No more tuning CB1100??

[gretle_2.0]

The hard work has already been done- the tuning.

What we need is a way to pull an existing file from a tuned ecu and write it to other ecu. Cloning.

Probably can be done with an existing tool / cable / software if anyone was interested enough to dig around the internet.

Hmmm indeed. Will it still be safe to run a full exhaust with no tune? I guess my only option would be to buy a ecu from a 2013 CB1100 that already has Guhl’s flash which I don’t think maybe people would do unless they were selling their bike and wanted to put the stock tune on it.

I wouldn't take the cat out without adding fuel in some way.

Others have I am sure... and yea it will 'run' but leaner /hotter than it should- and Honda already had enough issues with engine heat failures on this bike in the design process as is.

Yeah I just called a local place to me and they’re able to flash my ecu and dyno tune it. Karns Performance in Mechanicsburg, PA. Now before I get tuned with a full exhaust is the TSR intake mod really worth it?

I'll have to look up that shop- to my knowledge Guhl was the only place that had cracked our ECU to be able to bench flash.

Which TSR part are you referring to?

There is a simple TSR plate that replaces the intake snorkel on the airbox- it only makes about 2whp at the VERY top of the RPM.

I dyno tested it back to back- and since it made very little power, and made an intake noise that I didn't like, I did this now instead-

Then there are the the TSR velocity stacks that replace the stock ones in the airbox- they will make good power, but I don't know if they are still available, and they were expensive.

I would suggest this instead- https://cb1100forum.com/forum/showthread.php?tid=10300

Those modified stock velocity stacks have flowed enough air that I have made 103whp and 75wtq so far.


And lastly- right now I am in the middle of installing a new dual height velocity stacks I had custom made-

Yeah I meant the intake air box mod. So the velocity stacks are doing worth while I guess it seems to gain a substantial amount of power? And thanks for the links! And that’s awesome! Love your DIY stuff and I can understand for the most part because I went for Mechanical Engineering, what software did you use for the flow of the them? Only software I have used for that is Siemens Star CCM+

I didn't do the computer simulation stuff- that was done by the shop I hired to make the stacks.

Oh my mistake, Awww what are your expectations power wise for it?

Whoops didn’t mean “Awww” there lol

So..... why did Guhl stop tuning but Superbike Unlimited, VCycleNut, Ivan and everybody else still tune/flash ECU's? I'm rather confused....

He may have already been approached by the EPA and they haven't yet.

Or he may not want to take the risk of massive fines.
