1991 VR4, 10:1 compression, mildly ported heads, stock turbos, 3" downpipe, 98 SL flashable ECU
I just read through all 16 pages of this topic, lots of good info. My display comes on at first, but then comes on and off, mostly off. Pulled it out last night to check things out. The capacitors have leaked, diodes 6 and 7 don't look too good, looks like R38 is still good. I'll do some testing and see what I can do with it.
