Buy the way great website,thought I should finally join.I have a question about the pim.My r450 has a full yoshi,cb,ehs racing lid,and am running vpms103 racing fuel.As we all know we can never get a consistent answer from yoshi!I have the pim sitting in my shed unopened because I am unsure if I really need it or not.Does anyone know yet if the map installed with the pim for no spark arrester is the same as the map that the cherry bomb enables with the stock ecu???Just don"t want to waste the time or money installing the pim if i don't really need it.Any replies would be helpfull.Thanks!!

Good question ?
Anybody !

From my understanding the PIM and the Cherry bomb have the same map installed. The Cherrybomb just uses the race map in the factory computer and the PIM has the same exact map installed in its own memory bank. I will not deal with Yoshi if the two maps truley are the same. The only way to find out is to call Yoshi and find out but GOOD LUCK with getting a straight answer. I would like to see a back to back dyno run with the Cherrybomb then the PIM.

Funny you should ask. I have the following email going out to Yoshi Tomorrow!

First off thanks for getting me out one of the first batches guys but I have a few questions.

As far as the FIMAK and PIM goes can I also take the program you have available for download and use my notebook computer to program the ECU? If not, do you plan on making this option available in the near future? This option would be an excellent thing to add if the ability is not there right now. As the PIM already has the proper port it shouldn't be hard to come up with a simple program that will access the ECU and be able to interact with it. Thinking in this direction it would be better if Yoshi came up with the program rather than a 3rd party.

2nd for my own edification I have a few questions.

First off could you please send me in PDF format the two stock maps that are in the ECU as I would like to know what the stock two maps are in the ECU and how they compare to the 2 maps in the PIM? Of course this is assuming that the CRBM map and the 1st map in the PIM differ. You can see where I'm going here. I really would like to know what maps are being used with various setups.

Secondly could you please explain to me what is happening when I program the ECU with the FIMAK?

a. Am I overwriting the two stock maps? If not, what am I overwriting and where is it stored?
b. Is there any problem with programming 2 maps thus giving the ability to switch between the two maps by putting in the shunt?


Thirdly could you tell me what the db level of the Yoshi Pipe is with and without the spark arrestor and do you currently or are you planning to make a quiet core that will lower the decibel rating of the Yoshi for the LTR to 93 or below?


I am asking these question because I belong to a few technical sites that deal with the new LTR and many individuals have the same question. If I can find some answers it will help me put out the correct information and possibly result in cutting down on the amount of technical questions you get in reference to the PIM, FIMAK and CRBM.

Your help in this matter is greatly appreciated.

PIM all the way.

OK I got some answers from Yoshi. I decided to go ahead and call them. I spoke with Demond in Technical Support.

First off the two maps that are built into the LTR are the stock map and a Motocross map. When you plug in the CRBM it activates the motorcross map. Now when you hook up the PIM with the Yoshi it puts in an even more aggressive map for both the spark arrestor setup as well as the one without the spark arrestor. So the maps are different with the PIM than with just the CRBM. I asked him specifically if the CRBM map was the same as one of the PIM maps as someone from Yoshi had told an individual that one was. His answer was no and whoever told that individual that was wrong and it would be stupid for them to do that. As to what the two base maps are (data or MAP wise) that are in the stock LTR he can't answer that and doesn't see them getting the info any time soon. By programming through the PIM you are overwriting the two base maps that are already in the bike.

As far as being able to use their software and hooking up your laptop and programming the ECU through the PIM he said that's not possible and they are not working on any such program. I still believe this can be hacked by the right person. I may know that person and may have him try it.

As to the db level of the Yoshi it's 92-96 with the spark arrestor and 96-105 without it.

Brand new RS-5 with CB, checked by WORCS official this past weekend was 98.7dbs with sparky. Some passed the sound check without sparky (101dbs was the limit)
