MAP Sensor Help
this situation is really starting to **** me off. i keep blowing the MAP sensor on my civic.
im running a B18C JDM GSR
fully rebuilt
Crower Rods
Aris 10:1 Pistons
330 Greddy injectors
Apexi Boost Controller
Apexi VAFC
Missing Link
All the AEM Fuel Stuff there is
Holly intake fuel pump
Drag 3 Turbo kit
stage three port and polished head
pro spec valves
pro spec springs
prospec retainers
and a whole bunch of other stuff that shouldnt matter for this situation.
im am still running the p72 ecu and i keep blowing the MAP. the car runs great just driving around town and not taking it over 6000 rpm. when i go to rip on it i blow the map, even with the missing link, at around 6500 rpm. i tried to tune it on the dyno but i couldnt get it to go over 6000 with out hiting the MAP. i was having problems with the turbontics waste gate and it spike my boost between 15 and 20 lbs. i ordered a tial waste gate to fix the prob cause everyone i talk to says the drag kit waste gates do that. it should be hear this weekend. the guys at the shop tell me this should fix the MAP problem but i dont see how. any one else have any ideas on what to do here? i am trying to get around from having to bye a 3 bar MAP from Hondata.
thanks

Re: MAP Sensor Help (btole)
What boost are you running? And to verify, you have *no* boost spikes now?
If you're blowing the MAP diaphragm, you have to be exceeding 12-14 psi... some people here do that recreationally, but it doesn't happen with that much regularity. I think you're having a problem with your missing link, it is NOT bleeding boost.
