Had my H2 SX SE Flashed and Tuned yesterday. 4

Recommended Posts

I took my bike to get de-restricted and tuned. We used woolich tuning software. 

Baseline we did 3 runs and got 161hp, 163hp and 164hp with 84ft.lbs. on the 3rd run. The third run sent the bike into limp mode. We learned that it was because we didn't hook the ECU up and disable the front wheel speed sensor fault code. . 

The tuning shop had ordered a bench flashing harness so the ECU had to be removed from the bike to connect it to the computer. The diagnostic reset only works with the ECU in the bike. So we had to, 1. idle the bike for 30 sec or more, 2. take the bike out and ride it around at over 25mph for 5-10 min 3 shut it off and repeat 3 times. Riding the bike over 25mph for 5 minutes at a time is a lot harder than it sounds in Tucson. . Did I mention it was 99° at noon today? 

Finally got the fault codes cleared and back on the dyno and we were able to start the tuning. Took the throttle valve restrictions out and ran it. It gained 5hp and the A/F reading was spiking lean at 10k rpms . So the tuner kept adding fuel until it started losing power but the lean spike at 10k was still there. Here is where it really exceeded my comprehension level. He said it was running so rich the dynos A/F reader was seeing it as lean . He pulled fuel and it started making power. 

He got it up to 184hp 93 ft.lbs safely. Then we started talking about bumping the redline 500rpms. I told him I was pretty sure woolich had done it. We decided we trusted woolich. So we decided to send it and try 13,000rpms. I attached the video of the bikes first time revving to 13,000rpms. The bike made 209 hp 96ft.lbs. without changing the timing or fueling. 

The tuner reached out to Anthony (WR NA) who reached out to woolich to see how aggressive they were running the timing on the H2 SX SE they tuned. After confirming that they had successfully been more aggressive with the timing we decided to get a little more aggressive. The bike made 216hp and 99ft.lbs. We then did 4 back to back runs. Runs 1 and 2 were 216hp then run 3 was 206 run 4 was 203. Since the bike was pulling power as it got hotter we decided to back the timing down a little to be safer. 

My tune is a little on the aggressive side but the tuner and I both feel it is safe. My final setup resulted in 213hp and 97ft.lbs. after backing it down. So we added 49hp and 13ft.lbs. from a filter swap and tune. 

The tuner even took the time to help me dial in my suspension which was awesome. 

It is a totally different monster. I didn't really get a chance to push it because it was dark when I left. Night time along the 45 mile ride home means more drunks, animals and cops. But I did play with it as little. My first impressions of the bike when I first got it I thought the bike didn't really have the violent acceleration you'd expect. It was still fast but very refined and smooth. Now at lower rpms and throttle input the bike feels just as refined and smooth but it feels like there is less resistance working against it. Kind of like pushing a box across the ground vs pushing a box around that's sitting on a skateboard. But at full throttle holy cow it has some vicious acceleration. It's violent like the bike is trying to accelerate so fast the rider flys of the back. I love it! 

I did get a couple graphs, a base line vs final tune and the 216hp graph vs my old 174hp zx10r (air filter,  2/3rds exhaust, de-restricted, tuned) for comparison.

I can't wait until reputable exhaust systems start coming out for it. One of the cool things about ECU tuning on this bike is that the 3 power modes can all be set up differently. I think after I get an exhaust for it I might have them set one of the power modes up as a race gas mode.

Good lawd. I know what 168hp feels like and I think thats already too much. 200's is mind boggling.

thumbs up.  I have woolich racing flash kit on my laptop.   I used their autotune and it made the bike feel very good.  wanted to get on a dyno but the local shop sold it.  damn.  i did have the autoblipper sensor fail.  got a new one under warranty.   a little worried about them now.  

also make sure the traction control is off on new bikes with it.  it will back off the power if it thinks the wheel is spinning.

:wtf: That's crazy how much more you can get out of it, just with a tune.

 They were pretty helpful we ran it to some confusing issues with the bike since its the first H2 SX SE the tuner has seen. So we were sending lots of messages back and forth to them. I didn't add any extra parts or anything from the "race tools" kit just used their software to de-restrict the bike and change the timing and fueling. The bike has a factory quick shifter and launch control so the only add on they really offer at this point is the pit lane limiter and the warm up mode.

your bike has an autoblipper too?  the r1 just started coming with them.  mine didn't have it. that was one of the many reasons I bought the kit.  plus unlike FTECU you can use the software without internet connection.  FTECU is a pain in the ass with that.

 

anthony from woolich is the man.  he was helping me at 9pm on a sat.  I didn't necessarily need his help at that time. I was glad to wait till monday.  but he still did it.

Yeah it has up and down quick shifting with auto blip, launch control, heated grips and cruise control among other things. 

 

Anthony was a lot of help. We were contacting him pretty much all day well into the evening.

Here is a video that you can hear the supercharger chirping when the tuner lets off of the gas.
