I am puzzled, I have been tuning this thing and I keep hitting a wall. All my searching hasn't given me a definitive answer. Its a 2001 Truck PCM
This is not a final tune. I haven't smoothed or finished the VE. At cruise all my StFT are +/- 3 ish. If I go up in boost level or give it a little hit, all across the board everything goes rich and stays rich. The LtFTs shut off, the stfts are trying hard to bring it back to stoich. almost -20 ! There is a setting I am missing or maybe I need to reflash, you tell me. The log I will post shows this happening. Just cruising then tip in a bit then BAM! Rich. If you shut the vehicle off, wait awhile then restart then it will go back to being "normal"
I currently have PE as the main adder and BE more as the Safegaurd. I do not like this, I just tried it and will put it back to BE as being just solid boost enrichment. I dont like 11.2 AF when I am at not throttle near 105kpa.
My AF reading in the chart is off. Its .6 off. so its running 14.6-15.2 AF ratio. My WB shows the correct numbers, the Chart doesnt. SO at a good hit it goes to 10.1 AF ratio which is WAAY off from my target. Thats the other issue I am having. Boost referenced regulator so in boost 7psi its about 65 psi fuel pressure. Its always rich. No idea why. I took a ton of fuel out of my VE in boost areas with no change.
Thanks for any direction. I may rewrite entire tonight
