I got a 98 d16y8, and im wondering if i can just swap a P08 ecu, so that i can get higher revs and such? will it work properly?

Here's a bad-*** list of honda ecu's and where they came from:

All Honda ECUs have a part number which is located on the side of the ECU and inside the ECU on the connector. e.g. 37820-P72-A01

The part number consists of three components:

* Honda's part number for ECU, which is always 37820
* Three characters (which are loosely related to the model of car/engine). e.g P72
* Three characters (which are the revision of the ECU) e.g. A01

The middle three characters are the most useful to identify what the ECU is. Different generation ECUs may use the same characters. e.g. a P72 OBD I ECU is different from a P72 OBD II ECU. Here is a list of common ECUs:

* PG7 : 86-89 Integra (86-87 vac advance, 88-89 electronic advance)
* PM5 : 88-91 Civic/CRX DX
* PM6 : 88-91 Civic/CRX SOHC Si
* PM7 : 89-91 DOHC ZC (JDM 'EF' ECU)
* PM8 : 88-91 CRX HF
* PR2 : 89-91 ZC (Euro)
* PR3 : 89-91 JDM B16A EF8/9
* PR3 -J00 or J51 : 92 JDM Integra B16A EF8/9
* PW0 : 89-91 JDM B16A EF8/9 DA6-XSi
* PR4 : 90-91 Integra LS/GS
* PS9 : 88-91 4 door Civic EX Auto
* P05 : 92-95 OBD-1 Civic CX
* P06 : 92-95 OBD-1 Civic DX
* P07 : 92-95 OBD-1 Civic VX
* P08 : 92-95 OBD-1 Civic D15 JDM
* P0A : 94-95 OBD-1 Accord EX
* P13 : 93-95 OBD-1 Prelude Vtec
* P14 : 93-95 OBD-1 Prelude Si (non Vtec)
* P27 : 92-95 OBD-1 EG JDM Civic 1600 sohc
* P28 : 92-95 OBD-1 Civic Si/Ex
* P30 : 92-95 OBD-1 DelSol DOHC Vtec Si/EG SiR
* P54-G31 : 1997 Honda Accord 1.8 LS
* P61 : 92-93 OBD-1 Integra GSR
* P72 : 94-95 OBD-1 Integra GSR
* P72 : 96-00 OBD-2 Integra GSR
* P73 : 96-00 OBD-2 Integra Type-R (JDM & USDM)
* P74/75: 92-95 OBD-1 Integra LS/GS
* P75 : 96-00 OBD-2 Integra LS/GS
* P2N : 96+ OBD-2 Civic HX Coupe
* P2P : 96+ OBD-2 Civic EX Coupe
* P2E : 96+ OBD-2 Civic DX Coupe
* P2M : 96+ OBD-2 NZ Civic SOHC VTEC
* P2T : 99+ OBD-? Civic Si Coupe
* P5P : 97-00 OBD-2 Prelude Type-S (JDM ECU)
* PBA : 97+ US Acura 1.6EL
* PCT : 98+ JDM ITR / CTR
* PCX : 99+ OBD-? S2000

[b]To answer your question, a P08 ecu is from a "92-95 OBD-1 Civic D15 JDM".. Just keep the P2P that you have in your car. You don't need to rev any higher unless you're motor is modded for that, and you can make power past the stock redline. They just get an EMS.

The Y8 doesn't make much more power much past 6500 - it'd be useless to extend the redline.

Not to mention it'd be dangerous to the bottom end of the block....if you don't float the valves first to do an entire fuckery of the engine.

You'll have better ET's shifting at 6800 or so - the Honda tach runs about 600 RPM too high at the redline, so shift at like 7k on the OEM tach and that's probably your best bet.

If you want a more optimal **** point you're going to have to get a more accurate (aftermarket) tachometer and then dyno your car to see where the power drop off is.

my buddy has the 92-95 gen of the D15b vtec, and his vtec just pops so hard, i was thinkin with a swap of ecu's i could possibly get the same result.

sohc vtec popping hard??? hahahaha sounds more like torn motor mounts

and that list is a tiny bit inaccurate... i have a straight d16a vtec which is like the z6 and sohc zc vtec, and its run by the p08 as well.

Haven't you heard man? Swapping to a p08 ecu makes your vtec pop HARD. The P08 is the hardest popping sohc vtec motor right after the Z6!!!!!! best bet is to swap it in. It might not plug in right away so you'll have to cut some wires, but its only like one or two wires for the "hpv" solonoid (hard popping vtec.) Its only found on the d15b vtec and z6 good luck

Does anyone have a P08 ECU for sale? I have a JDM D15B and the person who did the swap has a P2P ECU in the car and the automatic transmission won't shift out of 2nd, and the speedometer isn't working. I replaced the VSS sensor, undid the battery cables for 15 minutes started it didn't touch any accessories or gas or brake let it idle for 15 minutes. And it didn't help at all. Hoping changing the ECU will solve the problem.
