I'm new to the forum and this is my first time to ever run a standalone ECU so be kind
![Laughing :lol:](./images/smilies/icon_lol.gif)
I'm currently converting my w201 190E to M111 from a CLK 230 Kompressor, I'm quite a long way into my build and i have the engine fitted and running on the CLK loom and ECU. The engine was running perfectly however the clutch was slipping as the dual mass clutch and flywheel I fitted didn't suit my Getrag (dogleg) gearbox.
After some research I was advised to get a single mass conversion kit for a Mercedes Sprinter which I did and now the car drives in all gears fine however the engine is in limp mode (no boost) and it is a bit lumpy which it wasn't before. I'm putting this down to the crank pickup being different as its the only component that I have changed that could influence how the engine runs.
After more research I discovered that anyone else who fitted the single mass conversion kit also was running standalone ECU meaning they could change the crank trigger on their ECU which I cant do. This means I need to go standalone now to resolve the issue and I'm looking at purchasing a Hellen 128
The questions I have are
Is the Hellen ECU plug and play?
Is there a base map on the ECU to get my car to start and run?
Can I tune the ECU myself with a laptop? (I've never done anything like this before)
Do I need to change anything else when I fit the Hellen ECU?
Any input is appreciated
Regards
Marc
