Pretty sure its 96 in decimal. It has to match to the 0-96 "psi" of the force motor table.

Nice changes. Did the line pressure slider get changed to command 0-96 as it is moved from 0 to 100%?

Remember, all widebands read lambda. To give an AFR number, the lambda value is just converted to AFR using a math formula. So, it doesn't really matter what "ideal" or lambda =1 AFR is picked as...

You can say the 0-96 "pressure" signal works inverted, but that would be wrong. The 0-96 "pressure" signal is directly related to line pressure. The force motor table lookup converts the "pressure"...

The values in the pressure tables are not the line pressure in psi. They are just values from 0-96 which represent the minimum to maximum possible line pressure. All of the various applicable "psi"...

You got it, it uses the 3-D force motor current table to set the current and then the transmission runs at whatever pressure that current produces. So it's a very good command to see the pressure...

The force motor current tables are in mV, so 3 decimal places are needed to display the commanded and actual current values as accurately as the table allows them to be set.

I was double checking...

I tested the line pressure. It sets the "current torque signal pressure" which is an internal "pressure" signal that goes from 0 to 96 with 0 being the lowest transmission line pressure and 96 being...

LOL, I was going to get back to you on what 0-255 meant force current wise, but you jumped the gun and made a new scale. I do appreciate the addition and I will get to testing it soon. I think the...

I'll be trying it out on the weekend.

As long as you don't lock it out using the C15 P/N input because I didn't connect it. I think the Tech testing was supposed to be done in park.

The problem with doing it when driving would be...

I've seen GM documents for testing line pressure that say to use the TECH and change the current in 0.1A steps. So, it'd be interesting to see if this is current or % duty cycle. If it's current then...

I looked again and it's exactly half. Just take the .zip off.

The VSS2 road speed a little further down the table is correct.

On another note, the filtered VSS was around 1/2 of my actual speed on the transmission tab.

Can we control or test the line pressure or force motor current on an automatic?

I got a little FT232RL adapter and it works OK. A couple of times about 3-6 errors would happen at once but overall it still worked fine. It seems QT doesn't handle my other adapter correctly even...

The timing retard is a dedicated PWM signal between the ABS and PCM. The speed and accuracy of the timing cut signal goes beyond what the ALDL can accomplish.

The ALDL stuff you see would be to...

I just tried BMJT and it was no better.

The Check VIN info from CATS says 95 T/A, but I thought the VIN was not part of the bin file??? The PCM came from a 94 M6 T/A and I switched bins to a 95 A4 bin. I'm not sure where I got the bin...

I tried the beta and here is a verbose log. It's like the interface isn't there, except it is and it does work. It did switch from the no echo to echo corrupt as the error message.

As I originally posted CATS and Tunerpro work. I've flashed the PCM dozens of times with the interface. I think its a MAX232 device but I've had it so long I hardly remember. Its a board and parts I...

This is what I get. It's sending silence requests but there are no other modules on the serial bus to respond to them.

An Express card then. PCIe expansion slot on a laptop.

It's a stand alone LT1 install. There are no other modules to interfere with the communications.

I'm a little disappointed. I finally had my car out today and but I just get errors connecting. Mostly no echo and a few bad response errors. It shows the PCIe serial card I'm using so it seems to...

It's not just the same points, but the curve as well. Otherwise, what basically happens is that when the normal downshift is lower between the 2 tables then you can get this downshift-upshift thing...
