Bretts dynoplot

[mr detail]

He went back and looked at the dyno description. He said he copy and pasted the info from the Prelude so he had the descriptions the same but didn't notice it said TPS. He is not using a TPS mod only a MAP mod. We are using a TPS and MAP mod on the Prelude but I didn't get into that.

Ok, that makes sense. I saw "TPS" on the dyno sheet and it caught my eye as out of place. I know that JR's solution relies on the MAP sensor, but I was wondering if JR tried Rafe's TPS trick in a side-by-side comparison against a car with Oscar's MAP trick. However, as Rafe says, either trick shouldn't affect WOT performance.

That's what I thought.

Thanks for clearing that up Shawn.

Any clue as to why there's such a major difference between the A/F ratios of the two in the low end?

I know the 'box' in the second car was made to bring in the fuel even faster and that is what you are seeing. At this point I don't know how it was achieved. Perhaps the new 'box' was coming in before 0 vacuum.

OK Rafe here is the deal on the bottom end.
Brett's car has the MAP 'box' of the same design as our Prelude. Oscar said the Prelude fuel comes in real fast so the 'box' for that car was delayed in responding.

The one on the other car was made for the R so it came in fast.
