How do you guys blocked the EGR/intake hole? what will happen to the EGR solenoid after removing it? does it make gain or anything?

you can make a block off plate or buy one off of ebay. you will throw a code if still running ur p13/p14. but running a p28, you wont throw one.

 

i did not find one from ebay, but i found one from some performance site. its say though recommended for turbo, i was wondering does it work if you got no turbo?

also on P28 chip, is there any requirements before you soldered that thing on ECU? Im new on this ECU mod so that's why im asking these kind of question. What is the diff on P13/14 to P28?

I found one from ebay and im not sure about the description when hey says 450cc inj., 3 bar GM Map sensor. Are these the requirements? Do i need turbo first?

you will throw a code. i dont know what ecu u have. but, I think its just for looks. I dont think anyone sees any real gains from it. what u can do is keep the egr plugged up, and mount it else where in the bay, to make the ecu think its working, so u wont have a CEL...

whoa, what are you talking about? first the ebay link isnt working. secondly, how did you go from talking about the EGR valve to a 3 bar MAP sensor? and what are you talking soldering to the ecu. put down the crack pipe for a second and let me try to help you.

 

Quick question, I am doing this next week. Got my EGR plate coming. Will I throw a code on a 92 Si h23? What stock ECU do I have?

 

LOL@the crack pipe. Just leave your poor car alone. there are some DIY stuff you could do, but your apparently getting into something you have no idea about. do some searching and figure out exactly what You yourself want from your car, then ask to how to go abouts achieving that (not trying to bitch at ya) But as far as the map sensor, larger fuel injectors and other stuff you were questioning about, yes you would probably have a turbo system in order to require those extra mods. As far as if your car is stock you wouldn't need to do those componets really.

You won't throw a code on OBD1 as long as the EGR is still plugged in.

ur ecu is a p14

 

That's the reason why i was asking. egcoupe94 said I need p28 ecu and did some research and showed that it's a stupid memory chp that goes to the ECU. SO HOW DO YOU KNOW IF IT"S P28? I HAVE OBD II since my prelude is 99.

 

A P28 is not a stupid memory chip. It is a ECU out of a 92-96 Civic Si/Ex and the Del Sol's with the D16z6. The P28 is very tunable and does not have the sensors that the H series ecu's have. It is a very good for turbo's and other types of N/A builds. You can't just plug and play, it will have to be tuned with a H22 basemap or whatever motor you want to use it with.

This is a P28:

What if you are running hondata with a p72 ?? Do you need it plugged in or can you remove it completely ? What about the rest of the system ?

 

So what type of ECU is the 5th gen SH has? Does that one has same connector type or u need to have the adapter or harness conversion? P28 works on SH?

How do you tune that where that is a factory ECU and does not come with the cable so that you can load the 5th gen SH basemap?

 

If you want ecu or ecu chipping I recommend you check out

http://www.moates.net
http://xenocron.com
http://phearable.com

If you are wanting pure speed this mod won't do to much and if you live in an area with smog restrictions then leave it alone.

Search is your friend for sure.

 

I went to one of those sites and went to product section. They are selling chip for p28. Is that mean p28 ECU would not stand alone with out those chipping MOD?

 

Right, they have the pieces for you to chip it yourself or you can send it to them and have them chip it (highly recommend unless you have the tools and patience)
They can even put a chip in there that is a good basemap for your specific engine.

Although I would check into a P72 (obd1 GSR ECU) as they have the IAB (intake air butterfly's) that would work with the H22.
Not sure if obd1 H22's have knock sensor or not.

Then you could use crome free or something if you are running rich/lean to help solve the small issues.

With the way technology and tuning has gotten to it is not hard to make adjustments to your engine to run it a little safer/faster/more mpg whatever.

bump

 

what about buying obdI H22 and mod it to p28 or p72 would that work? The first thing i am concern about is the ATTS sh*t since that thing has sensor. And, also the thing that doesn't make sense to me is that u said P28 ECU is from CIVIC EX and they have SOHC engine VTEC. is that the reason to MOD IT?

I am new with this ECU MOD man and I appreciate your response. Im maily focus on the engine work so im not so good about ECU mod. My plan is that not putting turbo on it just normal tuning and some add on stuff. So I am looking ahead to this ECU MOD cuz might help little to get my lude running better.

Would you recommend to get OBD I H22 and MOD it or just buy P28 or P72?
Isn't it hard to troubleshoot if something goes wrong and you got ECU where sensors got disabled?
