Default wiring questions

Well, i used to be boosted now im switching back to all motor....

right now i have the 3bar gm map sensor, will that be fine or should i switch back to the stock one?

currently i dont have the vtec pressure switch wired up, would i be ok to let it ride like that or would it be a good thing for me to wire it up?

I had 2 wires tapped into the jumper harness, one was for the widband (was told so the comp can learn and adjust off of the widband) and one was for the boost solenoid that i had. Can i leave those 2 wires as is or do i have to hook em back up to where they were in the jumper harness?

Your answers depend on what pcm/ecu/tuning software you intend to run.

also i drove my boosted setup for about a year and never had a problem with the vtec pressure switch not being hooked up ...... pretty sure it just wont let vtec come in if oil pressure is too low...

I would switch back to a stock sensor, it will be much more accurate for your application.

..i was worried about it being weird to tune on since im not boosted anymore...

cool no pressure switch ..just check my oil often lol

anyone have any input on the boost solenoid and wideband wire?

i could be wrong but the original wire spot in the jumper harness (that is used for the wideband) is the stock o2 wire ...which if thats true, i wouldnt need to hook it back up....i think? lol

but im pretty sure for the boost solenoid .. hondata uses A11, the EGR solenoid wire to send a PWM signal to the boost solenoid...and if thats the case then i wouldnt have to worry about wiring it back up as well

can anyone back me up? looks like i dont have to reconnect those wires..dont worry about pressure switch and run stock map sensor?
