L3 dyno tune

Bike has m4 gp full titanium system, K&N air filter, ECU flash, PCV w/ secondary and ignition module.

Blue, 165 hp is with ecu flash and crappy PCV (primary only) map 93 octane pump gas.
Red, 185 hp is after remap on primary, secondary and ignition modules.
Green, 195HP is with VP MR12 race fuel.


Tuning was done by Eric Lee at proven power in tampa.

There was persistent sputtering at 4000-6000 rpm. He suspects plugs are the cause since it did it in the stock B and C maps which were untouched by the ECU flash and no amount of adjustments in any of the power commander maps would stop it from happening. I'm going to throw a new set of plugs in tomorrow and see if it goes away.

Let me be the first to call bullshit on a 30rwhp gain from a tune and an MR12 map. Congrats. :facepalm

Holy hell, I need to go to your tuner!

:facepalm

Talk about inflated dyno numbers.
 
#15 ·
I don't know a bunch about dynos. How would one inflate a dyno to read 20 hp more from tune to tune, on the same day, at the same temps and on the same fuel all without going into any menus and changing settings? Then after draining the 93 octane fuel and filling with MR12, gaining 10hp (exactly what you would expect from the fuel change).

Please break that down for me.

Can he also deflate your dyno numbers to read the same as a 600?

:lmao

Guy had just done a s1000rr and it made just a bit less power. Same dyne. :dunno

Unless there is some hidden switch somewhere I don't understand how he could make it read higher. I sat there and watched him the whole time and I never saw him go into any menus and change anything on the dyno.

What year was the s100rr? If it's new as well I'm calling bullshit.


Oh wait this is polkgixxer I'm calling bullshit on everything that comes from you.

I have a question why didn't you have it detuned to a 600 since it's possible and all?
 
#14 ·
Did you have this sputtering before you took it to the dyno?

By using different correction factors, or by using a low number run as your baseline.

I am saying there is no way you gained 30rwhp just through tuning and fuel, unless your first map was so far off that the bike couldn't have even run properly.
 
#18 · (Edited)
How do you change the correction factor? I was standing right there and never saw him go into any menu a change anything like that.

How do you use a "low number as a baseline"? Low number was with the map from the guy in Kissimmee. Warmed up bike, fans blowing, same fuel, full throttle. Where/how does one introduce less horsepower under those conditions with the bikes owner standing 12" away from you watching the same screens?

Not saying your wrong. I'm just trying to understand where the slight of hand was.

Also, the bike WASN'T running properly, and hasn't been since the exhaust and ECU flash. So, the bike was only making 145hp when I brought it in (20 hp below claimed HP) and he simply brought it back up to 165hp and his dyno just reads 20 high?

This dude is a very successful troll....

Point me in the direction of the last troll-thread i have started please...

Does anyone know of any shops in Florida (preferably central Florida) that have the woolich racing ecu system? I'd like to have it tuned through the ecu rather the the PCV if possible to get rid of these FI codes.
 
#32 ·
That's what the MoTeC ECU with launch control and traction control are going to be for. But not before we get into the top end and do a port and polish of the head and throw in some Yosh STR-R cams. Need to have 200+ HP to get started in the amateur class.
 
#33 ·
This guy :lmao
Who are you trying to impress OP??
If you did your research before you did the tune and got some advice you would know that those numbers are off. I would not go back to that tuner.
Why would you even tune or do a track day if you know your ride is not running OK?
looking at what you are saying I think you are just telling stories and trolling.
 
#35 ·
There is no way your stock bike can make this kind of true hp. Haven't you heard of dyno's that read high. Well now you just experienced it 1st hand.

Another clue that should raise a red flag and make you question this dyno is you said your bike made more hp than a BMW s1000rr? Go to a diferent dyno.....

Just except the fact that this dyno is wrong.

So i put in new plugs. Still sputtery. Changed to the spare '11 ecu. Still sputtery.

So Eric says it has to be the power commander. We pull the fuel tank and look at the install my old mechanic did and discovered he had the piggyback harness on backwards. PCV was plugged into the secondary injectors and the SFM was on the primary injectors. We swapped them and now it's smooth as silk. I'm never taking my bike back to the original mechanic. That guy was a poser.

Also, on the dyno Eric used the SAE 5 correction factor. Dynojet dyno. Maybe it does read high but botton line I picked up 20hp on pump gas and 30 in vp mr-12 race fuel.

Also, no FI lights on the test run i took. Not saying its gone but so far so good. So ready to spend 3 days at jennings this weekend with a properly tuned bike!

LOL what a dud mechanic. I love when people call them selves mechanics and cant get the basics correct. :wtf

Sorry mate but those figures to me still look like a bit of overkill. I still dont think the gsxr can get 190hp at the wheel on a stock engine. I want mine to get there but to be honest i think mid 180hp at the rear wheel is more reasonable. I will get mine tuned soon when i find someone wurthy and will post the results
 
#43 ·
So how did Jennings go? Lap times?
 
#49 ·
It was fun. Bike ran great. No FI codes.

The rider....not so much. 1:28 was the best I could do with 1:30 being my consistent time. I know I can get more corner speed in 13 and 14 but any time I try to push harder I end up running wide.

I had a control rider do a lead/follow and he said my line is good and bp is good.
I guess maybe I'm slowing down to much from turn to turn in 7-11?

Regarding the "detune" comments what do you guys make of this video?


When you guys are saying it cant be "detuned to a 600" do you mean engine characteristics? Like the way it makes it power throughout the rev range and limiter? I've always just associated it with power output.

I have a couple dyno runs to do on saturday, if you want I can show you how easy it is to fudge numbers. I will post a pic of a dyno run I manipulated and what it actually pulled. I can make a gsxr 600 put out 300+ hp if I choose. Usually they fudge the numbers the other way though. They fudge the numbers low when they 1st dyno the bike, and then make the numbers correct to make it look like you gained alot.

Please do so that this guy can see that we aren't bullshitting him, and that his bike didn't gain 30rwhp from a tune and fuel.
