Update.......
Sooooo, my buddy that I always help finally got some time to come over and look at the tune. Now this tune that I’ve been using ALWAYS smelled pig rich at cold start up, no mosquitoes in a 5 mile radius. Well it turns out that he used the tune for his 340 to run my 470. There’s a big difference between our engines, 130 cubic inches. So I say I found a base tune on the Holley V4 for a 454. So we saved the original tune, and loaded in the other. Holy ****! What a difference! Engine cranked for a second and fired up, settled down to 750 rpm’s and the stench was all but gone.
We watched the screen turn different colors (red=pig rich, orange=rich, yellow=getting there, green=almost perfect and blue=dead nuts for AFR). The cells were red and as the engine got to temp, the cells started changing. Idle is damn near perfect and as the rpm’s went up the cells were changing colors.
Then my neighbor came over and complained about the noise, so we called it a day. Don’t want to piss her off.
So now the car is running better than ever and got to put some drive time on it.
