Hi.

I am a guy from Denmark and I am the lucky owner of a 93´FD (there is only 3 FD´s in Denmark)

My 93´fd cuts off the engine in about 5-6000 rpm when i am on a dynojet. It looks like there are a problem with the ignition, but when i drive on the street there is no problem. It never cut off in the streets.

I hope someone can help me with that problem because it drives my crazy. ( I have brand new spark plugs so that is not the problem)

The last time i tryed the dynojet it shows 290 hp before it cut off by 6000 rpm. It boost with 0,85 bar or 12 psi

 

What are your mods? How are you controlling boost? I have the same problem but it's because I'm running too much boost and the stock ecu is just cutting the fuel.
