Timing advance in degree/RPM curve
Anyone have a graphic of the ignition timing advance of the SuperHawk/Firestorm???
This is an example of what i'm looking for... but is for Aprilia RS250... I search the same graphic, but for our bike...
Thanks!!!!

Well did you sort out your ignition problems ?? I guess you reverted to the aftermarket.
These are not the stocker, this a stock engine with non stock pipes and intake and a turbo of course, it may differ slightly and may not be zeroed, I was sick of recieving oil in my eyes from the timing sessions and I tuned it as is, but it's close to 0
It's tuned as minimum timing for best torque on 91 octane here, about 98 in Italy
Still it gives a good starting point for dyno tuning
Ignore the bins over 100 Kpa, this is turbo territory and don't forget my VE is lower so I may advance a bit more because of the turbine restriction and some reversion, so don't use it without verifying the plugs often for aluminium bits on the ceramic.
This engine is a timing *****, sure a big bore like advance, but the squish and combustion chamber design is not optimal, there is something to be gained there, will start a thread on this when I get more time.
The 0 to 3100 RPM load may be off due to the use of a false load algorithm Alpha-N, Throttle VS RPM, then revert to MAP VS RPM speed density algorithm witch reflect true load, but there is little difference in timing, the fuel table on the other side won't work unless you set the same Alpha-N table that emulate a load in Kpa from the TPS signal, because of the bad vacuum signal of a V-twin.

Hi gboezio!
No, I hav'nt solve my electrical problems, but I'm waiting a visit from a friend at my home (he's electrical engineer).
I'm looking for the original parameters of the ignition timing because I'm interested into a racing full programmable unit system... after I have solve my actual problem, of course!
But for change the parameters, first I need of the original settings... so, first to buy, I want to be sure that this parameters are available...
Ah, what type of programmable unit could you use in your bike?

There are units sold as board only for 200 $, but the aluminuim casing and Ampseal connector are too awesome to pass for 400 USD
To drive our bikes you need to install a Hall effect cam sensor, maybe the Varadero parts would work but I made one myself, you need the Varadero crank wheel since the one we have is unsuitable, I cut off one tooth as a signal pickup, still I recommend to use the stock computer since there is a lot to do to make this work properly and it's simpler, maybe a 4° ignition advancer.
If you intend to modify the engine, specially compression and run high octane gas later, then you should have full control over spark .
One thing for sure, Microsquirt is good to learn about EFI, it's not plug and play, some people have done it on the RC-51 (VTR1000 SP1 and SP2), using a 12 tooth wheel and the 3 tooth Varadero Cam wheel and sensor, there is a special code written specially for it at MS-Extra
To drive the converter trough the inputs, you need to set coil dwell to 2 mS and spark duration to 1 mS, this will ground the inputs for 2 miliseconds and release 1 mS, the stock converter is so powerful that it will ignite anything.

timing curve
So does anyone know the timing curve of a stocker? I can see the modded tune has 31 deg of lead up top at 180 kpa over 10 psi. The stock hawk must run in the high 30s(ideally) i much doubt it though i get away with standard ULP no sign of detonation at all.

the whole table may be shifted a few degree off, I had a hard time to zero it to TDC, these are the result of MBT
That would be nice to set the TPS to WOT and do some RPM plots on a stock bike.

You could also get this... http://www.ignitech.cz/english/aindex.htm the programmable one there is used by a member on the Swedish VTR forum with good results...

And finally... I've found the original parameters!
I've send my original unit at Jan Matous of Ignitech, and he extract the parameters whit his instruments and software...
That's the results of a long job...

I'm curious - is this simply reading the map out of the ignition timing computer directly? If this was obtained experimentally, can how exactly does one get the engine to 10,000 rpms with 0% throttle?
#15
When at rev limiter you close the throttle, you have 10.000rpm at 0%TPS....
Where have you find your advance map?
#17
I just read the data out of your chart an put it into Excel, and then had it create a 3D graph. I skipped a few of the rows of your data so that the graph would have consistent 20% intervals. Note that the missing rows are basically identical to the nearest 20% row.

I currently run a HRC Ignition Module on my 1998 VTR, this is the second one I have owned, (this is the second VTR that I have owned so when I got this VTR it was imperative for me to find an HRC Ignition Module becasue I know how good it performed on my first VTR),
with the HRC Ignition Module you get an 1000 rpm increase in your engine rpm's (redline is now 10500 as opposed to 9500) and 4' of ignition advance and no sidestand ignition cutoff when the side stand is down while in gear,
the HRC Module gives you a definitive "hit" at 5500rpm's and pulls fast and smooth all the way to its 10500 redline, the rev limiter is "soft" and will over rev on downshifts and can cause problems like floating the valves, I know, I found out the hard way.
all in all, I too tried to track down an HRC Ignition Module when I got this second VTR, I went through Big Valley Honda with no luck but I did get the late Bob Hyashida's phone # and gave him a call, he said he didn't have and didn't know where to get one, then a couple of day's later he called me back and asked if I really wanted one, well hell yes, Bob actually had one, an authentic HRC Module and I asked him about the identification markings on the unit and they were complete, Bob sold me the unit for $400 which works perfectly with my ported heads and hi-comp engine.
