It ran smoothly, but had the hp of a freakin pissant...

EDIS defaults to 10° timing. It takes about 400rpms before the VR sensor comes on line and the computer can control timing. When running the computer will tell the EDIS module where to set timing. If the signal is lost then you get 10° fixed timing. It's a failsafe. What I don't know is if I can control timing under 400rpm. Since the starter turns slower than 400rpms I don't know if I can do a start retard to ease starting.
I don't plan on running the truck with a fixed timing and I know that 10° is the standard initial timing.
Anyway... In other news I've made some more progress on my Arduino gauge display. I have everything nicely in their own functions. I can select between them, mostly... I do have to do some debounce work as my crude switch (two wires touched together) is noisy... I can do alarms and even change the display text at the same time. Got to get a real switch....

You can, I just have to play around with it. I added a simple delay which helped but I'm sure that touching to wires together is going to give me the noisiest signal I can get. So I'm going to get a real switch before I do more...
There is a debounce function and there are also ways to do it via a hardware circuit. LOTS of debounce options.

Yup... And the cool thing is that I don't need an analog input. Although, presently the LCD is using one of the two interrupt pins. So I'm limited to one interrupt at the moment, but I'm sure I can switch the pins for the LCD.

You might be able to do it like Chrysler did with the lean burn engines, two triggers, one at say 2-4º retarded and the other at the normal location and have a way to use the retarded trigger cranking and normal once the starter is released.

Couldn't find the switch I wanted at Radio Shack without buying the $99 electronics starter kit... So I ordered some online for $2.50 for a 10 pack...
I'm busy now reading up on the MegaShift progress and the ability to link the trans controller via the CAN bus to the ECM... Remember what I said about NOT wanting computers linked and dependent on each other? Yeah... See, I'm a hypocrite...
Lets see how many more of my "rules" I break before the truck's on the road...

Nah... I'm not going to worry about it... Seems to be the simpler solution...

You can run Alpha-N with just vss and tps. The more I look at it the Baumann controller and probably others just turn it into a fancy AOD.
Running MegaShift I get to actually do load based calculations for line pressure as well as being able to do things like spark retard on shifts.
An example... Going up a slight grade with the throttle steady. With the MS it will see the load changing due to the changing MAP signal. No MAP signal with the Baumann setup. It will have to figure it out via the vss. If I can unlock the converter as a first step based on load change then the MS wins hands down... I don't know if I can do that yet but I can't really do that with the Baumann system...
I don't want to badmouth the Baumann system (USShift.com) I think it's great. Given where I'm at with MegaSquirt I might as well go all in with an integrated system.
I draw the line at integrating a body control module...

Damn, you don't want a little voice telling you "your door is ajar", "you left your lights on", "your key is in the ignition" or anything else.
I can't say that I blame you. I have seen some really weird problems related to a BCM.

Like the lights coming on at random times and running the battery completely down. We'd owned the Murano 36 hours when that happened. No one in the whole world had reported exactly that problem, but some had reported similar problems and the culprit was the BCM in those cases. Our dealership got the last BCM in stock in this half of the US - I wonder why. With the module replaced it hasn't happened again in 18 months - but that doesn't mean it won't.

Ahhh no like talke box???? I have it on my 85 Plymouth Caravelle(from a 86 new yorker) I am currently rewiring the car with a 90 Lebaron Trip Computer, ECU/BCM along with the 86 New Yorker EVA. I did think about installing a EVA in my truck but decided to keep Ford and Chrysler in proper vehicles.
Now if I can get a trip computer in my pickup, that will happen. But Ford did not have many options for a Trip Computer. I did try a mids 80's LTD or equ trip computer in my 89 F250. It did not work as the truck ECU did not send data out like the car ECU.
