Stepper Idle Up / Advance not working

So I'm on a recent 5.x code for Megashift and finally got around to hooking up the idle motor, which is driven off the stepper chip via an MSPro. I noticed despite all the criteria being met for the in "D" but stopped to idle up not working. It says that it is for MS2 in tuner studio, so I...

Re: Put Trans in Neutral won't shift till stop

Glad to know I'm not crazy :mrgreen:

I'll update to the latest stable release (prior to going back to the 5.x beta codes) and see if I can get the weird target behavior to come back.

Re: Put Trans in Neutral won't shift till stop

I'll give your two error handling suggestions a try and see how it goes. I was also thinking about going back to the latest 5.X code so I don't have to worry about the flash burn corruption issues as much. Thoughts?

Re: Put Trans in Neutral won't shift till stop

The car has a ratchet shifter for starters, so ending up in neutral can easily be accomplished. In a racing situation, some might prefer to pop trans into neutral, thus letting the engine idle as opposed to either engine braking (ie, shifter in 3rd gear) or the trans shifting to overdrive when you l...

Re: Put Trans in Neutral won't shift till stop

In driving the car to acquire the datalog for this thread, it did something else weird. The "target gear" got stuck and stayed at ZERO, thus the car wouldn't shift. I had to come to a complete stop, but the shifter in neutral and then back to Drive. That "unstuck" the target gear...

Put Trans in Neutral won't shift till stop

If I put the shifter in neutral on my 4L80e, which is the same input pattern as PARK and is setup per the docs.....I can't put the car into any forward gear again until I come to a complete stop. Using the ratchet shifter and going anywhere between 1-4 gears while moving works fine, but if I put it ...

Re: Getting MS3 to read VSS & Gears

Ok, so I drank some coffee and looked into the INI file further.... for the CAN stuff on Megashift it looks like the gear offset is 12 and the VSS offset is 2. (Lance please confirm). What I don't know is the datasize (8bit vs 16bit) and what to set the scaler% to in the speed/gear settings. James h...

Getting MS3 to read VSS & Gears

So MS3 has the ability to poll the can bus for the VSS, but I frankly have NO idea how to set it up and cannot find any documentation anywhere to help.

Burnout Mode Questions

From what I understand in the docs, burnout mode keeps the car from downshifting back to 1st when in D2. While that makes sense, most trans builders in both the GM boxes and the Toyota boxes prefer to see the WOT burnout in 3rd gear as to not roll the sprag. What are your thoughts on this?
