Ecumaster forum

I have a 3sgte (st215) in a 1991 Mr2 with a EMU that I purchased from ATS ...GREAT PEOPLE and GREAT service .... I decided to join the board to ask a few questions and give Scott's inbox a break ( he's been more than helpful thus far)

Issues I am having

How can I LOG BOOST PRESSUre I tried different log options and no luck ... If there is a way ( I'm sure there is ,can it do it in PSI.) or is only MAP (KPA) ?

I'm having a TPS issue it reads voltage fine but every time I cycle my engine ( 24hr sitting and start up again) my TPS value changes ) after I readjust it drives fine . (Throttle cable does not have tension and has a bit of slack

Also on the Bluetooth APP I can ONLY get RPM gauge to work NO other gauges are functionalnon the EMUBT . This might be a common issue and I will continue to search the board for a solution.

Thanks in advance

Boost can be logged in log menú/graph1 and choose boost. Only need make play button and all change la will be saved.
Tps problem can to be that you dont make permanente your changes? When you If modify your map, you have push F2 (make permanent your changes)
Bluethooth Issues: what is your emu version?

I have 3sgte 3 gen

Changes are made permanent. Version of Software is the latest (EMU software), the Android app is the newest on the Google Play store .... Is there a newer beta version ?

On LOG I see options
Boost Target
Boost Correction
Etc etc

But which is actual BOOST manifold pressure ? And is there a PSI option ?

Choose Map in the log thats your mapsensor.
You have to choose EcuMaster serial protocol to run your app.

I'll try the protocol tonight

So switching over to EMU Protocol solved my Bluetooth APP issue thanks ! ...I'm living this unit more and more everyday.

As far as TPS issue is still present. But much better what I did was set the Min. Voltage to a number in between both volt signals I have Ben getting and it eased up a bit . Still have to tweak it ... I'm wondering if I should loosen my TPS sensor and adjust accordingly and calibrate it on the Software .

I also just noticed I am getting KNOCK under partial load/throttle at the 2300 rpm range until 3400. It has been 2 days since I noticed this ..

The knock occurs while cruising and attempting to gain speed barely into boost.
Could be engine noise, not sure how to tune out engine noise and how to tell the difference.
