ALL TR650's NEED THIS - Introducing the ERUPTION!!!

[foxracer74]

Thanks for the info guys. I plan on ordering the parts over the next couple days and I'll have to contact Dan also. I want to get heated grips and gear to ride in these extreme temperatures.

Dyno results.

Green is stock AIT, air filter mod and custom single exhaust
Red is Eruption and air filter mod and custom single exhaust
Blue is Eruption and air filter mod and baffle out.

I did a 6 k rpm run and our bikes run fat at that rpm.

Were you also checking the air/fuel ratio? Seems lean down low.
The '650 has its max power rating at 7,250rev/min and max torque at 5,750rev/min. Definitely changed its performance with your mods. Better mid range for commuting.

 

[mag00]

One of the reasons for this run was to check the air/fuel. I have been chatting with the Steve and Roger with the AF XIED O2 mod.

Both insist that the bike is to run rich at full throttle, so I ran the 6k, to see if on a non full throttle it was still rich, and it is. Phil at ESP, who did the dyno test confirmed that it was way rich even for full throttle on the higher end.

Also, talking with Stephan at hexcode (gs911) The AF XIED that works on the BMW F800 apparently works on the Terra. (Ask Qurky)

Originally I was going to go after an O2 spoof. With the fact that my bike runs rich at higher RPM, I am apprehensive of running the AIT spoofers or any spoof that doesn't compensate for the richness at higher RPM's. I have been chatting in a couple different places about designing a mod that will do both enrich at low, and lean at high. The PC5 does, @$600 or so.

Originally I was designing based on a wide band O2, and thought I had a solution, but turns out the TR uses a narrow band O2 and the game changed. I have two separate companies that will assist in the circuit design, at a price. Two separate semiconductor companies have offered sample chips. I just really need to sit down with an O scope and some nerds and get this designed. In the meanwhile, I may or may not run the Eruption, as my bike does OK without the Eruption.

Next tankful I will run with the Eruption and see how it affects my mileage. One thing I would like to mention is that my bike has dropped MPG just by ambient air temp dropping. Most of my great mileage was in 100º temps. The last couple rides have been around 80º or so. (sorry cold weather friends, you can keep your snow).

Hi Mag00,

I see you have been talking to Roger about the AF-Xied. Have you seen his research that suggests that AIT spoofers are quickly adapted out by the BMW/Bosch ECU's?

Just bought a Strada, aaaaaand it stalls out all the time, even after a MOSS session. So, the question is: is there any reason why a guy would want to buy a Power Commander with Auto Tune instead of just doing the Eruption mod? Aside from the obvious cost considerations, is there anything significant the PCV does that the Eruption does not, such as adjusting for leanness on the top end?

Thanks!

 

[Nick780]

Installed the eruption and fully happy with the difference made.
I'm up in Canada ans it's still a little cold here. When the CEL came on I wasn't surprised BUT when my comes on the temp. readout goes blank with --- three dashes instead. Does this occur to others?
I'm starting to wonder if one of the leads is making intermittent connection as the readout does this inconsistently.

PCAT is a more precise tune of AF than any passive spoofer is going to be. IIRC the bike may actually run rich on the top end so a PCAT should address that. Some reported difficulty with early PC installs on the TR but some like DBrider report great results.

Sorry can't give a direct answer, it doesn't get very cold here in Long Beach.

If temp readout on dash goes blank inconsistently & inconsistently is defined as regardless of what the outside temperature is, then you may have something loose. Generally a loose connection would become evident as you ride - the display may go blank along with bumps & jarring.

For a test you can do this;

Pull the IAT connect it to a VOM (voltage ohm meter) , verify R/T (resistance measured at a specific temperature, use charts in OP) wiggle, tug & generally molest it a bit while looking at your VOM if resistance stays the same then your connections seem to be good. If resistance suddenly changes (but not as a result of your body temperature touching the IAT) you may have a loose lead (wire) somewhere in your build. Also you can go back to an OEM IAT to compare.

Hope that helps.

I just thought I would mention that can use 4 50kOhm thermistors, probably more manageable than 8 100kOhm. You could use 2 25kOhm thermistors if you could find ones with less than 2% tolerance.

I'm still very happy with the Eruption mod on mine. Made a huge difference stock and it kept on giving excellent results after I went to a full, no cat single silencer GPR system.
Just remember to give the ECM a little time to adjust things.

Yeah, I have a few emails too, from both of them. I'm tempted to try it. I have the Eruption, and it did add some performance as seen in the dyno chart. I wonder if the AF xied would be similar. I would like my ait to read proper on the dash.

I do not think the bike will correct for the temp. As far as the ecu is concerned it is cold out, and reads the map for that parameter. No adjustment by the ecu needed. Initially I thought it might.

Think if you only drove in the arctic or some cold climate. It would just run rich all the time, as set forth by the map. If the ecu corrected, the bike would start to run like junk.

I may try a wuka, as I bought one awhile back. I like the idea of two position offset. I may not need the full 35 degree offset to run great. The second position could make a difference for me in traffic in the heat. Don't really know until I plug it in.

A very interesting mod, run-it. Well documented.

I'll be having a look at the IAT on my TE449.
I assume it'll be different (It runs Keihin injection, also tuned lean by BM-Trouble-you), but the mod might work for it just the same.
A bit of time in the shed with the multimeter coming up again

If it has an IAT & they used a 5kNTC thermistor in it - the mod should work.

It has an IAT, not sure on the values yet as I'm away for work, but I'll be sure to test it over Easter when I'm home.
I thought a fair bit about it last night, if it has the sensor in the system, it must have corrections in the mapping, otherwise why have it?
What brand ECUs do the TR650s run? The TE449 is Keihin.

I'm keen, thanks for the idea. This is where forums are great

 

[Baddrapp]

For the TE449 the JD Tuners are reported to work good. But the PCV with the auto tune is suppose to be the best. Zip Ty Racing has the best maps for the PCV's and then the auto tune adjusts it for each bike. JD does not have anything for the BMW's.

Magnetti Marelli for ECU in the TR.

But ECU type won't stop you from trying, worse case it will only mitigate the full positive effect , the 5kNTC is key, if you don't have that - the mod won't work.

 

[Dangermouse449]

Well aware of the good things the PCVs do for TE449/511 bikes.

I'm content fiddling with my standard system more as a challenge

Hey AJ good thought but owing to the non-linear R/T curve it isn't going to be as accurate as the 8-100kNTC.

You can plot those out using the mfr specs for resistance at 0 & 50C then compare to our targets & you'll see what I mean.

 

[Lekolite]

I just did the Eruption on my bike. It ran great on my first outing. About 2 hours on twisty mountain roads. The acceleration seemed much smoother. Also did canisterectomy as well.
