P0068 code on tuned vortech help please

[Frs32907]

Replaced sensor and tightened all the clamps to make sure no leaks im going to probably switch the vortech clamps out for T bolt clamps

@Frs32907 did you replace the sensor with another 2.5bar? or did you switch it to a 3 bar? I recently got a new tune and have been having the same issue throwing code P0068. How's the car running since?

Did P0068 shut down your cars? I received it last night and it shut down my car and wasn't able to restart afterwards. I have a Kraftwerks S/C installed and recently updated with new 4-bar MAP sensor and new tune which worked okay for ~2 weeks.

That code relates to your MAP sensor scaling I believe, but I can't see it shutting your car down unless the sensor actually failed. I know I installed a new MAP sensor without modifying my tune with the correct MAP sensor scaling and it wouldn't even start.

Well, I have a Delicious tune (the Kraftwerks (KW) factory tune) but the failure didn't occur on it. The Delicious tune was based on a Denso MAP sensor, but the tune itself was rather rough so I asked KW for a better tune. The failure actually happened on a KW/Skunk2 tune (later clarified it was indeed NOT a Delicious tune) with a new 4-bar MAP sensor.

After checking for loose hoses etc tonight or this weekend, I will be installing the previous Denso MAP sensor and the Delicious tune to see if it fixes the problem.

No issue with my car shutting off, it would just throw the cel and an occasional slip light. The issue I was having was the values for the maf voltage weren't set up correctly so that was causing my car to throw the cel. Since adjusting those I haven't had an issue.

I could see that causing your car to shut off if your MAF voltages went out of range high, but I don't see that not allowing you to start your car afterwards.

Sounds like a good plan. As I mentioned I don't think loose hoses will prevent your car from starting either.

Thanks. Yeah I've been following that thread... the symptoms that I experienced do not seem consistent with the experiences in that thread. I'm kind of hopeful that it is as simple as some tubes coming off that need to be secured. If not that, it might be the MAP sensor. If not that... I'm SOL. Thankfully the FRS isn't my only car or else this would really be annoying.
