NEW - Specific SEB ECU Version for permanently disabling the E-DIFF on the Ferrari F430 - Scuderia - 16M

Since specialized workshops encounter more and more failing E-DIFF differentials (internal hydraulic pressure losses, internal hydraulic leaks mixing with the transmission oil, air leaks entering the hydraulic system, worn friction disks, hydraulic fluid contaminated with differential metallic fillings, random E-DIFF errors, etc.), they asked us to develop a simplified version which permanently disables the E-DIFF whatever the Manettino position is. The cost to replace the entire differential is prohibitive in terms of parts (complete differential #238598 - no individual spare parts) and work hours (transmission out repair). In this case, they and their customers prefer to fix the issue by disabling entirely the E-DIFF, remove the hydraulic hoses and plug the holes at the differential and Power Unit. The E-DIFF ECU itself can also be removed as it will not used anymore.

With this specific SEB ECU version, the E-DIFF will never be activated anymore, no errors will appear on the instrument panel and the car won't go anymore in limp mode because of E-DIFF issues. That's why this SEB ECU version does not have a remote control unit and also does not have the wire harness towards the E-DIFF ECU. It simply plugs directly on the E-DIFF wire harness which has been unplugged from the E-DIFF ECU.

If you need to permanently deactivate the E-DIFF, then this specific SEB ECU version is the right option for you.

Another testimonial from a German/Italian customer who had constantly F1 issues (jumping in neutral, gear misses) where we diagnosed the root cause being the E-DIFF (internal hydraulic leaks). Since he installed the SEB ECU, no more issues at all and he could even upgrade his tires 235 front/295 rear without any issues affecting the E-DIFF. Thank you Tony for sharing your impressions (y)

"I came back from holidays. I traveled with my Ferrari about 4000km since I installed your SEB-ECU. I have not had any problem... both with the Manettino in SPORT position and in RAIN position even with front tires 235 and rear 295 the car goes beautifully. Thank you so much for helping me solve several problems and with all your updates it has become a modern Ferrari of the latest generation. Thank you so much ..."

and from a USA 2009 Scuderia owner:
"Very easy install! Turns out I don’t like the Ediff at all and prefer it disabled for a more consistent feel. I didn’t realize the “twitchy” feeling while turning was the Ediff trying to help. You seem to really go deep on the electronics on these cars!"

SEB - SMART E-DIFF BYPASS ECU installed on a Ferrari 430 Scuderia. This car as many others had E-DIFF issues causing the F1 to fail by lack of hydraulic pressure.

We had also another case recently where a Swiss official dealer installed the SEB ECU after having diagnosed an important internal E-DIFF differential issue on an owner's F430. The SEB ECU put this car back on the road, no more issues.

If you have a Ferrari F430-Scuderia-16M, you really should consider the SEB ECU (E-DIFF Bypass ECU) as already many owners did.

Unfortunately, the E-DIFF system will not last forever and when it fails, it gets very expensive to repair, if repairable. That's why already many "Permanent disabled" SEB ECU versions have already been installed by workshops to avoid the entire replacement of the differential. Every week, we hear from workshops where the E-DIFF hydraulic fluid leaks into the transmission oil.

At the other hand, the pessimistic constant "braking" E-DIFF deprives you of what really a Ferrari should be...

Set your car free, make your F1 happy and save your E-DIFF for when you really would need it! It's 100% Plug & Play and installs in minutes.

When disabling entirely the Ferrari F430 E-DIFF system, we recommend to remove both IN and OUT hydraulic hoses, the solenoid valve and the pressure sensor. The hydraulic hoses can be easily and entirely removed from the quick couplings at the Power Unit side. It's important to disconnect or remove also the E-DIFF ECU.

We offer now a kit of 4 specifically manufactured blanking plugs made of high quality A4 stainless steel. Each blanking plug is equipped with a specific Viton high heat resistant O Ring seal (-20°C to +200°C).

Hi Stef,
Also fitted the E-Diff Bypass ECU and all is good. If I fit the E-Diff blanking plugs, how much ATF must be left in the diff?
Is the Pressure sensor circuit part of the E-Diff ECU? Thanks, TONY.

Hi,
Great you installed the E-DIFF Bypass ECU, thanks. Once you remove the E-DIFF solenoid valve, almost all hydraulic fluid (or ATF) will flow out, there will be very little left.
Yes, the E-DIFF pressure sensor which is wired to the E-DIFF ECU is also part of the items that can be removed, then plugged with the smallest blanking plug. The kit has all 4 plugs you need to plug off all holes safely:
  • E-DIFF high pressure blanking plug (IN) - Hexagon 19mm
  • E-DIFF low pressure blanking plug (OUT) - Hexagon 17mm
  • E-DIFF solenoid valve blanking plug - Hex socket 10mm
  • E-DIFF pressure sensor blanking plug - Hexagon 14mm

Yes Tony, I recommend to leave some hydraulic fluid in the differential, not much is needed, just a bit enough to keep the internals getting dry.

Hi Stef,
But from a reliability point of view, is it necessary to leave some hydraulic fluid in the diff ?
Thanks, TONY.
