So this has been on my mind for a while, and thought I should post it here and see.

I had the TRE on my bike, and I took out the flies and went for a quick ride (with TRE/6th gear still on the bike), and of course it felt pretty responsive to the throttle and all was well. After the quick test ride, I put in the PC3 and loaded a map from dynojet (slip on, no flies) and went for another test drive and it was all good too. Then I took the TRE off, but never went for a test drive after.

A couple of days later I rode the bike to work and back, and although I loved the way it now behaved, I kinda sorta felt that it wasn't as 'jumpy' as it was on my second test ride (with the PC3 and TRE still in). Now we are not talking a considerable amount of difference, just a very little difference, and frankly it could very well be all in my imagination.

I don't feel like putting the TRE back in for now (just no time to spend in the garage, really), but was wondering if anyone else knows whether there is actually any timing retardation taking place or not in the first few gears. I have tried to compare throttle response between 5th gear and 6th gear on the freeway back to back, and can't really say if there is any difference or not... but I wouldn't be surprised to hear that there is timing retard being done in lower gears.

I have been thinking about going with the TRE (neutral) to eliminate the popping, but the popping doesn't bother me enough to justify losing my gear indicator again. (I like having it.)

So, has anyone done any with/without TRE comparison (flies out)?

Well faz, I could not have said it any better. I do not know about that lag or timing retard without a sniffer and a timing light to watch. So, I have no clue but to match your seat of the pants evaluation. I do not run the hacks or the codes or the limp or the tre.

More like this is a, "lag indicator" where it should be a streaming billboard that where your dash has the numb beers should be reading... "Tre = Test Rear End" < For your lagging indicator is a window wash.

Keep it off. You can tell the thing runs a lot better in the analog, can't you?

Faz I think all the big sportbikes have some reduced timing in the lower gears to keep folks out of trouble

Thanks guys... sorry I have been away and not checking even the thread that I started. Life has been very busy!!!!

Thanks for the feedbacks... I know for sure about the timing retardation in SV650 and SV1000... had both bikes before and there definitely was a measurable difference between TRE'ed one and stock one. In my wife's 2001 SV650 case, it was as easy as removing a wire from a connector under the rear seat. In the SV1000 case, I bought the TRE.

As far as the ZX14 is concerned, I was hoping someone had done back to back testing with/without TRE, but it seems like folks (at least on this board) haven't done that... or perhaps they don't care to do a comparison.

If I feel like losing the gear indicator again, I will try and get the "N" TRE (or the resistor substitute) and report back my findings.:)

I'm using a GiPro so I can turn the TRE on/off.
Seat of the pants, I can't tell the difference.
However, I've read that tested on the dragstrip a TRE'd bike is slower by a couple tenths.
I've only used the Gipro in the "nuetral" setting or off entirely. Never tried the "6th gear" setting since my bike had the flies removed before getting the GiPro.

thanks dogo... can you try the 6th gear setting (is it easy to do?) and share your finding here? Now that I think about it, I can see the timing retard still being applied in the Neutral setting as well (no performance reasons for or against it if the bike is in neutral, right?)

Today I rode the bike to work and back... on freeway I kept trying the same rpm roll on (4k) back to back between 5th and 6th... in 6th gear the bike seemed 'livelier' that the 5th gear. I thought perhaps this is just me wanting to feel a difference, so I tried a few times with only my right hand on the handle bar, and sure enough, the 6th gear roll on kept throwing me off balance more so than the 5th gear roll on did.

I don't think I am going to put the TRE back in even if it proves to be livelier... the current power is sure good enough for me... but all this curiosity is now built up inside of me! :))

No problem, it's easy to change the settings.

Don't know about the TRE-but I did install a Muzzy Timing Advance trigger-4 degrees advance.I DID notice a snappier response-didn't affect my temps.I've got a PCIII usb Race Model mapped for 07 "secondaries removed,stock air filter,stock exhaust".I'm assuming that it advances ALL THE WAY through the rev range since it's a set and forget deal.Works good.$85.00 at Muzzy's..I also had one on my ex-zx12-there definitely was a noticeable peppiness.

Nice. How hard to install? (I'm a noob)

After removing the lower belly fairing,then the timing case cover-oh,about two minutes!(EASY-three little allen bolts on the advancer,replace with new advancer to the setting,then reinstall the allen screws-yer done(with that part).
