thundermax

I installed a thundermax on my 12 rg it works great, except to re start after the bike is wormed, it turns over & over before it starts. if I take my finger off the start button and hit the start button again it starts right up. any buddy else have a similar problem ??????

I have learned with mine that its best to let the engine light go off before you try to start. This lets the thundermax run all its checks and get primed.

Ok, lol I don't normally mess with spelling mistakes, but I thought the bike being "wormed" is kind of funny and a first for me. BTW, I agree with waiting for a few seconds after turning the switch before hitting the start button.

Yep, very similar problem here and I also have a Tmax. For cold starts I hit the start button for a second (as soon as the red light goes off) but I don't hold it cause I know it ain't gonna start--unless maybe I let it crank for a lengthy period and I don't want to do that. Then I hit the start button the second time and it fires right up. Really warm starts, like I only shut it off long enough to gas up, as soon as I hit the start button it fires right up. But...., if it was shut off for the time it took me to drink a coffee and smoke a butt, then I know it ain't gonna fire so I hit the start button once, then a second or two later I hit it again and it fires.

I've got a 2005, so the software may be different for the older bikes, but on the basic settings window, you can change the "Initial Fuel Pulse" and the "Cranking Fuel" to eliminate the starting problems you are talking about.

The "Initial Fuel Pulse" determines how much fuel is sprayed by the injectors when the key is first turned on.

The "Cranking Fuel" will lean or richen the cranking fuel mixture.

After a little experimentation with these settings, Penelope explodes into life on the first hit of the starter button, from 25 - 105 degree weather, or after sitting in the garage for 5 months all winter. It doesn't matter if she's ice cold or only been shut down a few minutes.

So check the manual for your T-Max version and try some minor changes to see if it helps.

Have you used the automap yet? After 4 or 5 riding sessions you should hook in your PC and run the automap. A riding session is considered riding the bike for 25 to 50 miles then turning the bike off when you restart the bike you will begin a new riding session. When you run the automap the module will read and learn your fueling offsets and make adjustment as needed. You should do a automap 3 or 4 times for the best results.

You can also do a idle tune which should be done when putting in a new base map or before you start the auto map.

Remember the T-Max will only auto tune the AFR and it will not auto tune timing adjustments, if any timing adjustments are needed they have to be done manually.

If your problem continues you should do a DATA COLLECTION and send it in to T-Max support with a discription of your issues.

Do what Mark suggests in his last sentence.

I had the same issues with mine. I was getting ready to do as Mark suggested above, but when I opened the Thundermax program on my computer a notification popped up and said the map I was using had been updated. I downloaded the revised map and I no longer have any hard start issues hot or cold.

thundermax

...I do notice that every now and then, my bike will hiccup on cold start-ups with the Thundermax. however, I must admit I haven't dialed it in since I installed it 3 weeks ago. The one big difference I noticed is that my motor runs so much smoother and has a nicer exhaust note. The throttle response is also lightning quick. Overall, I very happy...

I am not a tuner/tech by any means but have a Tmax on my '11 RGC with Dragos pipe and SE heavy breather and cams. Base map from Dragos was real good and bike ran smooth. Was down in Daytona and went to the Zippers tent and paid $50 for a 'check-up', this was back at Biktoberfest. The tech downloaded new updates/software, checked how the bike had been running and tweeked a few things. Bike ran nice before, now it pulls hard all over. I had 255 cams put in and always thought bike should have more low end...after re-tune I can see the benefit of them now, although still a mild cam. If you are ever at a rally and they are there, IMO it is worth the $ and let them ck out your bike.

+1 on that. My bike has never run better than with the T-max and for someone like me who changes things a lot it is the way to go. It is kinda picky on the start-up procedure.
