From the archives. Dyno sheet from 2010. This is on the Emanage ECU.
Greddy Emanage Blue-
The crispiest ECU. Hanlded Idle like stock. very respsonsive. Wish someone knew how to wire up so that the full potential could be used. only the Map sensor and rpm signal were sent to the ECU. FE was very moderate at the best.
RD ECU-
lots of technical discussions available. Gave me a good learning experience.
FE was moderate at best. A wideband and some tuning could extract some power. But idling was not to my liking.
P28 with Neptune-
Chipped P28s were quite famous even at the time i installed the kit. lots of flavous available. neptune is a good option. Very famous on honda-tech.com. But the P28 is quite bulky in the stock form.
The only confusion was the choice of IACV. I suggested we use existing 3 wire stock IACV, convert to 2 wire IACV and connect to the ECU. Lots of information net. Joe told its better to go for stock 2 wire IACV. So got the same and installed. I think it was wise suggestion.
Hrtuning.com offers lots of support. After a while i found it supports bluetooth which i can connect to mobile app. So got the bluetooth module and got it installed at BW.
Initially i planned to go for tunerview RD-1 and make something like this.

But the pain of converting the fuel level to the display unit was a lot of effort. RD-1 elimiates the need for any gauge and what i see is what the ECU sees not the aftermarket gauge reads out. so its pretty safe to rely on the readings. Now HR tuning as released much sophisticated RD-2 which i beleive is kickass. But expensive at 700$. I think is worth because it supports a lot of other ECUs.

good things about Neptune
1- App support. Fully customizable mobile App with datalog. I have found datalog to be very useful and no need to carry computer. The App has pretty good refresh rate.
2. Closed loop tune gave good mileage. (Joe made a super diet tune with NA like AFRs) sometimes this irritates me.
3. stock harness used. Not even conversion harness used in my case.
4. Priced pretty ok at around 450$. Not so expensive given the features it offers. Bluetooth was another 40$. App license was ~20$.
headaches-
1. Had to buy 2 wire IACV at around 40$ or so
2. First P28 which we got was kind of fried. BW arranged another one at no extra cost.
3. The IACV is not direct fit on stock throttle body. So got a stock JDM manifold which eliminated the problems with IACV and got the injector leaks and other things fixed.
4. NOt a headache really - The tuning software is pretty elaborate. Can't jump in and tune.
Idling video- On a cold morning after a week of no usage. No throttle input given. Idling RPM is slightly on the higher side. Oil pressure take a little time to build up. This was not the case before. But BW tore down the bearings after a long drive and inspected for any signs of oil starved bearings. None found. Signs of an old girl?
I am happy with current setup. Can't ask for more from the ECU. And the mini GTR mobile App is worth every money spent.
