Re: Programming Curtis Controller
Looking for some guidance. I have an ev conversion of a classic bug. Out of the gates it was working briefly (1 mile) and then started dying on me. almost like it was outputting 1/10 of the power. After some troubleshooting and verifying (throttle, connections, etc)
got connected via an FTDI serial cable with the useful info in this forum. It connects, monitors and I can view settings. If I try to change settings, it doesn't save and I hear a relay click off and the setting reverts to original. At the moment, it will "works", but at full throttle, it is still outputting 1/10th or less of what it should. However, when I run the diagnostic test it will spin at whatever rpm the test is set to . Ie 2000rpm or 4000rpm. Model: 1238 7501 Protocol Version 2 serial 22728 OS Version 10 Build 70 SM Version 2.60 Param Blk Ver 1.0 VCL App Ver 1.15 As a 2nd question, I bought 1238 6501 thinking a controller swap would be a good test, not realizing its not setup with the same programming. Is the 6501 pretty much an expensive paper weight I mistakenly bought? |

Now about the -7501... OS 10 is a decent OS version, but being compiled with VCL 1.15 has crippled it. Again, a fairly basic VCL that has limited vehicle control functionality. It was designed for fork lift/truck operation, not for on-road vehicle use. You'll need an AC controller with a VCL that was written to operate an EV with more functionality. Since Win-VCL is not available to the public, you're better off looking for a controller that was designed and programmed for a true on-road EV. |

Re: Programming Curtis Controller
I found a place online that rents the Curtis 1313 hand held programmer and even that won't connect. Can anything be done to get it connecting? Is it just junk now?

Re: Programming Curtis Controller
You need more than a handheld. It will likely require a reset, then a reflash back to factory stock. I had 2 controllers earlier today that were corrupted and would not communicate with an OEM handheld, or an OEM programming station. I had to use my mobile Development level programming station to reset them, then reflash them back to factory stock, After that, they communicated just fine with the OEM handheld and the OEM programming station.

It's all about intellectual property. I respect the limits of that. I do not step over that line. I have been asked repeatedly to do that in order to override VCL limits in modern controllers. I have always declined, out of respect for the intellectual property of others. I expect the same respect for my own intellectual property. The tools that I have developed are intended to restore controllers that suffer from software issues. Many controllers are corrupted by those seeking to override limits, mostly top speed. When this is done, results can be unpredictable. The hardware relies upon careful control of that hardware, by software, to maintain operation within assigned parameters. Reprogramming must always be done with that in mind. Peoples lives are at stake when and if something goes wrong! As an OEM, I took on the responsibility to design and manufacture one-off prototype vehicles for my clients. When Curtis referred me to another OEM for VCL support, that was the last straw. I refused to deliver a prototype vehicle to a client with some other OEMs name or logo popping up on the screen! It had to be the clients name or logo, or I was not going to deliver it. I shut down that business. I have too many other successful ventures going on, I did not need that headache. So in a way, Curtis is responsible for why I do what I do now. They forgot the "little people", the end customers that bought and paid for the vehicles. They chose the side of the OEMs, their "bread and butter" so to speak, over the rights of the end users of the products made by those OEMs. Bob |

I carry some of these controllers you seek with me as I travel around the country. I'm not in the business of selling controllers. They are used as spares when I come across vehicles with issues, for testing verification purposes. I watch the various venues, like eBay, and will sometimes buy them, if the price is right. Many times, they had been corrupted, so I will restore them to original condition. More often than not, I'm restoring corrupted controllers that had been corrupted by dealers or individuals that corrupted them in order to try to squeeze a couple more MPH out of them. Most times, they are recoverable. But once in a while, by the time I'm called in, they were electronically damaged by the corruption. Bob |
