Fred,
I'm sorry, but I don't know what you mean by "start working from the first principles".

Fred, New day, new attempt. I'm not an electronics engineer, nor an electronics technician. I have no formal training in the field. I am self taught. The information I have is that if a resistor is connected to ground it can be considered a pull down resistor. If it connected to a power supply it ca...

Ah yes. That's what I am attempting to do but I seem to be having difficulty getting clarification on some of the connections.

So, are you going to answer my questions or are we just going to do some silly sparring?

"Pxx" means nothing to anyone?? I'm following the Jaguar schematic. Pxx denotes conn-1, a single pin connector. I can't seem to find any direct reference, but from examining the PCB file and the board itself it looks to me like P32 is labled "ign-12v" on the silk screen. Sorry fo...

Andy,
On your schematic 12vdc-switched-outputs connects to 12v-sw2 and P32. What do you want P32 connected to?

Fred
Just to confirm you want me to use RPM0 for trigger input. Delete R22, R23 and R83.

Pishta, I'm not sure what you mean by "port over". As I mentioned, I have what I call my "superstim". I built it to test all the standard MS1 I/Os, the extra stuff I've added as well as my transmission controller. For ignition trigger I just used a 555 timer for a square wave 12 ...

Fred, OK. I'll wire the pin outs as per Andy's post on the subject and wait for some suitable firm ware to load. When I have that I'll connect to the superstim and play with it and get to know EMS Studio. If you give me a link to the source code that the .s19 is derived from I'll study that and see ...

Fred, I thought that I had made my "expectations" clear from the beginning. Initially I would like to have Jaguar and Free EMS a direct replacement for the MS V2.2 board running a modified MS1 Extra code on my daily driver '95 Ford E-150 I6. TFI ignition, alternate bank fired. Once I have ...

SUCCESS! ! ! You guys walk on water! Andy, I followed your instructions. Things went like clock work. Mike, EMS Studio connects right away, interrogation is successful in ~ 5 seconds. Andy again, How does my proposed pin out look? I'm looking forward to downloading some firmware (hint Fred), connect...
