700 Fuel Injected Engine

[SandShots]

My buddy just got a Raptor700 and is looking to slap on a full exaust system.

Does the computer of a fuel injected engine pick up the mods done and compensate on its own, or does the computer need to be reprogrammed by the stealership?

others have to be programed, i'm sure the rappy is the same, maybe somebody else will chime in?

I have a Griz 700 and it needs to be remapped with a programmer.

I would assume that you need to have it reprogrammed. Im sure that they will change the injector duty cycle or pulse width to richen up the mixture. You should also be able to change the timing curve as well. I am curious if anyone knows exactly how on injected bikes.

Remap the cdi/ efi ecm.

To change the AF (air/fuel) ratio, you need to install a Power Commander between the ECU and the injector(s) as well as remap. All modern sport bikes are FI and use this system. The best way to get max performance is to dyno and remap at the same time. It is an involved process but waaay more accurate than a carb can ever be. Here is a link to your particular application:

My '05 ZX10r dynoed at 167.5 Hp at the rear wheel....woohoo!!

 

Dynojet, the manufacturers of Power Cammander also offer free base maps that are somewhat OK, but as all of us that jet know...every bike wants it's own particular jetting.

 

Getting off track...There 'ya go!!

I don't think with the stock programming that it will compensate even if you take just the air box lid off. The Dynojet programmer seems to be the best one that i've seen on the market. They have tons of mapping that you can download. They have pretty much any combo of mods you can think of with a fuel map to match. Or you can make your own maps for it as well. As for other programmers you can only adjust low, mid, high rpms. Thats the only adjustment they give you on them.

On Raptor 700s you dont HAVE to program the EFI after installing a pipe, but to get the full benefit from the pipe you should. At least thats what ive been told. I know on a stock one you can gain a bunch of power from just a programmer. Im gonna get one sometime soon for my rappy.
