Hello all,

I have a 2002 Dyna with TC88 engine, it has a Dynatek "TC88-2P" ignition module that can be programmed with a software called Curve maker , available from Dynatek.

To do the programming there is a cable that connects the 4 pin diagnostic port on the bike to a rs 232 serial interface on the computer.

This cable seems hard to find here in Europe and is also quite expensive so I want to make my own.

Does anyone know what pins to connect, maybe someone has the cable and can measure it?

Thanks in advance

 

I don't think you are going to find that the interface cable is only wires. I recently did some work with a Dynatek 2Ki and pulled the cable a part.. I found a small circuit card installed in the connector.. I'd expect that the TC version might also have some sort of interface card. It's probably the reason why the cable is so expensive.

 

I might have one. Probably cost even more to ship tho.

 

Have you tried using a USB to RS232 adapter ? Like this for example ?


hth,

T.

 

He'll need a RS232 port on the computer. If his doesn't have one, then what you show will be needed, still it needs to adapter shown here.. I'm not sure what the difference is between the programming kit and just the cable.. Programming kit might include a power supply? I believe the software is free..

 

If the one you have is for a DTT, it might work, but then it might not..

 

I'm not a TC guy, no experience to speak of.

But on an Evo Dyna ignition, there are only 4 pre installed/select by switch curves and even at that, using a program cable is basically a waste of time unless you need to setup for a kick start or a few other neat things just for play and you can use the same hardware on the less expensive Ultima version of the same ignition. No advantages otherwise.

The TC88 version has 16 switched curves. To me, a programing cable is even more unnecessary on a Twin Cam but again, I don't have any experience with them and it's your toy, not mine




Board inside Dynatek programming cable for the D2ki ignitions.

I've no idea whether the interface adapter identical in the TC88 ignition. I can get you a link to a thread in this forum for a schematic of the D2ki adapter but you'll have to ask me. (it'll take a while to find). No guarantee it'll work and/or not destroy your ignition if incorrect.

Best advice would be to buy the official cable despite the cost and wait time, if you really think you need or want one.

 

Thanks a lot for all your input, I did not consider the possibility that there was some electronics embedded in the cable, but now that I have seen it it makes sense.

There is no point in trying to reverse engineer it to make my own, I will just have to save up some cash and buy it.

The reason I want it is to be able to tweak the curves some, there are 16 available curves but they all have quite aggressive advance increase at high rpms, I want to be able to change that
