TuneECU tuneup guide for dummies

[CrackaNMC]

Anyone keen on writing up a TuneECU tuneup guide for dummies? Id kick in some coin and Im sure other would to.

Looks like there are lots of things to learn about before even going to the fuel maps.

I started at "where is the ECU connection"

Other things like
the make up of the ECU (eg: F vs L and ignition tables I1=neutral I2=1st gear, etc)
quick guide for enhancing performance before adding on pipes or intake mods (eg: secondary butterflies and ignition retardation on 1st and 2nd gears)
what the 12 minute tuneup does for the bike

I think all this info and so much more is around and needs a guru or gurus to sort it into a single useful guide.

Just a suggestion.

Also can the TuneECU guys add and option to overlay the closed and open loops on the maps. just a simple line drawing. have this option on ECMSpy for Buells. Actually ECMSpy has a lot of useful features they might want to have a look at.

Thanks to everyone who has already shared their hard earned knowledge and software with the rest of us. Im glad I dont have to install a power comander.

The Keihin ECU uses a narrow band Lambda sensor, as a result, it is always in open loop - never closed loop. Even adding a wideband Lambda unit like the LC-1 from Innovate, or others, that will log, etc., cannot make the stock ECU operate in closed loop without some very creative software work in the ECU, and new inputs for a wideband sensor.

Even with such software, the ECU would only be in closed loop operation at idle and cruise. Many prefer to tune or have their bike tuned and not run at true stoichiometric ratios (Lambda 1/ 14.57:1 AFR) at these points for improved idle and cruise characteristics.

The ECU interface connector is under the seat, tucked face-down along the left side near the frame. It is a standard OBDII connector, just like all modern cars use.

If you read through the TuneEdit/TuneBoy tutorials and the basic "how to" threads on this site, you will get a good grasp of what TuneECU does, and how it operates. Tom Hamburg has written a nice multi language introductory user's guide to TuneECU as well - Overview

There are many threads on what the "12 minute tune-up" does, and how to perform it.

If you do some searching and reading on this and other sites, you can get a good grasp of basic tuning with tuning solutions like TuneECU and TuneEdit (very similar).

TuneECU has only been available for a few weeks - it is still evolving. Give the developer and users some time to work out a few issues, and you will likely see a good amount of information and supporting software applications for it.

pardon me for going slighty O/T but when is it suitable to have a wideband O2 sensor, only in conjunction with a PCIII?
I trust you completely but I have read several statements about the ECU being in closed loop a majority of running time, cruise taht is of course, not acceleration.

No need to burn me guys Ive done a heap of reasearch and reading

As I said in my post all the info is around if you want to do the research but TuneECU being such a nice new product could use some help from the community in collating all that info into one place.

After all the software has been given out for free by the developer (at this stage anyway) and he is going flat out making it awesome for us the least we can do is help him out with some doco.
