I had my first ride today and it felt much beter than the Fuelpak
Excellent performance …
No misfire anymore, but still decel popping.
Do you think this must be an exhaust leak then?
But than this must be where the exhaust is fixed to the engine because I have the V&H big shots..

As you may probably know, it´s not the best time in Germany to go out for a test ride
Hopefully next weekend, but even after starting the engine and let it run a few minutes it sounds better than before with the V&H Fuekpak.
I´ll send another post after I did my first run, ok?

Tom How do you like the SLM? The SLM will always flash. After open loop you’ll only flasn green.

Sorry.. forget my last post..
I have read the installation sheet again and everything is fine now.
I thought the controll lamp on the SLM should stop blink, but it´s the factory FI–Light and this is working fine..
And after another 90 sec. the LED on the SLM is changing to blink green only when it comes to local loop mode

Hi,

I´ve just put in the SLM-04 tp my 2007 SteretBob, but the self diagnostoc lamp is permanently flashing read and green and I thought it should be off after a few flashes?!?
Any idea what the reason could be?

Thanks..

Gary 10 pounds of boost is a lot for a stock motor. What elevation do you live at? A 96″ Twin Cam engine has slightly over 9-1 compression. I would think 10 pounds of boost at sea level would put your static compression ratio too high for pump gas. You may want to talk to the Pro Charger people about that. There are a few good camshafts that would work well with the SuperCharger and could help with detonation. I would suggest replacing the stock cam.

Everything is stock except for the pipes. I plan on doing some V&H Monster Ovals slip ons. I want to do a cam but for now im going to leave it all stock. The supercharger is for 10 lbs of boost. Will the SLM work with this setup? Thanks Again

Jim, Are you planing any other modifications to your engine? I have used the SLM with Nitrous and had excellent results. Are you planing to do a cam change for the supercharger? What heads do you have are they stock ? How many cubic inch 96,103 or 110. A camshaft specifically designed for a supercharger would make a huge difference. I can help you out with a good cam choice. That is my field of expertise. racengineering@gmail.com

Hi Jim, I know a little about these units. I have been using them for a few years now. Information from the SLM sent back to the ECU is evaluated and possessed the ecu will make the timing changes according to the information it recieved. Yes essentially it doe’s.

By: Jim

Jim — Mon, 12 Oct 2009 11:37:13 +0000

Joe, does the SLM adjust timing, or just the AFR?

Hogmaster, thank you for your ongoing interest and offer to assist with the problem I am having. Basically, I am getting a “flat spot” between 0% throttle and 1,500 rpm. I am going to take my bike back to the HD dearlership that installed my cams to run some checks (as you have suggested). Thanks again. I will keep you posted.

Phil, I have installed many sets of Cams with the SLM modules I havent had any issues with throttle response. What did the installer think of the performance. something as simple as a set of spark plugs could be an issue. 4164 autolite’s have been my plug of choice. What about the popping is it gone? There are a lot of things that could throw off a tune up. I would check the compression and drain the crankcase to see if there is an abnormal of oil in it you should only get a few ounces. More than that could be another problem. A compression test is the best way to determine if their is a real problem. Go to Andrewsproducts.com they have a trouble shooting section that will show you how compression effects your engines performance. I wouldnt be to quick to blame the SLM swapping it may not solve your problem. I would like to help you with this problem. I have complete confidence in this product and a few years experience installing them on a variety of combination’s Keep me informed Racengineering@gmail.com.

Hogmaster, the cams are great but I am still having issues with the SLM when accelerating from 0% throttle. Accel is trying to resolve the issue.

Phil, Did you get some miles on your bike?do you like it.

By: Hogmaster

Hogmaster — Sat, 03 Oct 2009 03:20:54 +0000

Phil, Im sure your pleased with the performance of your Bike with cam installed. That is what these Twin Cam engines need to reach their potential. We really haven’t had customers complain about throttle response. Give it a few miles and see if it improves. Throttle by wire bikes are typically s bit slower to respond because of the nature of the unit. If you do dyno your bike let me know what kind of numbers you get with the 204’s. I wish we could have got you a set of the SLM 96″ cams. Have fun and watch out for Cops.

Phil L — Fri, 02 Oct 2009 21:47:34 +0000

Hogmaster, thank you for your comments (as always). The 204 cams were installed today and I cannot believe the improvement in acceleration. And, the sound is awesome. Question: how long does the SLM take to readjust to the change with the cams? I have only driven the bike home from the dealership (15 miles). It accelerates great and the bang and popping I was getting before the cam installation on decel is GONE. I suppose it could have been a leak in the exhaust (as you suggested) that was corrected when they reinstalled the headers. The only negative that I have noticed (at this early stage) is some hesitation in throttle response from a dead stop. I am wondering if the SLM is still trying to adjust to the new system. Any thoughts? Have any of your customers experienced the “hesitation” immediately after installing cams?

Phil, what I forgot to mention the SLM cams are all American steel and made right here. Product of the USA.

By: Hogmaster

Hogmaster — Fri, 02 Oct 2009 16:38:52 +0000

Phil, The 204 cams are .508 lift nice bolt in cam. If you read some of The earlier posts here I have been installing camshafts with the SLM module for a couple of years now .Accel has 6 of 10 different profile camshafts specifically designed to work with fuel injected twin cam engines. We have had 30 percent plus gains and still retain good fuel mileage. They have a specific grind for the 96″ engine.
.535 lift with a 33 degree intake closing great for improved torque. The 204 cams close at 34 degrees and have more duration this will give you a later power band with torque in a higher RPM range. A heavy bike needs its torque down low to provide more pulling power. To perform this job with the adjustable pushrods your looking at approximately 4-5 hours depending on the exhaust. No dyno time required. We do cam installations more than anything else in the shop. Cams are going to give you the biggest performance gain combined with the SLM and a good set of pipes you’ll think you you gained a couple cylinders. SLM cams are 4340 billet steel ground on a CNC Landis machine that costs over a million dollars. This is the most accurate piece of cam grinding equipment in the world and the operator has over 30 years experience. Best piece money can buy. I highly recommend them.

Hogmaster, I am getting ready to have the SE204 camshaft installed on my 2009 Ultra Classic, which will be a good test for the Accel SLM. Since no mapping will be required and I have a set of the quick install, adjustable pushrods, how much time is normally required for an experienced mechanic to complete the camshaft installation?

Ralph installed an SLM on my 2001 Softail before I went on my annual trip to Sturgis. I have 211 cams,Screamin Eagle heads and Rhinehart exhaust. What a difference. The engine not only performs flawlessly but it even seems smoother. My fuel mileage improved and . my oil stayed clean longer. The engine even sounds better My brother had Ralph do his 103 as soon as we got back .
A few of my other friends have also had the SLM’s installed since. I had Many trips to Harley and the dyno with my race tuner they never got it dialed in like this. Im their new best salesman.

Phil, One other thing.Tr y closing the throttle quickly on deceleration.
Injected engines respond differently than carburetor engine rolling the throttle back can cause a slight popping. You can do this before checking the exhaust.

Hogmaster — Fri, 25 Sep 2009 15:20:31 +0000

Phil, It is possible you may have an exhaust leak. I would check the muffler clamps to make sure they are tight. remove the brackets behind your saddle bags and see if the mufflers move on the head pipe. I have found this to be a problem and I use sealer on the connection permatex hi temp exhaust sealer works very well.

Hogmaster – thank you for your comments. I had roughly 7K miles on my Ultra when I had the upgrades installed, including the SLM and, yes, I have disconnected the power from the battery twice since I had it installed (to connect battery tender leads and a security system). Based on your comments and others, I am not going to worry about the discoloration. Any thoughts on what I can do to eliminate the decel popping?

I would like to commet on the SLM. I had it installed about two months ago. It works just as good as I was told it would on my 2009 FLHTCU. I have put over 4,000 miles on it so far. It has great response to the throttle with out any delay. It also gives me greater gas mileage compared to other FLHTCU’S that I went on trps with they were the same year as mine. It also seems like the bike runs a little cooler. If anyone is thinking of getting one I highly recommed doing so. I ride with a group called the P.O.E.T.S. and alot of them are going to get the SLM put on there bikes too.
