M104 Mosselman twin turbo find! is ECU tune require?

[yao500e]

This is crazy guys,

I stumbled upon a M104 Mosselman turbo from a w124 e320 sitting and not driven.
The owner says he will sell it to DIRT CHEAP.

I already know it will install on my 1995 C36 M104.

Does anyone by chance know if Mossleman twin turbo requires an ECU tune or is stock ECU good for enough for maybe a 5 psi boost?

I'm not 100% I even want to go turbo route since I love the idea of keeping a C36 Naturally aspirated and running great as close to stock as possible.

Thanks for any information.

Stock ECU likely won't know what to do with boost pressure. Adding this on a 3.6L engine just complicates things. Try contacting Mossleman directly...

You need to read up on what is involved with adding a turbo to any vehicle. Reprogramming the stock ECU is probably not going to happen, so you would need to add a piggy back ECU inline with your ECU or. I did something similar with my CLK32k, it came with a module that wired to the MAF so the factory ECU didn't go haywire with the Supercharger. When I replaced the SC pully and added larger injectors, I also had to add a Unichip piggy back ECU, which needed to be tuned. The stock injectors were running at 100% duty cycle, so there was no way to get more out of the system without larger injectors, which ended up being too much, hence why I had to go with the piggy back ECU, to dial back fuel flow.

Your going to need to research the Mosselman. I don't know if there is something available that will work with the C36 ECU though, its different than the M104 in the E320

Hi, The limit for each version of the fuel head is not known but your target of 300 to 350 should be possible by controlling the stock CIS-E system

So i finally installed Dkubus FrankenCIS fuel management!

Hello 2phast, yes, if an ECU tune is needed, piggyback is probably the best way. to install a standalone is a huge project. to makes sure a standalone can do all the stock ECU functions will be a challenge. Not sure if older '95 C36 ECU has 'can bus' protocols to control gauges, AC, ABS, ASR or other non-performance functions, this will need to be researched to make sure a standalone can FULL REPLACE the stock ECU.

A piggyback is easier and can be removed easily too if needed.

But i have read and know turbo installers who install turbo kits with stock ECU for a light book of 5 psi and adding 50 whp or so.

In 2023, messing with the original ECU is simply silly for serious mods. Modern EFI is such a quantum leap over the original ecu tech that is like comparing a rotary phone to an i-phone. Piggy back was a band aid back 20 years ago. The same sort of idea goes along with the turbo chargers on these kits as well.

Talk to Matt Kwiek in Nashville as he is very capable in standalone for these cars.

obd1 ECU is pretty much impossible to tune. you have to open up the ecu and solder on a new chip. which is why a piggyback ecu is the only and most sinple solution. i have seem guys do it to w124 e280 cars and get pretty good results. the piggyback ecu just controls air fuel ratio, ignition timing, map sensor etc. The basic power tuning sensors. very basic but it does the job.

modern day ECU tuning is unreal and amazing. the factory ECU can do it but its also scary. lol
