FIXED FIXED FIXED!!!
So I went out there this morning with the idea of swapping in the B15 ECU and seeing if it would start. I figured if it started then I had F'd up my Calum RT or there was a loose connection in my step-down harness. I knew it would want to die because of the VE TB and especially the E60 MAF but if it turned over I should have my answer. Well, it started with the B15 ECU. So now I figured I had toasted my Calum. I decided to unplug the B15 ECU and one more time try the Calum ECU. Well, it started so I figured it was just some loose wiring. I tidied up a couple of connections and the car runs. Funny thing is for the first time my VE is kinda quick!!
I got the exhaust hole after the cat welded up and it sounds and runs much better now. Once again I love my exhaust note!!
Long story short I will probably be making another step-down harness to have as a back-up just incase. I will use what I learned from my first one and make it better.
It's funny how such a negative can turn into a bit of a positive!!
Now I just have to put my dash and the rest of my car back together.
Off to see a tuner guy tomorrow to hopefully tweek the tune and fix some trouble spots in the maps.
Scrildo Do you have any suggestions what I can use for switched 12v power, for the wideband, under the dash while I ave it apart? I want the wideband to receive no power until the car is started??
Thanks everyone who responded in this thread!
