Installing Vems3.3 on a Volvo 244 with a B21ET engine. Taken out the dreadful K-jetronic to get complete control. This car should be competing this year in the Benelux Driftseries.

My name is Jochen aka Brickdrifter and I'm living in Belgium.

Current setup:

B21ET

Garret T3.60/.63 trim turbo

XS Power intercooler

36-1 trigger wheel with Ford VR sensor

IAT sensor from webshop

Volvo 960 TPS sensor

1.0.45 Firmware

Megatune, no LCD :-)

Raised idle with solenoid

Vems Serial nr.: 547 controls:

- injection (2banks)

- ignition

I've connected signal wire to EC18-pin3 and ground to EC18-pin2.

I don't get ANY reading on Megatune. Tried advancing ignition, spanner on block or even loose sensor and hitting that with a spanner. I'm wondering if the connection is right.

Is there someone who can make some sense out of this knocksensor recording? I would like to know the knock frequency. :-)

All well so far. Then I changed ign_crank_advance to 15° and the timing light showed 24°. What am I doing wrong?

The most likely problem might be the timing-light: with wasted spark it will have a wrong idea of RPM and angles. It is theoretically possible to compensate (nontrivial calculations easy to get wrong), but best to

  • use a cheap timing-light that flashes at the time of the spark, without offset
  • if you have a fancy timinglight, use it in a mode where it flashes at the time of the spark, without offset
  • If you only have a TDC mark on the engine, note that you can quickly change advance to 0 degrees for testing, just apply a bit more throttle and issue command "mda01", engine will run much slower and manifold etc gets very hot in the long run. After finishing, mda00 returns to normal state. //Emil
Thanks to all for the help.

Primary trigger settings - mine differ to yours:

Mine:\nÿ1ÿ

You seem to have:

trigger_tooth=00 and another_trigger_tooth=12

tooth_wheel_twidth2=0A and reset eng phase...

It might be worth patching your settings with these and setting up again.

22-10-06: Tried but no difference. With this setup the engine only runs ok with ign_tdcdelay set in MegaTune to approx. 60° with the whole ign map set to 15°.

Again, I triple checked that the engine is in TDC when the mark says so and timing light shows zero when crank-advance is 0.
