Title: GIpro ATRE G2
Post by: Gegs on Friday, 16 November 2018, 04:49 PM
Hey all,

I know there are a couple of posts out there re GIpro ATRE G2 and they have some seemingly good advise about balancing carbs etc but does anyone have any experience of using it on an FI model? All I really wanted was a gear selector indicator but if this offers other advantages too then it would be worth considering. Any thoughts appreciated.

I had the G1 on my 14 - the G2 from what I have read offers the same benefits but is a little more user friendly and has a few more options (and its slightly smaller).

So apart from the gear display - which in itself is a big benefit, it's smaller (so easier to find somewhere to fit). That aside, the aTRE will advance your ignition 4 degrees same as the earlier version in gears 1-4. Whilst this won't give you any performance gains, it will taughten acceleration, making it a bit more precise, which is a nice feature ( so basically works the same as an ignition advancer, except that the ignition advance works across all 6 gears (no noticeable difference). If you do choose to fit an ignition advancer at a later date, you can always turn the aTRE off and run the unit just as a gear indicator.

Biggest problem with the GiPro's - finding somewhere to mount the display. Many mount on either the top of the clutch master cylinder, or on the top yoke.

I'd say it's a worthwhile update personally.

Gegs, had my Heal Tech for over 5 yrs. Gear indicator is a must for me, no more looking for 7th gear. Shouldve been fitted standard, my 1974 gt 750 had one. ATRE also smoothed out first 4 gears, much better idea than filing out backing plate which gives extra advance in 5&6, not needed in my opinion. Fits easily, indicator also easy on top yoke. just my opinion.

Awesome guys, thanks. I'll stick it on my Christmas list  :coffeescreen:

Without starting a new topic I wondering if anyone had any practical experience fitting one of these? Torque improved in lower revs? Looking at possibly installing one to improve responsiveness at low revs  :imrgreen:

Neither TRE's or ignition advancers are ideal.

One (TRE) sets every ignition signal the same, sometimes even neutral / starting map when in reality them all being the same isn't ideal.

The other (ignition advancer) moves ever gears timing, including neutral / starting forward, if each gear benefits from it or not.

The 14 is a pretty dated design. You will find fans and haters of both, on anything modern the smart money is flashing ECU's, changing mapping and timing and removing restrictive retarding etc for each gear.  Sadly the 14 is lacking in the tech and R&D.

If you do decide to go TRE be aware that a basic one has about 10p / 20c worth of bits in it and you only need a simple resister to fool the ECU.  I still have one in a Busa to remove the top speed limiter.

If the gear indicator is of value to you and you don't like the neater clock conversion then it may justify the cost.

Can you describe the different with the tre active? I feel like for the price it may be a reasonably cheap way to improve the low rpm.

I made my own implementation of a TRE by modifying the Gear Position Sensor. I notice a marked difference when riding hairpins uphill. Otherwise the difference is subtle.

Ndp, hard to remember, been a while. Certainly smoother down low but gear indicator was my main reason for fitting.

Bike feels taughter at lower revs and more precise.

Easiest way to try this out at no cost is to mod your backplate, as if you don't like it you can put it back to standard.

that sounds exactly what I was after. From what I gather the TRE would not impact on the higher gears (since the timing isnt retarded there), however advancing timing would affect all gears? (is there potential to damage the engine doing the modification to advance timing? assuming you stay less than e.e 4 degrees?)
Title: Re: GIpro ATRE G2
Post by: grog on Monday, 23 September 2019, 10:05 AM
Ndp, correct. Healtech just advances 1-4 gears. Top pair, neutral map all remain same. Could turn mine off if you really want, check difference. Pretty much Barmys perfect description, can remember being a bit smoother, not that 14 arent smooth anyway. One of the best once all set right.
Title: Re: GIpro ATRE G2
Post by: gsxbarmy on Monday, 23 September 2019, 05:41 PM
Advancing timing (no more than) 4 degrees by the backplate would not cause any damage and would be effective in all gears - basically the backplate mod is exactly the same as fitting a 4 degree ignition advancer (available off eBay in U.K. https://www.ebay.co.uk/itm/Suzuki-GSX1400-SPS-Ignition-Advancer-4-degree-Bolt-on-Horsepower/362100593355?epid=646446472&hash=item544ee092cb:g:75QAAOSwDD9Zyjcc )

The aTRE A's comes with the Healtech is only effective in gears 1-4 as grog says

Now, if you want a pig below 4k revs, try my Diavel. They say a re map will fix, others say not. It just hunts at lower revs, stalls very easily. Very difficult bike at town speeds. Comparing to 14, which is super smooth, pulls from any revs, any gear. Diavel just the opposite. BUT, above 4g for another lots of revs, wow. Makes my spine tingle. Just goes, stops, handles, no vibration. I guess lots of other bikes give same feeling. A full blown run on it, my hands are still shaking, first beer hard to open. Just my opinion.

:lol: yep I bought thr gsx for the low down grunt, definately does not have heaps of top end but generally enough for the road =D my other bike I never get close to rev it out (07 zx10  :imrgreen:)

quick update, I fitted the healtech atre with gear indicator, feels like a different bike. Cracking open the throttle at 3k rpm actually moves you forward instead of the sluggish response before. Well worth the $  :grin:

I installed this bad boy the other day.
Went for a quick jaunt and yeh! it appears smoother chugging around town between lights etc. Time will tell (it didn't make it bad in any way).
What was a bonus was the gear indicator. What a joy. After been spoilt with the 70's and 80's Suzuki's and their gear indicators it's nice this old girl has an indicator at last.  :onya:

(https://gsx1400owners.org/forum/gallery/0/783-250720160532.jpeg)

Stuck it just below the speed dial next to the ignition (use a hairdryer to heat up and remove the Suzuki Label that was positioned there to save it if I want to reinstall it or what ever).
Anyway ... it's a thumbs up from me  :cheers:

Installed mine a few days ago. I ride mostly in the lower revs so I've definitely noticed a difference too. Feels more torquey at lower revs (not that it needed it but it's definitely noticeable) and the gear indicator is a huge bonus to me - especially when slowing down, approaching roundabouts and pulling up at the lights which are due to change at any time. I've got enough to worry about being a re(turning) rider from the 80s without having to guess what gear I'm in. I went with the holder which mounts it a bit out of view without nodding down a bit but I'm cool with that.

Wow, I wish I was as awesome as you. I find it helpful especially in the lower gears. Maybe one day when I grow up I can have a sixth sense about what gear I'm in like all the super stars. No need to be an arsehole about it. If you don't need one, don't get one for fuck's sake.

Calm gents please.

Because of the low revs / torquey aspect of the 14, many riders like having a gear indicator to show what gear one is in, especially when using a high gear / low revs. When I had my 14, I had a gear indicator fitted to mine exactly for that reason, as I kept reaching for a higher gear especially when cruising in 6th. Many new bikes have them as standard these days, esp those with the newer TFT or Liquid Crystal displays so they are becoming more common, personally I find them useful.

If you don't like them, then fine, but please respect that others do. Thank you.
