OK so do it right, give me the spark curve you want and I'll mail you a chip for $50. How far are you from CDA ID? bring it here and I'll tune it right in person completly for $150. Or spend $150 and learn to do it yourself... you'd be set to do it over and over again.

I honestly don't know how to do it the wrong way? Somehow you have to get the EST module to send a signal to ECM to fire injectors, then you'd have the vacuum and mechanical advance from stock motor firing plugs. You can't just use the signal from the Duraspark as it needs to be a 5 volt square wave signal to ECM or you will fry the ECM, the EST sends the correct signal... so maybe that could be done?
Thanks for the offer. I guess it is probably time to learn to tune these, Is there a page on here that details what I need to get started?
