Beta testing

Post by jsmcortina »

Before you get too excited, we aren't there just yet, but I thought I'd post some info about how that process will work.

Presently Ken and I are hard at work on the firmware for the MS3 to get it ready for beta testing.

I have the "monitor" code done. This is the code that runs when the MS3 is powered up before the main fuel injection code runs and it also handles loading new code. The monitor is installed during manufacture and cannot (easily) be upgraded in the field. So it needs extensive testing before we can release any boards. If a problem was found later it would be troublesome for all involved.

The main application is already at the state where it has run my V8 engine with true coil on plug and the eight injectors. (You may have seen my video at the Megameet.)

In the next few weeks Ken and I will be installing the MS3s on our own cars and driving them about to confirm that there are no hidden problems in the code before we unleash it on anyone else.

Due to the cost of the hardware, it will be a select beta testing group. Previous beta tests of Megasquirt hardware have been let down by the testers not actually testing fully. We want to do better than that with MS3 and here are some of the selection criteria we'll be using.

- have a car (or bike) that can have MS3 installed and actually driven within a few weeks.
- have a demonstrated track record of fault finding, bug reporting, feedback etc. on the Megasquirt forums.
- have time to complete the testing
- cover the range of applications we need to test

I have my V8 COP install that will use the MS3X expansion board, but that car isn't really driveable yet.
My other car that can be driven runs V8 wasted spark in "upgrade mode" using bank fire injection.
We already know to some rotary installs that we can test on.

EDIS is a little less interesting as it cannot support sequential as-is, but one install might be useful to confirm that it still works.

With the MS3X board we will be wanting testers for all the "bells and whistles."

We'll also want testers from MS2 and MS2/Extra backgrounds, as one task we would like to complete is making a way to smoothly upgrade old tuning settings (MSQs) into MS3.

The better and more intense the beta testing, the sooner we can make hardware generally available.

Drop me a PM if interested and please don't get mad if you aren't selected!

regards

James

At first I though I should apply for beta testing... but then I thought about my non can MSII beta processor, which has the faulty fuel pump circuit from the initial beta testing of MSII. You never know what you will end up with, when it comes to beta hardware.

If you guy's end up short on testers for 4cyl COP, or wasted spark, using dual wheel non missing tooth setup, boost control, electric fan, tacho, and i'am already running Jean's alpha seq code, let me know. Otherwise I'll wait.

I put my MS2 beta to good use as part of my MS3 prototype by removing the C32 chip and connecting it to the XEP100 demo board.

On the MS3 hardware, we believe that all port pins are working as they should, USB works, stepper works on the bench and I'm working with the SDcard right now. We've had two cars running with it at the MegaMeet too.

Yeah, we've already pretty thoroughly tested the I/O and have not really found those kinds of hardware problems.

James,

I'm willing to Beta test, but I currently have only limited options I could test on the car that I can dedicate to the cause. I'll shoot you a short PM in case you guys want to make use of me for that.

I'm not sure what all you want tested but I had the red metalflake Conquest at the megameet. Running G54B with a MS1 v3.0, distrubtor less. I would be happy to drive up from Tampa for the upgrade. I have the manager of the local speed shop (and racer) that is interested in helping too. I know you took pics of the engine bay. If you need more info let me know. I intend to upgrade as soon as they are available in either case.

Would you guys be willing to support this in the monitor code:

http://www.msefi.com/viewtopic.php?f=69&t=34047

Essentially it allows you to "set" the boot jumper through the serial cable. It turned out to be a very handy bug as I don't have to access the MS which is all the way on the other side of the bus. I'm not sure if this is an easy thing or not, but I figured it was worth mentioning since you're working on them monitor code.

Thanks,
Mike

I just read my other post in that there were problems caused by this, so I guess we can forgo this request.

Is there even going to be a B&G alternative or is it just going to be a newer version of the extra code?

Thanks,
Mike

It will be the extra code + everything needed to support the new hardware and sequential and some of the B&G code merged back in (mainly x-tau for those moving over from the standard code so they won't have to retune EAE). 1.0 will essentially be just what I said. 2.0 will rework timing of injection and ignition into using an angle-clock method of scheduling and will likely incorporate more of the model-based changes that Bruce and Al are working on at the moment in addition to supporting user-requests where they make sense. I am also planning a rotary mode for up to 4 rotors.

Jumperless reflash is supported in a similar way to MS2/Extra. The implementation on the chip is different, but that should be transparent to the user.

Any interest in doing a fully sequential V12 with COP? ;)

If so, how would it be done? Two expansion boards?

V12 seq and COP ? That's a bit of a stretch.

I don't see the 1.0 code doing that. The code can do V12 wasted spark now and will soon be able to do V12 semi-seq with 6 fuel outputs.

We _do_ have enough outputs to do V12 COP, but timers and pins would likely be the issue for V12 seq at the same time.

We cannot do that for a v12 with 1.0. With 2.0 we could probably do it but you would have to add 4 spark outputs and 2 injector outputs that are not planned for being on the ms3x board.

I'd be willing to test 4g63 wheel mode..It's my daily driver, so I would have plenty of drive/test time. Currently running full sequential fuel and wasted spark.

Cool, we're planning to test the same mode on a Miata so we can compare notes.

I would be glad to do testing! I make plug and play mega squirts for 2.3 Turbo fords. My car is a 2.3 turbo mustang running 36-1 wheel ,LS2 coils, boost control, 2 step running 30psi of boost. I have a mega squirt dedicated to test mule duty besides the dedicated squirt for the car. I have made a stimulator that uses an actual 36-1 wheel and cam sensor driven my a small electric motor. The stimulator also has 4 injectors, PWM idle valve, boost control valve, 4 LS2 coils so I can load test the mega squirts.

The only way to do sequencial on the road runner is with ms3 I have looked at semi sequential with ms2 and 2 extra outputs but with my setup it wont work. I have sent a PM about beta testing a while back. And it was nothing to do with trying to save money on the ms3 bord I just have lots of time before the econamy recovers and a good shop so I realy need a project like this. I have an oscilloscope and a lm-1, lm-2 and a lc-1 and accsess to a 4 gas anilizer. Let me know if I can be selected to help out. Even if I have to pay full price for the ms3 they dont look like they will be to much not when you concider I spend 110 to fill the tank and on the hiway I am getting ~15 mi/gal us. and I know I can make that alot better when I quit spraying fuel out the ex valves. Then how much cleaner the plugs will stay too.

I was planning on upgrading my 3 cylinder to fully sequential, since it is already supported by MS2. is there a need to test MS3 on odd-number cylinder engines? I run a crank 36-1 + cam trigger, COP, PWM idle, and (really big) low-z injectors.
