Thanks for the kind words guys! I'll try my best, don't want to be "that seller" who takes money and doesn't wanna know you afterwards...

that looks really good, can't wait to do mine! hey what paint or coating did you use on your intake and dizzy housing...how did you prep the surface?

PaulD_944S2

HFB, can you tell me what you used to mount the coil pack over that cam gear housing front?

H.F.B.

That’s powder coated. I still have the rest of the dizzy housing and the camshaft housing powder coated on my shelf, but still didn’t get around installing it. You see meanwhile it's a bit dusty.
Preparation was sandblasting.

H.F.B.

In stock I had the rest of a 5/8” Aluminum Plate that I milled according to the measures of the coil. Then I drilled 4 holes through the dizzy housing to bolt it down.



Here are some more descriptions.

H.F.B.

Just for you to know. Today I tried to update the VEMS firmware and this procedure killed my Ignition Coil Drivers. But, probably this is just related to the VEMS Stealth Kit and not representative for the stock kit.

The update took around 10-15 min + config check etc. After that it smelled a bit weird in my cockpit. See pics.
So never let the ignition on longer than 10 min without running the engine, it could kill the driver.

I will install two new transistors and additionally a HEATSINK.

Here you can see the difference between the stock and the stealth kit.
Stock is with heat sink and Stealth without. This could explain the problem.

one question
How did you use the original ignition wires to the coilpack?
Did you swap the sparkplug end or the coilpack end?

H.F.B.

I just swapped the Spark Plug Connector. So I could keep the wasted spark ignition coil connector and wire that was included in the stealth kit. This was the easier way for me.

I have to explain as I already did to henry over email regarding ignition drivers and firmware updates. The procedure specifically states that disconnecting coil and injector plugs (or pulling their fuses) is mandatory. Failing to do that may fry outputs.

Heatsinks would not have saved the drivers sadly in this case and I have tested VEMS configurations for years, the heatsinks are not required for most cars.
