Techlusion TFI / ecu quick question.

[arveno]

Good day everyone.

after following the decent tune up instructions found here my 2002 Le Mans still runs like crap .

way too rich the plugs are black.

the distinguished previous owner installed this Techlusion TFI thing ….which no matter what I do It makes the bike runs too rich.

if I just remove it ?

Is the 02 ECU ( believe is the 15M) good  enough, right?

I don’t really like PC bla bla bla… I am not a computer guy and the 02 throttle body efi seems so simple I don’t want to mess with it.

i thought the bone stock factory ecu should be good enough…. Am I correct?

Let me know what do you think 

thank you

Agreed. Probably won’t even need to re-do the tune, just reset the idle if necessary.

Remove TFI is my recomendation

[arveno]

I will remove it and report back.

 Thank you

   Yank that sucker !!   If you haven't already, I'd pull the dipstick and see if it smells of the gas from overfueling.

Try it w/o that TFI addition , install new plugs , check the oil for dilution and ride it for an afternoon to make sure you feel an improvement .

Bingo !!!!!

the oil smelled like there was gas in it .

dropped the pan and replaced filter and oil and of course new spark plugs.

taken the piece of …… ( tuner) off my bike .

started the bike and she runs beautifully.

ad to do a few adjustments but now it’s another animal compared to what it was before.

I still don’t understand why someone would add a piace of crap “ tuner” to a bike that runs good from the factory.

oh well…. 
as soon as it cools down a bit I am gonna check the plugs .

thank you all

I HAD a tuner on my bike and spent a lot of time & money trying to get my bike dialed in to find out the tuner was at fault .

(Sigh.) While it is quite possible to improve the fuelling above and beyond the factory mapping adding any of these *Magical* widgets is an utter waste of time and money. The 15M and 15M RC ECU's have been an open book for well over a decade and modifying the maps is a far more accurate and useful way of going about things than adding some shitty little resistor to deliberately screw up sensor inputs.

Just say no to hocus-pocus! You know it makes sense!

I know it is possible to improve the stock mapping and that might be the next step. 
as of now I am glad I went from a crappy unrideable bike to a very smiling riding bike .
