DS Question

[Sweet6]

What cells tell you that you might have an exhaust leak?

Im not sure which cells you are referring to, but it sounds like BLM's are what you are asking about. I dont know that you would necessarily find an exaust leak making drastic blm changes. Something like a vaccum leak or otherwise would cause a problem with the blm's, but not an exhaust leak. I cant think of any way you could pinpoint an exhaust leak with DS, except with maybe slow spoolup or something odd like that. Perhaps someone else can, though.

Someone told me a long time ago, that certain cells on the BLM would indicate that you could have an exhaust leak. Someone on this board reviewed my DS file and said he thought I had an exhaust leak based on my DS data and sure enough my DS header was cracked. I just fixed my DS header and wanted to use DS data to verfiy my leak was gone.

Generally speaking...If cell 0 is far off from 128+/- and the rest are close to being in line, it can indicate a exhaust leak. Compare a old DS file (with the leak) to your new DS file (without the leak) and see if any of the cells are askew. If you still have a leak (it could also be the crossover seal) the car will spool slower and run richer at idle.
