Brancher un volant Sega Model 1 ou 2 sur un driving force Logitech

I have pins 1-3 and 5-7 bridged where U7 should be, is that right for normal operation?

Also, should R3, R4, R5, R6, R7, R8, R9, R10, R15 be 220 ohms or 220k? There is conflicting information in this thread!

Yes.

you must use 220 Kohms resistors.

It all seems to function correctly and I set the pots at 20v and 12.5v but the clutch is very soft.

Try to put a 10uf 25v capacitor between output clutch and ground.

The 10uf cap did it 

WOW it's powerful!! I'm going to have to play with the settings but it works great, thanks!! 

I'll upload a video soon to youtube with the results.

Thanks again aganyte

One more quick question, the feedback is very strong in one direction but feels a softer in the other. What should I adjust to fix this? The strong direction actually feels too strong, like the clutch is locking up.

As I understand, I should be keeping the pots at the same levels?

You can adjust the power between right and left with rv2 or rv3, be carefull, you must never adjust under 12,5v.

...et ce surtout et essentiellement sur PS2 que je ressentais avant de moddé le logitech
Vais essayé de remplacé R1 et R2 retiens au jus

toutafé , j'ai racheté un logitech exprès pour faire la comparaison. Sur Outrun2 PS3, le comportement n'est pas le même. Et j'ai l'impression que c'est sur les effets. Il y à un bon choc sur les cônes complétement atténué avec L2M2

[Iro]

All the feedback effects seem to be correct, just very weak.

Does the capacitor has resolved this issue ?

[aganyte]

J'ai un gros doute sur la fréquence de coupure du filtre passe-bas en entrée de la carte L2M2, avec R1 et R2 à 3Kohms, cela sera peut être meilleur.

Yes

They are both already at 12.5v exactly.

It sounds like the clutch is locking completely as there is no "washing machine" sound when I turn the wheel to the right and it's very hard to turn? It's fine when I turn left.

Adjusting RV4 doesn't make it much less powerful on that side.

[aganyte]

You don't understand, 12,5v on Rv2 and rv3 is the max power. If you up voltage on rv2 or rv3, you have less power on right or left.

Si quelqu'un peut expliquer ça en plus clair 

[RetroRepair]

Aaahh got it  

That's for clutch power?

I will have a go at adjusting them then  

[aganyte]

That's for clutch power?

Yes, Rv2 and Rv3 give power to clutch (one for right and the other for left)

[RetroRepair]

Ok well RV3 works fine but RV2 doesn't change anything  

I changed it for a new pot and still is constantly at full power. I need two hands to pull it all the way round!! It does measure the correct 12.5v when I adjust it.

I guess something is blown or incorrect with my circuit. It couldn't be due to the 10uf cap on the clutch output?

[aganyte]

Try to change your lm324.

[RetroRepair]

I already did that, it's the same
