I have spent the past 6 months tuning and tweaking a Mexican Beetle 1600i running MS2 courtesy of Mario at The Dubshop.

The engine is a low mileage original factory engine with all stock FI fitted + a Wideband sensor and a 35mm merged exhaust.

I thought it would be helpful to post my tables now the car is running pretty sweet - feel free to do the same if you have a similar set up as I struggled to find any tables for the Mexibugs.

I have also attached a MAP in case anyone needs a base: https://www.dropbox.com/s/2067461rimrpl ... i.msq?dl=0

Thanks for that.

I'll have a look and see how they compare to my tables.

Mine is running well but hasn't been on a rolling road yet.

You have the same engine?

Post your up - I'd be interested to see them too. Mines not been on a rolling road either.

I have a standard 1600 twin port engine that was original carburetted. I have converted it to run with a single throttle body but with port injection.

This is my spark advance table. It is basically a reproduction of the mechanical and vacuum advance curves in the OEM distributor. No spark tuning has been done yet.



This is my AFR table.



I am wary of running the engine too lean so I have been very cautious with the AFR values.

Interesting.

Have you tried my map to see if any of those tables work better for you?

No. Its a UVA Fugitive sand rail and Its laid up for winter now. Once it's out again I'll give them a try.
