Car won't start (no fuel?)
After work I started the car, let it idle for a couple minutes then drove into the shop. I shut it off, bled the brakes like I had planned. Went to start the car and leave, and it just cranks and cranks.
- Plugs are clean
- All fuses are ok
- Fuel pump is running
- timing jumps around when cranking, so it must have spark
- Injector duty cycle, etc stay at zero.
Seems to me like the injectors refuse to work. Any ideas?

Check the connection to the CAS?

Post log and MSQ?
The injectors are powered off the same white/red wire (from the INJ fuse via the main relay) as the ECU itself, so if the MS is on, you've got power to the injectors. Besides, if the MS is indicating zero duty cycle, that more or less rules out a fault with the injectors themselves, or the supply to them. (MT would show you injector duty cycle even with the injectors unplugged.)
Do you get an RPM indication in MegaTune while cranking?
Is it possible that the TPS signal is stuck high, initiating flood-clear mode?

You mean that on the MegaTune screen, you typically see no RPM indication even when the engine is running?
Uhm...
(never seen anything like this before...)
Is MegaTune set to "Offline" by any chance? (Under File -> Offline)

Try something: *not responsible for damage, or any reflashing you may have to do
Check your project folder, and see if you have a file called msns_extra.ini.
I deleted this in both the MS directory, and my project folder, and all my problems magically went away.
EDIT: This is assuming the car ran without RPM on your GUI gauge beforehand.
If Megatune tach was there before, and is no longer, then it's a different situation.
Have you done any succesful datalogging/VE analysis?

Was thinking it might be too rich. Mine wouldn't idle at all after I swapped injectors.
It's starting to sound like you're just not getting rpm signal from the CAS, but if you've NEVER had the tach in MT working, I would run through the Braineack install directions again.
I had a lot of problems (OS related) where I would connect one time, and the car would run great, then connect again, and it would burn some values that were different, and run like crap. This was mainly due to EasyTherm not running on mine, so I had to flash it with one laptop, and tried tuning with another.

- CAS : Changed
- Coils : Changed
- Ignitor: Changed
Still won't start. My wiring job on the new CAS connector is still all ok. Thinking something went goofy in the MS somewhere. Unless anyone has any better ideas.
Anyone have a 1.6 map, using a 2560 and RX7 460's they don't mind sharing?
Edit: I'm going to back away for now and any other suggestions I will make a list and try again on Monday.
