Default Problem with my b58 jb4 - 05-20-2019, 12:29 PM

Ok so my car is slower than a Prius and I can not figure out why. Anytime I press the peddle more than about 30% my car feels like it over boosts and doesn't build up after. I have installed a *** less **, BM intake and the JB4 but my car continuously is in drive train malfunction code every time I try to read codes it just says invalid read. I'm not to technical and don't understand logs very well could anyone please help me out I've been driving like this for 7 months now nothing works. Plugged a obd reader and no codes got brought up obviously besides the cats. Anyone ever experience this problem.

Do you have fuel(FF) and/or boost(EWG) wiring harnesses installed?

Weird jump in RPMs, could it be clutch slip?

Did you try removing JB4 entirely?

Ya I removed the JB4 entirely and had it sent over to Terry to take a look at. In the process my car was still acting funky but honestly shifting feels good my clutch doesnít feel like itís slippimg or anything.

It could have been, but if you only connected to MAS and MAP sensors, then you don't have them. I only asked, as you had low settings on EWG Bias and high setting on FOL. Terry will get you fixed up. Looking at the log, it's acting really weird. I'm sure terry will get you straightened out quickly.

Update to v13 firmware and focus on reading codes, those will tell us what is wrong here.
