Seen it. Cool, but at the same time, way more expensive and complicated than dropping in the M113.

Can you please tell me how you did those headlights so beautifully?!?

 

I wet sand them with 800 grit, moving up to 1000 grit. I then buff them out with a 1/4in right angle die grinder with a small wool compound pad with 3M Imperial Compound. Then just a couple of coats of wax.

I built fiberglass boats for many years and it's the same process you would use to finish gel coat. Plastic is plastic.

Jared

 

Is this OK to use a 2K clear coat on headlight lenses?

 

Have never tried it, so can't say if it is or not.

I just use the compound method. I typically have to do my Jettas once per year.

Luckily, my red XF has clear bra on the head lights and they are still crystal clear.

Update:

Car is still running great!! Have about 600 miles on it since the install and have gone through almost 3 tanks of gas!! Just can't seem to keep my foot out of it.

I did a little cosmetic work to it today, bought a replacement wing for the spoiler and got it installed. My original spoiler had a big chunk of paint missing and the paint was bubbled at the edges almost all the way around.

While changing out the spoiler, I realized my rear emblem was really close to falling off. Some 3M PSA trim tape fixed that.

Jared

 

Nice. The cutting board has been destroyed. But on the other hand, a good job.

 

Some goodies I was waiting for showed up today!!

Just waiting for my rear brake lines.

Jared

 

I decided to share some of my "Economic Stimulus Check" with Rob at Needswings.

Just placed the order for my Cat Delete mid pipe.

Can't wait to hear what the exhaust sounds like sans cats.

Hello Jared @lotsofspareparts ,

I am an Indie MB Specialist, who has just got my own project Car running, an SLK R170 RHD M113 V8 conversion

I have finally, after months and months managed to get my account here sorted and can now see, (and have read your entire thread

I want to thank you because you have likely answered an issue I've had, which looks like I have well been overthinking my recent issue, and may well be nothing more than old Spark Plugs which need changed. You have confirmed that I used the correct ECU and converted it, which has been bugging me

Could you please tell me, on your ME2.8, does it say Q02 or Q01 etc on the top left of the silver Bosch sticker ?

I won't bore you with the details, but I have had a lot of misfire codes, with my Q02 V6 Modded ECU, but on another (Q01) ECU I don't get that issue, but this ECU being a V8 ECU from W220 has other issues like I have to crank it for extended period via a hot wire to starter, but once it fires up it runs and drives OK without misfire codes, and boy, that Engine sure isn't misfiring !!
My current theory is that Q01 ECU has less tight tolerances on it's diagnostic monitors and so doesn't pop the codes, where the Q02 V6 ECU does, and as the W220 history is un known could likely be nothing more that dodgy worn out spark plugs, which I will be pulling out later today

Our 2 stories done at approximately the same time, (I started my conversion just weeks ago), apart from your cooling fan solution, are almost identical

I had another issue which involved a bit of serious DIY Engineering, being RHD I had to relocate my Starter Motor to the Left Side, where the stock V6 one was, guys, with basic hand tools that was a hair raising time, but ingenuity prevailed and the Engagement is perfect !!

I did everything exactly as you did, like Ex manifolds, Wiring etc

I used a 2.87 C Class Diff, (straight swap) plus I bought a W220 S500 with ME2.8 as my donor, so I also used V8 Trans and custom coded (just Diff Ratio and proper manual mode TCU / TCM lol

I couldn't afford a pro ECU job, but I'm pretty handy with that kinda stuff, so I built my own ME2.8 ECU, by using R170 V6 ECU, and like your guy I added the 4 Extra Mosfets and the 4 extra SMD Resistors. Mine started first time, basically because I cloned the Epromm file from the original ECU. (my car was still in use when I built the ECU ).

Pix ..............






My thread is here :- https://www.slkworld.com/threads/slk...roject.533795/ over 600 posts as I started it when I bought the Car Dec 2018

 

Awesome, keep it between the lines.

 

Car looks great!! I would like to find an SLK just to have.... or for the wife to drive.

My ECU states "Q05". I've included a picture.

Jared

 

Hi Dave302

Congratulation on your conversion. I don't think you have a problem with the ECU hardware. What Firmware/Maps did you put into your V6 ECU and what version coding have you used? ie. I don't think you've set up your modified V6 ECU properly. You need to do more than add 4 components and clone the 5P08C.

 

Hi Jared @lotsofspareparts ,

Thank You for your kind words and the pic, that helps, I think that as your Car doesn't pop Misfire Codes on a Q05 (revision ?) then mine should not do so on a Q02

Hi Andrew @CL770 ,

Thank you for your reply

You might be just the guy who can help me here you obviously know what you are talking about on this.
I am noted for being long winded so I was brief in my first post about what I did, as a noob to this Forum I didn't want to bore you all

Bear with me a little, I'm gonna try and bring you up to where I'm at ..............

BTW, in case it helps I am a 58 years old Petrol Head, I started working with cars at age 12, apprenticed as a Mechanical Engineer, and then ran my own Auto Trans Specialist Company for many years, then I sold up and relocated, now I run a small 1 lift Workshop next to my house, specialising in Diagnostic and Rectification on MB's and other Cars with Dealer Level Kits plus most tools on the planet, I have (4 different) SDS Kits, as well as Kits for most other popular marques.
I am noted for getting in a pickle sometimes by seriously over thinking things and missing the obvious on the odd occasion !!

I am somewhat Electronic Blind when it comes to understanding what component does what, same with Hex and programming, but I am gradually learning bits and pieces as it is really essential these days.

I am happy to share any details of all the cool stuff I did on my Car, as well as stuff that doesn't work, with you all, like using an MB PWM Cooling Fan and getting my custom 3" Air Intakes past the Steering Reservoir plus plus plus anything and everything else

I will be honest, this is the first time I've gone this in depth with an ECU, so I am still learning, I even built a special bench in the workshop with Soldering Station, KTag, Variable PSU, etc etc and practiced a lot on old EBay ECU fodder, and tested out stuff on the running R170 SLK V6 and V8 W220 Donor Car before I finally took both the Cars to bits a few weeks ago ..............







Back to the Car :-

The Engine does not Misfire detectably, and I am experienced around V8's and V12's It runs on all 8, but the SLK V6 Q02 ECU will pop Misfire Codes on anything other than very light throttle / low revs, (below 2000 rpm), where you can drive it for miles and miles.
The V8 ECU's Q02 and Q03 do the same, always # 5, # 6, # 7 # 8, plus an occasional # 4, so mostly left bank, and when it pops these Misfire Codes it shuts down those Cylinders.
The V8 W220 ECU's Q01's, never ever post Misfire Codes, (120 mile round trip is the longest so far), and with these 2 ECU's my Car goes like an Exocet Missile, and Traction, Transmission, Dash Cluster (200MPH SRT - 6) all systems work perfectly as they should, (Speedo over reads by 10% with AMG 180 MPH guts in it), yet to address that one.
Obviously the Car will not Crank on that ECU, have to use a hot wire to starter and after a few goes it fires up, and also no Cruise / LIM, but other than that it drives perfectly with no issues !!

Being brutally honest, no matter which ECU I use the idle quality is not quite as good as my other Car, a W220 S Class with M113 5.0, but no the SLK isn't on 7 or anything like that !!

As said, the 2 W220 Q01 ECU's I have tried do not post misfire codes, hence my current theory that Q numbers mean tighter wound Diagnostic Monitors and my Engine may have a slight fault that the Q01 doesn't see, where the others do............ Yes, that's a pure frustrated guess right now, but no one so far can tell me what Q01 , 2 , 3 etc means, so right now it's as good a theory as any.

OK here's what I did ECU wise :-

I Started with a V6 320 SLK ME2.8 with part number A 112 153 27 79 / H/W 04.02 / FD02M07 / Q02 , this was identical to the ECU on my V6 R170, absolutely identical.

I soldered on 4 Mosfets (same ID numbers) from a good working V8 ECU. I then added the 4 SMD Resistors, 3 on top side and one of which is on the underside of the PCB, these were the only Hardware differences I could see between SLK V6 and V8 ECU, (ignoring the Crank / Cruise / LIM Hardware that the V8 doesn't have).

I wrote, (cloned), the V6 SLK Eeprom 5P08C File into this ECU, (I have also tried Virgin and SDS Initial Start Up procedure as well).
I wrote the V8 W220 Engine Maps into the Flash File.
I left the Micro ST95040 File alone, (although I have tried cloning the V8 one as well)

Version Codings ...............

I kept them all exactly as M112 V6 R170 ECU, except ..............

E50 Motor Coding

600W Temic Fan

2.87 Diff

I have also looked at all the V8 W220 Version Codings and again all the other Codings are identical except EIS Not Present, which was and still is set to Not Present in the SLK R170 "V6 to V8 Franken ECU"

Now I'm really really praying you can spot something here and tell me what I done wrong, or agree with my current lines of work, which is Spark Plug replacement just because history un known, (when my dumb factors actually send me 16, instead of just 8 that I received on Friday lol), and if that doesn't work I will test the Mosfets I added based on comments from another guy, and instructions how to test 'em.

TIA, Cheers Dave

 

Hi Dave

It looks like you've got the right equipment. We should be able to get it working properly. I'll send you a PM, there's a few things we can try out.

 

Thank you

 

To @lotsofspareparts ......

Hi Jared, would you prefer if I continued about my issue on a new thread, or carried on here on yours, not sure of Forum protocols etc and how you feel about that ?

Cheers Dave

 

Knock yourself out dude, I don't mind at all.

In the grand scheme of things, it pertains to what needs to be done to perform the swap, no matter if its an SLK, or a Crossfire.... which is also an SLK lol.

Jared

 

Thank You !!

LOL, yup

OK, So after a fraught week or 2 and with some serious help from a member on here, (he knows who he is BIG HUUUUUUUUUUGE THANKS), my R170 SLK V8 is now sorted, Cranking / Cruise and LIM all working as it should, and absolutely No Fault Codes after running it out for 3 trips, circa 100 miles so far, it is running and driving like a dream, so next up is all the little jobs on my "Snagging" list ....................

Things like removing the odd modified bracket and painting it, a little Heat Shield for a PAS Pipe, a few more P clips etc etc

Having got this Car sorted after a couple of weeks of Head Scratching it felt exactly like the day my Divorce came through .................. This big cloud of doom has been lifted from above my head

Cheers guys, back soon Dave
