Why are you trying to change it? -1.94 is within range and is max timing for peak power. If you have GMTD then all you need is the tools to do it as GMTD can do everything a TECH1 or 2 can do.
;-) i only smile here - NEVER on pics - I have an image to protect ;-)
leaving lexington in 10 mins, next stop mammoth cave state park.
so tonight was the last night in a real bed ;-)
cannot update this thread so i will ask about TDC again in next locations :
mammoth cave, KY
Nashville, TN
Chattanooga, TN
Atlanta, GA
Savannah, GA
if all goes as planned ....
Any estimate when you mite be through this way, I'll be on vacation in Ms 4-3 thru 4-11 then back to Ga for work 4-12, my OBD-I stuff is there, I have never used it so it will be learning experience for both of us. Your I-10 route West also goes by my Ms house also so if we miss a hook up here, then maybe a hook up in Ms. Also Pepperridge, Killing Fields, and Dura-ration in the neighborhood there.
