if i get a gm 3 bar map sensor how do i wire it in and will i have any reliability problems with it? rough idle etc...?

what management are you using? if set up properly it will run fine.

uberdata.

i dont have one yet, but i'm getting my engine built and plan on maxing out the stock map so i want a 3 bar to put on. i want to know how to wire it up. and i have read that idling is suffered with that map sensor.

Uber + 3bar = trouble right now.

oh, you cant use uberdata with a 3 bar? you have to use the stock map sensor? therefor i'll be limited to 11psi of boost?

I haven't followed uber for a while now, followed both uber and crome and eventually tuned my car using crome. I'm running stock MAP right now, but bought a motorolla 2.5 bar MAP that I need to install. If you plan on running under 21 pounds (somewhere around that), you might want to look into the motorolla as it's only about $15 or so.

FYI, 3 bar install: http://hondata.com/tech3barmap.html

thanks for the info, where can i get the motorolla map sensor at?

digikey.com part# MPX4250AP-ND. I lied though, they're $18. Also, if your order is under $25, they tack on $5 (maybe you can buy some more chipping supplies if you're chipping your own ECU). They're shipping is affordable though. Go for the usps priority and it will only be $3.85 shipping. I <3 digikey (how gay)

If you want to know the wiring for a GM 3 Bar Map (can run up to 29 PSI)

BTW this is for an OBD1 Wiring Harness
A- goes to the Green and White wire which is ground
B- goes to the white with a yellow stripe which is the map signal
C- goes to the yellow with a white stripe which is the 5V Power

BTW this is for an OBD2 Wiring Harness
A- goes to the Green and White wire which is ground
B- goes to the red with a green stripe which is the map signal
C- goes to the yellow with a red stripe which is the 5V Power

GM 3 BAR MAP will work with Hondata but you need to have your datalogger set to GM 3 BAR MAP Voltage because the GM sensor runs on a different voltage than the stock Honda sensor. What I did with mine since I do not yet have datalogging is I grafted in the GM 3 BAR MAP onto my stock harness and then I will switch which MAP is plugged in when I go to get my motor tuned. This way I can run my stock one for now and then just unplug it and plug in the 3 bar when I go to get it tuned. Also if I ever want to sell the car but keep my 3 bar and Hondata I can just plug in the old MAP sensor

I haven't had any problems with 3bars with uber, but I am personally going to run the 2.5 bar motorolla Map.
