FS: LH module w/ WOT enrichment for 1993-95 W140 S500

I have an extra 1992 LH module for sale, from a 500SEL. This module will give 1993-95 models with the 5.0L engine (S500, 500SEL) at least a 7hp gain due to the WOT enrichment (I think the actual gain is closer to 10hp, but this will probably vary depending on your particular engine condition). The 93-95 modules do not have WOT enrichment, they remain in closed-loop operation, which is better for emissions but not so good for power production.

I've been using the W124 '92 modules in my '94 E500 for years now with zero problems, as have dozens of other folks with W124's. The WOT power gain is real and tangible, I've proven it on the dyno and at the dragstrip, it's not one of those cheesy chips which make grandiose claims but do precisely nothing. There is no loss in fuel economy, btw, normal operation is exactly the same, the module just richens the mixture at WOT to boost power. The module I'm selling is for 5.0L W140 through 1995 only, the 96-up models use a different injection system.

I always make sure the modules I sell are in perfect condition:
  • All old DTC's (error codes) cleared
  • Adaptation reset to mean (factory) values via digital scanner
  • Tested in my car to verify that it works perfectly
  • 100% ready to install in your car
  • Guaranteed not DOA.


$325 free shipping in the USA (lower 48 states). Email me for international shipping costs. PayPal is fine.




Best regards,

Is the part number the same on the '92 500E (W124) modules as for the '93 S500 (W140) modules?

Nope. The 1992 and 1993-up modules are different part numbers, and almost all W140's use different part numbers than W124/R129 due to different programming (with one exception, I believe, for a certain '92 module).
