    Evening all

    Looking to decat my 17 Speedy.
    Pipe sorted but not sure weather to add a PC5 or go for a ecu flash.
    Anyone done much tuning wise? Doesn’t seem to be the norm on these here triumphs
    Used JHS racing in Bristol for my Blade dyno work & very pleased.

    I have seen some bits that are impressive with HillTop but I have heard a couple of strange issues so made me wonder

    What issues have you heard, I’ve got the hilltop map and so have many others.

    Nothing specific that’s why I’m open to find out facts.
    Read some good stuff & seen the set up & looks impressive.

    What kind of increases did you get?

    There’s a thread somewhere with before and after dyno graphs, search for Hilltop. Basically the top end is pretty strong so the gains are low down and midrange and the pick up from a closed throttle is vastly improved. I posted my Ecu to them so I didn’t have any dyno time, but my arse dyno tells me it’s much better up to 7000 rpm. It’s slightly better on fuel consumption too, not that I bother too much about that, using less fuel than my mate on his 2013 Speed Triple on a trip into Belgium last year. Is it £300 better, that’s open for debate but I’d had some tax back from HMRC so they paid for it really. :joy:

    Sounds like the type of tune required.
    More a case of good fueling & safe engine A/F ratio to match up some hardware. I’ve just not seen any dyno tuning throw up so much debate. But to be honest can’t see many facts that back up the down sides.

    Email sent to HillTop in the mean time

    Cheers chaps.

    I spoke to a very sceptical tuning guy who said if you can alter the ECU why is there only one guy in the world who can do it .... ? He also said it's easy to do a dyno run at 90% throttle then another at 100% and hey presto it's tuned ... I am not sure either way . I guess the best check is to run on an independent dyno before and after for conclusive proof. Though at the end of the day if you pay your money and it feels better it's a success ..

    a 90% dyno run won’t affect the low rev range readings, which i where the big gains seem to come with the Hilltop software.
    Will correct the Euro emissions requirements and rich furling at rpm where noise tests are done, same thing a PC5 and custom map will do but it’s seems about £200 cheaper going the Hilltop route. Only downside is you can’t remove and sell it when you sell the bike, unless buyer wants to swap ECUs.
    The power on Mr Ts RS was about the same above 7,000rpm but gained loads below.
    I’ll upload dyno sheet in a few min.

    I’ve just got round to blocking off my SAI as i’ve a decat low boy full system, all you need is a normal sized marble, lift up tank and SAI valve is on back of air box on left side. Slide the clip down and pull off the pipe and remove the clip, then push marble down the hose, replace the clip and push back on.
    Been for a spin and it’s stopped all my popping above 5,000rpm.
    I was going to get block off plates and switch off SAI valve with TuneECU, but this way was far cheaper, marble was 20p at a charity shop.

    Thanks for appreciating my curve :eek:

    I only have good things to say about Geoff at Hilltop...and yes, it all does seem to be too good to be true, but it honestly feels fantastic. Very responsive, smooth and torquey. Remember that the bad 'before' curve was caused by my stubby AR exhaust - which is what I went to get fixed. And fixed it was :p

    It's here if it helps:

    Why would you want to stop it popping???

    Did the popping increase with a decat?

    And here's a copy of my post...maybe it helps to explain how it works (assuming I understood what Geoff was telling me) o_O

    It isn't a 'map' - if I've got this right (doing my best here), it uses the existing O2 sensors to measure the exhaust gas temperature, and his firmware (which sits on unused space on the ECU's processor) reads the inputs and hijacks the outputs to make the fuel adjustments...which I think explains why you can mess with the hardware set up and it adapts to what it finds.

    Nothing changes with your rain, road, sport modes etc (other than he said that rain mode would be more punchy, so take care).

    Also, it can't be overwritten, because the firmware sits on a separate partition, in an area that Triumph won't be able to access. So Triumph updates aren't a problem.

    He also said that if anyone tries to access the partition, the Hilltop software deletes itself instantly. He appears to have made every effort to safeguard his intellectual property rights.

    It was a popping a lot, but still does I below 5,000 rpm.
    The bike had the full Arrow system fitted when it was new, and I'm the 4th owner.

    Do you recon I could run mine de-cat with twin SC under seats on the Arrow mapping?
