Thanks to Dieselgeek and the poobahs at EFI Source for their help getting our LT1 project going with the (formerly Spectre) EMS now sold by EFI Source.
Scott had the patience to troubleshoot with me for hours when we had some goofy miss that would act like a rev limiter around 3200rpm. Traced everything down and couldn't find the problem. Ended up taking the wiring harness back off, laying back out to make sure the tach input wire was nowhere near the injectors (could be picking up noise) and also swapped headers as the header flanges were right on the spark plugs and wanted to make sure they weren't grounding out. Whatever we did worked and the EMS performed perfectly. It uses Megatune as the software and is SUPER-easy to tune with. We used an LM1 to eyeball by itself and also a narrow band hooked up to the EMS. Timing and fuel changes were almost instant. We used GM sensors and an LS1 Hall effect pickup with a hall effect trigger wheel from the defunct Holley Anhililator line.
Again thanks Scott. Look for an upcoming story in PHR...
