ECU tuning for the RX3
 

Hello to all, I know a lot of you have been asking me for the PCHUD software to work with the Delphi MT05 EFI on these bikes. But I am here to let you know that there is a newer software out there that can be used with your newer computers operating system, 64 bit, and you can not only read your codes and clear them, but you can also edit your tune!
I am including a few pics from the ECU map of a 2017 RX3 to show you the mapping.

Here are a few more of the many different areas you can modify or adjust

having never tuned a bike before (decades of old school carbed bikes), what would this acheive or change on our efi RX3's? Please don't laugh at my ignorance. I typically have left my previous efi bikes stock in regards to tuning. This is wayyyy out of my knowledge realm, but am willing to learn a bit.

It could potentially remove any lean spots introduced by pollution regulations and/or any errors in tuning. There would have to be things to fix however, it's not like you can improve it if it's already correct. It's all about maintaining proper air/fuel ratios at all speeds and conditions.

Actually very good news. But, you'd need a dyno and an operator that knew the software and bike to get the best out of it. The stock map is supposedly really good but if at some point performance parts emerged this is a necessary tool.

So whats the "newer software" and where can it be found already... "nobody likes a tease" after all :hehe:

At this moment I have the red interface cable from China, is this program will work with this cable?

Can I change the Idle speed with this program?

You can change the idle speed, you can change the rpm limits, the Air fuel ratio, the bottom end fuel lean condition, idle air fuel control valve limits, timing, better mid range power, fix stalling problems, diagnose in more detail with codes showing that do not show up with generic readers. I have gone to a dealer who was only able to pull up one code. with this software I was able to pull up 7 different OBD 2 codes. I was able to clear codes the dealer could not. I was able to re-flash a 'faulty' ecu and it works fine now.

Yes in order to properly tune a motorcycle, you would need a dyno and someone who knows how to tune ECU's, but most dyno shops have those people around. They would just use this software to produce a tune for you. You would bring a laptop with the software in it, and let the dyno tuner use it to get the most out of your bike. You can copy and keep a stock flash in case you ever want to go back to the OEM tune. It does a lot, but yes, you would need to have someone who knows a little about ECU tuning with a dyno. I would check your local dyno service center and ask them what they would charge to use your software and tune your bike.

I will be selling the data adapter cables soon, I just ran out this week. they run $45. I sold out this week.

Ok this is looking good.

So if you have the cable + software + instructions I would like to buy this pack for my Zongshen RX3 ( Honley RX3)

Can you send to Europe ( London)?

Will it be reasonable to work up a tune on one bike at a specific altitude and then apply that to other bikes? I did a simple ECU add-on for my CBR1100XX that really helped. Once we did that on the dyno, others just used my settings. But it was a simpler mod that only added fuel at certain RPM, not a full tune.

If you need any other RX3 parts I can send to you also.
I’m keen to find out the cost of this tuning software as well but I’d say you need tech skills or you’ll go wrong easily

A friend's son sells these dynos to which you refer. He also teaches how to use and tune with dynos. Long history of very positive consequences. If you folks organize a class with enough students to make it worth his while I'm sure you would get your money out of it.

Price please
I’m keen

I have seen some significant improvements from dyno tuning other motorcycles. Specifically, Ducati and Guzzi had problems with surging, stalling, popping on decel and O2 ranging from rich to lean to rich again. With much effort those problems were eliminated but it took quite a bit of time both on the dyno and with some real time data logging (actually riding the bike while logging the ECU performance). If you have issues with how the RX3 runs this is a great solution. I don't. If you have done a significant mod to the drive train (big bore kit, exhaust, cams, etc) this is a great idea in order to get the most out of your bike. Mine is stock. For me the only reason to invest in the cable and software is to be able to trouble shoot my bike easier than trying to read the blinking code lights. Sooner or later I'll be faced with electrical or mechanical stuff that fails and being able to pinpoint exactly where the problem exists....priceless! Oh, and in almost every case the re-map resulted in lower miles per gallon.

Interested for my RX3, now that it has the big bore kit in it, I'm sure it would benefit from a tune

No idea. Probably significant. Seth is used to flying to Saudi 1st class twice a month to do 2 day schools. Can't get ahold of him at the moment--packing his family for a cross country location change. No idea why. Maybe he will need $$$$ after the move and work cheaper.

Is this BitBox software?
Can you supply or where can I buy the software? Can I use my red dongle for Delphi that I currently use with PCHUD or what hardware is needed?

I have find this Website

This would be really useful for tuning the bike after installing that 300cc piston kit... Somebody should make some maps for that and sell a re-flash service.

There are some flat spots in part of the throttle/RPM range that don't seem completely consistent, so I'd pay some reasonable cost to tune that out. Not sure if the 300 kit will make it worse, better, or nothing.

Having moved my bike from sea level to 1700-ish feet, should I try doing an ECU reset? I have those flat spots, and really can't hold even 70 on hills. I know, thinner air and all. I have a 13-tooth sprocket coming.

300 kit doesn't need or maybe you don't want the 13 tooth sprocket.
Most of the running issues in my experience is in the stepper motor being disrty ever so slightly and the nose of it needing a scrub as well as backing of the throttle so it closes fully.

Stepper motor and MAP/MAT sensors being the 2 main parts that I have replaced on several bikes, and CLEAN srub CLEAN the end and holes

AJP do it for their bike but you gotta send ecu in.
Actually I’d suggest new ecu and keep stock unit
I’d like to see if the poster can sell or share more info I’m happy to pay for knowledge but no reply

Might need to contact the Russians in that case :$

This is what they said I would need to buy - A lot for 1 bike lol

Sounds like you have a diagnostic tool only, so you need first a flash tool which can allow you to read and write the flash memory. For this you need BitBox dongle + BitBox Delphi MT05.x Module and Tactrix Openport 2.0 interface.

https://chiptuningshop.com/product/b...mt05-x-module/ - £225
https://chiptuningshop.com/product/t...-openport-2-0/ - £189

Once you have readout the maps from your ECU, you can edit them using BitEdit module and then write this data back to the ECU with BitBox. For editing you need BitEdit module:

My 300 kit runs well but it seems that it's exaggerated a couple pesky issues.
It still stalls when coming up to a stop, more so than before. Once it's totally hot, all is better. It just doesn't seem like the IAC is reacting quickly enough and I just cleaned both the tip and seat.
It used to be pipey with the 250 jug with almost no low-to-mid.
Now, it's acceptable on the low, excellent mid, then flattens out badly about 7+.
I do have a different muffler and cat-delete.

You may find the stepper is lazy and this seems to be a little common on Benneli bikes running the same setup, I had 1 stepper fail.
I get the odd POP on decel and with the mechanical stepper manual adjust it almost doesn't pop but seeing it is manual adjust the bike is crap when cold. it was an experiment and learning to see how n wait the stepper did or didn't do or was faulty in some way, manual adjust stepper coming out and recently replaced stepper going back in

So how would I go about getting software and a dongle to attach my motorcycle to read and/or adjust the map? My SSR Buccaneer has Delphi EFI, and I'd like to experiment with an open exhaust and a little extra fuel on top.

Charles.

Only live data
No map tuning

Okay. But still... how?

Are you in need of the cable software and adaptor plug for your bike? Is that what you mean?
I source and sell parts from China and I have the cable, an XP laptop and Katflaps version of software (that software I will share free no money if you needed it with a cable etc)

Right. I need to know where to buy the cable and adapter plug, and where to download or buy the software. :)

Hrm... if you source and sell parts from China, is it possible to get bits from the Italjet Buccaneer 250i? Motor-x.com sells a bunch of interesting OEM parts, but they don't ship to the USA. There are quite a few pieces I'd like to buy... especially region-specific parts that aren't available from the US distributor SSR.

Charles.

PLZ check my last post

That bike is sold here but doubt there's much aftermarket like on the site you asked about.
China is a funny place.
INFO is what I need etc

so you sell the connector for the Buccaneer 250 to be able to tune it?

I do not know anyone that tunes the Delphi EFI

Maybe that bitbox.co.uk or the Russians etc.
Scanner/code reader YES that is fairly easy but changing MAP or tuning NO sorry I don't have any correct knowladge
