ok. thanks.

So i just bolt on the Bosch Coil to a metal bracket to the chassi, no problems?!


hooked up the bosch coil and J702 unit tonight.
2wires for input from Buchka WS Board, 2wires for output to Coil, 2 wires for 12V Switched power and Ground and 1wire connector for the Tachometer. installing it all behind the firewall is the plan. completely removing the wires forward to the original coil and ignitionmodule. Will try this on my FK engine before installing the 16V Turbo so i know it works as it should :D excited!!!

just put togeather a complete HOW TO hook it up guide in pictures at this link now will put togeather a video later on to see. it works amazing! i think even that my engine is pushing more power now thanks to the wasted spark system... just ripped the grip on 3rd gear with my tuned FK+M90 in my 242 on the freeway from 70-140KM/H continously spinning all the way up. Amazing stuff :D

if any inputs, please give it

hi Boris
in theory it should not matter, airmass = airmass, regardless if it is measured at atmospheric pressure or at boostpressure. I am not really sure if it works that way in practice.
the benefit: shorter distance between airmass measuring point and ignition/injection points.
This should make for faster response to changing throttle inputs.
the downside: the AMM might gets contaminated by oilmist coming from the turbo and crankcase ventilation. (clean more often?) This contamination could throw of airmass measurements which could cause bad AFR's

well... my AMM is running quite well this way, and it is a common way to do it here in Norway, althoug i guess it is a 50/50 split on how many run it like this or lengthen the AMM wires to the Turboside.
no problem at my car like this. and i am using a separate oilcatchtank so that will take up some of the unwanted oilmist before reentering the turbo intakehose.

My AMM is also there in my 940. computer seems to respond a little faster and i was able to put a non recirculating BOV between the intercooler and the AMM without having any problems.

Edit: When and if these ever go on sale again I will be picking one up.

I got my engine running with the mod, but it doesn't run well. I have checked wirings, changed sparks plugs and cables, tested that there's spark in every cylinder. Seems like bad timing or something..?

What should I try next?

Do the AMM's not heat to 1000 degress for 3 seconds after the car is shut down to burn off oil deposits or contaminated air??? I remember reading in the green volvo manual and haynes manuals that they do.

kiroileva_fossiili has a bad board. He's getting a replacement.

This is not at AMM thread. Please keep it on topic.

I'm having the exact same issue. I've hooked it up before but kind of ghetto, and had the same issue. Then I took the time and did my wiring with nice copper wires and waterproof electrical components just like kodja shows in his tutorial. Exact same issue. Although I have not checked for spark, the video posted above is 100% exactly what is happening to me.

Any suggestions on what to check?

Then your board was fully vetted before it went out. The problem should not be with the board.

I had a problem where my car would barely idle and wouldn't rev out at all. turns out it was a bad solder joint on the ground wire to the BuchkaBoard.

Thank you sir. I'll probably check this out again this Sunday. I haven't rev'd the car long enough to actually get it start, but it turns over just like the video above posted.

can be found in your local volvodealer. or ordered there not expencive either!
Figured I'd add to this. Not sure how much the dealer charged,

It's also known as a 3 pin AMP JPT connector.

Also the bosch 2x2 can be found on some Land Rovers, 2003-2004 I believe. So the coil and connector could be found together at the junk yard.

This drawing is very helpful, but just to confirm, BOTH the 12v to the ICM and the coil should be switched, correct?
If so, are the existing 12v to the stock ICM and coil suitable (switched)? Thank you! (Hoping to get my board soon!)

Launch control clarification question... Will the engine RPM be limited to whatever it is when SET is momentarily grounded? If so, does grounding ARM, or ungrounding ARM release that hold?
