My car was tuned today to 10psi lo boost and 12 psi high boost. I was out messing with the boost controller while driving, profec b-spec, and was just trying to figure things out. I messed around and now my car just spits and won't let me past 6000 rpm's. I can rev and boost right up until 6000 and it just spits and studders and won't go past it. My question is what did I do?? Is it something in the gain or limit part of the boost controller that I messed with. I am kinda freaking out as everything was running fine earlier. I didn't bo over 130 on the boost controller pea part which is supposed to be 13psi. HELP....

 

Went back out 30 mins later and it seems to be running fine?????
Wow I wonder what that could have been...

 

Ok I just went out for a drive and I know it was fully warmed up. I got into vtec 4-5 times and then it started the same thing wouldn't allow me to rev past 6000. What could it possibly be???? I have an emanage but the vtec engagement is being bypassed on it. We are running vtec off of the ecu. Would this have an effect on anything????? Thanks in advance

 

Sorry bro i dont know the workings of the profec b-spec, but it sounds like you turned on the rev-limiter or 2step settings?

 

I have the profec in off mode??? Could it be the stock map sensor?? I have a MY 01

 

If its in the "off" mode then what is controlling the boost?

 

The wastegate. 8psi lo boost is at 10psi and hi is at 12 psi

 

Justen, make sure you check all your vacuum lines. I was doing some work today and when I boosted, the WG and bov let off at 7K as if I shifted. I checked, and noticed that I forgot to put the vacuum line for the WG back...

If not, your Map might be acting up. A lot of people notice that the stock one will break up under boost; mine definitely acted that way before I put the GM 3bar on.

 

I'm going to pick up a map sensor now the dealership has one in stock for 69 bucks. Gotta get there before 6pm. I will report back later.

 

cool, good luck
