one area i'm lacking in knowledge when it comes to preludes is the ecu setups. can anyone give me a run down of what ecu setups are being used and for what applications. any information would be appreciated, thanks.

 

What specific information are you inquring about?, the whole ecu or how your ecu operates?

 

OBD 1 seems to be the best way to go, and your options are:

Honda P13, limited tuning capability but better than OBD 2
Honda P28 or P72 can be chipped to control H22 quite well
Honda P28 or P72 with Hondata to run boost or fine tune
AEM standalone, getting better as more people start using it

i'm asking what ecu setups are being run your preludes, p13,p28,p72. hondata, chipped, what is a good setup for na, boost etc., etc.

 

i personally am running a p28 w/ hondata, untuned and the car is NA. i wish i had gone with the p72 tho cause i really want my knock sensor back...the secondary runners dont really make much of a difference tho.

 

I'm running the same P28 w/hondata S200. If you get hondata, then you can run any honda 4cyl. n/a boosted etc..... All you have to do is upgrade the hondata to tune boost

Its not the cheapest way to do it, but I say that it made my car faster with just the obd1 swap & hondata with street tuning.

Edit: I also planned on getting the Skunk2 intake (without secondaries) but even without the secondaries working I really cant tell the diff.

I have an OBD 1 P28 ecu (controls VTEC) from hondata for sale: First $200 takes it. It has the rom socket installed and the connector for the Hondata link box. Will work with stage 2, 3, 4, and the new S200 stuff. It will also work with aftermarket roms (like the ones on ebay) if you prefer to go that route. Just plug the new rom into the socket and you're good to go. Here are a few pics:

alright i found this in the for sale forum and wanted to know is this a good price/ worth the money and can i run this on my lude without a s200 if he has already programmed to run a lude? also will be able to run this ecu and still use secondary runners?

 

If your going NA, and not going to crazy on the internals, then the stock ECU with an Apexi Vafc will work great.

If your boosting then Hondata (obd 1), or the AEM ECU.

 

So if someone went with a p28 GSR Mugen program, would they need Hondata as well?

I'm not an expert on the matter but the Mugen ECU is programmed for the 1.8 liter B18C1 for air/fuel and rev limit. From what I heard it can be ok on an H22 but isn't tuned specifically for YOUR car. I'd say it's good for bolt-ons and that's about it. Past that it would be useless because you can't tune it past what it already is (at least by itself).

can anyone back this up because if it is the case it will save me a good deal of money.

 

No backup, but this is what I plan on doing when I get my motor back and installed after the rebuild. VAFC and a dyno tuning later this summer.

 

So if you had a choice to go with a p28 chipped ECU or hondata, which one would be best for going n/a?

 

I have a 5th gen, and will probably do very little tuning at this point. I doubt I will get into any internals for quite a while.

In the mean time, I will just do the bolt ons, followed by SS braided brakelines and a suspension setup, maybe pulleys, cam gears, etc. I may do something with my flywheel and clutch after that.

I've got an offer on a P13, would this be the right ECU for me?

The p13 would be ok in your case, but your gonna be kicking yourself later if you get the p13 then have to sell it and look for a p28/p72 (if you ever wanted to run hondata)

Why would I kick myself? I see p13's go for good $$$ on ebay all the time. ^_^

What car does the P28 come from? Isn't the P72 a GSR ecu? Wouldn't both of these require you to run additional hardware like a hondata?

thx

I can back it up with dyno plots, and o2 readings. The stock ECU with some slight tuning at WOT with VAFC is all you need, and it works great. Why do you think you even need a different ECU?? Honda's PGM-FI works very well. Is your fule too lean or too rich? Are you getting detination? Are you runing under a condition that the stock ECU does not know what to do with (ie, boost)? I bet not. Tust me, save your money and don't fix a problem that does not exist.

I just say that from my own experience. I bought an ecu that I dont even use anymore(p13), but its not just because of hondata(cant use a p13 with hondata)........I mean sure you can get ecu's chipped an everything, but what if you do decide to get cams etc. The fuel and timing maps could be way off. Sure you can buy a vafc, but that still leaves your timing out of the equation(sp?) and timing is very important to the way the engine accelerates/runs. Instead (if you get hondata) after the hondata is tuned, then you have a custom chip that makes YOUR car run perfect everytime. Sure it will lighten your wallet, but if its worth doing......then its worth doing right!

Edit: p28 (92-95 civic) p30 (delsol Dohc Vtec) P72(gsr)
The main benefit of using the P72 or p30 is the they have the knock sensor. Plus the p72 will run your secondaries on the intake. But if your car is tuned correctly then you shouldnt need a knock sensor.
