VEMS at Volvo C70 5cyl turbo

We are a couple of guys doing our project work on The car electronics program(Bilelektronik) at Elof Lindälvs Gymnasium in Kungsbacka south of Gothenburg in Sweden.

The engine we should perform the VEMS on is a Volvo engine called B5234T3. 5 cyl engine.

We have got a lot of spare parts and also a nearly complete spare engine.

Well i'm going to keep you as updated as i can.

It would be nice if someone who has done the installation on this type of engine before could help us with some knowledge.


Maybe i forget to thank people who helps me with all this so i do it here. Thank you!

Summary

The engine is a B5234T3 (2319cc), From a Volvo C70 Turbo Compression ratio 8,5: 1

On crankshaft it's a VR (60-2 Emil?)

Camshaft is HALL

I made a shopping list with all the parts i think we gonna need and a price summary in sek (fill it up if you think something is missing) .


Trigger section

Trigger is the most important part to get right: if this is sorted, the rest should not be too hard (although everything requires some research and planning)

Trigger is very similar to 5cyl audi with aftermarket 60-2 wheel.


VE

Even if this engine is not very common, the head is the same as 4cyl volvo-s, so starting VE map can be borrowed (easy to tune with the wideband in any case).


Ignition table

of a similar 4cyl can also be used, as long as the compression ratio (CR) is close too. Good starting point should not be a problem anyway.


Wiring

Econoseal is worth its price, planning to use that.

RE: I saw that wiring is included in the econoseal18 harness and the econoseal36 harness or am i wrong?


From Tyresö Gym

Hello we just ordered our genboard and planning the wiring at the moment... we have a bit of problem cause the ecm harness is going thru a imobilzer module. Otherwise it have went well. When you order your genboard be sure to order it with the rigt options. Mvh Carl, Johan, Dennis, Christian, David FP3 Tyresö Gymnasium.

To get the correct options, you have to know:


Shortenings

Fill it up with usual shortenings and explainations if you want to.

VR - Variable Reluctance (swe. Induktivgivare)

CR - Compression Ratio

VE - Volumetric Efficiency (basically the values entered into the fuel map)
