S-AFC vs Maf Translator

[Kracka]

I used both together and it worked out great. Using the MAF-T alone would get you by, but it would just be a rough tune. I used the AFC to make the small(er) fine-tuning adjustments.

The biggest injectors I would suggest with out a chip would be 650's/680's. With 720’s and 2G mas John's galant was at -46% or so (before the AEM) which, as you mentioned leaves you with very little tuning range, and was getting him on the wrong timing maps.

That being said, either one can take you a longway. John made 500+whp on a maf-t, AFC combo. He made more with the EMS though.
