Having read every line of the Tuning Manuals and scrolled through
every similar problem in this forum and I have finally come to the conclusion
(from a similar posting) that I may have a Firmware corruption in my MicroSquirt.

Problem is: transfered a perfectly good operating system from a MegaSquirt 1.
engine ran a couple of starts.
had problems getting the ignition part of MS to work.
I have a tach signal, spark, pulse injection - but will not fire the
injectors on cranking .

Solution (maybe): how do I reload the current Firmware to my MicroSquirt.

TunerStudio says I have MS vo.999.7 ECU definition MS 11 Rev2.88600

You can't run an MS1 tune on a MicroSquirt, but you can export your VE and spark tables and import them into a MicroSquirt tune.

Have my engine tuned via TunerStudio with a VE table transfered from MegaSquirt 1
Under 'Basic Tables' - VE Table 1 (Map) when I power-up MicroSquirt the cursor will not move
from Bin 1000rpm/100.0 calcMAP KPA. when open up the TPS Throttle.

My understanding is that at this point (above 70%) - the injectors are in 'flood clear' mode.
Hence my injectors won't fire even with a correct Tach signal. Also, I figure that the cursor
should be at 1000rpm/30.0 KPa in the VE table beforeyou start the engine, so you are not anywhere near 'flood clear'.

I have checked out the TPS unit - and it is operating correctly.
The current tune is 'Pure Alpha-N'.

Under 'Other Tables' - Alpha-N MAP Table - the cursor is in Bin 1500rpm/30 tps % and advances
up the table to 100% when the throttle is opened.

I am trying to find what setting I have made in 'Fuel Set-Up' to get me into this situation.

Hey, It did turn out to be Firmware corruption. Downloading the latest code resolved the injector firing problem.

It turned out I was not imagining this problem. Turned out to be corrupted Firmware. Downloading
new code fixed the problem.
