Intermittent Code 61 Ideas - ZR-1 Net Registry Forums

The casual reader of this and other ZR-1 boards quickly pick up on the fact that the 15-20 year old vacuum circuit is one if not THEE most common nags associated with the LT5s.

Parts not used don't cost anything and they seldom break!

I'm using Marc Haibeck's secondary elimination chip b/c it has several other drivability features really worth the $$: The fans come on early, the idle, especially on startup is handled nicely, fueling and spark advance minimize power loss when the engine is at normal op temp, and a couple more features too...Not to mention no more finicky secondary naggings! Eliminating the damn things is a consideration. And, there just might be a few more ponies in there when the throttle rods and plates are out of the air stream!
