MAF Transfer Function Theory... - Page 2

I bit the bullet and went back to a Pro Racer Package. It didn't look like there'd be a Tweecer around before I got my turbo kit, so I went with what I know. This way, I'll be able to play with the tune a bit before I start installing things.

I also went with an SCT BA2800 for the MAF. The transfer function is known and I won't be screwing with load. I'll be using it in a blow-through configuration, so I'm hoping by going to the bigger MAF I won't peg it. I'm only looking at 400 or so with the stock long block and the turbo, so I should be alright. We'll see soon enough.

Good deal let us know how it works out.

Your answer to the first question is to scale the injector high and low slopes as well as engine displacement by19/45 = .45. Then start with the stock transfer function and tune from there. EEC4 cars dont have a good way to monitor load because you can't datalogg them with anything on the market YET besides a tweecer and you can't run a tweecer and SCT chip at the same time. Watch your MAF voltage and start from there.
