Reviews on DesmoPorsche/Houston SUperbikes ECU Reflash?

[booger]

Exactly, Case.
You can go way too far with this stuff. Reflashing with an immobilizer disable and a freeflow intake+exhaust should satisfy the 99%ers. After that it's big money for diminishing returns, especially on a 2V wet clutch bike. As an S2R800 owner, I have the DP ECU and airbox, and freeflow exhaust. It has helped with the low RPM range a great deal, roll-ons are smoother and slightly stronger, and the redline was increased a bit. I can now poke around smoothly in traffic at RPMs as low as 2k with no snatching but peak brute force power hasn't been changed much. Just smoother all around, with the feeling that's it's running as it should. You're not going to extract massive power gains without expensive engine work and the fueling mods to match. At that point it's easier to just get a more powerful motorcycle, which will likely come with better suspension and brakes to go with the extra power.

07 S2R open air box, full Arrows.  Got the reflash from Desmo Porsche, had the dealer adjust TPS and still getting engine hunting (pulsating) at idle.   Anyone else having this issue?  Other than that bike is much smoother and civilized to ride at low RPM's, around town and slow 2nd gear turns.

S2R isn't enough of a descriptor for any help. S2R 800 or 1000?

Sorry, 1000

Joe it's a twin, it will never be smooth as glass at idle. Check for vac leaks. Synch the throttle bodies and bump the fueling up a couple of points till the plugs are light brown.

heres a tutorial/review I did on his ECU reflash

Bookmarking as i may get my ECU done this year.

I just got mine reflashed by them and got it installed a few weeks ago.  I have a 07 S4Rs with a full exhaust and I opened the airbox at the same time I had the remapped ECU installed.  I went with the full race map, disabled the O2 sensor but left the immobilizer alone.  I dealt with Bobby there and his service was really good.

Before the remap (when I was running the full exhaust on the stock ECU), but bike ran pretty well.  Idled well, etc.   The only issue was a slight burbling on decel.

After the remap the burbling seemed to disappear.  The bike runs well and seems maybe a bit faster, but it's hard to tell for sure.

My concern is that the bike has stalled a few times in the five or six rides I've taken it on, where it had only done that once in the year prior.  It hasn't happened on the last few rides though, so hopefully it was just a glitch or something.  We'll see.

maybe you suck at the clutch

Stalled when idling, fool!

that's "it died" rather than it stalled.

Don't think it was a glitch.  I had exactly the same issue after my remap.  07 S2R1000.  Had to have the TPS and air set by the dealer.  They didn't get it right the first time had to go back a second time. Bike runs great now.  Did you notice a huge difference when starting from 1st gear or cornering in first gear like at a stop sign?  The throttle response should be smooth instead of jerky.

So I should probably post my own results since I made the thread and all.

Sent it out, had it back in six days, even over the Christmas holiday. Popped it in and fired right up. Reset the TPS, adjusted fuel trim, and went out for a ride.

As expected not an incredible power increase according to the butt dyno, maybe a horse or two but anyone that tells you it's a huge gain is pulling your leg and their own. The MASSIVE improvement was in low speed low RPM. Making low speed turns around town no longer lugs, and accelerating away from a stoplight requires less clutch work.

Very pleased with service and product, A+ in my book.

Banged it off the rev limiter yet? That's where you should be experiencing the hp gain from the dyno runs I've seen done first hand and from the charts of others. Peak power. But it's all dependent on what you've done - if it's mapped for a full system and you've got stock pipes or just slip-ons, then It should be rich and not too much more powah.

Making no adjustments besides TPS, I removed the airbox cover and RTV'd the filter. I let it dry for a couple days and tested the RTV. Filter can be removed easily and RTV removed from filter and airbox as well. Installed new plugs and rode as usual for a week. Still running rich (reflashed ECU, S4RS, full Zards system), so adjusted fuel trim from +5 to -5 just to see what happens. Lo and behold it runs a lot better, no decel pops, no residue on the tips of my exhaust. It seems to run a bit hotter according to the temp gauge, but nowhere near the 200's. I'm speculating perhaps the Zards full system may be a bit more restrictive than the Termis. Plugs look good (tan), so I don't feel the need to tweak the trim any further. Besides just getting the laptop hooked up is a pain let alone multiple plug checks.
