone that has an older integra.Bob PS Cleaned stove,installed eprom,weather has been -30 to 40 above,took apart and inspected before writing this.
