3 Bar sensor

[Dazzi]

Forgive me for being thick, but where do you plug this sensor into? The inlet manifold, intercooler piping or vacuum line?

Thanks!

[DrNick]

The cable plugs into the option port on the front of the emanage.

The vac port goes into the vac line which supplies your stock MAP sensor - just cut this line and put a T piece in there. Fit the sensor on the firewall near the stock sensor and it will all look neat.

kinda off topic but with a map sensor cant the emanage do speed density and you can chuck the maf on a NA-t car?

[DrNick]

Yes you can simulate a maf signal from the emanage and get rid of the factory air flow meter. Big potential for improvement on US cars which have all the issues with the air flow meter.

Is the map sensor required for us with JDM cars if wanting to run upwards of 20 psi?

[DrNick]

If you have a JDM GTE then you should be fine running 20psi on the stock sensors.

[shaodome]

Do you happen to know what the stock JDM Map caps out at? I mean, I'll be clamping it at 4.3v, which is what 12psi? It only goes to 5v max. thanks for taking the time to answer all my questions Nick. I really appreciate it.

[DrNick]

Hard to say since most of the guys here have some sort of management installed :( Although one of my friends is running just over one bar with completely stock ECU , so I would guess you can clamp it at 16 or 17 psi with no worries. You will need to get rid of the factory boost cut so run datalog mode, drive the car hard and then look at the datalog and see what voltage you hit boost cut. Then you clamp just 0.1v below that.

[shaodome]

I don't know the Boost X Voltage, but I do know the factory ECU cuts at 4.31, so clamp will be set at around 4.29. So from my understanding with the EMU...

Open up the Boost Limmiter Cut setting and just set the clamp voltage I want given the RPM bins. In my case, boost doesn't really shoot up till 3500+ (TTC), so I can leave it as is and then from 3500, just type in 4.29 across up to redline?

With the map clamped, there the EMU doesn't really care about the output to the ECU as it will still receive the voltages ABOVE 4.3 put out by the sensor and I'll be able to tune accordingly?

hi there, is the 4.31v signal coming from your OEM map sensor or the new 3 bar one?

[Mr Ree NZ]

The cable plugs into the option port on the front of the emanage.

The vac port goes into the vac line which supplies your stock MAP sensor - just cut this line and put a T piece in there. Fit the sensor on the firewall near the stock sensor and it will all look neat.

Hi Nik :)

Just a question in regards to the above...what is the reason for leaving the factory map sensor in and connecting them both with a t-piece?

Do you have them both wired up to the ecu too?

I only have the 1jz-gte sensor installed so I guess my question is Am I doing something wrong?

Cheers mate

[DrNick]

Hey Ree. The plus side of leaving the stock MAP sensor is that you dont have to fiddle around with any pass through scaling and you can let the stock ECU work in a completely standard way for your off boost map sections. However your IJ adjustment maps would be mapped for the new map sensor vs rpm. You can make it work perfectly well the way you have done it though, I just like to retain as much stock functionality as possible. For example now my stock ECU is just working normally and I have the emanage applying a 22% correction across the board to scale the injectors down and it all runs like a completely stock setup.

I am using the stock map sensor right now, but the map clamp function of the EMU is NOT functioning.
