Reputable dyno tuning in Htown?

Hey guys,

I've been tossing the idea around of installing a PC5 in my 13' and I want to bring it to a dyno in town.

What are the most recommended and reputable dyno joints in Htown?

Just get a Bazzaz ZFI and add the AFM. Ride the bike, plug in your windows based lap top, retrieve, select all and apply. You can do this every time the weather changes dramatically. You can even add a map select switch and build 2 maps. One for summer and one for Houston's other one season. I had one for pump gas for track days and the other mapped for MR12.

They'll walk you through the process if it sounds daunting. Their customer service is second to none and they wont nickle and dime you if you break something.

I asked a reputable engine builder about putting my BMW on a dyno. He could have easily taken a few hundred bucks from me but he told me that with the AFM I should just save my money as he probably wouldnt get much more out of my stock motor.

When you're done take the Auto Tune off and save it for your next bike.

The auto tune is the best way to go unless your going to dyno and re-map as the weather changes and you switch between pump and race fuel. The map required from one week ago until today is very different. Why not have a continually updated "dyno" map every time you ride. The dyno is only as good as the dude running it on that day. As long as cdill35 consistently beats Guthrie at the races I stand by his opinion.

I'm very interested in this topic as well. The research I've done so far recommends that even with both these recommended routes you should do an initial dyno to find the best Air/Fuel Ratio for your machine and it's environment, then allow these 2 products to fine tune.

Is this not true/needed?

There is still no need to dyno for weather. The auto tune will handle that too and you can store 2 maps for fuels

Patrick and Bill (bd270) probably know better than I (and probably bluewave), but I have never put a motorcycle on the dyno. I just practice for 40 minutes the morning of the race, retrieve and apply the percentages after each session and get after it.

You can set a target ratio in the program. I dont remember what mine was but I wanna say 13. I guess a dyno could find the "perfect" target I guess if you're trying to squeeze a bit more out of it.

I have tuned with auto tune too many times to count. I was making constant changes and adding parts like nitrous. I decided auto tune was a must after numerous trips to dyno inside of a year. I even went to dyno once to verify the tuner was doing its job. There were no changes that the tuner could find that would benefit me over what the auto tune had done. It managed changes like cam, heads, bore to 1441, nitrous pill changes, ect. I just added fuel to the base and let it lean it out. I had to be pig rich from the start to be safe. I did combos of street tuning and drag strip tuning. Make a pass and accept its recommended changes and repeat. You set a target AFR and it sniffs and recommends the changes it thinks you need to get there
My bazzaz was wired to a relay. When the nitrous solenoid fired, it triggered a relay which triggered my map change to the nitrous map. You can switch between maps with the flip of a switch or rig a pig tail to ground the 2 terminals

Please excuse my ignorance, but even when changing fuels(street to race/other) a change in AFR is not needed?

Different fuels can cause a different afr. You adjust tune to maintain a target afr. Oxy fuels will change it for sure

So how do you know what AFR to use without a dyno? Or do certain fuels have a known AFR to target?

Depends on build. 11.5:1 to 12.5;1 is a normal target. On nitrous I ran at 10.5 to 1. Fat is safe and lean is mean. Lol

Very interesting! Sorry to bog down on clarity, but your 11.5:1 to 12.5:1 is that for street fuel or race fuel? Or is there not much difference in AFR between those 2 fuels?

It's not based on which fuel. Different fuels have different burn characteristics that may require more or less fuel to reach the same afr in a given engine. Oxygenated fuels add power but due to the oxygen content they lean the mix out and need more fuel added to compensate. Result is more o2 and ability to burn more fuel. That's how bit makes more power other fuels are used to reduced detonation like in a high compression engine

What a dyno can tell you on paper is what afr your bike likes and makes peak hp. Different motor combos like different afrs. Now, remember what I said, on paper...the track may say different. All the dyno is, is a tool to get you close. Like everyone stated, it (density altitude) changes throughout the day all day, everyday and this is what causes a bike to slow down or speed up

But if you want to dyno it, for a bike, Johnny Cheese is very good. Freddy at Eastside honda knows his also. Andy would be my choice if it were a European bike
