Alright... well I found a shop I liked here in South Florida with a Dyno so I said what the hell, Let's see what she can do. So I made an appointment for 2pm, loaded up my extra ECU and rode out.

It was $50 for three runs but the guys there where real cool and gave me a 4th run free so I could compare my two ECU's. I ran a JDM Spoon P13 n/a and on a 55 shot N20 and a P28 with an H22A program tuned by RPT both n/a and on N20. Although the P28 does not control the secondaries this tune was supposed to compensate for that short coming.

The engine is a 1994 JDM H22A mated to a 1995 USDM H23A 5-Speed.

Here is the list of non-stock mods on the engine at time of Dyno:
- Magen ceramic 4-2-1 headers.
- Bomz high flow cat.
- Bullet 2.5" mandral bent cat back exhaust.
- MSD SCI-L ignition amp.
- Crane Cams fireball coil.
- eBay powder coated short ram intake.
- Zex dry nitrous kit (55 shot).

I think that's about it, everything else about the engine is stock, no stupid breather elements or trottle body coolant bypasses.

All the passes where done in 3rd gear and at 7200 rpm.

Here we have the P13. N/A in Blue, N20 in Red:

N/A = 177.6hp and 147.4 ft. lbs. of torque
N20 = 217.4hp and 192.4 ft. lbs. of torque

Here is the P28 with the RPT H22A tune. Again N/A in Blue, N20 in Red:
http://www.josebellas.com/images/dyno/rpth22ap28.jpg
N/A = 181.7hp and 149.6 ft. lbs. of torque
N20 = 216.5hp and 197.3 ft. lbs. of torque

So there you have it. The P28 with a good tune can preduce some good numbers over a Spoon chipped P13.

Definetely decent numbers...

thanks for sharing the info...it's always good to see real dyno plots from real people in reference to parts/setups.

Who did the retuned P28 rom? RPT? you have a link or a #?

Well I chipped it myself and had the rom emailed to me. Just had to burn the bin to an eprom and chip the ECU.

Well I edited the P28 bin this morning and switched the Vtec to engage at 4600 rpm. The transition to Vtec now is real smooth hardly noticeable. You can feel it slightly and hear it in the exhaust. Before it was like the car would lose momentum and then when Vtec hit is was super loud and pulled allot. But now I guess I'm catching the low cams right where they fall off so the transition is not as noticeable. I hope to get it back on the Dyno today and see what it looks like. Maybe also get some afr plots and a high speed run ;)

It's actually quite technical and beyond the scope of this forum but if I where to summerize it, Then I'd have to say because it was free, lol. I just used it because a friend of mine let me have it for free so I said what the hell why not use it.

There is a difference between the USDM and JDM gear ratios. I think the USDM's are actually geared shorter then the JDM's, why I don't know but if you would like to compare Prelude parts visit this site : http://www.preludecrazy.com/index.php?redirect=specs/models.php That is an accurate collection of all the Prelude knowledge you'll every need.

Crome, I've got full throttle launch already to. I may head over to the Dyno in a few or tomorrow. I have to manage my time here.
