I have a 92 civic vx with a 96 gsr swap. I bought the car about 3 1/2 years ago (Didn't know anything about cars then just like it cause it was fast.) I have learned a lot since then and work on honda all the time and have done a fair amount of swaps. Any way the car has never given me any problems until I put a v-afc in. The car has the entire 96 gsr harness under the dash and in the engine bay. Since I installed the controller the car will cut out at around 6300 RPMS. It is like the rev limited is moved to 6300 and the car seems to run a little slower. Everytime I turn the key off and turn it back on it will rev the whole way. I have checked the wiring and so has a couple of my friends(they were ASE certified) just to make sure it was right. Everything fine there. I swapped ECU with my friend and still same problem and the ECU never did it in his car. I swaped the v-afc with a friend and it still does this. No check eng lights except for the sec O2 sens that is not installed. Can anyone here help me with this one.

 

Try instaling the sec o2 sensor... That could be it.... Im not verry knowledgable, but it would seem to me that the best thing to do would be to look at what the STOCK GSR motor had when it was in the TEG and make sure you have it all in der.... If it still dont work its beyond me. But if it were my car I would start there.

 

have you followed the instructions Apex gives you for setting the VAFC up for your motor for the initial startup?

 

Yes I did. I have installed about 5 of these controllers not counting mine but I am the only one with problems.

 

That lower revlimiter means the ECU is not engaging VTEC. I would look into the VTEC solenoid and pressure switch wires, and make sure they are all hooked up correctly. If you have access to a Helms manual, I would double check all the pins and make sure they are correct, because I remember some of the Apex'i ecu pin diagrams are a bit wrong. Good luck,

And if you do decide to burn it, can I have some parts, :thumbup:

 

I'm not trying to be a tool but why the hell would anyone in there right mind change the entire harness over to accomadate a bolt in plug and play swap, you say your throwing a code...the only way to do that is to be using the OBD 2 ecu in your car...the person who did that swap really should not have gine through all this trouble. When you wired up the VAFC you did look for the OBD2 corresponding wires and verify each wire w/ a DMM correct...if not you my friend have a headache and a wiring issue...I wish I was closer I could probably fix that for you.
ASE-automotive service excellence-not the HARDEST test to pass so that doesn't mean too much. Find an EXTREMLEY competent installer in your area and have them double check the wiring. Good luck.

 

My car has an OBD 2 ecu and I did install the controller right. I have had about 3 different people check it. I know a lot about cars and I can do everything execpt body work to them. I know the swap was made a lot harder than it really is. However I bought the car with this engine and I was clueless when I bought this car. I have just recently swap a gsr motor into a 97 civic lx. I had to convert from auto to a 5-speed and put skunk2 intake manifold, AEM cam gears and many other bolts on onto this motor. I have taken it to a local shop called dynamics (Which is an EXTREMLEY competent installer) and they told me they have never heard of anything like that from installing a VAFC. But thanks for your input and if could ask a couple of people that you think are competent installers and see what they think that would be great and I wish I could find some good luck.

 

what that means is the ecu is in safe mode. it is NOT getting correct input from yout sensors. either the MAP sensor, the TPS or the vtec wiring is not done right or the vafc is defective. I had the same problem, i could get the vafc to cause vtec to engage but it would not rev over 6300 ro so....that was due to the fact that i had the map sensor wired wrong.

 

Take the damn thing off . . .then it will run like it used to

 

Instead of taking it off I could just buy a calvier z24 and never have this problem but then I would have the problem of my car looking like a huge pile of crap.
