the problem when tuning above a "clamped" sensor is...........the car cannot properly fuel the car in all circumstances............can it be done sure......but it always ends badly
With a user ID like "OldBrokenWind", I should expect comments like this ---
Did a little more research and discovered AFR is AKA "Lambda". Maybe "AFR" is too easy to understand / communicate? I didn't see it originally because I didn't expand the data log chart columns to show complete headings --- getting lazy in my old age! One more bit of knowledge to file away.
Anyhow, my Ziptie map is running AFR's between 11 and 13 --- a quick 2nd gear run. My original Perrin map is a little tighter between 11.5 and 12.5 --- a longer 3rd gear run.
Been running 25PSI for about a year with a Jeff Perrin remote tune --- no problem. The pair of FCD's don't let the ECU know about the excess boost. But, there are other factors, like MAF, that won't match the ECU boost readings. That's why I was pushing hard for another dyno run.
I'm still not running my new map --- trying to get used to the new turbo. When I switch to the new map, what do you think I should be watching out for? What will a "bad" AFR cause? Think I should data log a quick run to check AFR?
