IONI Firmware; Everything After 1.6.1 Terrible

Thanks, I’ll have a look when I can.

What games are you using, and what types of driving situations the feel is worse?

Thanks Mika,

It’s Assetto Corsa (the only sim I drive). It’s just generally in the corners.

Also:
Mige 130ST M10010 with 2048 SinCos

Hi Mika,

Have you looked at the drc file?

Also, is there much discussion about this with the IONI people? It seems like filters get added to the firmware, & there is nothing the end user can do about it?

Edit: or maybe it’s not filters?

Kind Regards

Nothing special was found in that DRC file. So far, I haven’t been able to find any explanation to your reduced feelings.

It’s got to be filtering surley?

the mmc and mcc shouldn’t be the same , also the mms is way off. what’s your psu ?

Good catch, I wonder why I didn’t notice this.

@Emmett_Scully: Having the MMC and MCC at the same value, reduces the headroom to produce “peak” forces in cornering. I suspect that you are hitting the MCC, and it won’t let any spikes larger than that because your MMC is the same, thus clipping the force output.

For some IONI firmware versions, having the same values for both of these made the drive not init, but I believe it has been changed for the latest versions.

also mms is way off , 1000 should be the set and not 65000

he should change the values of mcc and mmc , if he tells us his psu we could help and then recalculate mr and ml because 9,078mh seems way off.

Out of curiosity what should my mcc and mmc be set to if I have a small mige simucube and ioni hc with a 480PSU? Sorry to butt in but I just wish to check my settings are correct.

MCC for example 10.5 A and MMC at 12.86 A.

MMC 12.86A like Mika told already

Although i don’t own the small , theoretically MCC for 10nm of rated torque should be set at 6,428A

Thanks everyone for the suggestions, I’ll try these over the next few days

Also, the power supply is an Antek Inc PS8N48. which is 800W linear unregulated. The values were obtained using the auto function in Granity
And I don’t think I’m clipping, becasue I have AC set to 50%

your psu is top notch . The settings you are using on the other hand are not.

fft = 20 sec , fev = 500 and fmo = 500 ? really ? also setting the mpp higher than your psu’s watt is not optimal.

try these:

Goals tab
BDD = 1
BED = 1,500

machine tab
MMS = 1000
Mcc = 6,250
Mmc = 12,860
Mr = 2,744
Ml = 8,601
Mtc = 2360
mpp = 800

fault limits tab
fuv = 25
fft = 0,500
fev = 30000
fmo = 0

i mentioned only those that needed changing. mr and ml are only examples , after you hit apply for the new settings , use the calculator to get the new values and then re hit apply.

Hi Loukas,

I tried your settings, they made no difference apart from make the wheel much stronger. I think I prefer the MMS being 65000 also. Can you explain this parameter?

Anyway, the 1.7.1 firmware is really bad, it’s like the steering goes light, not free, but light, & I loose detail, and ability.

Tonight I was driving the F2004 around the nurburgring. No matter how many times you get blown away, you never get sick of it. What an awesome car, and wheel.

But with the 1.7.1, I was loosing a lot of strength at different parts. Turn 4 for example, I could not feel the front tyres, & was never able to make the apex. There was less feel at the chicane also.

Going back to 1.6.1, it was actually much stronger overall, & I turned the MMC down to 11. It still seemed a bit stronger than MMC=12.86 on 1.7.1.
And it’s the MMC setting which sets the strength, so what is MCC ment to do?

OK, so now I’ve tried the latest Simucube firmware, with the 1.7.2 ioni.
It’s much different again, this is the best one I think.

It’s still a bit weaker, I put it back to 12.86 on the MMC. But I’m not loosing any feeling, turn 4 was no problem, & the steering was solid again on the way into the chicane.

I wonder what’s going on?

Mms should be set to 1000 rpm to match your servos spec.

Have you tried simucube 0.9.10 which has the latest ioni?

Hi Loukas,

Maybe over the next few days, if not, next weekend

Ok, I’ve been testing a bit with the 0.9.10, 1.7.6 combo.
This is very good now, I didn’t do a direct comparison, as I’ve come off a 2 week break.
But driving the F2004 around the Nurburgring, there seems to be more range than ever before, self aligning forces are smoother, and seem to have more of a gradual build up, in a way that’s more realistic.
The forces also seem more fluid; before there seems to be some noise, in that they were not as continuous as they should have been.
Very good detail in slow corners also.
