You only need the boot jumper if its running the standard megasquirt code (not the "extra" code that you already have loaded). All you have to do is connect with the serial cable and run the "download-firmware.bat" program and follow the instructions.
Depending on what code you have loaded currently you might have to verify your settings when you move to hr_10d2.
I have the code listed in the sticky in this section....
The 029V code is what I have. So basically I disconnect my coil, turn on laptop with serial cable connected to unit and run the download-firmware.bat program from the code you have in here. Wasnt there a specific folder you had to have the code dumped in? I thought the guy that did mine went through another way of upgrading my firmware. I will probably bring the car to the tuning place and have them fool with tuning it once the update is done. That way in case there is anything that has to be modified that I dont have written down they can fix it there.
I was under the impression that MSII didn't have wasted spark/dual vb921 capability.
So I'm to understand that it does with MSII-Extra?
Cause if that's the case, I won't even bother trying to get this thing running on the MSI unit.

Gosh if I wasnt so close to my tune date I would do it. On the other hand it will be fully tuned....then I will upgrade to the new stuff and go back to pay $150 for a retune.
Well its set for Dec 8th, but I can cancel if I needed to. I dont have the correct tools update the firmware correctly. Meaning checking voltages, etc like it should be. I should be ok with the flash, but I would rather have my friend do the firmware flash for me since he has all the necessary tools. He is working on his car at the moment. I just am getting a little tired of my car running higher egt's at higher speeds. I dont have a way of checking for knock yet(knocksense not installed) so dont want to turn up the timing too much. Having 42 degrees of timing while cruising seems high, but people tell me to keep going up more....just a little too risky for me. I guess I am just being over precautious is all.

K I am pretty sure that I am going to just cancel the dyno tune and upgrade. Since I have the v3.0 board with the ms1 extra I am assuming all I need to do is upgrade my chip for $20 or whatever it costs and then upload the new firmware? I will take screen shots of everything I have set in the current setup and export my tables to make it an easier transfer.
MS2 chip: This is an $85 processor upgrade for your megasquirt. You unplug the MS1 processor and plug in a daughter board that contains the new MS2 chip (along with other stuff like a 4-wire IAC motor controler, CAN interface, etc). This is a totally different 16 bit processor (as opposed to the 8-bit MS1 processor). The code this thing runs is ms2extra. The developers have written a decoder for the SRT-4 but nobody has tried it yet (as far as I know).
Also there is:
MS1/extra high-res version. This code simply installs on your current MS1 processor with no changes other changes (other than tuning). It gives you higher injector pulse width resolution but you lose the ability to control low impedance injectors (so you have to use a injector resitor box or the "pwm board").

I hope that clears it up for you.
Thanks for clearing it up. I mainly want to upgrade to have the 16x16 feature so the tune can be more precise instead of how it is now. I am assuming with all the benefits that come with the MS2 its better to just pay the $85 and go that route. With the MS2 as you said comes with a new board with the chip already in it so all I have to do is unplug the MS1 Processor and plug this in. The additional things such as CAN(dont know what that is), and the 4-wire IAC motor controller I am assuming are things that "need" to be done as well with the MS2 upgrade correct? I dont really like my car being down, but its been down for 6 months straight before waiting for parts. So since I have another car I figure why not upgrade...get what "needs" to be installed so I can get it running again and I will be happy. As far as tuning it to make it run correctly and having a good tune I will just pay for it to be dyno tuned. I just want to make sure when I get this new board that I dont miss anything in addition to the board with the ms2 processor so nothing gets fried or freaks out. Since I got my unit from RS should I just build a whole new one or is it easy to swap this stuff out? I am guessing this ruins my warrenty(not sure if i even got one) with RS, but whatever. My main concern is just making sure its done right the first time....would hate to ruin it ya know.
Sounds good to me. Just know that the NGC code for the SRT-4 hasn't been thoroughly tested yet. You'll be the beta tester. So I wouldn't be surprised if you find bugs. Then again, you may not
Also, I don't know what all is done to the RS boards. You'll probably want to read up on how to do the MS2 processor upgrade and study your hardware configuration.

wow information overload for sure...I just read it all. Man this is going to be a little tough Its pretty involved due to having the v3 board and what needs to be done to make it work correctly.

MS2/Extra has had multiple spark outputs for quite a while now.
