Doing some ignition mapping on a custom sled
« on: August 07, 2014, 07:52:31 AM »
I have been asked to write a custom ignition map for this sick custom Sportster, built by a guy here in my home state of Oklahoma. I've been writing custom ignition maps for some HD Sportsters for a few years now, for folks all over the world. But this is the first time I've been asked to do one for a killer custom like this:

It seems I'm a bit remiss in saying hello.

I can't help you on the bike but it's cool to see another American here.

I somehow missed before that you're in Oklahoma.

I'm not all that far away. I live in Tennessee.

Again, welcome.  :-*

What would you like to know? I only write maps for one kind of ignition currently, and that is the TC88A from Daytona Twin Tech and it's clones. It started as an accident really, several years ago as part of my activity on the XL Forum. As I developed my mapping skills, folks began to hear about me and wanted custom mapping for their bikes as well. Now I have people running my maps in all 50 US states and 140 foreign countries. Several folks in OZ are running my maps too. Here's a screen shot of some of what one of my friends calls Rico's Dark Magic. This particular map is written for Sportsters with a high compression 1250 kit:

That's fantastic !!


I run a TC88A also so this has really piqued my interest.  What kind of software do you use to write the maps ? How do you upload them into the TC88A ? Do you use a dyno to work out max advance for a given rpm band or is it an experience thing ?

The software is available for free on Daytona's website. You need the PC Link TC88 program, and the TC88A Logging program, plus the USB driver. To upload them on a Sportster anyway, the number 2 wire in the main connector to the ignition module is replaced with a white jumper wire...the other end of which runs to the empty hole in the diagnostic port. See here: http://xlforum.net/vbportal/forums/showthread.php?t=1525483

For a quick and easy how to on remapping the module...see this post on my blog: http://jestermotorwerkz.blogspot.com/2013/02/reprograming-tc88a-ignition-module.html

Both seat of the pants and dyno testing has been done on my mapping.

Hey I'd be happy for you to pen an article on tuning TC88A's if you're keen ?

I can do that, it will be a few days, as I'm just slammed at work. Anything in particular you'd like covered?

I'm liking this a lot.  I'm just getting used to not having to clean, gap and set my points.   pappychris.gif

I will try to get something put together soon. The old lady is having surgery on Tuesday...perhaps I'll use that time waiting in the hospital to work it up. I hate fucking hospitals.
