Aight, I swapped a b18c into my civic coupe a few months back. I just got around to wiring in the IAB. I dont htin kit did anything. Actually it may have but i dont hink its working now.

Tonight i went out cruising, and i lost to a bone stock 240. I was pissed. I get down into my ecu and see that my ECU pin for my IAB was all the way in. Apparently there are different types of pics for different applicatiions? I ran the wire to a17.
So RIGHT after that happens. I no longer get VTEC at 4500 and now i hear a tone change similar to VTEC around 6000 were the secondary butterflies should be opening.

My coupe is not nearly as fast as the other coupes i have bene in with the same exact swap. I lost to a ******* stock 240 and a prelude tonight for christ sake.
My firend has a GSR integra i race him a few nights ago and pulled a good distance on him, Tonight we run and i am hard pressed to pull inches on him. shifting EXACTLY when he did side by side. So when i disconnect the IAB wire i stert getting VTEC at 4500 again.

Guys i dont know what the ****. I know i need new spark plugs and imma get those tomorrow. but i know thats completely unrelated. Also i was NOT low on oil.
i dont know WHAT THE **** is going on. I would appriate any help,

My set up is'
94 coupe
obd1 GSR.
p72 ecu
CM stage 3 clutch and a friggin intake.

 

what model of coupe? i know the EX should come prewired if you use a gsr engine harness, with the EX harness you have to do some rewiring, or better yet extending wires.

i was changing a engine harness for my cousin a few months back and he has a dx HB with a gsr engine, i can quite remember which wire i hooked up, but everything works perect until i blew his secong gear racing a ITR.

 

I have an EX.
I esed the EX wiring harness and ran wires for the knock sensor and just ran the wire IAB and i thought it was working. Last night, i pulled it out and and it wasnt hardly in place. So i pushed it in further and drove off. Atthat point iw as not getting a VTEC tone change untill 6 grand, Either it was my VTEC kicking late. Or my SEcondaryes and i have no VTEC. i dont know whats happening.

 

Anyone?

 

just because he said he is bone stock dosent mean it is.

and you should hear a VERY audible change at 5700 with the butterflies open.
vtec turns on at 4400 then the IAB's work at 5700.

 

Just but a Skunk2 intake manifold and F the secondary crap. Thats what i did even before I put the motor in and I never looked back.

 

Yes, The secondaries opening was very audiable. but no vtec tone change or and extra power from vtec for that matter.. And i know the guy with the 240 intake and a glass pack is all he has....

 

still nothing fellahs>?
