Fuel pump troubles

[mike327]

Just a quick update. Jeep has been running fairly well this past week. I've had it on the gulf coast @ cruisn' the coast, riding up and down the beach looking at all the cars in town. A ton of cars from TN. I was having trouble keeping it running in all the stop and go traffic so i reset fuel psi back to 13 psi and flash a bin that came with EBl. Then I done a few learns and it smoothed out real well all things considering. I just drove it the week cruising around, no burnouts or racing. DC% stayed well below 50% and BLM stayed between 126 and 130. When I get it back home I plan to get down and dirty with this tuning because I have got to be able to do a little racing with other Jeeps and a few unsuspecting cars.

Nobody ever post a pic of what they are working on so here it is, nothing special just something to play around with.

Update! The Jeep has been running great as for as daily driving goes. It still needs a little work as for as performance goes. It just does not have the acceleration that the carb had. Why does my timing retard when I accelerate? I thought it was suppose to advance.

The ECM retards the timing when the engine is under a higher load - ie at a wider open throttle. It advances it when the load is lighter (higher vacuum aka lower MAP sensor readings)
