How can you tune an HEI?

Set and verify the curve. Test the coil and all functions. Dynamic testing off the car. Test the vacuum advance. Think of it as a dizzy dyno.

FI with ESC, knock sensor....

case CLOSED.....

:hunter:

:trumpet:Some don't worship your decision. Case re-opened.:harhar:

I would agree with you Bird...especially in the case where the system needs Techron additivie just to get a proper idle. I guess the good old fashioned system of adjusting the advance rate/AFR manually is too low tech:huh:

:smash:prrtt:

YEH I hear you on that ok, but when I first had this car up north, I stuck a dead stock L98 on the OEM L48/muncie the car came with....336 rear, car went from 14 mpg to 24 mpg.....almost doubled....20 around town....

but that was up north in the land of decent gas...here in Jacksonville, I can't figger what if hell is going on, but it's all fuel related...has been almost since I been here....everything from water in the tank down the list....

After 105,000 miles in my 2003 Silverado, it started to "hunt" at idle. A large can of Techron (mixed with 20 gals fuel) made it go away.:huh:

Well??? Got it working yet?

YES, I figgered out the idle problem....water in the fuel...about a gallon in bottom of the tank....question is HOW and why did it get there....

Glad you got the water out. How'd it get in there....must be a bad gas station? You filled up just as the service station tank was low and had water in it......dunno.

Jeff.....Sun Machine working?
