Brand Specificity When Using OTS Maps

Ratman · 06-29-2006, 01:42 PM

I have a question about OTS ECU maps and protunes as they relate to turbo upgrades. In this case, my question refers to Cobb Tuning's 18G map that they say is specifically for use with a FP18G. From a business and product perspective I completely understand why Cobb would specify one manufacturer for this map.

My question is: How much, in practice, does the turbo brand matter? (I know they are all assembled from the same parts). In other words, if I were to get an 18G from another manufacturer with the same housing and wheel size could I be reasonably assured that it would run well and safely using the Cobb map? Would it make a difference if one is ported and the other isn't? Aside from these variables, what else do you look for to ensure that one turbo is similar to another? CFM maybe?

I know that optimum performance on any turbo is achieved by a tune, of course. I'm trying to get a sense of how exacting you have to be when choosing a turbo and using a standard map like the one offered by Cobb.

I've been following Cobb's development of this map for awhile. They did not specify a specific turbo because of a brand allegiance. It is definitely a variability issue.

It makes perfect sense to me why Cobb would specify one brand, and I don't doubt they did it for the right reasons. My question is more along the lines of for my purposes as an end user how much it really matters.

It will make the difference between boost being controlled and not, basically.

Sounds like it could make a big difference then!
Thanks for the input

I agree, that's looking like the best way to go
