Booster Plug

[lt or not lt]

is it worthwhile fitting a booster plug

 

[atomsplitter]

Since you have the twin cylinder T-Bird it would depend on what, if any, mods were done to the bike. I have Booster plugs in both my Bobber and T-120 and it improved low end throttle response in both bikes. My Bobber runs V&H full exhaust and it quelled a lot of the decel pop associated with the lower restriction exhaust. My T-120 has an aftermarket silencer and didn't have a decel pop problem but was snatchy throttle off the bottom and now much improved. One thing is certain, it won't HURT your bike at all.

Sounds reasonable.

I’m a carburetor model owner, I suspect your booster plug serves the same function as jets on a carburetor model. Once you tweak the system, it likely requires an upgrade like jets in a carbureted model.

i am trying to get it to run a bit cooler , The cat is coming of and a booster plug is meant to stop them running a bit lean which makes them run a bit hotter. I have a exup eliminator for after market exhaust but looking at oxygen lambda sensor eliminator kit which seems to do some of the things a booster dose

I’d go with @atomsplitter ’s comment then.

The booster plug is attached to the bike's Air Intake Temperature sensor. It puts a measured amount of resistance into the sensor output, which drops the sensed air temperature about 20 degrees F. That makes the ECU add fuel to the injection to accomodate that sensed 'denser' air and enriches the mixture about 5%. You can accomplish the same thing with TuneECU and an adjusted fuel map. The booster plug is far simpler to use than TuneECU, it only takes about 5 minutes to install. If you want to increase fuel across the rev range, TuneECU is a better option.

Nice explanation. I guess if more mods are inline the TuneECU would be the option to take. Seems wasteful to pay for the booster plug if in the end a tune is going to be needed in the future. Just my perspective. Learning to do tunes might be interesting.

the cat is coming of ,so i will see how it runs after that and then start adding or taking away parts ,there dose not seem to be many problems of running after the cats of, some people seem to have no faults other's have to do a bit of tweeking . It seems no two thunderbirds run the same

Step by step seems like a good plan. Keep us posted!

The LTs and Commanders have a locked ECU and only accessible thru Triumph dealer as far as I know. Not sure if there has been new developments since I owned mine. There is a tune available thru Triumph called the TORs tune(Triumph Off Road). They can only do it if you have the low restriction foam air filter(again a unique Triumph part) and lower restriction exhaust. The K&N filters do not fit these models unless a new one has come out. The ones for the LT and Commander models differ from the regular T'Birds due to the frames and the air box being unique.

There are Commander and LT in the TuneECU folder list. I haven't gone in there and looked to see if they have any maps in them or not. Since the 1600/1700 T-birds were made for only a few years I'd guess there aren't a lot of updated maps out there. That said I'm also aware there is a super-charger available fot those T-Birds and that requires a complete remap of the fuel injection. To my understanding the latest Euro-5 Spec bikes have the locked ECU's to meet compliance with European air quality standards and can't be fiddled or cajoled by us shade tree mechanical types.

not after any more power or speed just trying to get it to runner a bit cooler and a bit smoother and hopefully lose one or two of the strange engine noises they make

 

[atomsplitter]

Wasn't suggesting you jump onto a supercharger, only that the T-Bird ECU is probably programmable. It's free to investigate whether DNK or TuneECU can adjust your fuel maps to run a bit richer. Pulling only the Cat off the exhaust will be a little freer flowing but a 12 minute tune can adapt to those changes MAYBE. A Booster plug will definately help. If you want to ensure any decel pop is squashed you'll probably need a remap of the bottom 6% of throttle. Decel pop is due to too lean a mix at the bottom of throttle (not harmful, only annoying).

Hi Itornotit, I fitted a Booster Plug to my 1600 TBird a few years ago, hoping to reduce the popping on the overrun a bit, but I have to say it has not made much difference at all.

It was cheap enough, and easy to fit, that's about all I could say; I've left it in there as it seems to do no harm, but would not bother with one again. My Bird is an early one, 2009, 1600cc, cat removed and a decent air cleaner and intake, short mufflers, but stock otherwise. Hope that perspective helps, cheers, Pat

Hii , i dont think anything will stop the popping on thunderbirds without a complete redesign of cly head etc , How bad would the popping be if you disconnected the booster.

ahhh...not bad really, tolerable anyway. I just tried this because I'd read about them, and one came up for sale locally, but a failed experiment, this one.

Actually have her in on Wednesday to our new local Triumph dealer to have the ecu checked to see if it has the right tune programmed into it (or whether there is an update.). The bike hasn't been near a dealer for about 7 or 8 years, so might be interesting. She runs excellently overall, and I've just been figuring 'Don't try to fix what ain't broke' you know...
cheers - Pat

have you had the valve clearance checked in that time
