I was driving 2 nights ago when my single turbo rx7 started hiccuping and acting erratically so i turned the key off the attempted to restart. nothing happened.

I looked at my commander to see it reading 2.14 bar with the car not even running!
first thought was to unplug the map sensor and attempt to re start the car- with my GM 2 bar sensor unplugged the FC was still reading 2.14 bar-

Has anyone seen this or have any ideas where the problem might lie?

 

check your grounds!!
try a stock map sesor and see what your reading are then.
good luck!

 

Check your sensor screen and see if the TPS setting are way out also. This will narrow it down to a bad ground or PFC

 

i got my volt meter out and im getting 5 volts from the power side and the signal side which leads me me to think its the PFC - I will try my sensor screen but ive driven the car for 2 weeks since tuning with 0 issues- I think something shorted/fried in the pfc. unfortunately.
