Well, I have had a look at the Mugen pre-tuned ECU and I know that the AFR is a flat 12.8-12.9 right the way upto the limiter.

I'd expect the Amuse to be similar, but i'd still bank on running in the low 13s as the ideal AFR

 

ohh, this is AP2 with F22C right???

 

Yes, this is an AP2

 

I hope he doesn't mind me speaking for him. One of our clients, mr flannery77, just received his Amuse R1 Titan, R1 cat, and R1 exhaust manifold. He is going to dyno his car, install the parts, then dyno again (all in the same day) later on this month. I know that for starters, his entire Amuse setup weighs only 43 lbs. Since he doesn't have the ECU I don't expect 25whp gains, but he will be posting his results in quite a few places here on S2Ki so keep an open eye and an open ear for him!

Because a lot of tuner's just copy A/F ratio and call it a day.

 

Cool, sounds like an awesome setup!

 

That's correct, I'm going to do my best to have pics, dyno results, and possibly video posted before the weekend of the 28th is over.

 

Video would be cool, this system is going to sound sick!

 

Shouldn't it all weigh much less than that? The R1 weighs in at like 4.5kg if I am not mistaken, the mani about 5kg if I remember correctly from holding mine and I can't imagine the cat weighing more than about 3kg being that it is made of Ti as well (at least that is what I heard from Tanabe-san when I ordered my mani, in fact they told me I wouldn't see nearly the gains with the stock cat in place), so that right there is just under 29lbs.

Is your R1 the resonated version, if not, take off a couple more pounds as well.

 

Yes it is the resonated version. I kind of wondered the same thing about the weight, but Hunter did say they weighed everything when it arrived. I want to say that some of it was still in the box when weighed. That could have something to do w/ it, but who knows?
