minimum pressure of 40%

Am curious if there is a way to command something lower than 40%? According to the documentation, it looks like it is hard coded as 40%. I installed a shift kit in my transmission years ago. Part of that "kit" was to tweak the adjustment screw on the PC solenoid a quarter turn to increase ...

Re: Trouble getting CAN data from MS3 to MShift

I re-loaded 4.136 code, and that solved it. Something must've been corrupted.
I tried loading the lastest code 4.137 and it works also.

Trouble getting CAN data from MS3 to MShift

Am having trouble getting data (tach, load) from MS3 to MShift. Am running MS3Pro 1.2.4 and MShift 4.136. I've researched the how-to's best I can, setting up the Outpc etc. Attached is a screen shot of my setup. I have also included the MShift ini file. I am running MShift as CAN pass through. Thank...

Re: Line Pressure dead...

Hey Lance, Well, this tip was the secret... >>To use the 2-pt calcs, you need to set that up under 'Standard Inputs/Outputs Configuration -> Line Pressure Input -> Use 2-Point Calcs'. After I did that, I could get a nice sweep from 0 to 5 V. And then using that menu within TS, was able to get the 2-...

Re: Line Pressure dead...

Lance, I made a video tonight and posted it on youtube to show you how this linepressure is responding. For this demo, I replaced the pressure sensor with a 0-5 volt pot, and used it to drive both Aux_volts and linepressure inputs for comparison purposes. Below are the cal values used in the ini fil...

Re: Line Pressure dead...

Lance, I didn't get to spend much time in the garage tonight. Am still confused on some of this. I appreciate your patience with this, as it is probably something I'm missing. In your last email you said: >>The limits in the present code are that a 0-5V signal maps into 0 to 1023 ADC counts and >>BT...

Re: Line Pressure dead...

With regard to the 0.5 volt offset for the sensor you guys recommend, hopefully that is not hard coded. If I had access to the raw ADC counts, I think I could make this work. The sensor I'm using is the A/C pressure sensor off of the Gen F-bodies. I've used it before on a MicroSquirt project to meas...

Re: Line Pressure dead...

I hooked up a 0-5V pressure sensor I'll be using and attempted a cal tonight but was getting some weird results. On the Line input there appears to be a 0.5V offset in the code. When actual sensor input voltage reads 0.51 volts, the Line display in TS reads 0.01 psi. When actual sensor input voltage...

Re: Line Pressure dead...

Just tested 4.136 for line pressure, and it works, i.e. I got a response.

0V = output of 2.
5V = a value of 10.

So on to calibrating these pressure sensors.

Thanks Lance.

Re: Line Pressure dead...

Am seeing the same results as Tobmag during my bench testing this weekend. 4.135 code.
