LH Module?

[kre8tive202]

Ok here is the update....It worked!!!! Replacing the LH module worked, TICKING is gone. Gentlemen, I can now definitely hear my fuel pumps as on the old LH module I had in there, I could not hear the fuel pumps. SHould I be concerned? I havent swapped out the fuel pumps yet (I have new ones).

You can check eBay. They pop up there periodically. A LH module (fuel injection computer) front a 1992 car with add ~10-15hp (at the crank) on 1993-1995 cars.

hmm..I thought 92 was cis injection and 93 was efi..

W124 V8s were all LH injected

In 1992 only the R129 500SL had CIS-E injection.

kiev is correct, all years of W124 M119 had LH-SFI. More info at this link.

I have one available.

 

[Rico nelor]

I have one available.

Will this work for my 93 500sl??

 

[Rico nelor]

I have one available.

What's your price, sir??

Any LH computer for a US 5-liter LH-based car will work for 5-liter LH engines on the US-spec 124, 129 and 140 chassis.

So would a 4.2 take a different type of LH-module? Or did 5.0 have a different LH?

The LH module is different for engine displacement. 4.2 modules have different fuel mapping than 5.0 modules. Also, some modules don't play nice in other chassis, in particular the 400E/E420 will exhibit some bizarre shifting behavior if the wrong module is installed (this is due to the first gear cold upshift relay, which is only present in USA/Japan spec .034 chassis).

You can use any M119 LH module, any displacement, for testing purposes... the engines will start & run normally in the driveway with a "wrong" module, but you want the correct module for your chassis for normal driving.

Oh okay gotcha, so then the 6.0 has a different type of module than the 5.0?

Yup! The 6.0 needs more fuel.
