New MegaSquirted m110 in a 280 SE

I while ago I was contacted by a person who had read this blog. He had a 280 SE -82  (w126) with the same m110 engine as in my car and asked me if I could help him to replace the engines fuel and ignition system exactly as I have done.
I invited him and last week he drove about 400 km to get some help from me to do the same. Before he visited me I asked him to do all the manufacturing and also mount the oxygen-sensor which shows the exact Air/Fuel ratio (AFR) while engine is running.

I only had my own engines AFR values from before I changed fuel system, so I was very curious how rich or lean his engine were running...
He filled up his gas tank before he drove to me and filled it up again when he came here.

1.22 liter/10km which is more than OK but he told me that he had been ”Eco-driving” the whole way and never had a measured a better fuel economy.

His AFR value while cruising the highway was as lean as 16.3 which surprised me because I've mapped my mixture to stay between 15 -15.5 when cruising. At Wide Open Throttle (WOT) he never got under 13 which in my opinion is way to lean. I have as rich mixture as 12.5 at WOT. I could notice that my car have much better acceleration than his car but with so lean mixture it was expected.

Unfortunately he didn't get his fuel rail in time so we only replaced the ignition in this first step but prepared everything for the fuel system swap. As soon as he was home again he called me and told me that his fuel consumption was 10% lower and this time he had really driven the car with high speeds and lots of kick downs.  He said that it was a totally new growl from the engine, much more responsive than before. This is exactly the same result I've got when I replaced my ignition system and at least 10% lower fuel consumption.

So now he waits for the fuel rail to be manufactured so that he can complete the rebuild.

I thought it could be interesting to know that it is possible to get a higher mileage and it wasn't only my engine that got good results from the swap...

Distributor disabled

New six coil

280 SE

Adapter for trigger wheel

Trigger sensor

Tuning...

Had to replace some damaged parts

Noticed that the car didn't respond on the throttle as it used to, found out that a bushing (called shackle by MB) was totally worn out which caused a gap before the linkage responded to a change when hitting the pedal.  Replaced the "shackle" and readjusted the throttle linkage.

Part number is visible on the plastic bags.

Part numbers

Upper part of the shackle is totally gone which caused a gap in the throttle linkage

New part in place, put it in boiled water for easy assambling

Shackle in place

Got some questions about the correct tire pressure, so this is what the sticker says on my car...

After this very long and cold winter it finally starts to feel like spring. I took her for a ride for the first time this year and she purred like a kitty.

Still, it's a little to cold for removing the hardtop but soon...

I want to wish you all a very Merry Christmas and thank you for visiting my blog here...

I haven't been so active this year since I had to spend more time with my family and other unexpected things in my life, but next year will be different and I have some plans for my car.

Hope that you continue to visit me ans see you all next year...

Uppgraded the car stereo.

Bought a new JVC car stereo to the car since I'm going to use it for daily driving soon, not very time typical but very practical and have a discretely look. It has bluetooth so I can connect my cellphone to it, stream music or take my calls from it (you can see the microphone near the tachometer). I will mostly use the usb port to play music from a usb memory instead of using those old CD disks which where always laying around everywhere.

Fixed illumination of Temperature wheels and Fan-knobs

Removed the plastic knobs to be able to replace the broken bulbs for the "Fan/Temp. knobs".
Seems to be ordinary standard car bulbs. Had one at home but will by some more tomorrow...

Plastic knobs removed

Now I can reach them

Standard bulb

Fixed the "shiftstick" illumiation

Replaced the auto trans. "shift stick" illumination bulb, had a really hard time finding one . Visited almost every car-part vendor but none to be found. 

Try Mercedes you think and that's what I did... They had one single bulb and couldn't get any more??? Fortunately I got one at least but since no more the be easily found around here I build one as spare using the old bulb and a high intense LED which is seen in the picture.

New bulb

In place

one spare rebuild one

Drivers seat finally reassambled

Finally... everything finished... started to assemble everything today.

Feels and look like new... Next is to put it back in the car so I can take her for a drive.

Finally reassembled...

Many stitches

Some new "soft" fabric glued on

Will it fit?

Almost there...

New flatheaded screws

Fixing the MB-Tex back piece

I have finally started to repair the back piece. It's not so worn as the seat so there are less to sew.
I have also ordered new "flat head screws" which attaches the back part to the hinges. It looks like they are made out of brass or other soft metal, probably to avoid them from snap of in case of an impact.

This is how it looked like, not so worn but need some stitches.

New piece of cloth glued on.

New stiches...

Drivers seat is now finished.

The seat really looks and feels great, definitely an improvement.
Had to reinforce the old clothing by sewing some new blue cloth on the sides, made it much easier since the "hog rings" now have something to grip on.

Time for the back piece...

Cleaned and ready to mount

Only the "plastic chrom" covers left.

Finally finish sewing the seat.

Put the MB Tex cover over the seats backbone.

Used "hog rings" to fixate the MB Tex cover, the pliers and "hog rings" at  the bottom of the picture

Tighten it up.

MB Tex seat repaired

The entire bottom of the MB-Tex cover was torn so I glued on a new piece of cloth to protect it from the Horshair-pad. Now I had to sew each stitch to keep the padding and ribbons stay in place...Took a couple of hours but at least the seat is finished now. Only waiting for the "hog-rings" I ordered so I can attatch the seat cover to the seats backbone. As soon as the seat is finished I will start with the back.

The seat to the left and it was more worn than the back piece to the right.

Started to sew using two needles, one fom each side.. Gives strong stitches ,same as from a sewing machine

Time consuming but easy since I use the old holes...

The middle stitches finished...

Finish, sparyed some glue over the stitches to fixate them.

All ribbons in place.
