So I have a p75 that I converted to vtec. It worked just fine for a few days and randomly stopped working. No CEL's, I've tried it on 2 different cars where I KNOW the wiring is working properly. The ECU works just fine except there's no fucking vtec. $:-\$

What/where do I need to test for continuity? I've already gone over all my solder contacts.

I've never had an ecu that did this shit.

Never mind

Reading owns me

Never seen it happen without throwing a CEL. C60 pops = CEL. Q26 pops = CEL. C14 missing (never seen one pop) = CEL.

Do you have p28.pdf?

D11 backwards?

That fries C60 as soon as you let off the gas pedal, throws a CEL. It might fry other stuff, but only seen C60 go up like a small firework.

I thought it was C60 as well, so I replaced it. I had originally used one of those blue capacitors from a bad ECU, then I just replaced it with one from a 11f0 vtec conversion kit I had. Still the same problem.

JD, no I don't have a p28 .pdf.
