there is absolutely nothing out there that is truly good to tune your ecm
im working on a flash tool but it will take ages to complete at this rate
even when its ready it wont be a thing you buy in a box that just works
its an obscure 2 year only ecm that people never made cool stuff for because the ls1 was just around the corner
thats why so many people plug the obd-i ecm in there and call it a day
