HighRes on MSPNP - anyone?
Is anyone running the HighRes firmware on their MSPNP? If so, did you have to jump through any hoops to get things running nicely?
I'm thinking I'll change to this firmware before I start tuning my fuel map so I don't have to do things twice, but I'd like to know any "interesting" experiences people are having first, if any!
I was thinking the best way to go about it was to use the same values in EasyTherm as the original MSPNP firmware, so changes are kept to a minimum. Hopefully this will let me open the MSPNP MSQ with the rest of the settings intact.
Cheers

Jerry & I spoke about the highrez firmware once 6 months ago and determined that it really isn't necessary for my car and my tune.
I think the easytherm values will be the least of your concerns. You'll need to go page by page and make sure every setting is correct

I only went back to the stock code as it induced a really irritating Missfire, (which I'm convinced is earth related but have never been able to fix).
Ben, I'd advise giving it a try, it doesn't take long and you can load your current MSQ to the code with no issues (that's what I did). I think you'll be impressed with the improvment.

I'm definitely going to give it a shot.

Seems like there was some discussion about that misfire problem in the MS1 development forum over at MSExtra. I got the impression that the problem started in build 10a, but somewhere between there and 10d2 it got fixed. Any idea which build you were using?

my wiring under the footwell is a mess, and my earths are *****, I have a wonky CLT signal from it so i'm 99% sure that's the issue.
I did run fine with it when n/a too.
he car runs fine now, including idle. I'm not unwilling to try, but I don't know if it would be worthwhile...

OK, so the most recent build of HiRes is 10d2, correct? What downsides would there be if I reflashed? I have a non standard 4 bar map sensor. Have the issues with non standard sensors been remedied?
I am not against improvements, but I AM happy with the way the car is now. And I have plenty of grouding between the MS and head.

According to the release notes in the .asm:
Richyvrlimited, I'm still learning the software here. Did you have to make any changes to MegaTune (or the filestructure on the PC in general) or is it as simple as just dumping the binary into the MS and running?

Thanks. I d/l'd the file but haven't opened it or anything.
Next dumb *** question. Say something just isn't right with the new firmware. There's no known reason why I couldn't simply flash my old firmware back in right?
I can give this a shot on Sunday.

You askin' the guy who hasn't even finished his own MS build yet? 
Yeah, from what I gather over at MSExtra.com and from the datasheet for the CPU, doing a firmware reflash cures all ills.

Yes you can just reflash it. I did the standard firmware to MSnS-extra flash on my old MegaSquirt and that required a jumper on the board, but once you are running some variant of the extra code you can flash without it.

I just copied the values from inside matfactor.inc and cltfactor.inc in the MSPNP car folder then punched them into EasyTherm. I have written the new .s19 file, hopefully that is all that needs to be done for the firmware itself. Ben, my MSPNP is running a Map Daddy, I am assuming this is the same as your setup?
Now to set up MegaTune...

had to do a minor amount of tweaking as I found I could run the idle leaner without it stumbling.
similarly I did the reverse when I reverted back to the standard extra code.

Ben, did you end up trying this? I haven't tried it on mine as I have been worried it would run a bit leaner due to the higher resolution and I don't have an LC-1 yet.

No, I did not because someone tried before me with bad results. He had a failure when loading the new firmware, and he was not able to flash the old firmware in without opening the box and installing the boot jumper. I don't want crack open the box and mess up my warranty.
