Power Commander Tune Maps.

Never been a fan of those canister junks, and their rather useless functionality... typical emissions BS

Is that so? Not so much coincidence as it's pretty much the only path to some power on this bike I guess...

Do you mean deleting the catalytic?

Negative, I lost that when I fitted my Yoshi full-system.

I'm referring to the air injection valve delete

http://cb1100forum.com/forum/showthread.php?tid=1824 Ah thank you! I actually like my decel popping tho haha. I wasn't sure if there was a new modification I hadn't read about yet but I did read that Pair valve delete a while back I believe.

For the pair- I simply pulled the main hose and stuff a rubber vacuum cap of the right size inside it and put the hose back on the valve cover. Looks stock, and only takes a couple minutes to do, or remove if desired.

As much as I have changed on the bike- I want it to look like it rolled out of the factory this way- in 1982.

No need to go crazy with deleting anything unless you are wanting a 'cleaner' look or 'lighter weight'...which would be negligible. Also no need for the 'block off plates' you see people use.

I'll see if I can find my old pics...
And since you mentioned the velocity stacks-

Yea those pics are gonna help alot when I figure out how to open the airbox.

Do you think its foolish to do the velocity stacks mod with the stock headers or should I continue to wait for the exhaust first?


I already have
1. ECU flash with speed limiter removal, ignition timing retardation is fixed, RPMs raised,
2. PCV with yoshi slip on map (I have a shorty GP tip)

I just dont want to cause a lean condition before I can get either it autotuned or it on a dyno. But I guess the catalytic would be the bottle neck on the way out?

I wouldn't be afraid of doing the stacks now as you already have some fuel. Maybe too much even.

Interesting that you are running both the tune AND the PC5 without autotune because you are probably telling the bike to add fuel twice without each part ordering more fueling knowing that the other part exists. You have no feedback capability- just 2 people telling the injectors what to do- without giving them a chance to speak to the boss.

How is your mileage? Sooty exhaust tip?

Mileage is good, no noticeable difference from stock really. I remember Ghuls telling my mechanic they could have done more with my ECU after I got the exhaust but they kept it fairly conservative since I still had a stock bike at the time.

I should give them a call and ask about that.

No symptoms of sooty exhaust or plugs. I had the RPMs stuttering at highway speeds with the flash alone so the PVC fixed that. Bandaids on bandaids haha

I was planning on doing the stacks, full yoshi exhaust, and have my shop do a custom tune on the PCV all at the same time. But I also had an accident and it messed with my plans haha

It probably is just ME but sometimes I wonder if trying to get more out of the engine and engine management is more hassle than it is worth. I am very happy with the way the bike runs but I fully understand that some riders want more , it is probably just my age !

I am also happy with the way it runs, but I do want more sound! It sounds like a hair dryer. I drilled the end plate almost completely out, but it made very little difference. I was thinking of decatting it, but my BIL says that will introduce tuning problems, so I don't know. I modded the exhaust of my first Nighthawk 750 and it sounded great. My second Nighthawk had a Yoshimura pipe that I repacked to tone it down some and raised the needle on the carbs.

I have this exact shortt exhaust, it actually has a small glass pack in the side walls you can replace occasionally. Its significantly louder than the stock exhaust and its 1 stainless steel band to install.

Very clean looking exhaust end, weighs almost nothing, all the room in the world for aftermarket mounting saddle bags without a muffler in the way. And it sounds awesome - not obnoxious but not quiet. Its quiet on the low end and around town but when you wanna open her up you'll hear her roar lol.

I'll add it to the list of things to do. I just found out my 1981 kz440 ltd has tubes as I was mounting my new Kenda Cruiser tires on

... once I sort that out I will do a video this week and get my headlight bucket over to daymaker to start making our CBs their own custom headlight kits for significantly less than competitors.

I'm trying to contribute to our community the best I can! Lots of emails lol

I'd be interested in a better headlight if it doesn't look out of place.

Hi, I'm installing a full Delkevic with 9", O2 delete, stock air filter with funnel, PCV and would like a map for Denver CO, so 5280' altitude. Can anyone share a PCV map for these mods? Thanks, Frank

 

[PowerDubs_imp]

No- anything anyone would give you would be a guess at best.

None of them files have the tsr funnel, none of the files are at that altitude- to get the best results, add the auto tune box.

Actually, the TSR map does account for the TSR funnels. So sayeth TSR anyway.

 

[mvk24_imp]

Best bet with this thread intention was for someone thats had a custom tune for specific mods to share they're map file. As stated above the 3 stocks maps power commander have on their website are useless.

My intention was if someone had already had their bike dyno tuned with x exhaust and x modification at x Altitude than they could copy that map from their PCV and post the file on here.

Sent from my SM-G965U1 using Tapatalk
I've been hoping someone at sea level has also done the ECU flash(ignition timing, raise limiter, remove speed limiter), aftermarket muffler.

Have then had their bike tuned and is willing to share the map.

For the same reason I've held off honing the air intake funnels because I don't have a map for it.

TSR released a map?

[PowerDubs_imp]

They may have. The files from Dynojet aren’t with the TSR.

The altitude is still going to be more than enough of a change that I wouldn’t wouldn’t go with an off the shelf file.

In fact, at least for what I’ve seen on my own bike playing with the dyno- anything past a slip on muffler would be enough that I would want the auto tune box or pay a shop to dyno tune.

Of course, some people may be more inclined for ‘good enough’ and that’s up to them.
