Is there any difference between how Motowheels and Redline reflashes your ECU? I was prepared to send my ECU to Redline until I found out how much it costs to overnight it from San Francisco (my hyper is my primary mode of transportation). Motowheels is $50 cheaper for the actual reflash, and would cost less for shipping too, since it's in California.

Thoughts? Although shipping prices would kill me, I'm willing to send my ECU to Redline if their process is significantly better.

I don't have a comparison to go by... But after screwing around with a Bazzaz for months with no joy I got a reflash from redline and the results were transformative. The bike is smooth even at 3000 rpm and revs smoothly to wherever the hell you want... I haven't managed to set off the rev limiter yet. This is finally everything the hyper should have been out the box. Definitely the best money you can spend on your bike.

Pick your options carefully. They give you a lot of latitude and you get exactly what you order... So make sure you order right!

Before dissing the Bazzaz too much I will say that while their "solution" to the closed loop lean issue at low revs sucks ass, it IS really nice in combination with a reflashed, open loop ECU to get fueling exactly right in combo with the O2 sensor. That said, the Bazzaz with sensor is twice the price of a reflash, and is a fine tune to the already excellent job done by the redline reflash.

There's a lot of praise to be found on here for the Redline reflash, so I'll just assume I was the odd man out. The reflash I got didn't really do a whole lot for me. There was no religious experience when I took the flashed bike out for a spin and it popped on decel and bucked just about as much after the reflash as before. I had planned to get a PCV together with the reflash though and was mostly after getting rid of the closed loop in order to tune the whole RPM band with the PCV. Once the bike was dyno'd and tuned with the PCV there was a significant difference. For me the reflash by itself was pretty useless. YMMV.

Oh, and I have the same mods as you, 14T front and an LV cat delete.

I did my reflash with the LV cat delete I bought from MotoWheels. LOVED the results, I would say go with MW since they're closer to you.

Sweet, I'm considering it. I'm so indecisive! If I end up sending it to redline, I'll probably end up doing 2 or 3 day shipping to keep the cost down, and just suck it up and take the bus to and from work.

Did the Motowheels reflash remove a lot of the low end surging?

The maps are the same.

Just sent my ECU off to you guys - should be there tomorrow morning around 10:30!

Moto. In what sense are they the same—as in exactly? I thought it's customized depending on the installed modification—ie. the one with modified air box will NOT get the same map as the one that's completely stock. I've got the DP ECU that came with my 2-2 Termis.... will your map be richer than this + removal of the closed loop?

I was asking myself the same question but the site sponsor never answered yours.
I'm contacting Redline today to ask questions about my proposed recipe and reflash for my 2010 Hyper 1100 EVO:

Airbox Mod (one hole or two)
BMC Filter
LV Cat Delete
Open Loop
Optimize AF Ratio
Exhaust Flapper Valve (purpose, what to do with it, remove, disconnect, nothing?)
Keeping Stock Exhaust

Short of dyno tuning I hope this will enhance/transform the bike to improve drivability.

What he means by the same is that you probably get the same mapping from the 2 shops for a given configuration. The shops have a portfolio of maps (probably from the same source in Italy) from which they select the recommended one that suits your particular bike setup (which you specify when you send your ECU).
Unless the shop generates their own maps using their in-house dyno.

That's my guess, I could be wrong.

Motowheels here on my 2010. Its a phenomenal change with corse stacks kn filters, 14t sprocket, and full zard ti. It is soooo much easier to ride with a useable rpm range from 3k-8.5k always.

They will both use the Rexxer flasher, because as far as I know, it's the only solution that exists for the Siemens ECU 's.

As for the maps, there's a bunch of "canned" ones that they are likely to use, unless one or the other have tweaked them slightly. However, since they are both "guestimating" without actually having your bike on hand, I doubt there would be much individual tweaking for each client.

I know it's too late for you, but did you think about ordering the flash unit itself? Yes it's more expensive, but you don't have to disassemble anything on the bike, don't miss out on riding, don't pay for express shipping, can read and clear any subsequent error codes, and most importantly, clear the little service wrench when due!

FYI, I went with the Redline map and am very happy. Nothing to compare to except stock but the result was striking.

Buying the Rexxer flasher? Is that even a cost-effective approach?

Spoke with Redline yesterday. Answered all my questions. We talked about buying the Rexxer unit for $600. Probably a worthwhile investment for someone who is going to switch between maps (race, street, etc). For my application it's not worth it. Just want to make the bike better than stock. Down time not an issue. Have a SM610 and my wife's little KLX250SF if I need a fix.
Thanks for the replies.

It all depends on the relative worth you place on the advantages I outlined above.

Before reading thru ALL the posts I sent you a PM P90Wex. Guess you can disregard my advice and connection at this point my man. Hope it works out well as the guys at MW are true pro's too.

We use the same Rexxer device and we pick from the same collection of maps. In that way they are exactly the same.

We can re-flash your DP ECU, but I don't know if it will make that big of a difference since in theory the ECU was designed for that exhaust and you should have the closed loop removed as well.

I'd contact [email protected] to see what he has for your bike. He is the one that deals with all the Rexxer tunes.

Hi Martin,

I prepaid for an ECU remap when I bought my LV cat eliminator from you guys. I haven't installed it yet but can you shed some light on the following questions?

1 - Is it true that for the fee I paid, MW will reflash my ECU more than once if I make further modifications to my exhaust?

2 - I bought a used ECU off an identical bike thinking it might be more convenient and safer to reflash that ECU while leaving my stock ECU intact. However, it was recently brought to my attention that it's not that easy because of the built-in immobilizer feature that ties each ECU to its native bike.

Thanks

Hmmmm. A very interesting thread to say the least.

The reflash allows you to add mods like a slip on, cat delete and air filter which is great but plan on your bike being slower before you add those mods. The reflash I had just enriched the hell out of my bike and made it slow. I've got my bike being tuned on the dyno now with the rexxer software.

Looking forward to riding it soon!
