-This page is a collection of pages we're putting together to document ECU damage and repair concerns. ​ We often receive ECUs that have significant corrosion from caps leakage or have severely botched socket jobs.  We want people to see these pictures so they can evaluate their own ECU before it's even sent to us.  We're hoping this will reduce the shock factor later when the ECU arrives here and we have to break the bad news. 
  
-If you see that your ECU has problems, contact us offline to arrange for an estimate and/or repair.  ​

-Generally speaking, we have to get the ECU in here to do an estimate. ​ Estimates by e-mail just aren't practical because there are too many little things we can't see and not everyone sends decipherable pictures anyway. ​ So expect to have to box the ECU up and ship it in if you want us to provide an accurate estimate.
