Default Traction Control Issue With Port Injection - 03-27-2018, 06:34 PM

I just installed an mmp port injection kit with the JB4 PI controller. I set all the fuel bias to 50 and the WMI scaling to 100 like the insctructions said. I currently have 2 step so I left menu 8 in the JB4 alone. I have the E85 backend flash. Im running E60 ish right now.

When traction control kicks in the car bucks really hard and then is fine. I didnt get this before the port injection. This cant be good for the car. I was wondering if this is a common issue or if it can be fixed somehow? Thanks!

Sounds like it's doing its job. To run pi u really have to be making 500+,which is plenty to spin tires at 40mph. I know if I try to floor 2nd with traction on it does the same thing.once disabled it just spins tires really
