Mach II problem

[sl4ck]

I Mod my Mach II ST @ Mach II, with an homemade USB Cable, and installed the Mach II Control Centre Software.

Win XP recognizes well my Mach II ST as Mach II, firmware update is possible by the MAch II usual way (Mach II Bootloader), and i made it with diferent firmware versions.

The problem is this: with the evap unmounted on the CPU, i have temps like ...34ºc...43ºc...56ºc...65ºc...etc on the Mach II Control Centre , i think is the evap resistor getting hotter, when i turn promy on and it gets ice on the evap it shows 99ºC on the Mach II Control Centre like picture above.

Do you know what could cause it?

Evap sensor damaged?

PS: It is modded with r404a

PS2: do you what could cause promy starts since i plug in the 230v cable?? No need to turn the power switch case on.

Sounds like the control board has gone bad try reflashing the firmware to the newest version if that does not fix the problem you may need to contact phil for a new control board

If your firmware is corrupt your mach2 will switch straight on just by plugging it in to the mains

I already flash it, but not to the newest, the one that fixes the boot problem.

What about the evap temps issue, what do you think?

This can only be a couple of things first like I said your control board may have gone bad

Second bad temp sensor

or

Third you may have a leak

but it sounds more like the control board has gone bad

what should be the evap sensor value range (ohm) disconnected from the board, so i can test it

About the board, what can i do to fix it ? or change it, and how much it costs?

where can i get evap sensor if it is broken?

I would like to contact DJ_IVOCHA but he has no activity since 18-08-2004 so i expect no reply, do anyone knows how he solve the problem??

Looks like it was Evap sensor or control board, but i don't know wich one was

I had this problem with my MACHII but it was a software problem. It was doing all sorts of weird things, so I had it flashed. Which sounds simple, but it wasn't!

I suggest you measure your sensor and see if you get the same result as that fella. I assume he ended up with a replacement board...

More than likely the board tbh
