SERT for '08 Street Glide

[wagsbags]

Mike,

I'm confused and could use some insight into the workings of the SERT.

I've got a new '08 Street Glide due in next week and I ordered a SERT, SE A/C, and V&H slip-ons for it. I stopped by the dealer to see if the parts were in, and they confirmed that they had a SERT (P/N 32107-01G), SE A/C (P/N 297730-2C), and V&H Classic Slip-ons (P/N 16719) sitting in the back waiting for the bike to arrive.

However, I've read in some other forums that the SERT for the '08's is not out yet. So, I called H-D customer service and asked if the SERT was available for the '08's, and was told that, "NO, the 2008 models required a 32107-01H version and that it would not be available until Fall 2007". Furthermore, H-D cust. service recommending holding off on install of the A/C and pipes until the SERT comes in because it would further "lean out" an already lean engine.

My question is, will the current version of the SERT (i.e. 32107-01G) work on a 2008 (assuming that my dealer will have to do some custom mapping) or, are there changes to the ECM that will require different hardware/software interface? If it can be used, is there a canned map that you can sell me that will be close enough to use during break-in, since my dealer has recommended holding off on dyno tuning until the bike has at least 2,000 miles on it?

The older versions will not have the model code designations in the software to allow ECM recognition required for map downloading. Second, the touring models have larger throttle bodies and possibly (likely) different injectors, so the tuning constants may also be different (though we can change these). There may be other features/changes/updates we are yet to be aware of with the 08 models. If H-D follows historical past, earlier versions of SERT will work but only if your dealer/tuner has the latest software loaded into the computer used for tuning or downloads (so you'll still be waiting). This scenario also means the owner does not get the latest software CD (unless ordered seperately later) for their own use and so cannot do their own changes or mods.

With the O2 system, you should be able to install the 50 state legal mufflers so long as the stock air cleaner is left in place. Aftermarket or "race" mufflers (V&H) will still require recalibration via SERT. We will not have maps available due to the larger throttle body, these maps have yet to be developed as we're in the same boat.

Thanks Mike. Sounds like I better wait for the new '08 version of the SERT before doing anything with pipes or A/C. I'll just have to do the break-in with stock components.

Mike,

Is there any benefit to use the SERTvH over the SERTvG for a 2007 FLHX for better tunability/flexibility?

Mike

[Mike]

No, the updates are just software changes to allow recognition of VIN's and feature changes for new models.

Mike; Are you aware of any fuel management systems working with the 08 dressers? And seperately, my dealer says that flash they can do to the ecm to set the rear cyclinder to shut down when hot is terrible, loads up the engine and creates an oil smell. Any experience with that? When I bought the bike, they said a fuel management system would richen up the mixture and help it run cooler, but it looks months out according the manufacturers I talked to.

Thanks. Great forum,
Chris

[Mike]

I'm not aware of any aftermarket systems yet available for the 08 dressers. New ECM and harness will prevent earlier Power Commanders from working. Race Tuners are supposed to be released by end of this month. Digital Tech recals are available for "legal" combo's. We've only done a couple of the "EITMS" setups and so have not seen many issues. Once released, Race Tuners will allow many of these issues to be addressed and EITMS to be switched on/off as needed.

Thanks for getting back to me.

What do you know about a company called Dobeck Performance in regards to fuel management?

[Mike]

The TFI/DFO unit works OK for near stock setups like mufflers and air cleaner only. Still nowhere near the tunability of SERT and, as a piggy back signal modifier system, cannot address many of the background tables (the O2's are still going to try to correct the TFI settings, so now we have possible conflicts) and one more possible failure point. H-D has a similar unit in the "Race Fueler". Still not sure how even the H-D product deals with the closed loop conflicts. We just keep comming back to SERT.

I ordered their unit, I'll let you know how it works. Thanks again for the input.

Hi Mike,

Well, as you undoubtedly know, the new '08 SERT's are finally out and I had the dealer install one, along with a SE A/C and V/H Classic Round slip-ons, on my '08 Street Glide. However, they (the dealer) did not dyno tune the bike because they said it would change too much during break-in period and the tune would no longer be optimized once the engine was broken in. They recommended bringing it back when I get 2500 miles on the bike (it currently has about 800) and they will tune it then. I'm not sure what map they used, but I'm sure that if it's a canned HD map, it's not even close.

My questions are:
(1) Do you have a map available for the above combo?
(2) If the answer to the 1st question is NO due to the changes in TB etc in the '08's vs '07's, would the map you have at least be a closer fit than any of the canned HD maps?
(3) Finally, if answer to (1) and (2) are NO, what HD map would you recommend during break-in, and what are the downsides to using this map for the next 1700 miles (i.e. any possibility of overheating or damge to engine)?

Thanks for your help.

Thought I'd let ya'll now that I installed the TFI unit a few weeks back. I did it myself while installing Bassani true duals on my '08 Road King CVO. I have a SERT on my 100hp 95ci Deuce and it works great BUT, in this application, only changing pipes and air cleaner, this thing works great. Even my dealer was surprised! If you have a dyno in your garage, the SERT is the way to go. But if your a seat-of-the-pants tuner/tinkerer, this things great. You can adjust it yourself, and if you don't like what you did, just go back to the default setting. Not bad for half the SERT's price.

I may cave to peer pressure and install a SERT in the future or with cams in the winter but for now, with the pipes and the tuner, I get the front end right off the ground with just throttle, the plugs look great and it scares the crap out of the wife! That's enough bang for a bagger for now!

Peace

[Mike]

Scaring the wife! Priceless!! Thanks for the update.
Mike

[Mike]

Not many yet for the FBW bikes. Other models can use converted files. The only real canned choice is #100, 200TL001. You may try experimenting with maps for larger displacement, mild combo's. In the meantime, the bike should not be any leaner or hotter than stock so it should be fine. I you are worried, reinstall the stock air cleaner until you've got the milage your dealer needs to dyno.

Mike,

Actually, the bike is running pretty well - no pinging, minimal popping on decel, and, seat of the pants anyway, seems to have more power. It also appears to be running cooler, which is the main reason I decided to go with the SERT. So, whatever map the dealer loaded appears to be doing the trick. I think I'll just leave well enough alone, for now.

Thanks for your insight, though. You continue to provide an invaluable service to the HD community.

How much to SERT's cost? I have a 2007 Street Glide with 9500 miles and ever since I hit 7500 have a lot of decel popping. The bike had cycle shack mufflers put on before it left the showroom floor and everything performed great until recently. Plugs have been changed twice and the mufflers have been removed and put ultra copper on the pipes and reinstalled the mufflers to no avail. Using SERT's seems to be awful expensive especially if you have to keep taking the bike to the dealer to be charged everytime they touch it. Wouldn't V/H fuel pak be more feasible especially since they have already tested their product?

[Mike]

The SERT cost is $459.95 and 08 version 4.7.6 is in stock and available through our Internet Sales dept. SERT comes with a tuning manual and allows owner edits to the cal files via a laptop or other. Full custom mapping does require a dyno facility and would be rrecommended whenever something is changed that changes air flow through the motor. Fuel Pak may be an option for mild or near stock motors but check there web site cal files to make sure there is a match to your combo before purchasing. Fuel Pak may, however, set up certain conflicts with the closed loop system and we are not real sure how this will affect the system over time. Depending on the issues your are trying to solve, the Fuel Pak may not address them (decel pop being one).

wagsbags.... have same V&H Slipons on my 08... which map are you using? 100?

Cheers,

Ken

[wagsbags]

Yep, I'm running the 100 map. I have to say, my bike seems to be running well on it, though. How about yours?

[KenInVic]

havent loaded the SERT map yet cause I am waiting for my SE Air Filter.... thanks for being the guinea pig though, will try map 100.
