Dave, I have looked at your datalog, and loaded your msq on my bench. I see exactly what you do - 2nd, 3rd, 4th, 5th, then 2nd in both manual and auto modes. This is very clearly a code problem (not a configuration, setup, or wiring problem). That's good, as it should narrow down the possibilities. ...

Dave,

Thanks, I will have a look and post back here once I have something for you.

Dave,

That certainly isn't the way it ought to work. Do you happen to have rpm checking turned on? If so, you might turn that off just to see if it makes a difference. In any case, an MSQ and datalog should let us get to the bottom of it fairly quickly.

Jim, I am not 100% sure what you are asking. "Spare port" is a general term we use to mean that an output (and soon some inputs) have functions in addition to their original use. When the output is used for it's original purpose, it is just called by that name. However, when it's function ...

1. VSS- The stock speedometer is cable driven and it has a 4 pole reed switch to convert it into a digital signal so the ECU and TCU can use it . I scoped the signal at the connector for the old tcu and it a 5 volt signal . So will I be fine if I use the circuit described for VSS / VR1 in the 4l60e...

Something that I did notice, and maybe it just has to do with definitions, is under Hardware/Transmission Type, no listing for the AA80E. Don't know if that is important. Jim, We don't have the settings and build guide for an AA80E yet (since you are the first to do one). Once we have a 'known good...

Jim, Attached is a preliminary version of 5.202ti test code (and associated INI). IT HAS NOT BEEN TESTED. I am posting it for you to have a look at while I do the testing. This code enables spare ports 4 and 5 as outputs. Spare port 4 is on pin PT6 (normally the Paddle Up input). You enable spare po...

JIm,

We really should put in parameters to allow the user to specify which shift lever positions are valid (PNR+8th, for example, with the rest ignored). That may not make it into the upcoming code, but I will add it to my list.

Lance.

Jim, Grounding the inputs sends them low, not high, but otherwise what you say is correct. Two things, though: 1) With the current code, PNR *must* be selected by the shifter mechanically. Most transmissions (all that am aware of) work this way; it's a safety and limp-home feature. The code could be...

Does anyone use a debugger with this system? Bill, I don't use the debugger (though I have P&E cables, etc.). I use a stim and actual inputs and outputs (plus various user input parameters for input and output channels to test internal values, states, and register contents; plus a scope of cour...
