Hi all,

I have a B16A which i have converted to OBD1 and now i am Using it on P30 EDM.

I want to ask which ECu will be batter to use,

P30 EDM,
PR3

I have them both,

Thanks in advance,

 

Either one can be programmed with crome, hondata, or uberdata...it makes no difference.

 

I forgot to mention that i also have chiped PO6 with VTEC,

 

well i know the the pr3 has a higher redline limit as well as a vtec that kicks in sooner then the pw0, i think the p30 is just like a pr3 for obd1?

 

In a Pr3 that Vtec kicks in at 6200 while at P30 the vtec is at 5500,

Yes and no. An OBDI PR3 actually exists (1992-1993 Integra XSi).

 

soo its batter or not.

 

obd1 pr3 and p30 are the same ecu, i know, i have both

 

I dont think they are same, P30 fueling is richer then PR3, adn vtec points are also diffrent,

 

The run the same engine from the same years......just come out of different chassis.

 

As for me i have a B16a which have pr3 obd0 with it,
I converted it into obd1 and i was using p30 on it,
I have just exchanged it with obd1 pr3 from a friend,

My car is a Ef3 civic hatch, with I/E

 

i have a p28 ecu is this a good ecu for a b16a2 our would a p30 be better?

 

p30 is batter then any Sohc vtec ecu, and also Dohc vtec,
Reffering to the one with out IAB"S

I am running PR3, i am feel that the voice of the vtec is a low as it was in p30,

Is it really happening or its just my imagination,

most likely yes. but yu can get it chipped to run with the b16a
fuel and everything is different for z6 compared to b16

what in the hell is your infatuation with the "sound of vtec"? i swear every post youre saying something like "stock gsr cams willm ake my vtec sound different than stock b16 cams."

1. get p28 or basically any obd1 ecu
2. identify the 26 pin chip specified on the crome site
3. grow some nuts
4. get a low voltage iron and a solder sucker
5. go to town until it falls out.
6. insert 26 pin zif socket
7. call tuner and say "hey i have a stock obd1 b16, need a crome chip for it, its stock, i just want a 5100 vtec, 8200rev limit, no knock and no o2. oh yea, try to get me as closeto about 12:1 straight across as you can guesstimate by teh info im giving you. can i pick you up anything form taco bell"
8 insert said chip into said zif socket
9. enjoy "the voice of vtec"
