Firmware Update Issue

[craigkenyon]

MS II v3.57 originally loaded with MS2/Extra 2.1.0 Updated firmware from that to 3.3.3 . Loaded msq file. Car ran great before. Now, hard to start, won't idle, holding the throttle open a set amount (thinking the IACV needs tweaking) the motor hunts up and down over 1000 RPM. Any ideas?

That's a big jump in firmware, did you read the release notes to see if anything significant changed?

I remember reading in the release notes that IACV settings need to be re-done at the very least.
There were a number of things to verify after upgrading.

Have a read of the txt file included with your firmware.

When I loaded it, I went through all the load notes and read me texts and checked off each item. I then loaded each page item manually but imported the VE, AFR and IGN tables. Didn't run. Imported the old tune and checked all items again. No luck. Then I disconnected the IACV and held the throttle plate open in a fixed position, still had problems. Now, I would like to reflash the old firmware, and reload the old tune to see if I have some other issue that just happened to happen at the same time.

Does anyone have the files (and loader) to load firmware MS2 Extra 2.1.0?

Disregard post, got the firmware. DOH! cross fingers and see what happens now.
