Re: Project Underfunded / next phase - LSx carb'd to LSx efi

Well folks.......just like in the video...the truck was starting and idling but little else. I wasn't posting about it as I was beginning to loose faith with the harness builder, and to some degree the tuner. Well...I'm glad to say we finally resolved it. I had removed parts from our TBSS to swap into the truck for troubleshooting and felt like it was th pedal assembly. I finally removed the Interceptor scan gauge I had in the TBSS and hooked it up to the truck. It confirmed a issue with the pedal via a dtc, which was enough to get my tuner to send another pedal assembly. Plugged it in the evening and it worked! Was able to clear the dtc's also. This was the 1st time I revved it up since going to efi. Will need some learning or possible retune to clear a bog issue...and I'm hoping to be able to iron everything out this weekend and go hit the track!!! Since this trans should be able to hold it....I'll get my 1st full run out of it in the 1/8th. I may have a pinion angle mismatch issue...will need to investigate further tomorrow. How many degrees of angle can you have safely? Like 5* total or could it be higher....like 8*?With both yokes within 1-2* of each other?

I am ready to run this thing hard...just hope it's ready for it tomorrow...or I may be beating on a sick pony
