Reviews on DesmoPorsche/Houston SUperbikes ECU Reflash?

I plan to have my ecu sent in for a full system re-flash as well.  I already cut open the airbox and installed a BMC air filter.  I plan on a full Sparks exhaust in the future but I will run the udder until then.   Also, for resetting the TPS and idle trim, I will get the VDST tool.  

Questions on resetting the TPS: Is this to get the full range by resetting the 0 degree or the 90 degree position?   If not reset, is the 0 position off or is the 90 position off?

Questions on setting the idle trim: What is idle trim adjustment for? Is this idle fuel-air ratio or is it just idle speed?  If it is idle fuel-air ratio, then it is probably just adjusting it with no feedback of the actual result (no exhaust gas analyzer connected).

Question on syncing the throttle bodies:   What do I adjust to sync the throttle bodies?   Usually on twin carbed motors, it's the individual throttle cable after the Y connection or on the carb itself.  I will get a set of vacuum tester to monitor the vacuum.

Questions on setting the idle air screws:  For this, do I adjust the air screws while monitoring the VDST tool or is this adjusted until plugs are mousy brown?   If these are air screws, then IN means rich (and slower idle speed) and OUT means lean (and faster idle speed)?

Billruiz, I take it that you have the VDST?  How do you like it?

The VDSTS is handy for resetting the TPS and if you have an open loop ECU, tweak fuel trim etc...communication problems between computer and ECU can happen if you get loose connections with your USB cables.

Update....was having a few issues with the bike dying and also had some odd issues with the neutral light working onlly intermittently.

Called Bobby back and he said to send the ECU back and he'd reflash it and send me a new core, even though it wasn't clear all the issues were associated with the ECU.

The ECU is on the way back to me....pretty happy with the service so far.  I'll update after the reinstall.

How'd the reinstall go? 

All these "bike died a few times" and "dash warning lights flashing" have me a bit underwhelmed with the prospect of flashing my ECU.  Seems you can buy the DP unit for 460 from Houston Superbikes.  I wonder if you are guaranteed to avoid these re-flash problems by purchasing the stock race unit.

pretty sure those are flashed ones for sale.

I'll be installing my Termi/Spark exhaust this weekend and firing up the beast!  I also have the Houston SB ecu reflash and BMC filter/open top.  I'll report in after I get it dialed in.

Bingo.

My experience was great. If you expect to buy it, pop it in and have a perfect running bike you'll be disappointed. If you understand that you will have to set up fuel trim and reset your TPS, you'll be very happy.

I finally got a chance to open mine up in the past few weeks and I can say that it wakes the 695 up more than I thought it would. Low speed is smoothed out very substantially and the top end is definitely pulling harder. Even found the front wheel wanted to come up once or twice on my last spirited ride, something that it never did on stock tuning.

<-- Happy customer.

A TPS and fuel trim reset is what, an hour of labor at any dealership?

Max, and even that's a ripoff. Take the $100 they were going to charge you, double it to buy a VDSTS cable (or borrow one for a six pack) and never have to pay for small adjustments again.

It's a twenty minute process including test rides.

I plan to buy one.  They are located about 30 minutes away and I used to work for them.  Hoping for a discount!

By doing it myself, I'm missing the exhaust sniffer?  Big deal or no?  If I can set it to 95% of what the dealer could, I'm in.

I posted info on there on how to adjust your fuel trim by ear using a VDSTS. Only addition is that when you go out for a ride listen for the telltale lean signs. "Coughing" through the intake and popping on decel. Just to be used as ballpark, mine is set to 14. Yours will almost definitely be different, but there's a start.

You'll be damn close to what you would end up with a sniffer.
