hi all!

I stumbled to this forum after pondering different ways to tune my new to me 2000 golf tdi (ALH engine). I had previously found a site where someone had developed a full standalone ecu for these ALH engines based off an arduino mega. But I have recently decided it would be much better to reduce the amount of wiring and unknows and try to use to the stock computer.

Before about 2 hours ago i thought that modifying the maps of the ecus for my car was limited to programs that only larger companies had like malone ect. very excited to see there are other options.



as far as my background I got use to tunning on my first car a 95 civic eg with a d15b7 in it. the method of tuning was based on crome and datalogging done with free log. all ODB1 stuff so i was burning chips and swapping them out.

I messed with tunning for a while. then eventually swapped a d16y8 head on the d15b7. this netted a ~11:1 static compression ratio 1.5 liter this was quite fun for a while. I then moved onto building a 2.3 L turbo motor for the same civic. 2.3 f23a1 bottom end and stock rotating assembly, h22 DOHC head and eo 8 TD05-HR 16g and a equal length twin scroll header.


later i found myself commuting 50 km each way to work in summer and in rush hour traffic and the civic began to scare me with overheating and overall reliability. So i found a sweet deal on a 2000 golf tdi granted with 375000 km on it already but had been decently taken care of.

so i took it home did a full timing belt water pump on with changed all the filters and oils and got everything caught up. The main reason I began looking for this specific car to replace my civic is a project i did for a thermodynamics class in university.

This project included the thermodynamic analysis of a alh in stock form, essentiall stage 2 form higher boost pressure more fuel ect and finally how the previous two compaired to a compound turbocharged alh. this analysis showed that interstage intercooling with a stock vnt15 and a evo 8 td05-hr 16g at low pressure ratios resulted in a high efficency and relatively low stress on components. this is my ultimate my goal.

I am am going to be spending teh next few weeks trying to catch up on all of the new OBD2 stuff and trying to get familiar with all of the maps that i know have access too!
