Sim's 1979 Volvo 245 Snot Rocket Wagon (7th)

The Snot Rocket

My name is Simeon Veldstra. I built the seventh FreeEMS powered
ECU to run an engine.

The engine is a 1979 Volvo B21A. It is an inline four cylinder
with a single overhead cam crossflow head with two valves per
cylinder. It displaces 2.1 litres. The engine was fitted with a
SU side draft carburettor and a points and condensor ignition
system. The engine is supposed to produce 100hp in stock form.

The engine came with my 1979 Volvo 245, and is still installed in
it. One of the smaller cars on the road today, it seats seven and
you can close the tailgate on a refrigerator. It's a lot of fun
to drive.

The EMS I built uses the Tech Arts card and a board I made by
hand. It's pretty ugly, but it works well, and was fairly easy to
build.

I swapped the distributor for an adapter that drives a DSM Cam
Angle Sensor and added four coils from a GM LS1 V8. The car is
now running sequential ignition and likes it.

Once the ignition is all dialed in, the next phase will be
building a pressurized fuel system and swapping the carb for the
intake manifold and fuel rail from a 1989 Volvo 740. I will add a
board to the ECU, sandwich style, to control a JBPerf P&H board
to drive the injectors.

Waiting in the wings is a TD04-15G from a 1995 Volvo 850...

The debian project http://debian.org runs my computers and
helped me understand the value of free software.

The folks at http://turbobricks.com have been a source of good
knowledge and an endless waste of time.

This thread badly needs an update! Also, you don't have a users' rides thread! All the chatter went on in DIY HW section. Keen for suspension updates which would be out of place here or in DIY HW.

Re lack of users' rides thread, I remember now that that's partly (wholly?) my fault. Sim's users' rides thread turned into a DIY HW build thread, so I moved it. Unsure what the best solution to that is. Suggestions from Sim welcome.
