Wolf 3DV4 which is the version before the V500.
I tuned this myself, I have put all sorts of ECU's into boats/rally cars etc and had no issues getting them going and tuning them. The Wolf however, was a pain, the documentation is shocking so it took me a week to get it firing on all 6 cylinders. It also seems very sensitive to low battery voltage. I run Haltechs in my other boats.

Time for an update.
Now running a 2JZGTE with a Holset HX52 on E50 and around 23psi boost. This setup is good for around 155km/h. With a bit more boost and wings on the front of the boat we should get to around 180km/h, time will tell I guess.
The motor gets a pretty hard time in drag races like the Hamilton bridge to bridge race where we are sitting at 6100 rpm (640hp) for 9minutes without lifting, a lot of heat is generated! Intake air temp still sits around 35-40°C as we have a massive water-air intercooler with plenty of cold water.

Much more interesting river racing especially near the end!
