You might drop a couple of HP where you spend 1% of your riding time to get rid of most of the shitty running where you spend 99% of your riding time. Good to see someone not bothered by one peak number and is more concerned with how the rest of it is. :thumbup

The thermostat mod is one to do to, so whatever ECU you're running with at least gets an accurate engine coolant temperature reading and has half a chance of getting some of the mapping right.

After reading this thread as well as the link posted by Steve, I assume this doesnt apply to my 2000? This problem was addressed by then?

Look here, I posted it up earlier >> http://wotid.com/tls/content/view/25/49/

The 32920-02F00 is the one to take notice of. It should have bee swapped for a 32920-02F01 in the bike's early days. Over here, the (10/97) '98 and up came with 32920-02F60

:no The TLR is a different animal altogether. You should note that there are folks who would very much like to have your original '97 ECU. You might even be able to arrange a swap for an updated ECU with one of them.

There are no perks with the original ECU. Not unless you're interested in one peak number at the very top end of the rev range. Good for bragging rights, not much good where you spend 99% of your riding time.

You have to do the thermostat mod to improve your economy too. Fitting a later ECU is only half the job ;)

I think the '97 is unrestricted - though adding a TRE to a later one should bring it close to par with the '97:O. The '97's fueling was sposed to be worse, with stumble etc; and they were sposed to "drift" (out of tune:confused) whatever that means. They are a bit of an ikon - makes the bike an original 'Widowmaker':devious. I think this dude may have dyno'd both, though i haven't been to hi site in a while: http://homepage.mac.com/rg500delta/TL1000/Randys TL1000S page.html


I think the best way to fix fuel economy is to do the temp sensor mod, if it hasn't been done. Steve and I have both alresdy given you the link for this. Go to my first post and click on the underlined text, if you haint already:).

Just read Randy's back to back ECU test - accoerding to him the original '97 is more powerful throughout the rev range - pulls like a schoolboy....

.......
The original '97 with an original ECU, still had a gear position sensor fitted and fed the ECU with gear information and it altered the mapping to suit. The difference in mapping depending on clutch position with a static TRE can be observed in the 97 and 98+ TL's so the '97 ECU was using the gear position information.

There's just not a lot of '97 TRE's out there as it was the only model to use a 2 wire plug, all the rest used a 3 wire plug and you can't make and sell a true plugand play 97 TLS TRE, you have to connect a ground wire.

Yeup, mines a two plug, I made my own TRE thanx to WOTID:). I have read a lot of stuff that suggests the original '97 ECU does not benifit from a TRE:O. I'll try and hunt it down in the next few days.

Though, I haven't seen it on TV, so it may not be true:laugh:laugh(bastardised CCR:laugh)
