Amuse vs Toda Header.

For a normally aspirated car, on my dyno, with my wideband in the tailpipe, we shoot for mid 13's. Interestingly enough, just putting the Mugen ECU in an otherwise stock S2000 puts the ratios right there (Mugen did their homework).
When Prolene came back with the Toda, the ratios were as lean as 15:1 in some areas.
With respect to a stock ECU car, we usually see ratios in the low 12's across most of the range, dipping into the low 11's near the rev limiter.

UL/Prolone,
u had indicated that Prolone is running a Mugen ecu which pretty much holds mid 13's A/F across the board......
If this is the fact then why did you see 15:1 A/F ratio after he installed the TODA headers. Is it because the dyno test was done almost imediately after the Headers were installed. If this is the case, how long has Prolone been running the headers, has the ECU 'learned' the new map adjustments to satisfy its mid 13 A/F ratio target? and if this is the case has Prolone dynoed again.......
Thanks

The Mugen didn't learn. The header probably didn't alter part throttle mixture much at all. But at full throttle, where the ECU does not learn, it did have a profound effect. Remember, the Mugen ECU is designed to work with the basic Mugen products. If something creates significantly more airflow (say the Toda header, or an AEM/Injen CAI which has some airflow spikes at low rpm), the car will run lean.

This is all great info! I am truly enjoying this thread.
From what I've heard so far, it sort of brings up the point, is it better to stick to one company's product line where you're assured the parts work well together, vs trying to mix and match a bit of this and that where you essentially either hit or miss?
I'll admit I've done much of the latter with my rx7 for years and spent upwards of $150k to know that sometimes the rewards can be higher trying to mix and match, but for most practical applications, sticking to a pre-configured system would yield the...how should I put it...less headaches, lessens the chance of running into problems. And I only say "lessen" because I honestly feel you will NEVER totally eliminate problems no matter whose product line you go with.
This is all very good stuff, finally a forum that "shares" info.

Oh be assured that everyone shares. all you have to do is get the right people interested and ask the right questions....Unfortunately their are alot of members that merely echo.......
In my experience, Mixing and matching products, is very rewarding if you 'know' what your doing. Unfortunately, since the S has only been out for not many years, the knowledge base for this car is so little, I myself have done so much trial and error testing with several products. The outcome is not what you would expect many times. Also, price of the product also have nothing to do with what you would expect. And more importantly, the tested or claimed HP have nothing do with what you would expect. Most of these claimed HP are either tested on a stock S or an S that has different mods. So unless you have exactly what they have .....never expect the same gains......

Prolene has been running 100 octane for a while because the Mugen ECU runs a lot more timing and a lot leaner than stock. Since Prolene has been known to track the car "occasionally", the 100 octane is a good safety precaution. You'll have to ask him about detonation, but on the dyno, and when I've driven his car on track, I never noticed any.
