OK. Since my 96 is OBDII, is it possible to get the ECU chipped or reprogramed to get rid of the 7200 Rev Limit? I am figuring if I get everything that I am planning, then I should be able to get power past $7200 safely if I get rid of the limiter.

any ideas?

Thanks again.

 

No. OBDII is not programable.

Must convert to OBDI and use a hacked OBDI ECU.

 

aaaaaaaaaasssssssssssssssssssssssss

so does any one want to instruct me on what i need in order to convert? and how difficult this is going to be... and how much its going to SUCK?

P28 and a Clip

 

excuse the impending dumb question but what is

P28?

 

P28 is a SOHC VTEC ECU......they are cheaper than the DOHC's and can be modified just the same.

 

can i swipe a ECU from a wrecked Prelude Vtec OBDI?

or maybe this?

Why do you want to raise your rev limiter? Unless you have cams and the kind of head flow that will make power above 7600rpm, there is no point in raising the limiter anyway...

You do not want to use a P28 ECU on a H22a, chipped or no chip. The P28 does not support control of the secondary intake manifold butterflies and worse, it does not have support for the knock sensor.

You also do not want to use an P72 ECU that is chipped for a DOHC VTEC B series motor as the ignition and fuel maps will not be good for an H22A. Your best option is a P13 ECU chipped to raise the limiter.

Does your '96 have the peak and hold injectors?

See his sig.

 

Well. I plan on getting everything that is in my Sig..
This is the package that I plan on getting from JG
also plan on getting crower cams


and I dont know what my injectors are..

 

OBD2 is reprogrammable, however it does cost quite a bit which makes
chipping an older ecu and getting an adapter harness, especially if you want
to get a new program later on in the future it will be much cheaper.

 

Check out the http://www.hondata.com site. They might be able to help you out!

 

i just saw that you have a prelude. I wouldnt recommend revving much past the
stock redline. the transmission has a real hard time shifting after that.

 

My bad. I'm on here at work, and I have all the display sigs, avatars, pictures, etc settings set to "off". So I did not see his sig...

I've never heard of that problem before... Can you please elaborate?

Andrew

 

ok... Hondata site says the p72 is the best swap for ecu..
So if I got a hondata stage2b (since I plan on running nitrous in the future)
and found a p72 and got the harness... that should be all i need right?

 

Correct. Harness and ECU.
