TRE mod?

I've read a bit about a device known as the "TRE" (Timing Retard
Eliminator). It's an aftermarket module that inhibits the function of
retardation of the ignition on most current Suzukis (including the SV1000s
which I own). The effect is clamed to be better torque and "less
snatchyness of throttle" at low rpm (<4k). So basically, 2 questions....

1. Is it worth it (on an SV1000s)?
2. Given the above answer is "yes", is £24.99 a good price for a fancy one
that stops retarding in neutral (not the "resistor in a box" jobbie)?

TIA

 

Well, in the 160 miles you've ridden the bike, do you find the throttle
snatchy? And as for torque, perhaps you should let it run in first.

 

Man, you're on the ball.

OK, I see where you're comming from. I am not a newbie. I am just
wondering if I can make MORE miles on my new bike even better for as little
as £24.99.

Thanks

 

IIRC, Gower did this on her bike (gsxr 1000) for a fraction of the
cost. If you google-groups for it you might find some information.

 

I'm guessing: 10 - 15mph faster everywhere?

 

You are!

No, wait..

 

Made a handy difference to my Bandit 12, mind. Fucking hoot, that was
- but it was only a matter of pulling a connection apart, so it was
free. 25 quid? Depends what 25 quid means to you, really.

 

I've thoughjt about it, and decided it's pointless. The thing is
smooth enough anyway.

 

Good point - on bikes like the Bandit, and prolly the SV, it prolly
*is* worth having. On a gixxer thou, it'll flip you off the back in
1st and 2nd anyway, if you want it too, so I don't really see the
point.

Quite so.

 

It only affects the first two gears [1] (not neutral, ytc!).

ytc? Ahem, let me explain.

The gear position sensor which connects to the ECU DOES have a signal for
neutral. On an unmodified bike, the ECU retards the ignition in neutral and
in gears 1-4 (not 5 & 6). There are different ways of doing the TRE mod.
The simplest method is to fool the ECU into "thinking" that it is in 5th
gear all the time by disconnecting the gear position sensor and bridging the
appropriate wires to the ECU with a resistor. The downside is that the
tickover becomes unreliable as a result (needs retardation for reliable
tickover). Some people fit a switch to enable/ disable but to me that's a
PITA - I don't want to have to fiddle with switches every time I go into
neutral. The units which cost £25 connect between the GPS and the ECU and
electronically switch the TRE off in neutral.

ytc!

 

Well, I stand corrected. I can't really understand why the ignition
needs to be retarded to get a reasonable tickover, but I'll take your
word for it.

 

Well, I stand corrected. I can't really understand why the ignition

...or why a bike manufacturer comprimises the ride by retarding the
performance in the lower gears (ok I see the point with yer gixxer thou but
not a bleedin' SV!) It's not just the low down torque that's comprimised
but the smoothness. I don't think the 4 cyl bikes are as affected but with
a lumpy big twin, the effect is added lumpyness which makes smooth
throttling in town traffic a bit of a chore.

 

Emissions may be part of it.

Emissions may be part of it.

Good point.

 

Gearbox protection as well - reduces their warranty from people repeatedly
dumping the clutch in 1st and 2nd. Worth considering the effect on longivety
if you do make the mod.

Go on, say it. Or he'll be doing that all night.

 

In the man, yes.

I think I'm on the turn.

Still, I'm just happy I got through the whole day without beating our
data services manager in a bloody pulp.

Do things like this happen elsewhere?

Meeting with DSM bloke; he expresses concerns over deviations from SOP
over this new project. I point out that said project has been "live"
for 2 days, and that he was invited to provide resource to do the job
I ended up doing. I suggest I'll note his concerns, convey them to the
project, and convene a meeting to discuss same.

Walk in this morning to the mother of all shit-storms.

He's emailed all and sundry thanking me for a: taking his concerns on
board and b: agreeing to change procedure changes (both ours, and the
client's) to fit in with his wishes.

Apparently, there was "no need for that kind of language".

Situation well on way to resolution.

I'm currently going with the supposition that I don't actually have to do
/anything/. Any time I've moved away from this position, I've picked up
jobs[1] and aggro. So I'm spending my days holding back from involving
myself in even interesting-looking work, because I know what'll happen.

I'd quite like a proper job now, please.

[1]Not useful jobs, just stupid, arseing-around, bullshit stuff that gets me
into meetings, workshops and 3-hour conference calls.
