    • BMW F30 340i blows motor after switching to PTF Bootmod3 Stage 2 B58 tune - First blown tuned B58?

      PTF's (Pro Tuning Freaks) Bootmod3 B58 tuning software recently exited beta but perhaps it needs more time in testing. Unfortunately, this BMW F30 340i owner blew his motor after switching to the PTF BM3 Stage 2 B58 tune and going WOT.


      So this is how it started I was doing a pull down the road using my new bm3 stage 2 tune I have an

      I started the pull at 50 mph and went to about 5500rpm before seeing a huge cloud of smoke out the back and what sounded like dropping a bunch of nuts and bolts on the floor

      Sounds like he installed the PTF tune, took it for a spin, and then his motor threw up all over the ground.

      He was running a JB4 successfully before this.

      BM3 log before failure:


      Will PTF help him find out what went wrong? Will there be any assistance with repairs? Is the software to blame? Are they actively trying to get logs and address this? Have tunes been recalled until it is determined what went wrong?

      Well, we are about to all see how ProTuning Freaks handles this.

        I think you should be less worried about being a fanboy and more worried about how PTF addresses this issue.

        AFR looks fine. If you're referring to the spike in afr during the shift, thats normal. Take foot off the throttle and no more fuel is injected.

        Imo this is a case of bad gas.

        If a tank of bad gas can blow the motor, then imo at least the tune is to blame.

        You gotta pay to play, but id expect the company to shoulder some responsibility here

        Yeah, if it's that aggressive it has no business being in a daily street car.

        These tuners try to show they are 'superior' with higher dyno numbers. I mean is it a coincidence PTF OTS tunes have higher WHP and torque than many other OTS tunes that haven't shown lean conditions or engine failures?

        You tell me.

        They won't. This is what I tried to warn people about a long time ago. More to come...
