Engine Can't star after aupload to 1.5.1 beta firmware

[montelibre]

Hi.
I was running my V8 jeep with 1.4.1 firmware and I was trying to update it to 1.5.1 beta, but the engine couldn't start with this firmware.
So, I went back to the 1.4.1 firmware again, but now I can't start the engine.

I have attached two data logs.

Thanks in advance.

141 firmware no start 2017-04-29_12_modified.msl

151 beta firmware no start 2017-04-29_12_modified_modified.msl

Post the MSQ, too. I assume it is the same for both logs. Why is the TPS so noisy, and are you cranking with the throttle being held open, or is the TPS not calibrated?

I realized that when the firmware was updated the tune was different and many features have been changed.
So, I load one of my tunes and now the jeep runs nicely.

I have updated it to 1.5.1beta firmware and for now, it's ok. The idle control works much better than before for my jeep.

I don't know why the Tps signal is so high. Usually, the Tps signal changes a lot, sometimes more than 4%. I have changed the TPS for a new one and the noise seems to be the same.

So, you used the same old tune, but loaded it again with the new firmware in place? I'm real interested, since I haven't upgraded my FW yet...

Yes, I loaded the old tune.

First, it made an error, I couldn't remember exactly but I ignored it and the tune works fine.
