Hello everyone. I have been lurking here for a while trying to find answers for my 1990 suburban 454 TBI that I recently acquired. The young man that had it before me fought with it for over a year before he finally gave up and decided to sell it to free up his garage space. I found out that he had installed the wrong computer and that was causing most of his problems but I have found many other issues along the way that have been making it run better and better. Unfortunately I have run into a problem that I have not been able to solve yet. I have acquired a Moates APU1 and have began to data log. It seems that my .xdf and .ads files are not correct that I downloaded from Tuner Pro's site so I came here do download and try some more hopefully. I'm looking forward to learning more and possibly contributing to the group.

Thanks,
Matt
