it's a timing retard eliminator. it also eliminates the top speed limiter. the stock maps have the timing retarded in the first 3 gears, to reduce some power (for whatever reason). this just makes the bike think it's always in 4th gear, so it's always making full power timing-wise.

is this something that will void a warranty if found by the dealer? also, i guess it wouldnt make a difference wether i have th jsd or not if a person drives slow, like myself?

The difference was felt MOST to me in slow speeds. The jerky starts from the stoplights were eliminated and low-end handling became easier for a new rider like me. However it did make the cat die and knocked up the neighbors wife....
( Old jokes from MANY posts ago...) Honestly it was great bang for the buck and I have been completely satisfied. The other benefit is that I can peg out the speedo at top end in 5th. Not something I do a lot, but fun when the urge is there!

another way to fix those jerky starts is to launch at about 5000rpm :bigthumbsup: :p It worked for me :D

How do I install the JSD? Is it a plug'n'play or is some major soldering and wiring mods to be done. I didn't find any instructions in the "how to" section.

About the knocking, If the timing in 4th gear is the same as the JSD gives the logical thinking tells me not to worry. Suzuki would hardly produce bike that would always detonate in 4th gear, would they?

Plug-n-play, no wire cutting... it should take under 15 minute including a "smoke break".

Here are some pics of the install:

The JSD-3M does not ever advance the ignition any more than Suzuki does in 4th gear. So if it "knocks" from the factory, it will knock with a JSD-3M installed. A stock bike will not knock...... if you plan on doing air filter or exhaust mods... I do suggest a power commander and getting your bike properly mapped. This is not because of the JSD, but because you have changed the input or exhaust subsystem and the stock Suzuki ECU can't compensate for it.

Should you get the un-switched, switched or automatic? I find thier descriptions lacking in what the differences are.

Thanks

In his defense, he was asking if it was something that would void the warranty if found by the dealer... not telling.

Funny, it seems he deleted the post just as I clicked to respond.
Yes that's how I read it also...he was asking if it would void the warranty. However the link Perry provided is good reading for those questions.

:2cool: That's a great find ppridgen! All should read!
Thanks!
bump! :agree:

That said, if the TRE is the part that failed (hypothetically, Jeff ;) ), then the dealer could reasonably charge you for non-warranty repairs to replace the TRE or disconnect it, etc. Point being - you're only liable for repair costs if they (dealer, mfr, etc.) can prove that an aftermarket part caused the failure.

BTW - I'm hassling right now with a Nissan Dealer in Puente Hills, CA that sold me an Injen intake and a grounding kit for my '05 350z and now my check engine light keeps coming on (O2 sensor code)... So far - over the last year - they keep , erm, *attempting* to fix it, but haven't been successful. Last time I was in, I was told to put the original intake back on so I don't get oil (from the filter that came with the intake) on the MAF sensor wire and that if I don't, then the next MAF sensor replacement is on me. Nice guys... hmmm... I wonder if they'll refund the parts they sold me and the labor to have it installed and removed just to put the car back to stock...
Not! :eek:

Only way not avoid trouble is to ride your bike w/o any mods at all.... or you can establish a relationship with your dealer so when it comes time to repaid they are working for you.

I have never heard of a single JSD/TRE type device (in 6 years) ever cause engine damage or void a warranty.... but I have heard the sky is falling.
