Ignition module replacement
Hi there
Wondering if anyone can offer some advice. I am having a nightmare trying to replace my broken ignition module. I have tried a number of parts dealers in the UK who cannot help. I have also tried three different HD dealerships who have been quite unhelpful tbh. My local dealership offered to do the work, but I simply can't afford their prices, so I'm trying to do it myself. My bike is a 1999 Dyna FXD with a stage 1 upgrade. The part code from the unit I took off the bike is 32479-99 followed by 99062. I am considering either OEM or aftermarket.
My questions are...
1. Does a replacement have to be the exact same code? In the parts catalogue, it says the code above is for 'international models only', I'm guessing because my bike was sold in the UK, they put an 'international' ignition module on it once it got here. The code for the US models, on the same bike, is 32478-99C, obviously slightly different. Would a US ignition module work on my bike, or does the code have to be exactly the same as the original one on it? Many of the aftermarket modules such as Dynatek TC88-2P say they are compatible with the latter code (32478-99C) so I'm concerned they won't work.
You can see the two different codes on this page - https://estore.manchester-harley-dav...mbly-273090~13
2. If I reinstalled an OEM ignition module, does it need programming at all, or is it simply just plug and play? I have a stage 1 upgrade so would anything need to be done regarding this.
3. If I went for the aftermarket Dynatek for example, how do I know what to set the 'advance' to, and how high do I set the rev limit, again, given the fact that I have a stage 1?
Apologies for any stupid questions, I have no experience of doing this.
Any help or advice would be greatly appreciated
Thanks

Re-install your OEM unit ....Its plug & play and you do nothing other than mount the unit..... .Its nice to have an adjustable ignition module if your running a few more bolt ons than you are running. The stock unit will work fine for a stag #1 If any thing you may need to tune carb. I have associates who run open AC and pipes with stock ig.mod. and theyre fine. No popping and no hiccups. Throw it in and go for a ride ...weather permitting in UK .................................. ** you said your OEM unit broke. If so then order the stock unit (international) since yur bike was sold in UK I presume and you will be back up n riding. If after yu decide to mod bike with aftr mkt. heads and possibly bigger carb , possibly larger displacement, if so an adjustable ign mod unit would help. There is also (or was) a screaming eagle ign. mod sold at one time when carb bikes were still being sold. It may have a bit more aggressive timing & fuel/air ratios programmed into it. Id say stick to OEM and enjoy it until you gather more experience on what you want from riding and your bike. It will be reliable and still fun to ride

Thanks so much for the response Torky_sob, that's really helpful. I'm gonna do exactly that.
Only problem I've got now is finding the 'international' version of this part is proving nearly impossible!
Do you think that the US version with the slightly different code will still work on this bike?? Or has the bike been configured to the international version or something similar?
Thanks

I live on the other side of the street from TORKY_sob. Go AFTERMARKET! HD stuff is all EOA Compliant. Stage 1 with aftermarket ignition will liven it up a bit. Look on ebay for a Dyna 2000i ignition unit. Gonna have to cut and crimp some wires but well worth it. As far as settings, go with the the highest rate advance curve. RPM Limiter to 6000 rpm. YOU WILL LOVE IT!!!!! Stay away from ULTIMA, it looks exactly like the Dyna buy it's pure crap.

Hey TDW.
I have one of the adjustable modules, all it did for me was burn up spark plugs, I went back to the original module and there's little to no difference.. I have a few more mods, cam, heads, went gears and have been playing around with a carburetor combination recently... I might try the adjustable again? But for now I'm keeping the stock... And the plus is I'm not burning up plugs..

Thank you guys for your comments, much appreciated.
I went for the Dynatek aftermarket in the end simply because getting an OEM replacement was more difficult and more expensive!
The bike is up and running now, need s a bit of tweaking but so glad to be back on the road.
All the best
