UpRev Logging Parameters

kromberg · 03-06-2021, 04:25 PM

For the life of me I can not find the paramaters for Throttle Position and Manifold Pressure. For throttle position I see 'ACCEL PED POS 1 (V-Accel)' and 'THROTTLE SENSOR 1-B1 (V)'. I have no idea what units the ACCEL parameter is in and the 'THROTTLE SENSOR' looks to be in volts. Is there not a throttle percentage parameter? For manifold pressure I see 'MAP SENSOR (mV)', but that is in volts and it is always 0.

I have no experience with UpRev but many programs will allow you to read the data from a PID (https://en.wikipedia.org/wiki/OBD-II_PIDs) and massage it to get whatever units you prefer.

If my memory serves me correctly....the ACCEL PED POS sensors are the sensors in yoru gas pedal inside the car and THROTTLE SENSOR is the throttle position sensors in your throttle bodies. For Manifold Pressure, I will look in the morning as I need to do a cold start log anyway and see what I can find for pressure. Seems strange that your MAP Sensor would not be reading any mV but let me compare to mine as well.

I will look around the logging screen again, but I dont seeing anything like that. Unfortunately UpRev's doc is less than stellar.

I just looked at my UpRev and for throttle position you will want your Throttle Sensor; this is your throttle position sensor and there are two sensors per throttle body. For manifold absolute pressure I see two options in UpRev; Manifold Absolute Pressure and Manifold Absolute Pressure Sensor Voltage. When I data log both these parameters I get 0.00mV on Manifold Absolute Pressure and it does not change from even when I rev the engine (exactly what you stated in your post). However the Manifold Absolute Pressure Sensor Voltage I do get a voltage reading that changes as you vary the RPM although I don't have much faith in the actual voltage reading as I see a range 200v at idle down to 80v at some other higher RPM however seems to show that the sensor is reading. I don't see any other way in UpRev to measure the actual manifold pressure but maybe there is a conversion from the voltage reading on the sensor to pressure.

Thanks for the info as it kinda confirms what I am seeing. I am kinda surprised UpRev cant do the conversion from mv to percentage. Its kinda simple, but now just another step I will have to do.

For gear position, are you seeing it change? No matter what gear it is in, it always reports 0. If the dash can display the current gear, the data has to be broadcasted. Hopefully this is not another thing UpRev dropped the ball with. I am also thinking I should have gone with EcuTek....

Have never actually tried to log the gear position. I have heard from a few different tuners now that EcuTek has more abilities that UpRev.

If you are tuning it yourself, then Uprev is you only option. I want to say gear position is only on automatics. I believe i read that somewhere. Lame it doesn’t work with manual. I tried loggin vehicle speed and rpm and doing a conversion. The data looked a little weird but I didn’t spend too much time looking into it.

It does have gear ratio, so I think with it and RPM you can figure out what gear it is in. The AEM Infinity does that for a lot of tables related to gear position. Its not too bad of a calculation, but a shame UpRev could not have done it and everyone could benefit from it.
