Title: Vtec stopped working on ecu
Post by: d112crzy on March 30, 2009, 05:14:47 PM

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 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?

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.
