I did a B17 swap in my 93 Del Sol using JDM obd1 P72 ECU. The problem is the car not seem to pull at all, I feel like the timing is retart. When I try my friend P28, and a chipped P72 w/out knock sensor the car run way better than the JDM P72. My question is...it is the knock sensor that cause all this problem?
Thanks for any help

 

Gotta remember that the p72 will be looking for the butterflies.

the p72 DOES NOT look for butterflies. it can control them and is optimized to run with them.

 

educate me here How does a P72 control a butterfly and what is a butterfly anyway?

 

butterflies are in the manifold of the obd2 gsr's... just get another ecu
I may have a stock '92 GSR ecu if u want... it's a p61

 

so the sencondary butterflies only exist on the 94+ GSR manifold? <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by NUB-96EK &raquo;</TD></TR><TR><TD CLASS="quote">butterflies are in the manifold of the obd2 gsr's... just get another ecu

How much do you want to sell your stock 92 GSR ECU email me at nguyend@hawaii.rr.com

 

Is there anyway to dissable the sencondary butterflies in the ECU so it doesn't look for it?

Install the patented "Butterfly net". Hondata make it.

 

i hate those damn secondary runners.......d16 all the way

 

I'm a little confuse now....I have a P72 which control IAB, and I have a B17 manifold which does not have an IAB or secondary runner? So without an IAB I'm lossing some low end torque...In order to make the P72 happy I need to get all the IAB system from the B18C1 and hook it up? or like "Ricey McRicerton" said to install patented "Butterfly net" what is that anyway and where can I find that?
Thanks

 

Why dont you just run an ITR chipped P28? You won't be able to slap on the GSR manifold without swapping the whole head. You are just running an ECU not made for the B17.

 

wait a minute...I got carried away with all these IAB stuff...there is one thing that I don't understand...when I tried the P72 on two of my friend car w/B16 (one is 92-95 JDM B16 and the other is B16A2) both car ran find without hesistation. I've been searching on H-T about IAB topic and everyone is saying that IAB only have on B18C1 and H22. So why does the B16 run find with my P72 and i can't run my B17 with it?
BTW: I've tried both P28 and a chipped USDM p72 and they both run better on my car. Well I can get a P28 and chipped it out, but I just want to know why my car bogging out badly in low end. Could it be the VTEC x-over point is too low on the JDM P72 (I believe the x-over point is about 4500-5000 rpm; not too sure if this ECU was chipped though )

 

the question is, why did you swap in the B17 GSR motor vs a B18c one?

b17 gsr = bad news (black sheep of the honda motor family)

 

on a budget...of course
I know it is an odd ball of Honda motor...but it's a DOHC VTEC...and on top of all motor is motor; wether it's a black sheep or common, if you can get it to run right then it'll be a good challenge for yourself

haha yup budget for sure... im on a budget too. I got a first gen b16 that im swaping most of the parts. OBD1 distriburtor, AEBS intake manifold, GSR trans, etc so basically you would know its a first gen. ^_^

 

I saw the local post that you're selling OBD 1 GSR for a friend

Just run a chipped P28 ecu with a b17 or b16 program on it get a afc and subtract or add fuel were needed.....

Why did you even post this here?

 

c'mon guys motor is a motor...as long it can produce the power to your expectation then it a motor of choice...some people said that B17 is a black sheep because it not as popular as the B18C, and only in production between 92-93 as oppose to the B18C which widely availble from 94-00. B17 is basically the same as B18C just smaller displacement and lower compression.

 

BTW I need an answer to my question not a comment on which motor is better
