[HOW TO] Tune and Modify IAW15P ECU!

[Woflow]

Hi I tried the Reader on FSR 450 '07 , it works fine! Thank you MercyFlush!
The most difficult part is finding information and getting knowledge about modifying the mapping.

why are there two fuel maps/ignition maps? Because of the blue/yellow wire connetor? How do you realized the map switch?

Do you want my rom file for comparison? I'm not sure if its stock, because i've bought my bike with an unique handmade exhaust, maybe it got an mapupdate.

Communication cable:

KKL 409 cable + Fiat connector


This set should work:
for example: ebay

I'd LOVE your Map, It's good to see someone else have success with the program . If you can upload it to dropbox or something that'd be great, or even to the forum if it's allowed (just rename the file to a .txt instead of .bin to upload on the forum )

The reason they have two maps is generally so that the bike can meet local emissions laws but also have a way of going into a 'race' tune. I'm using this as more of a cruse map for the highway and a more enriched tune for the bush etc. The issue is that the bike's ECU is Open Loop which means on constant loading you'll have issues with running too lean/rich.

Now comes part two of the [How To]. I'll put the update of opening and modifying a rom.
As I was saying in my OP, I've not got enough time to go through step by step, but I'll try to put as much detail in as I can. I'd be great for some other people to share the workload as it'd be nice to be able to get our bikes all nice and tuned up!

As I was saying in my O.P
"The general solution is to buy a USB OBD *type* connector along with a FIAT 3 pin connector. You MUST insure you purchase a cable with an FTDI FT232R or EQUIVALENT serial converter inside and the OBD cable MUST ONLY do level conversion (It must NOT have a ELM327 controller). The OBD cable must be a K-Line or ISO9141 etc. compatible. You *can* make your own cable (I did) but just buy the damn thing trust me, it?ll be worth it."

So yeah the above cable will work IF it has an FTDI chip in it. It MUST be an FTDI chip otherwise it's just plain old not going to work. I had bought three VAG-COM cables each time they have a different chip in them. I ended up making my own by substituting the prolific chip with an FTDI one.

Here is my map: https://dl.dropboxusercontent.com/u/...SR07_stock.bin

I bought today an ecu from 400 FSE. On next week I will upload the map to.

I will try some edititing on this ecu.

Does everybody know something about "Rexxer-Mapping" ?

Very nice, thanks for that. Here is a link to my bin (I didn't realised I hadn't linked it earlier!)

I wouldn't worry about the rexxer stuff. As far as I'm aware it's just an auxiliary box that overrides the fuel injection and ignition timing of the bike similar to the power commanders etc.

What we have is FULL control over the bike's ACTUAL ECU. This means we can map it in whatever form we wish. You can even add in additional code, but this is something that I'll have to get into in a later post as it's not something I can quickly type up. To map your bike first you need to make sure you've correctly located the fuel and ignition tables. If the graphs look odd then the hex offsets are incorrect and must be adjusted. I'll have a look over your ROM when I get a chance (probably in a few days on the weekend). Pretty much the fuel and ignition tables will be in close proximity to where they were on my bike, so I'd suggest shifting the offset address forwards and back until you've found the limits of the map etc.

Great to see you've made good progress! I hope others do too!

Unfortunately for me my gases died yesterday. I was riding home from getting some parts to fix my car and the gearbox started crunching. pretty much every gear but 4th was making an odd grinding noise. Hopefully I can have it rebuilt before the new year, but chances are it's not going to happen

If you're going to start messing with your fuel maps I HIGHLY suggest you buy and install a wideband oxygen sensor. Without this you will not know for sure what AFR's you're hitting. The last thing you want is either the bike running extremely rich which destroys your fuel eco, or running extremely lean causing insane exhaust temps. the wideband will give you a good reading on what's going on

EDIT:
Here is Bernd's XDF corrected to work with your 2007 FSR450

Hallo. How we can make map switch on my 450fse 2003. I cant found blue/yellow wire. All what I can is read and write new map but how change when ride. thx Kamil

Hello, I'm still working on that. 2005 onwards have the dual map switch but I'm going to try and add it in to my bike when I get time. For now you have to rely on manual changing the map and reuploading it etc.

I'm actually just finishing a full rebuild of my 2003 and once it's finished I'll be getting right back into this and finishing the tutorial

hi.can yomeone explain me what is the difference between the e-g and m versions of the iaw15p? which one is the latest?also are there any hardware differences?
thanks

Nice a very late reply on this thread.

Having seen all the posts and replies on the Guzzidiag / ECU tuning/ TPS reset questions, allmost everything is clear.
the only thing is, Where do I hook the cable up on the bike? Is there an interface, or do I have to tap off somewhere?
PLease help, as my FSE 450 2005 sometimes dies when hot and I hve no clue how to diagnose this at the moment

Edit:
found the connector, I can hook it up. whoohoo.
Now the known issue of "file does not fit your ECU"

Will contact the master
