Ok I'm working on it right now and here's what i've discovered. the map sensor wiring harness comes straight from the ecu, since this used to be a firewall mounted unit (93 del sol S or d15b7). I hood the DVOM ground to the ground post on my battery, I rung the wires out and the green wire def. has continuity, then there's a white wire, and a yellow wire with a green stripe, one of which has 5.04 volts with the key on, the other has 4.90 volts with the key on, and the green is obiously the ground. I've tried hooking these wires up every way possible and every single time I get 2500mbar or 21-22psi in crome's datalogging, i'm getting even more confused maybe the sensor is bad?

Well...if you have hooked it up a number of different ways...at this point I wouldn't doubt if the sensor is toast.

Without the sensor connected and the KOEO, one wire should be continuous to ground, one wire should be 5 volts, and the other is the signal wire.

I dont really care about the sensor I have a coupple more laying around.

I put the stock sensor back on and it read 998mbar, started it up and drove it for awhile with no problems, need some serious tuning after those 1000cc injectors but other than that it all seemed good.

I still dont understand why i'm getting almolst 5 volts on two of the wires going to the map sensor, the other is the ground, i'll try another sensor and see what's up. Man I feel like a dumbass. Thanks for all the help so far, it must get quite frusterating for you having people ---- up simple little ----,lol.

These threads are tame...you should see the emails I get on a daily basis and the phone calls...OMG, the phone calls. I should start smoking pot...

Well thank you for the help, most people would skim over the thread and say ---- you. I'll remember it next time it comes to making EMS purchases.
