100% of 440's? Didn't see that coming. I assume you have seen near stock dynos? I have seen 9.7-10 under boost from TCCS. Those cast pistons seem to be a problem. Maybe we need bigger injectors with the Lex meter if you can rewrite the timing.

3p141592654;2014784 said:Yup, there is no limit, and it's easy to scale for larger injectors which takes care of the 100% duty cycle problem.
I guess my point is that with the stock 440s, fuel cut really is the end of the road. You need bigger injectors if you are hitting fuel cut, there is no software fix for it.
Scaling the AFM is tricky, because there are over 30 tables that use load as an index. Besides the big timing and enrichment tables, there are also many smaller ones that trigger off load and they all get messed up with Lex mod. But the good news is they can all be fixed.
Also, by looking at the 1UZ code we can definitively say that the Lex AFM flows 28% more air for the same frequency than the stock AFM. That makes it simple to fix things up. The real problem is that timing and enrichment tables stop at 78% load. After that the value is just held. Filling out the table at higher loads would be a good thing to do.
