Looking for suggestions for an ECU map for the following mods

I've said my hello, and posted about what I did to my bike in my welcome post. This forum has been invaluable for eliminating the snatchy throttle and jerky low-speed ride on my new-to-me 2009 mag-wheeled Bonnie (11k miles - not too bad!).

Now I am looking for an appropriate tune I can upload with TuneECU. This is what's been done to the bike:

Predator exhaust
Baffle-ectomy
SAI complete removal
O2 sensor removal

I searched the forum for a similar question, but I couldn't find an exact match, and I am not certain how much each individual mod would change the optimal tune. I figured why not ask?

I am definitely going to do the starter relay emergency start button, as I've run into the 'I don't want to start for lack of .1 volt' issue once or twice already, and I do short hops in between my longer runs. I also remember reading about some kind of wiring harness dongle that you can use to keep the headlight off until the bike is running, but i can't find it again. It might not be worth doing though.

Anything else I can mess with while I am at it? Anything to look out for in terms of maintenance, other quirks, other small, cheap things I can do that you'd recommend? Any cool stuff about the bike that's not in the manual? Mainly looking for that tune suggestion for now though, as I have great weather and a Sunday afternoon. Thank you all!

I think there's another guy looking for this same info this morning. Sorry, I'm of no help at all, but could you somehow direct me to the TuneECU device you are talking about? This is indeed the best source for Triumph info I've come across and I'm sure someone will have the answer(s) for you soon. Good luck with your new bike, I like the idea of turning the headlight off for starting, but I'd probably forget to turn it back on and end up with a ticket. :)

TuneEcu.com, download the software, you need a good quality lead, lonelec or triumph twin power, follow the info for lead software and bingo your plugged into your bike, this utilities laptop

Your link is for the Android version, I'm not conversant with that unfortunately

TTP Breathe cover bellmouth and tune 3.
TuneECU to do it, and the software will also let you check to make sure your throttle bodies are balanced and TPS is legit. Good to check before tuning, and good to check whenever you remember.
Never had any issue with charging or hard starting...but 09s did have the old style valve cover gasket that eventually weeped, replaced under warranty easily with newer style gasket. Only problem I have ever had since new.

I have the same bike want to do same mods except a bit more civilized exhaust, will be watching for the answer.

Pointers for 2009 SE Bonnie

As you mention starting issues, I've copied a post i put on another thread, see below.
As for tuning mods, I've removed SAI, O2 sensors and airbox baffle plate. I fitted DNA hiflo air filter, bellmouth airbox intake, put a 19t front sprocket on. Changed the full exhaust system for a much lighter TEC system. The ECU retune I bought from TTP and would highly recommend it. My bike puts out so much more power now, and has loads more low down torque. I can't recommend the guys at TTP enough, as I'm a muppet with IT and they helped me immensely with the ecu tune.
I've done the same mods on my 2014 Thruxton, except the front sprocket, and the standard exhaust was replaced with TOR end silencers. There was a Triumph remap done, but I still bought the TTP ecu tune, it's just much better.
I've read various posts on triumphrat about this starting problem with Bonnevilles, and I've encountered it on a few I've ridden. First encountered it on a brand new 2013 T100 that I rode Route 66 on. Occasionally i pressed the starter and - nothing. It was a hired bike so I didn't mind bump starting it, it always went really easy off a bump. Then I bought a SE 2009 Bonnie and occasionally it would do it. I read all of the forum advice, including the rubbish about a micro switch in the fast idle lever. (Really?) My 2014 Thruxton did it the week I bought it, I took it back to the dealer who helpfully checked the starting and charging system and declared that all is fine. When I got it home it didn't do it again for months. This week I'm in Portugal on the 2009 SE and it refused to start. Pressed the starter and - nothing. Bump started easily. I thought I'd knacked the battery by linking a satnav to charge off the battery. (Only when the engine is running)
But I think I have solved the riddle. Well, I know I've solved the riddle of my particular Bonnie non starting issue. I noticed that if I held my finger on the starter button and slowly let the clutch out, it starts. So I tried it again, holding the clutch away from the handlebar grip about 10mm, and it starts every time.
So, the problem must be the clutch micro-switch. I've also noticed that this problem is more likely to happen after being ridden in heavy rain. Some of you have also linked water ingress to your starting woes.
The obvious remedy is to cut out the switch and just join the wires together.
I know that there are many, many threads and posts on this topic on this website, and I just wondered if anyone else has used this solution successfully?
Some other supporting info, to avoid all of the questions.
No, the bike wasn't in gear. Yes, I always pull the clutch in to start the engine. Yes, I always give it a little fast idle to start, even if it's a warm engine. Yes I've tried with no fast idle, if it's refusing to start, that makes no difference. When the bike's having a non-start episode, I don't get any sluggish starting sound, I get no sound at all. No clicks. No light dimming. No slow turning over of the engine. Yes, the idiot lights come on. Yes, the battery is good and it's always plugged into an Optimiser. It makes no difference if the side stand is up or down. Yes, it's charging normally.
It would be great to think that I've solved the riddle, if only for myself, of the non-starting Bonnie! But I'm guessing that one of you geniuses (genii?) out there have already found this out! I'm sure that you'll let me know!

I am def saving your post. My 2009 did it the second time I rode it. Great to hear of fixes after years of intermittent woes, cool.
