Yup, & the reason why they specified a particular capacity range for them is because of how many amps they can supply(or not supply). In the case of mine, they recommended capacities between 17Ah & 40Ah(so I got a 17Ah). As a result, if a motor does try to draw more amps than the dyno can handle, it's just as likely that the battery can't supply it, so it serves as an extra safety device. One of my friends, though, decided he wanted to supplement it, so he also hooked on a 20 amp power supply, & sure enough, when he tried to test a seriously powerful motor(below 10 turns), it fried the FETs on the dyno before the dyno could abort the run(this was on his Robi, of course, not mine). So when they recommend a battery, I'd strongly suggest sticking to it.....

Yeah, I tried before with an 18A switching power supply. It gives power supply error. Now I use 17Ah lead acid batt, and it works great. I haven't checked my mod motors so far, only some of my stocks. It makes a lot of difference having a dyno to check my motors or verify any changes I made really improve the motor or not.
Still using the ol DOS mode software tho...

Yeah, same here, I was going to try the demo version of the Windows software for it, but for some reason my laptop stopped recognizing my backpack CD-ROM drive, so I can't install it(I really need a new laptop)....

That's odd, I use a laptop too but it works OK; no conflict or anything. The demo s/w just won't let me save the data...

I'm sure it works fine on yours, for me it's just my laptop getting old & worn out. My CD-ROM drive for it actually plugs into its PC Card slots(it's an aftermarket drive), but like I said, it stopped working recently, so I'm not sure if the drive is bad or if my laptop's PC card slots are down the toilet. At any rate, I'm sure anewer laptop would fix all of that for me(if only I had the cash for one)....

Guys;

I did have some software/hardware issues running Windows XP and the DOS version. An update to the most current ROM-Bios took care of about 99% of of it.
The DEMO version of the Windows based software works flawlessly with XP.

What's the EPROM s/w version for the ProMaster I? Is it 2.3 or something? I have no idea how to check on mine.
I'm still using Win98 on my laptop, DOS & Demo s/w works fine. Will upgrading my EPROM make a difference? Thanks.

GTO2;

Sorry can't help you with that one.

Maybe 'Grizzbob' here, or Robert at Robitronic can answer your Eprom questions.

I want to say that 2.4 is the latest version, but I've never been sure of just how to check it(might be labeled on the chip itself)....

Is it possible and what is the cost of updraging to the latest spec, a mate has a robi in aust, and it is great for 10's and some 9's but it does not like 7's and 8's

I believe it is possible for it to be upgraded, but I think it would have to be shipped to Robitronics' headquarters in Austria, & I have no idea how much it would cost...

GTO2

I got EPROM programmer somewhere in my office...
It might work, I think need to contact Robi directly to find out how cos the software I think is avb for download...just the howtos...

Harlow

I emailed Robi and got a reply the next day on the 1 to 2 upgrade.

"Price is Euro 70,- plus shipping cost. Time is 5 days plus shipping time."

Anybody know what 70 euro is in USD.

I still use the DOS software. I have downloaded the demo version of the Windows software, and find that it produces a curve that is not nearly as smooth, and often has spikes. I feel this kind of curve leads to much less accurate readings, so I stick with the DOS software. If I get a bad curve with the DOS software I know there is something wrong with the motor.
