I just installed a jet V-Force PCM on my 97 Accord LX. (SOHC, F22B2, Obd2)
This thing is awesome. The power it gives is great.
The only problem is when i rev at like 5k rpm's it throws a cel
PO 107 (Map Boro Circuit Low Input). When the cel is on the engine
boggs down and sometimes backfires. I'm not sure what to do.
I called Jet's tech support, they said instead of jumping the radio fuse for power
try using the dome light. That didnt work. They also said to try wiring the power
direct to the battery. I have not tried that yet, but i dont see how that would
correct my problem.

If anyone can help out that would be awesome.
These damn obd2 engines are a pain in the ass!

 

I'm going to say bad ground or bad unit, you have to figure, the box is manipulating the MAP voltage just like an AFC. And you just coincidentally happen to start throwing MAP voltage out of range codes...... riiight.

remove the Jet PCM and see if the problem is still there. your MAP sensor may have coincidentally died. not likely, but definately a possibility.

 

Im sure that the PCM is making the cel come on.
I wonder if this thing can even work correctly with an 0bd2 car?
I will double check the ground wire.
Im making a grounding kit this weekend, maybe that will help.

 

is that the code for the map sensor, or the barometric pressure sensor? cuz i know on the obd1s, when u adjust the airflow too far out of range, it will throw the baro code cuz theres too big of a difference between with the map is reading and the baro sensor in the ecu, or something along the lines of that.
