Smoth cells after Veal.

[Hank Rearden]

I have already a well tuned ve table with veal, bike runs great, but VE table has some sharps peaks and deeps. It is correct to smooth cells after veal? Any experience? Or beeing a high power, high rpm engine it's the way it was meant to be?

The recommended approach is to run VEAL and then manually smooth out the map, and repeat. You may take a few steps back on having a well running engine after smoothing initially, but after a few iterations should produce a better VE map in the end, and likely a better running engine.

I'll do, thanks. Seems that this engine needs a lot of fuel at midrange on wot, much more than at high rpm wot.

Sounds about right - it's going to do some of its deepest breathing just above the flat spot, then the torque slowly trails off. The power at the top end is pure revs.

I see, this is how it looks.

This is my first project, I leave my msq, suggestions, comments, are welcome.
The software, this forum, has been great.

Sometimes earlier VE peaks in the wot cells are where VEAL is adding extra fuel because Accel Enrich is not adding enough.

But accel enrichment must be disabled when runing veal, right?

My understanding is that, accel is filtered by VEAL and does not need to be disabled. Under any circumstances, I keep mine enabled......

Correct, you should not disable AE, it is filtered.
The residual effects of poorly tuned VE will impact the table tuning some. VEAL will still try to compensate for the AE error. But if you shut AE off completely there will be a large AE error that makes the condition much worse.

Ok, I'll run veal with ae and see what happens.
What i saw is that, at least my bike, needs very few accel enrichment.
A made lots of runs and kilometers running veal, in fact, it is almost not making more corrections, always with ae disabled, and bike runs almost perfect, (already way better than carburated), and it only needs very few ae at light (fast) open throttle low revs, and at wot high rpm. So, or veal has made an excelent job tuning the bike or bikes needs less ae (less weight, less inertia, etc...) or I'm lucky

Manual saids RPM based AE is for high sprung or race engines, motorcycle supersport engines qualify for this?

Compared to a cage engine? Most definitely!

Then, it is ok to try it . It is also filtered by VEAL?

Hi Hank,

I also have a GSXR Turbo tunning microsquirt. I didnt realize untill this thread that AE could be used while tuning either. I always thought it was the last thing to work on.

I would very much like to see how you have set yours up and compare notes. I cant get your msq to open so would really appreciate some screen shots of some of your menus and tables. If you fancy chatting you can email me at brisbanejack@hotmail.com

Cheers and good luck with your project.
