Eka's Pretty TuneEcu Maps

eka · Jan 15, 2026

I have a bad habit to reprogram ECU all the time and try this and that. I just noticed, that i have reprogrammed ECU over 100 times and was like wtf. Better stop and maybe i share what i have done, so you don't have to be dork like me.

Anyways, original ignition map sucks. Values goes here and there too. I guess it is optimised for emission with restricted throttle valves. No way the maximum power comes under 30 degrees ignition advance in this big cylinders. Also low end was too lazy into my taste. Now the bike feels pretty much how i want it to be and got nice gain in useful areas. It is not dynoed, except with my accurate butt dyno. lol
If you look maps in graphic mode, you can see how crazy hasslings those are. I made them all pretty.

I have 31018 map myself, use European 95E lower octane and stock bike (except DNA-filter). I downloaded all TuneEcu maps for different regions and imported in those all my tune for F, I, ETV and AFR. It looks like all those had the same maps... at least those which i checked. I tried to attach maps here, but it's restricted to ten files. If you want to try my crazy unrestricted maps, here is download link:

Just select the map with the same number that TuneEcu shows from your bike.

If you want to try, notice that ignition advance is much earlier, different fuel and lower octane than 95E might cause detonation/knocking/pinging. I managed to have it few times before got it pretty good. If you hear like pinging noise, turn back home and adjust whole ignition map couple degrees lower, copy it to all gears and test again. Fuelling is probably a bit too rich and with dyno might find couple ponies more, but i have not easy access for that. It would be amazing, if somehow could get precise fuelling maps in my base maps.

And of course, you test maps at your own risk.

It is two spark plugs per cylinder and low revs.
These are some dyno runs with the 2.3 Rocket with different ignition advance. (Torque in Nm)
("Zündung Grad vor OT" is ignition degrees BTDC)
There is no need for big advance numbers. It just puts stress on the engine.
But I agree that at lower throttle openings you can get some gains. This area is controlled by emission laws and it is about NOX.

Yes, in higher load advance should be less. I iterated different angles and caps and this map was the best i found. At lower revs it should drop more or it starts pinging when open throttle. But if you look original map, it looks crazy hassling and that 22 degree advance doesn't make sense either as it is not supposed to open throttle bodies 100% originally. In my map advance rise relatively less when revs goes higher.

Original ignition hassling:

My pretty ignition map:

Those high values in original map is for engine breaking. Now it burble a bit, but i think it's just cool and i prefer that.

I did drive today like six hours at mountains with big grin. It is just so much better at areas you use at twisties. Traction control has to work way more too. When you cruise and hit throttle, it just shoots away instantly. With original ignition map you sometimes notice it has more power when you ease throttle a bit and it's annoying,

If you get Rocket on dyno, test this map and would be super cool, if you could trim it and fuelling with proper tools.

And of course there is more fuel where is more advance.

Tuned fuelling for original ignition map:

My iterated pretty fuelling map:

eka · Jan 17, 2026

I forgot to say that center cylinder runs hottest, rear one a bit colder and front one coldest. I made spreadsheet and tested a bit. I have termal camera in my phone. Of course it's not super accurate way to do it and there is two layers of metal in headers, but looks like the best result is comparing to F3 somewhere F2 +0,9 % more fuel and F1 -0,9% less in every cells. The bike runs butter smooth when cruising, but of course triple starts rocking everywhere when put more load and nothing to do for that. I have that fuelling difference in my maps.

Thanks for sharing this although, unfortunately, it's all way over my head. I'm sure that you've viewed and, no doubt, tried @Penner 's maps (who commented above). For the ECU uneducated among us, including me, how does your tune differ and WHY? Thanks

Interesting experiment! (on your bike, lol)

I have years of experience with well instrumented production tunning and have also tunned a dozen or so bikes on the street. I've had decent luck on the street tunning fuel with wide range O2 sensors (although never as good as a thorough dyno tune), but I've never had the balls to mess with factory timing on the street.

I think you're correct that there are drivability gains to be made if you don't care about emissions (especially with an aftermarket exhaust), I just don't know a good way to tell that you've crossed the line into preignition, especially since the Rocket doesn't have a legitimate knock sensor.

Preignition/detonation at high load can be immediately destructive, but over time, part throttle detonation can be just as bad.

great, can you please tell me , as my headers are increased to 2 inches and exhaust is running straight pipe, what changes do I need to make in map to get maximum power

Preignition/detonation at high load can be immediately destructive, but over time, part throttle detonation can be just as bad.

I have crossed it to detonate few times in certain areas when trying to find the limits, but right away backed up few degrees. At least my bike doesn't detonate now in these values. I made spreadsheet about difference between my experiment and the original map:

As you can see there is not so crazy difference. About that green area is where is feels so much better now. If you look for example 2500 rpm row and you see it actually drops below original values, if you hit suddenly full throttle. Differences jump here and there as original map is such a hassling...probably because as NOX emission which Penner mentioned. It doesn't detonate in my bike, but the bike feels so much stronger in that area and more fun at twisties. It is nicer to drive when something happens in lower revs too. Full throttle and higher revs it's not easy to do anything as speeds go up and always too much traffic or in smaller roads here is too much twisties. I just continued the map in the same direction as i noticed good. I made the table with spreadsheet with equal caps trying all kind of things. Well, at lower revs it drops more towards higher throttle to avoid detonating and for the same reason caps between rows at lower revs are bigger. At higher revs explosion has less time to make maximum pressure and i don't believe it happens before TDC and detonate. But as Penner showed there is not much difference in older Rocket if advance is between 20 - 30 degrees, which i assume was at full throttle. Anyway impossible to tune with butt dyno at public roads.

I have not had this bike at dyno to adjust perfect fuelling, but i assume my maps are pretty much on rich side. Penner tune is also richer than original map for optimum power, so i bet it won't get too lean. At least safer than original map for your bike. As my experimental maps have more ignition advance, maybe you should try couple procent more fuel just in case to avoid detonation, if you want to try. You can export F1, F2 and F3 tables in TuneECU. Then connect TuneECU tablet to computer (or phone), find the F1-3 maps and click one. In Windows it opens Notepad program, mark the table and copy. Then go to spreadsheet and paste. I use Open Office, but anyway when it ask, use tab as separator. Then copy also second time and in that second table put and copy in every cell =(first table cell in the same location)*1,02 for 2%. Then mark over and copy that second table and paste to Notepad program and save for example as F1_richer.txt somewhere in computer files. Make the same for F2 and F3 too. Then open resource manager and copy those table from computer to tablet through USB in the same folder where the map is. Then open TuneECU, go to F1, Select Table/Import and import F1_Richer etc. Penner tune has the same map in all F1-3, so it is one table job to import the same table to all F1-3. I can't say exactly how much richer you should make Penner tune to get max out and different pipes doesn't probably make the same difference in every area, so better get it dynoed, if possible. I would put in dyno mine, but around here i have found only dyno centers for cars.
