Power Commander Tuning Tips?

feeds@yuku.com (RussMcB) — Fri, 30 Oct 2009 10:00:46 GMT

I'm taking my F1000 with '07 ZX-10R to the chassis dyno tonight. I have what I think is a good basic plan (see below), but looking for any advice. I've practiced making fuel map changes in my garage, but this will be my first time tuning a Power Commander for real.

I'm anticipating 5-10 runs. The first three will be to determine which map I will use as a starting point. The three I have chosen are the custom map that came with this used PCIII (I ran it at Barber,...

fuel leak

feeds@yuku.com (herman pahls) — Thu, 29 Oct 2009 00:55:31 GMT

I was very fortunate to get by without incident with a serious fuel leak.
GDRE cleaned all 8 injectors and I inadvertantly damaged an O-ring replacing one of them.
I did not lubricate the o-rings which I now know to do.
I drove the car 60 miles on Sat. and it ran great.
Sunday I started the engine before climbing in for a drive and was greeted with a 50 psi leak.
Why it did not leak the day before????

I am not able to find a 10 micron compact inline...

NEW DESIGN MUFFLERS

feeds@yuku.com (DOLeary) — Tue, 27 Oct 2009 09:39:35 GMT

Does anyone have a supplier for the new cone design mufflers ?
Does anyone have a idea if it helps HP.
Cost?

Fuel pressure

feeds@yuku.com (herman pahls) — Sun, 25 Oct 2009 00:58:31 GMT

Does anyone monitor fuel pressure on their data logger?
Above 7000 rpm my fuel pressure drops from 50 to 42 psi (mechanical guage) in the higher gears on a 2008 Hayabusa.
GDRE felt that there should be very little if any pressure drop on an adequte fuel system regardless of load.
I am using a Mallory pressure regulator and just installed a new Bosch fuel pump and got the same pressure drop.
I am trying to solve a severe miss the engine developed above 7000 rpm at T-hill...

dry sump tank size?

feeds@yuku.com (924RACR) — Fri, 23 Oct 2009 10:04:06 GMT

Any comments out there on the appropriate capacity for a dry sump oil tank for our 1000's? Seems like many of the tanks out there would be sized for car motors, and a little on the generous size?

Hotter Oil

feeds@yuku.com (herman pahls) — Wed, 21 Oct 2009 03:09:59 GMT

I did a track-day at T-Hill last Sunday. 70 degrees F and humid. Redline 10-40 racing oil.
I let the stock 2008 Haysbusa idle for 20 minutes before each session and oil temp would only get to 130 degrees.
What should the oil temp get to before full throttle is used? Highest temp. after session was 180 degrees.
I used the same cooler with the previous 954 Honda and temp would get above 160 after 10 minute idle and max. at 230 degrees under similar conditions.
Any...

R1 engine oiling system

feeds@yuku.com (Sam) — Fri, 16 Oct 2009 11:39:50 GMT

Hello, i found an engine for my project.
I get a Yamaha R1 2004 (so the injection model) with less then 10000 kms on the clock.
Now i would like to know from you experienced guys if with this engine a baffle plate in the sump is sufficent or if you think installing an accusump as well would be needed.
In a case of the accusump , how can i connect it to the engine?
The R1 has an internal oil cooler, so i cannot connect it to that line because there isn't .
The...

Radiator size

feeds@yuku.com (kiwimanz) — Wed, 14 Oct 2009 11:41:33 GMT

Does any one have an opinion of what radiator and oil cooler sizes are needed to cool down an 08 GSXR motor?
I'm ducting from the top on the body ala Stohr's method?
Thank you

good or bad Idea for engine mounting

feeds@yuku.com (Sam) — Mon, 12 Oct 2009 12:06:58 GMT

Hello, i just want to ask if anybody could help me out with my "new" idea
I thought about installing the bike engine rotated 90 degrees into my chassis so the drive sprocket is facing to the back of the car.
Then i would machine a special adapter with which i could connect the drive sprocket directly to a rear wheel drive car differential like for example the one of a BMW .
In that case i would not have a chain drive and no chain tension adjustment to be done.
As...

Power Commander PC5 w/Auto tune

feeds@yuku.com (kiwimanz) — Sun, 11 Oct 2009 20:40:19 GMT

Hi there, has anyone tried using one of the new PC5's on their motor? I'm planning on hooking one up with the auto tune system but I'd like to hear from someone that has tried it.
Cheers

Who sells these parts

feeds@yuku.com (Daryl Brightwell) — Sun, 11 Oct 2009 14:37:24 GMT

I need to find either new or used parts that match my other 2000/2001 R1 engine, two oil adapters and the oil pan. Here are photos of them. The pan is holding me up bad right now.
