I have a really bad hesitation at about 3000 RPM when accelerating at low boost. I never had the hesitation before when I had my Power FC. I have been using James Paventi's (thanks James) maps in the other thread as my base while I tweak the maps, so I don't think it is a tuning problem. I know for many who had this problem, it was on their stock ECU, and grounding helped many. I have installed a few major grounding straps even when I had my Power FC, so I also do not think grounding is the problem. Really the only thing that has changed is the ECU, so it is making wonder if it is something in the Adaptronic unit. I was curious to see if anyone else has had this same thing happen? Thanks

 

Add more fuel on the cells that are producing the hesitation to see if anything changes, or you can add more fuel to the whole map using the master trim, if by doing that it fixes the issue you know that you fuel map needs to change, just keep track of any adjustments so you can go back to the fuel map and only adjust the area that you need.

 

Take a log and post it along with your ecu file.
