Dyno and road simulation ideas and suggestions

So I am getting to the stage in my EFI build where I should have the bike idling by the end of this month and after I establish that I will be obviously trying to finalize a few things like airbox dimensions and fast idle actuator. After that I will basically need to tune the bike under load.

Now I am a cheap bastard.
Up until now I have done quite well vs my budget on this project so I am pleased in that regard. However I either need to road tune the bike (which I think by the time I have everything finalized we will be late into the summer and I made the financial decision not to ride in favour of purchasing a house this year. So there is no insurance on the bike so road tuning is out. That leaves dyno tuning. Now I know this gets fairly expensive and add to the mix the fact that most tuners use power commanders and stuff they may not be familiar with tuning on a micro/megasquirt which adds to the problem. What options would I have to tune it myself in my garage? Can I put a load on the engine in a non-conventional way? Perhaps using a brake to load up the engine.

Or is there a dyno shop that is maybe not too expensive? Would it be unreasonable to expect a map for say $300? Especially if I have an O2 sensor already hooked up there?

Any thoughts or something I may not have considered?

Let's hear it.
 
It is going to be A LOT more than $300 to properly map an EFI system. I've been working on my own Power Commander map since last August and I'm *still* making changes whenever a situation occurs that I have not encountered before (the hot weather in the last few days is one of those things).

Get a wide-band air/fuel gauge and mount it on the bike in a place where you can see it while riding ... you're going to need it!

You will be able to do the no-load line from idle to redline without loading the engine.
