How to set the TPS on a 2009 SMR 510 ?

[Juvkam78]

Have installed the Arrow twins and ecu on my bike and have only started it a couple of times, it seems to run fine when cold but wont idle after a few minutes,the idle screw is all the way in.. it also hesitates, backfires and dies when trying to give a litle gas.. Have read abaout that i need to sett the tps with this new ecu, is this something i can do by my selfe or is a diagnostic tool needed ?

Regards Juvkam

You need the iBeat software from Mikuni. A dealer would have it but not sure how much they'd charge to set the TPS. Only takes a few seconds after the bike is warm and connected.

In the States many guys have bought from Scott at Semco. Sometimes dealers are too far away and it's a good choice to have your own tuning software.

Hi there. Just curious to know what the benefit of the race ECU is? I have the 02 bypassed and have fitted a K&N filter, also removed all the restrictive stuff incl cats from the end cans. I've not run it yet as still rebuilding it but was thinking that a trip to the dyno shop would sort. Bike is same as yours, 09 SMR. Thanks

Thank you for a good and quick answer, my dealer is a two hour drive from where i live so maybe i should look into getting the iBeat my selfe..

@moto66: from what i heard the new ecu has a difrent map custom to the new pipes, and raises the rev.limiter

Thanks Juvkam. I've had bikes for years but never EFI, learning as I go! So the race ECU kind of does away with the need for a Power Commander as it has a preset map inbuilt.. I think a lot of guys here, esp Stateside have big changes in altitude and the PC and Autotune must really help for optimal fuelling. I'm at sea level, no change. Have always had bikes dynoed (plenty local) so will see what gives with the standard set up. I think you're going to notice a big difference when she's all sorted, the OE cans are so restrictive. Nice one

I have been running the Arrow ti twins with the upgraded ecu from Husky for almost a year now. My bike runs good with that set up, but I also run 100 octane race gas and that made it run even better. I am thinking of getting the Autotune from Power Commander at the moment. I think that there is a little more power to be found in the ecu yet. I have also thought of getting the i-beat set up, but you still are only adjusting by the butt dyno and not true A/F ratios unless it's sitting on the dyno.

With the current set up it makes 54hp/36tq to the wheel.

Ibeat will only allow you to control 3 areas, CO1,2 and 3. Whereas a PC will go every 10% of throttle and map for that, so yeah you can do more tuning with a PC than you can with the Stock ECU's and IBeat sw. I am running the Husky Race ECU in my 310 and love it. Finding another couple HP for me is not even worth my time, but for track guys on loing strights, I cansee where you want every ounce you can tweak out.

Hi Gutzy. Seen your posts on SMJ. Nice machine you've got there. So - and hoping this of help to Juvkam - as long as the dyno shop has access to ibeat software they can still run realtime air/fuel setting up (in 3 areas I think) with the stock ECU. And as long as the power curve is reasonable, and she's not running lean, should be good to go? Just won't see the higher rev limit - as per the race ECU - not that it concerns me on a large single.

54 horses is plenty respectable on such a light machine.

Am not racing, no tracks!! So for street use stock ECU sounds fine with some tweaking. Interesting stuff this. Learning here

This was when I first put the kit on. The bike only had 800 miles on it at this point, this is on 91 pump gas also. First run stock in blue second with the kit on in red. With race gas and being broke in, it runs a little harder now.

 

[moto66]

That shows a stable increase through the whole range. I wonder if you would gain that much more with PC and AT? I guess your motor revs a lot more freely with the kit on too. I'm only up to 800 odd miles on my motor but noticed even with all the stock exhausts in place how much better it was getting as the miles ran by. I run mine on 95 or Super as it's called here. Costs more, not sure if there's a difference but it makes me feel better

 

[GUTZY]

In my opinion on the SMR bikes getting rid of or gutting the stock pipes it a big deal. The ecu that comes with the kit helps with the tuning to a point. But for a true real time tune, the AT is the way to go.

 

[moto66]

I agree. I've never ran any bike with OE pipes. My SM would rev but it felt so strangled and the plug was black, just not getting the air/fuel in exhaust out quick enough. Done the careful run in miles, re-cored the cans and am slowly getting her back together. There's some excellent and real technical info on EFI here too.

 

[GUTZY]

What size baffle did you use when you re cored them?

 

[moto66]

I sourced some 1 1/2" SS baffle tubing, it was only £13.00. It's also the same bore as the OE headers which I'm hoping will maintain some back pressure. Also it allows a bit more packing around the baffle, can't be doing too deafening! The 1 1/2" tubing (with a bit of flaring), sits real snug into the OE end caps.

 

[GUTZY]

Thanks for the pics. Post up some results from the exhaust mod when you get some.

 

[moto66]

No worries. Will do. I was going to start a thread like a build etc but I've been messing around with it on/off in no real hurry for ages! Cheers.
