Hmm, I guess I should hold off buying mine if there is a firmware update to be implemented.
Actually, thinking about this, how difficult would it be to re-flash the GOODbox? Is it a question of having the correct cable and software on your PC? I am wondering if it is a DIY job, because buying a serial cable might be cheaper than actually shipping to box back. :) |

Then all you need is WinAVR to upload the correct firmware files. If anyone wants to play with this, PM me and I'll explain the details. At the moment I do not have any updates to implement. The upgrade HiFlite999 mentioned is already complete, and is on all new GOODboxes, including those shipped last week. It resolves a possible corruption in the saved data regarding the AUX inputs, it is likely that you won't run into it at all. If you ordered earlier and are using AUX inputs and are experiencing issues with programming the AUX text, you can send it to me for the firmware fix. |
Okay, cool. You have my order. :)

Finally, I'm not sure I'm zeroing correctly for the boost gauge. If I set it to 0 with the engine off, it will rangfe from -10 to say +3 psi while driving. If I set it at idle, it will go down to -2.5 when engine breaking and up to 12ish at full boost. The second seems more correct to get an idea of "extra" boost provided by the turbo, but it seems odd that at idle the absolute pressure is only 1/4 of the normal atmosphere pressure (-10 psi = -0.75 bar relative to outside). Comments on the last item would be great, and updated firmware for the garbled input would be even better, although postage will become a killer. Car people however reset the true zero to -14.7psi, sorta. The 'sorta' is that this method depends on what the air density is when you push the zero button. Push it at sea level on a standard day (barometer setting of 29.92"Hg). Engine off it reads zero. Now drive to Pikes Peak and shut off the engine; it now reads about -5 psi. Sliding the zero around this way makes everything unnecessarily confusing, and changes what "boost" means depending on the outside air density. "Boost" doesn't matter! Only the pressure in the intake manifold matters, not vacuum. (And the pressure only matters because it's roughly proportional to MAF which is the number that really matters.) If you want the gauge to behave in a way consistent with the automobile world, zero it with the engine off. Autoworld: -14.7..............(vacuum)........0......(boost).. .....+10 Skyworld: 0....................(pressure)..................+ 25 |
Just a thought regarding the "slot machine" effect to those who've experienced it.
Was your A/C on at the time? |
^ yeah probably...

i am all out of fresh boxes, but the box i used is a customized hammond 1551k. You can buy those on digikey for $2, but you'll have to dremel out holes for the buttons yourself.

Pieter, have you not experienced any display problems with your install?

Could the scrambled screen be caused by a fluctuation in the power supply??

Are you still enjoying the project Pieter, or is it getting to be a PITA?
I'm still amazed with what you've accomplished, and in such a short period of time. |

Hey being an innovator is not an easy task. I look forward to your future endeavors.

^ Couldn't agree more.

Just picked it up... $29 shipping.... but no biggy... the kits linked from the manufaturers page were all in the $300 range. Thanks!

How about reading the fuel economy averages? LOL :P

By the way, Pieter, any idea how long international shipping is likely to take? Days? Weeks?
|
Got mine last night :)

San Antonio is a lot closer than Cardiff :)

I think that I ordered mine just before 9krpmrx8 ordered his (on wednesday). I assume that they were shipped at the same time, but I'm still waiting :( I'm in Wales
