Ok my update is blown half shaft fixed myself, got tuned by mase ,upgrade map sensor dident work with the greddy emu so 10psi it was, electronic boost gage stoped working .
Got home diff blown as well as the final gear spline ,second hand diff got ,and cusco diff put in setting 1.5 80% done by me.Then bushes on front die, TCT rattal,rear disk buggerd ect ££££$$$$$.
So a couple of questions please.

1 Ive got the greddy boost sensor can i just plug it in? where have you guys mounted it.
2 And what did you use to stop the stock map sensor seeing boost plus do i have to activate anything on the emu.
3 Im persumeing that because im boosting to 10psi iff i rag the car i keep hitting a fuel cut pain in the ass any idears can it be turned off.Is it the stock map sensor f@#king about.
4 Ive got some id 750 injectors to put in due to my 550s ownly being good for 350hp im will ownly be seeing 350whp 14 to 15psi this results in a whole new tune BUGGER !!!!
Thank you for your help guys i will check back as often as i can on 24hour call at the mo Lee.

 

You need a 3 BAR map sensor and a tune for that. Oem map sensor will not run right when seeing boost.
Check out SOS or Hondata plug and play map sensors.

 

I believe the OP's original question is correct if he's using the e-manage. The Greddy Pressure Sensor will plug in to one of the two ports on the EMU. You'll need to "clamp" the OEM map sensor voltage to 2.85 volts in the EMU so that it stops reading above 0psi. Then you'll need to add in the values for the greddy pressure sensor so the EMU will know what pressure it's seeing based on the voltage.

Check this thread for the math on the voltage-pressure relationships:

Connect the Greddy pressure sensor to the vacuum line that runs to the fuel pressure regulator. Leave the OEM map sensor where it is or relocate it to the same place if it's seeing erratic readings. I cut that line in half, installed a "T" and then connected it to the greddy sensor using some more vacuum line from a local auto parts store. There's an OEM bolt nearby that holds an OEM sensor on the side of the cylinder head cover near the oil fill. That bolt is long enough to hold the greddy sensor too if it came with the bracket (that's what I did). Then run the greddy wiring harness from the greddy sensor back through the OEM wire harness grommet (under the clutch fluid reservoir) and into the passenger compartment to connect it to your EMU.

All of the above is per MugenRioS2k's suggestions in other threads. I get tuned Friday so we'll find out how well I followed his instructions.

Yes, I've got pics. No, I can't post them until tonight, sorry!

 

Thank you Torque Obsessed i will read that and try to understand it step by step cheers Lee. ps good luck with the tune.

 

My head hurts already

 

I bought the sensor and never set it up... for some reason my car runs fine without it.

 

Here's a pic of the Greddy Pressure Sensor installed on my car.

 

Yup pretty much where I have mine... it's all plugged up and ready to go. I just haven't changed any settings to have the car run off of it.

 

Cheers for the pic my managment light came on last night shes not happy.

 

Do you mean maintenance light? That is just an oil change interval light. Reset it.
