Hi everybody,
One of the things that I decided to do when I commenced installing this turbo kit into the bike was to tell people the steps that I took so that we can remove the smoke and mirrors around installing a turbo into the bike.
The first stage for me was to give the bike a brain transplant. There are two routes you can go with a turbo, one path is with an FMU like the Ghetto kit which is like a regulator that increases fuel pressure with boost pressure, so the stock injectors can flow more into the cylinders. This method also requires an PC2 or PC3 to adjust fuelling. The other path, which I have taken is to put an aftermarket ECU into the bike and increase the size of the injectors. The stock injectors are 225cc and will give up the ghost at around 190hp in a forced induction application. In the future I will fit injectors of around 400cc into the bike.
The ECU used is S&R Pro's TSI unit. This is a very powerful tool which gives you absolute control over almost every aspect of the engine management system. To fit this unit required about 14 connections to be made into the wiring loom of the bike. Needless to say you're pretty worried at this point because your cutting wires that will mean the pride and joy wont run if you screw it up. So it's a deep breath then get snipping.
This is all the wires connected in to the loom and the re looming underway. I located the TSI on the left hand side of the bike in front of the reg/rec under the rear seat. This will leave room for the water tank and the water injection system to come later. Pre planning the job is important as you can see.
Here you can see the TSI in the lower centre of the screen, look for the cable ties and you've found it. The TSI unit here is connected via a 9 pin serial cable to my computer so that mapping could commence.
Here is the PC fired up and ready to commence mapping. The advantage of the TSI unit over the PC2-3 or the Yosh box is that the tuning of the engine is live. When you make a change on the PC you make a change on the computer. I found that the TSI did not have a zero map in it so when I fired the beast into life there was a huge cloud of black smoke then the motor died.
So I saved what was in the ECU into my PC, then zeroed the whole map. This involved setting all the fuelling, ignition, TPS (Throttle Position Sensor) etc to zero and mapping the bike from the TPS. Success, she fired into life and ran as it did before, and above is the screen shot of it doing that.
Now I need to get the bike mapped for the TSI and then we are good to go. That will give me a map that is good for a naturally aspirated bike. This can then be evolved as the turbo application is applied.
