WOT LH MODULE?
- Thread starter gasers
- Start date
Yes, that box has WOT enrichment. The US EPC shows this module as used on the 140, not 124; but someone posted on the forum a screen shot from a Euro version EPC that showed this module used in the 124 as well. I've got this module in one of my cars, it is functionally identical (as far as I can tell) to the other 92 500E modules.
BTW - welcome to the forum!
BTW - welcome to the forum!
Thank you! so it was worth 30 Euro then
I had this car for 10 year now and this winter i have mounted new cams 254* 10mm lift and also ported heads!!
I have just started up the engine and it sounds good i can tell you!!
The car also hawe Speedline c-bolt rims that i baught in 1995, and they are brand newe, never had tyres on before...

Sorry! no news yet....
Still waiting for the tuner to contact me for time to adjust the LH on rolling roads.
But i think the car goes really good and reach 260km/h FAST!!
With the new cams you loos some in the start but gain in the higher rpm:s...
It will be interesting to se how many horsepower it will tell on the rolling roads!

I was wondering if the early dual-spring setup would handle 10mm lift. Thanks for confirming! I wonder if the later, single conical springs can handle 10mm...?
Could you explain what "lachcaps" are?
Thanks!
NO! The dual springs conical spring does NOT work, 100% sure!
Aboute the lachcaps...if u regrinde cams the base circle get smaller and you must adjust that, otherwise it will be some millimeters play between camnock and the valve mecanism..the hydraul lifter cant adjust that much! so you put like small hats on the end of the valve to make it work.
I dont know how to explain better in English...anywone else that can maybee??

Bummer! Mercedes modified the cylinder heads for the E60 AMG camshafts with conical springs, to lower the spring seat, which allows for more lift. Guess the same would be needed with regrinds.
OK, I think I understand. Very interesting, I thought the hydraulic lifter would compensate enough for the smaller base circle.
Thanks!
Yes the lifters can compensate some but not as much as it needs in this case! the movment in the lifters is 3mm and its not enough....
In my engine the lifters was out 2,5mm from start. so i had just 0,5mm left to play with.
if i remember correct the base circle was taken down by 4mm in the exhoust cam and 3mm for the intake.
You know that exhoust cam was only 202* and intake 212* if i remember correct.....
I know from earlier tuning on other brands/cars that you can bay lifters with longer hydraulic elements and then you dont need "lachcaps"
Are you planing to do the same?

I was interested in performance camshafts from Hagmann or Dbilas, as described in this thread. (Side note - I need to see if I can copy these posts about the camshafts into that thread.)
The information available on all of these M119 camshafts is somewhat incomplete, and the Hagmann camshafts are no longer available. I would probably be using these cams on later engines with conical valve springs, which complicates things. Hagmann stated the conical valve springs had to be replaced but they didn't say what springs were to be used. I've never seen dyno graphs showing the power gain with the custom camshafts, and I also don't know if a custom EPROM chip is required to maximize the gains, as Hagmann says.

I think its a "must" to do a custom EPROM... now i can feel it goes lean!
And i can say with my cams it maybee does about 30HP, hard to tell....
Ofcourse there is no problem to make cams that have more lift and so on
but then the ideling goes nuts, and left breaking at stoplights is a must to ceep
idle at right level and thats not what i want.
Abowe 4000rpm the car mowes like crazy and the power loss above 5500 is gone))
I really hope my tuner calls soon so i can see on dyno...

Gasers, please can you do some pictures and videos about your camshaft mod and post them in this thread: http://www.500eboard.com/forums/showthread.php?1000-M119-aftermarket-camshafts
So what is you timing/duration and max. valve-lift? I think a tuner can adjust/probably make the idle better by changing fuel amount at idle.
I have yet to find a non-expensive LH-Tuner in Germany/Europe that can make chips without having to visit their dyno.
Something like Eurocharged, which i will be using for my M113K tuning.
Thank alot, Christian.

30hp gain at high RPM would be great. But I need to keep the idle decent... can't have a car that won't idle. Strong power from 4000-6000rpm would be perfect. Please keep us posted on what you find out from your tuner, and if you could get dyno graphs, that would be great!

Hi
I checked the partnumber on my LH control unit, it is 016 54514 32, is this a WOT module?
My car is built late 1994 ( 1995 year model ) so it should normally not have WOT if not PO have replaced it to a module with WOT.
And are 016 54517 32 and 016 54562 32 also WOT modules?

None of those module numbers have WOT enrichment.
No module with a part number that starts with either 015- or 016- will have WOT enrichment.
FYI, 016 54562 32 is a 6-cylinder module for M104, and will not work in the 500E.
Gerry's screen shot of the EPC for .036 specific LH Modules was great.
Seems like a screen shot of the w140 LH would be helpful, even if it doesn't really state which are WOT.
With a screen shot and a shout out of, "below 014-__-__ doesn't have WOT", would clear up some of the confusion.

Were there any updates so far?AT LAST!!!
My tuner called me yesterday, so now i go on dyno and adjust the LH module
It will be intereresting to se if the cams did anything to the HP!
I will come back to tell more after dyno is completed...
Anders.
Can you please say something about regrinds in this thread here: http://www.500eboard.com/forums/showthread.php?t=8054
Thank you
Got it! 014 54517 32 is factory fitment on the later build 1992 500E's. Also with WOT enrichment. The 014 54517 32 is 036-specific and pretty rare... hang on to that one.
Dave my 500E of '92 has also this LH module with this number. Could you explain me what the benefits are having this specific module ?
I have red that having WOT enrichment is not something people want in general.
WOT enrichment simply provides a few additional horsepower when the throttle is mashed to the floor -- it stands for "Wide Open Throttle (Enrichment)"
It was found on 1991 and 1992 model year production 500Es, and (for the US market) was phased out for the 1993 model year.
It's a common "performance upgrade" for people to put a WOT LH unit in their 1993 or 1994 car.
You will never notice it unless you are flooring your gas pedal all the time.
Yes, it is desirable.

In addition to what Gerry said... the 014-545-17-32 module was not used in any other chassis. I have no idea why, or if there is any benefit to the 014-545-17-32 (not likely). Most other LH module part numbers are shared between either the 140 or 129.
When the 500E/E500 were originally made, there were specific LH units/part numbers specific to the 124, 129 and 140 chassis. Over the years, MB has superseded all of the individual part numbers down so that the official part numbers for the 5-liter M119s with LH injection are all shared between the chassis.
If you haven't seen it, there is more information on the part numbers for the LH units (and other CAN computers) on this Wiki page:
Pardon me, as I need to finish re-creating this page, but it DOES have all of the relevant information for the LH units. I need to re-add the other information for the other CAN computers.

014-545-17-32 definitely has WOT enrichment. It's an omission/oversight on the Wiki page.
The latest EPC only shows the "last" part number specified for most chassis with LH modules. However, old EPC's as shown below, display the old part numbers with supercession chain. Second image has the footnotes.

The WIki page has been totally revamped and all missing information re-added.
Yes, it has WOT enrichment. And, the EPC / XPISS shows this module as replacing the 014-545-17-32 which originally was installed in late-production 036's with WOT enrichment (i.e., late 1992 USA model year). VIN break for Euro-spec cars shown below in EPC screenshot:
Thanks !
