I was attempting to set up sequential injection on my car today with the aem box (7m) and found that injector 6 wasn't firing (inj 9 output from the aem). I re-pinned the connector to inj 10, and it worked...intermittently at first, and then not at all. Now I figured this may be a wiring issue, so I switched the pins of inj 8 and 9 at the ecu, and switched phasing appropriately to fire 5 and 6 off inj 9 and 8 respectively. As a result, injector #5 (now firing off inj 9) was no longer firing. It looks to me like this is a problem with the aem, though I was wondering if anybody else had the same issue and discovered the problem.
Otherwise, back to AEM it goes. Fuck.
